PM Update: More rain to come before a clearer and warmer tomorrow

A day we don’t usually see in meteorological winter (Dec.-Feb) will go down as one of the wettest. In fact, the 1.12” (through 3 p.m.) makes this the rainiest we’ve been since the record breaker of 3.10” on December 7. We have not quite made it to the Leap Day record — well, Dulles and BWI did — of 1.61” in 1892, but there’s still some more water to come before it’s all over.

Leap day weather: new rainfall records set at Dulles and BWI airports

Occurring only once every four years, weather records for February 29 are necessarily limited. For example, the number of leap days on record at Dulles airport is just 13, since observations began there in 1963. Thus, it’s not surprising that today’s old rainfall record of 0.51” from 1968 was easily passed today. The airport has received 0.99” so far.

Killer storms slam Midwest, head into Tennessee Valley

At least 9 people are dead after a severe thunderstorm outbreak raked portions of the Midwest Tuesday into Wednesday morning. Hardest hit were southern Illinois and Missouri where apparent tornadoes ripped through the towns of Harrisburg, Il. and Branson, Mo.

As cherry blossoms promise an early bloom, some pre-spring gardening tips

We are just beginning our most floriferous time of year. Of course, one of the main treats in Washington, D.C. will be the bloom of the region’s cherry blossoms. This is the 100th anniversary of these trees coming to the Tidal Basin so it should be quite an event.

Sensational Leap day sunrise

The sky took full advantage of February’s extra day, serving up a flavorful morning sunrise around Washington, D.C. As clouds from the incoming weather system streamed in from the west, they were intercepted by the rising sun’s glowing rays. The sky lit up in fiery yellow and orange hues, before it completely clouded over into a uniform, dreary gray. Enjoy these photos!

Forecast: Bumpy weather ride starts with chilly rain today, then mild tomorrow

Quite an active weather pattern we’ve got here over the next several days. From a chilly rain today with thunder possible this evening, we swing back to sunnier and warmer times tomorrow. Much of Friday is pleasant, but then shower chances return late Friday into Saturday. Today and Sunday should be the coldest days of the bunch, with fairly mild weather in between.

PM Update: Wet Wednesday on the way

Until the middle of the afternoon, the region enjoyed clear skies, which boosted temperatures into the mid-50s. Some high clouds are starting to filter in, and they will gradually increase tonight. For Wednesday, both a warm front and cold front come through the area, bringing rain and cool temperatures.

Toughest places to forecast weather: a match for Washington D.C.?

From trying to nail down the rain-snow line in winter to predicting the timing and location of pop-up thunderstorms in summer, the fickle nature of D.C.’s weather presents problems for even the most seasoned forecasters. What forecast challenges do other regions contend with? Are they as difficult as Washington, D.C.’s?

Severe weather to strike central U.S. and Tennessee Valley, a precursor to active March?

A powerful storm system will move across the middle of the country today and introduce a chance for severe weather, including tornadoes, over a large area from the southern Plains to the Tennessee Valley. Given the impressive tornado numbers so far this year, and the fact that La Nina is expected to be in place until mid-spring at least, it might be tempting to think we’re lining up for another big year. Not so fast.

Drier weather returns Thursday-Friday before more rain returns for Saturday with a cooler, drier Sunday to follow.

What a delightful day this turned out to be. Wall-to-wall sunshine assisted temperatures in reaching the low-to-mid 60s with just a light breeze. A weak cold front sneaks through the area tonight, just shifting winds to come from a cooler direction. Tuesday remains sunny, but temperatures drop about 10 degrees.

Daytona 500 weather forecast: promising for Monday night race but no sure thing

For the first time in its 54 year history, the Daytona 500 was postponed due to weather Sunday. The race was initially rescheduled for noon today, but was pushed back to 7 p.m. tonight after more showers. As race time draws closer, it’s still not clear if weather conditions will allow it to proceed.

Washington D.C. weather: Is it a forecasting nightmare?

Whether it’s extreme heat, extreme cold, blizzards, hurricanes, severe thunderstorms, tornadoes, droughts, floods, or just plain high winds, Washington experiences an incredible range of weather conditions. But is D.C. weather really more difficult to forecast than elsewhere or is that just an urban myth, perpetuated by mean-spirited cynics?

