D.C. area forecast: Shower or two may spoil a fine fall day
By Brian Jackson
Kind of an in-between sort of day today, with considerable clouds and the chance for a few light showers. We’ll see more in the way of sun tomorrow, but then probably cloud up as low pressure moves closer. It’s the same system that brought flooding rains to Texas yesterday, but should only produce occasional showers here as we get into Tuesday.

D.C. area forecast: Mostly nice this weekend, but potentially wetter into the week
By Ian Livingston
It’s getting harder and harder to argue the cool season isn’t here, or at least right around the corner. Today should feature temperatures a bit below the average high of 74 at National and Dulles, but that keeps readings right near the center of comfortable. Overall, the weekend is mostly a winner, and considerably better than what might be coming in the early work week, as rain gathers off to the south and eyes the area.

Antarctic sea ice reaches greatest extent so late in season, 2nd largest extent on record

PM Update: A few showers tonight; decent weekend shaping up
By Jason Samenow
The last in a series of three summery days is in the books, as we passed the 80-degree mark yet again. But 70s are in our future for quite a while behind a cool front sliding through the area this evening. Showers are possible, but mainly from D.C. south. The balance of the weekend is dry, although a few showers may return late Sunday.

Anvil crawler lightning over the Jefferson Memorial in Washington, D.C.
By Kevin Ambrose
Thunderstorms over the western suburbs of Washington were very slow to move eastward last night. For over an hour, they put on a light show across the western sky. Much of the lightning came in the form of anvil crawlers which branch (or crawl) across the sky near the thunderstorm’s anvil top like tentacles.

D