Forecast: Sunny, pleasant start to week, but chilly rain Wednesday

The last several days of February will bear close rememblance to the rest of the month: generally milder than average but with a tease of winter thrown in. The wintry tease this week comes Wednesday in the form of a raw, cold, rainy day. Thursday and Friday then look great before some milder rain showers Saturday.

Forecast: Light winds today, mild tomorrow. Midweek rain?

Plenty of room for improvement after yesterday and we’ll do just that with far less wind and more sun. Conditions get even better as we start the work week (figures) with continued sun and temperatures closer to 60. By midweek, though, we’re looking at a good chance of rain, and another temperature forecast made tough by a warm front.

More wind is the main story today, with gusts near 40 mph. While the wind has some wintry fury to it today, temperatures this weekend don’t have a terribly chilly punch, though they’re certainly colder than the past few days. Our brief cool down doesn’t last long, however, as the winter that wasn’t continues...

Temperatures significantly underachieved today, only reaching the 50s to near 60, rather than the 70+ forecast (except in the southernmost parts of the region). Intermittent rain showers cycled through, and even some heavier thunderstorms in southern Maryland. Now the winds will pick up significantly as a cold front blows through. A wind advisory is in effect.

Big cold front bringing rain, storms then big winds (LIVE BLOG)

Temperatures have clearly underachieved today, only reaching the 50s in the immediate metro area after forecasts of 70s. The cool wedge over the region has squashed the severe thunderstorm potential for D.C. and points north. However, as close as by as Stafford county in Va. and St. Mary’s county southern Maryland, temperatures have reached 70 (not to mention 80 in Richmond). It’s that area and points south under the gun for heavy thunderstorms this afternoon. Once the rain moves through the region, then howling winds blow in along and behind the cold front.

D.C.’s longer daylight hours mean spring really is just around the corner

A balmy 60-degree day in early January might feel like spring, but when darkness falls around 5 p.m., we’re inevitably reminded that it is still winter. Now, at least, we’ve got the longer daylight and higher sun angle to accompany our spring-like temperatures, even if they are (once again) several degrees above average.

Forecast: Warmth before shower and storm potential, then very windy

Today is a warm, showery, and eventually windy one. It just may be tricky to drive high profile vehicles after the front whips through, not to mention debris (like sand) blowing into our eyes. Once this cold front gets through the region, we have a couple cooler days, as breezes abate for Saturday night and Sunday. Overnight lows closer to freezing this weekend, though, may have you reaching for that buried winter coat! Not for long though, as temperatures next week could meet or exceed the 60 degree mark. Ah, what a non-wintry February, eh? (Allergy sufferers say: achoo!)

PM Update: Very mild but turning very windy Friday afternoon with shower/storm chance

Sunny skies for much of the day have given way to some clouds ahead of a warm front that will punch through the region tonight. The front may produce a few showers tonight, before even milder air blows into the region, but just briefly. We may surpass 70 Friday but then howling winds brings in colder air for at night into the weekend. The wind is a big deal and has prompted high wind watches west of D.C. and a Fire Weather Watch for much of the region.

Forecast: Spring warmth blooms today and tomorrow, chill down this weekend

Yesterday was just the warm up, pun intended, as today makes us all long for an early dismissal from whatever keeps us indoors. Friday also promises another temperature treat but a stronger breeze makes it a bit harder to appreciate and showers may arrive in the afternoon. This sad excuse of a winter tries to bully back in for the weekend but the best it can do is knock highs down to just below normal.

Partly sunny skies dominated the day, and the fact that spring is creeping ever closer might have been apparent if outdoors.

March outlook: Warmer than average, low snow chances

The warmer than normal winter is expected to continue into at least the first two weeks of March and will probably last through the month. That doesn’t mean there won’t be quick shots of colder than normal weather but that there is unlikely to be sustained cold. And snowstorms will still probably be hard to come by.

Forecast: Warm streak with shower chances before weekend cool-down

As gas prices keep rising, at least this mild winter is giving us a nice break on home heating costs. The savings really add up today through Friday with highs from near 60 to near 70, and lows tomorrow night higher than our average daytime highs. With the warmth comes a few shower chances and maybe even a thunderstorm. We chill out this weekend, but only back down to around seasonal norms.

Variably cloudy skies tonight and brisk, but about 10 degrees milder than last night. And Wednesday afternoon we warm another 10 degrees relative to today. Onward and upward!

Is winter over for most of the U.S.?

For places like D.C., Philly, New York, and obviously points farther south, winter may well be about over (not that it really got started). With a mainly mild and wet close to February, and longer-range models predicting mostly warmer-than-average weather during March, I don’t think odds of adding to the meager snow totals along I-95 corridor are good. That’s not to say winter is over for everyone in the country. Far from it. There are some places that are staring down some nasty cold before the turn of the month.

After a largely snowless season, last week there was considerable build-up for the possibility of snow Sunday. But with the exception of Springfield and points south, there wasn’t even a dusting. Some have questioned whether forecasts were overblown for Sunday’s event. But we want to let the record show our forecast was for little or snow in the immediate metro region, starting Friday night.

After some relatively colder air over the weekend, we are on a trajectory toward big-time warming in the days ahead. After mainly 40s yesterday, look for 50s for highs in most spots today. Tomorrow, most areas should acheive the 60s, while we could reach or exceed the 70-degree mark on Thursday ahead of a big cold front on Friday.

Some snow lovers held out hope for some unlikely snowflakes Sunday. But unless they resided near Fredericksburg or farther south, they were no doubt disappointed. The upcoming week offers little promise for snow, but warm weather fans will smile, much like they have all winter. After some “chilly” upper 40s today, we’re mainly in the 50s and 60s through Friday. It probably cools down some next weekend.

Update: Still a chance for some “conversational” snow, mainly this evening

Don’t be surprised to see some steady snow, perhaps a coating to an inch in D.C.’s southern suburbs this evening. Around the beltway, I’d expect any flakes to be more conversational, with little or no accumulation. The most likely timing would be between 6 and 10 p.m. tonight. North of town, probably just flurries, if that.

Forecast: Snow may be mostly a no-show

As we’ve indicated was quite possible for several days now, little to no snow looks to be the most likely result as a storm tracks mainly to our south this afternoon and evening. Snow lovers are surely crushed, though we still can’t rule out a light accumulation. The storm’s effects do help to keep us on the cool side today. But then it’s right back to business as usual this winter with early-to-mid week highs climbing near and past 50.

Sunday snow probably won’t be much, but minor forecast changes still possible

We’ve been highlighting for several days now the significant chance that tomorrow’s storm tracks too far south to deliver much snow to the area, and as of this afternoon that continues to be the case. The models have mostly now locked in on a storm track that would give the D.C. area 1-2” inches of wet snow at most, with no snow (or at least no accumulating snow) a possibility as well, especially from D.C. to the north.

Forecast: Springlike today, but will snow still threaten tomorrow?

If you like snow, you probably were not a fan of the deflating news coming across the wire yesterday. But, with the way things have been this winter, it probably is not a total shock that snow can be hard to come by around here. We’re not “out of the game” just yet, though the odds for snowfall of note have dwindled. We’ve still got to watch the evolution of the storm nonetheless, as small changes can bring varied results, and we’re livin’ on the edge.

For yet another day, February brought us milder than average temperatures, passing the 50 degree mark. Saturday is no different with 50+ afternoon temperatures likely for the 10th occasion this month. But Sunday is another story. A cold front drapes itself over the region as low pressure approaches from the southwest, bringing a chance of snow, or possibly rain.

Inside a nearly impossible winter weather forecast

Last night, the models seemed to converging towards a snowy solution. It looked like there was a decent chance of meeting winter storm watch criteria. However, today’s runs paint a different picture as there continues to be model chaos. Even the question of precipitation type has not been completely resolved. The overriding unresolved question is how much snow will the storm produce and if it does now how much will stick. Both these questions are very much up in the air as very small changes in the storm track can make huge differences in the amount of precipitation it produces.

Sunday snow situation: could be boom or bust

During the day yesterday and last night, it looked like models were coming to consensus that we would get significant precipitation Sunday, and at least some of it in the form of snow. Now, it’s not as clear. As the impressive southern storm moves from the western Gulf of Mexico to the North Carolina coast, precipitation will have a sharp northern cutoff. Whether that cutoff is in D.C. area or southern Pennsylvania will make all the difference with respect to the kind of weather conditions we experience Sunday.

Accurately measuring snow: a critical winter weather challenge

Let’s assume there will be measurable snow on the ground by Monday morning. How do we most reliably figure out “how much?”. The answer to the question is not as straight forward as one might think.

Forecast: Sunny and warm into early weekend; Sunday snow odds up

Most of you are probably here hoping to see how much snow is in the forecast. We’ll get to that, but first we’ve got to address today and tomorrow, then enjoy it. Enjoy being the operative word with plenty of sun shining down and temperatures up into the 50s. Our developing Sunday storm looks primed to threaten the biggest snowfall this nearly snowless winter season, but with details still on the sketchy side, certainty isn't a part of the forecast yet.

Update: Sunday storm shows increasing snow potential

The models coming in this evening, thus far, have trended colder - which is critical for Sunday’s snow prospects. And while some earlier model runs showed the storm just grazing us, according to this evening’s runs, it now delivers a pretty good blow. So it looks like the necessary moisture and cold air may be coming together for accumulating snow Sunday. But - with the storm still 60-70 hours away - significant fluctuations to the forecast are possible.

Today was showery and gray, but the last of the rains have moved off, and conditions improve to close out the work week. Some patchy fog may form tonight, but sunshine Friday burns that off with relative ease. Temperatures will continue to be solidly above average, with Friday’s highs into the 50s.

Since 2006, nine in 10 Virginians and four in 5 Americans, have lived through extreme weather events ranging from unusually severe blizzards to torrential tropical storms. A new report from Environment America, tailored to local areas, warns that global warming could lead to similar disasters becoming more common in the future.

Forecast: Showery Thursday; still questions on weekend storm

The sun takes a hiatus today with cloudy skies and showers mainly in the afternoon. Fairly mild conditions push high temperatures to the upper 40s and low 50s. Sunny skies return tomorrow to end the week as temperatures rocket back up into the mild low-to-mid 50s. Saturday is looking decent with partly sunny skies and more 50s. Question marks begin for Saturday night and Sunday as various models argue different scenarios, but they are trending stormier.

It was quite a beauty though today, tons of sunshine and little to no bothersome wind. Hope you enjoyed, as tomorrow won’t be nearly as nice.

President’s Day weekend: To storm or not to storm? To snow or not to snow?

The potential exists for a major East Coast storm this weekend, but it’s just as likely the storm passes to our south, harmlessly out to sea. Even if we get a storm, it’s not clear if precipitation would take the form of snow, rain, or some sloppy combination. In other words, right now we have more questions than answer.

Forecast: More 50s on the way. Could snow sneak into holiday weekend?

We’ve got a chance to reach or surpass 50 degrees each of the next four days (though tomorrow may fall just short). Can’t always say that in mid-February, but it’s par for the course as this winter goes. Anything that falls with a system coming through tomorrow will be in the form of rain. The holiday weekend, however, could be a different story. Emphasis on the could though.

Long range look: a mild and wet finish to February

According to the weather model consensus, a westerly flow of mild air has begun to flood western Canada in a way that will soon allow a broad cyclonic (counterclockwise) flow to develop west of the Continental Divide. This will provide relief from the recent frigid temperatures in the Plains, and more likely than not, set the stage for …and winter lovers will hate this… a mild and wet finish to February.

Another iffy snow threat in the offing

Yesterday several computer models suggested there was a chance of a snowstorm Sunday. Now, several of them are backing away from that idea. The most we can now say about this weekend is there is a chance of rain or snow, but it’s even more likely the entire system stays far enough to our south that we remain dry.

February, the final month of meteorological winter (Dec-Feb), features plenty of cold air many years, but also a hint of what’s to come in the months ahead with a hint of milder times. On average, precipitation remains at a cold-season nadir. Still, the month has provided many memorable snowstorms.

Goodbye serious cold! After morning temperatures in the teens to mid-20s, we rebounded very nicely today under mostly sunny skies and light winds. Afternoon temperatures in the upper 40s to near 50 are pretty close to normal for this time of year, and there’s no sign of really cold air in the near future at least. We’re keeping an eye on a little moisture for tomorrow, and the keywords there are probably “a little.”

What do new findings on ice melt and sea level rise mean?

A new study on melting glaciers and ice caps has received quite a bit of press attention, some of it rather confusing. While the paper (technically a letter) published in the journal Nature, concluded that glaciers and ice caps worldwide lost about 4.3 trillion tons of mass between 2003-2010 - enough to cover the entire United States with water 1.5 feet deep - there were some regions where glaciers and ice caps did not lose nearly as much ice as previously thought.

In terms of a bitter combination of wind and cold, winter may have reached its bottom Sunday morning.

The transition is a little choppy, with opportunities for rain and some more wet snow flakes Tuesday and Thursday.

Forecast: Arctic front threatens heavy snow showers, brings some of winter’s coldest air

Some of us are waking up to white ground this morning after light snow targeted mainly the north and west suburbs overnight. That snow may melt off today as temperatures climb back up a bit ahead of the Arctic front that’s inbound. You’ll know it’s here by one of three ways, and perhaps all three: increasing wind from the northwest, falling temperatures, and snow showers or squalls. While the most intense snow squalls may be hit-or-miss, any place they hit could pick up light accumulation rather quickly.

Saturday’s blustery with falling temperatures late along with possible snow squalls after dark. Sunday’s breezy and quite cold, but probably precipitation free.

The second, Saturday afternoon and evening, offers the chance of rain showers changing over to snow showers as temperatures rapidly fall, possibly creating pockets of slick travel Saturday evening.

Forecast: Sunny and mild before the coming storm

Our return to a pleasantly mild winter concludes today but we can probably crack 50 once again with some early sun. On deck though, another light wintry mix event is possible tonight and tomorrow with temperature issues once again throwing doubt into the equation. Much like this past Wednesday’s storm, we’re cold enough aloft, but just a tad warm at the surface. However, the incoming cold is much stronger this time and could be enough to get that changeover across the area before precipitation chances depart.

PM Update: Wintry mix departs early evening, some slick spots possible well north and west

Snow, rain and a rain/snow mix continues across the area, and should do so for the next few hours before tapering off from southwest to northeast. As with most of our snow events this year, elevation and being north and west of the city has been critical if you’re looking for accumulation. Once above about 1,000 feet to the north and west, snow has stuck on the order of .5-1” thus far with more to come. That quickly falls off to dustings and coatings at lower elevation in the same areas, and nothing further south and east.

Will winter 2011-12 deliver a major winter storm? Maybe, but not today. We do get ourselves a taste of the white stuff, though, starting between late morning and early afternoon. Light to moderate snow, possibly starting as or mixing with rain from D.C. to the south and southeast, might be just enough to whiten the ground for some, and cause some evening commute headaches as well.

But that streak most likely ends tomorrow, as a little disturbance zips through the region, offering up a period of light snow - primarily in the afternoon and evening. Accumulations will mostly occur in the colder west and northwest suburbs.

Unseasonably cold air to blast eastern U.S. this weekend

After a few mild, spring-like days this week in the East, a cold shot from Canada will move in for the weekend and deliver a brief dose of February for a change. It does seem a little odd that an upcoming 2-3 day bout with chilly air – carrying temperatures perhaps as much as 8-16°F below average- deserves headlines. But given that winter 2011-12 has so far given us a temperature map like this, a cold snap of any kind is worth discussing.

Light snow likely Wednesday afternoon; could impact PM commute

A weak area of low pressure will drift through the metro region Wednesday afternoon, producing a period of light snow. Temperatures in the immediate metro region will tend to be above freezing, limiting accumulation to primarily grassy areas. The farther north and west you go, the colder it will be, and thus, the more predicted accumulation.

How about that wall-to-wall sunshine today? The increasing sun angle is becoming more apparent by the day, and it helped temperatures in the low-and-mid 50s feel even milder than they were. We’ve got another in our lengthy streak of above average temperatures coming tomorrow. Enjoying it or longing for snow?

Rains ease Texas drought, long-range outlook still pessimistic

Above-average rainfall during December and January have helped ease the Texas drought in some areas. But other parts of the state are still facing water restrictions, and the Texas rice industry is bracing for the potential loss of an entire year’s worth of earnings.

The Full Snow Moon comes Tuesday, and see the far side...

On Tuesday, February 7, the Earth facing side of “Full Snow Moon” will shine brightly in the night sky. And thanks to NASA, close-up views of the moon’s other side, are coming online.

Snowmageddon from space two years ago

Two years ago, Snowmageddon, one of the D.C. area’s biggest snowstorms on record, finally came to a close in the late afternoon. That was after dumping a mind boggling 18-32” of snow over the course of about 30 hours. The storm shut the city down for days and is etched in the memories of all those who lived through it.

Forecast: Chilly week ahead, but still above normal; dry mostly, just a few raindrops or flakes

Compared to last week, this week feels more winter-like, but with highs most days reaching well into the 40s, it’s not exactly bone-chilling cold. We’ve got a streak of 14 straight days with above average temperatures and it may take until the weekend to break it. For the most part, the weather is dry, but some light rain or snow showers can’t be ruled out Wednesday.

Forecast: Highs remain near to above average with minor precipitation threats

Clearing skies later today lead us into a mostly quiet, but not completely uneventful early-to-mid work week. Temperatures head back to near and past 50 Monday and Tuesday, with a few sprinkles or flurries possible tomorrow and perhaps some light rain or snow Wednesday. We’re not too worried about accumulation, at least for the moment.

Light rain and snow to taper off overnight

Remnants of the winter storm that buried the Denver area Thursday night into Friday night are headed toward D.C. The storm, however, is a weaker version of its original self. That combined with recent mild temperatures means much of the precipitation we see will be on the light side and in the form of rain to start. Rain changes to snow north and west of the District, with light accumulations possible, mainly on grassy areas.

Forecast: Light rain late today transitions to snow or snow and rain mix into Sunday

With only around 1-2” of snow accumulation on the winter in most local spots, snow lovers are surely hungry for more. This forecast may tease more than fully satiate those needs. But, let’s look at the plus side here: minimized travel impacts on Super Bowl Sunday and still a good chance to see flakes flying. It might not be enough for snow angels, but in this winter we take what we can get!

Update: accumulating snow chances low Sunday except well west and northwest of D.C.

A quick glance at the evening model data indicates no big changes are required for Saturday night and Sunday when some wintry precipitation may move into the region.

PM Update: Satisfactory Saturday, but rain and snow at night into Sunday

Today marked the 12th straight day with above average temperatures and we’ll add another Saturday. But late Saturday, low pressure approaches from the southwest, initially bringing light rain. And by early Sunday morning, that light rain may mix with and change to snow. Sunday - for a change - looks wintry, with morning snow (or rain/snow mix south) and chilly temperatures.

What does 1.7” of snow through January buy Washington D.C. for the whole winter season?

Only about 15 percent of all winters in D.C. have recorded as little or less snow than we’ve seen this year. We’re now running almost 7” below normal season to date and it’s leaving some wondering what our chances are to break even. A look at past occurrences and the historical record might offer a few clues.

Super Bowl Sunday snow: it’s possible, but probably not consequential

We’ve been watching for several days now the potential for wintry precipitation this weekend. The responsible storm system is on its way to breaking a single storm snowfall record for February around Denver (9” already) but will weaken by the time it reaches the mid-Atlantic. Not to mention, there will be much less cold air to work with.

Deadly cold snap grips Europe, snow strands thousands in Serbia, Bosnia

Europe is currently in the grips of its worst cold snap in at least six years. Arctic air has been spilling out of Siberia into Eastern Europe, bringing more than a foot of snow to Istanbul and temperatures as low as -30ºC (-22ºF) in several neighboring countries.

Forecast: Calm, mostly clear end to our week; wintry weather this weekend?

Today through tomorrow morning should remain fairly tranquil and sunny, before clouds begin to arrive Saturday afternoon or evening. Those clouds could produce some rain or snow showers late tomorrow night and into early Sunday. There’s even an outside chance of accumulation if things come together right. But temperatures are going to be marginal, and the precipitation cutoff sharp. Our higher forecast confidence doesn’t return until Monday and Tuesday, when calmer and mild conditions -- in the upper 40s to mid-50s -- return as well.

PM Update: Groundhog says winter, mother nature says spring

After a gloomy start with clouds and showers, mother nature staged a rally with mild sunshine this afternoon. Temperatures soared into the upper 50s as if to defy Punxsutawney Phil‘s forecast for 6 more weeks of winter. The work week closes out with another warmer than average day, but we do have to start paying attention to a (small) chance of snow Saturday night.

Big snowstorm targets Denver and central Plains, could it reach Washington, D.C.?

A major winter storm is forecast to blast both Denver and Boulder, Colorado with 10 to 20 inches of snow through Friday. Over the weekend, the storm is forecast to weaken, but some of its remnant moisture may stream into the D.C. metro region. Enough cold air may be in place for the chance of a little snow Saturday night.

A Groundhog day pollen report: 6 more weeks of sneezing

Will we have 6 more weeks of winter, or 6 added weeks of allergy suffering? Bet on the latter. The U.S. Army Garrison (USAG) pollen report issued today for Washington, D.C. indicates both mold spores and tree pollen are well above average for the time of year.

Our gardens in a mild winter: the good, bad and beautiful

Let me say right off the bat, my garden does not look much different this year than any other year, except it isn’t buried under a snow drift! Why is that? Many of our plants evolved over the centuries to be more in tune with the dependable daylight hours than the more erratic temperature regime.

Groundhog Day 2012: Punxsutawney Phil sees shadow, 6 more weeks of winter

At 7:25 a.m. this morning, amidst mostly cloudy skies, and temperatures in the low 30s, Groundhog Phil saw his shadow in the little town of Punxsutawney, Pa. According to folklore, Phil’s sighting of his own shadow means there will be six more weeks of winter.

Forecast: Showers end early giving nice Groundhog day ending; weekend more-or-less dry

My bet is that the groundhog Phil will not see his shadow this morning. If that means winter is over, we better crank up the AC based on the kind of winter we have had. The next few days will continue the trend of warmer than normal winter weather but nothing quite like the last two spring days. There is a slight chance that light rain could visit on Sunday but you will be inside prepping for the Super Bowl, right?

PM Update: After Wednesday’s big warmth, back to reality... sort of

There was no record heat locally today, but we still saw plenty of springlike upper 60s and lower 70s! National Airport topped out at around 72 degrees before 2 p.m., and D.C. spent much of the afternoon right around 70 despite passing clouds. That’s more than 25 degrees above the normal afternoon high for February 1! Hope you had some time to enjoy it -- temperatures are headed back down, though still above average on the whole.

When will the Virginia earthquake aftershocks end?

On Tuesday, a 3.1 magnitude aftershock centered 40 miles northwest of Richmond rattled central Virginia. The tremor could be felt as close by as the Districts west and southwest suburbs. Since the August 28 5.8 magnitude earthquake, there have been almost 50 aftershocks of at least magnitude 2.0 in central Va, begging the question: when will they end?

January 1950 was a shocking 12 degrees warmer than average in Washington, DC with 14 days above 60 degrees, including 6 above 70. By comparison, our very mild January 2012 was a mere 5 degrees above normal. What made January 1950 so warm?

Very mild, dry January concludes, but month falls outside 15 warmest

The winter of 2011-2012 has taken on a completely different character compared to the previous few winters which started off cold. After the 6th warmest December on record (tie), January 2012 concluded with an average temperature 4.8 degrees warmer than normal (1981-2000 normal), the 17th warmest on record (tied with 1876).

Forecast: Warm-weather repeat today. Anything wintry for weekend?

Don’t get me wrong, I love myself a good blizzard. But personally I’m psyched for a second straight midwinter day in the 60s. After today’s warmth, which may come with a shower or sprinkle, we’re gradually colder into the weekend, and possibly cold enough for a wintry mix this weekend if the right circumstances come together.
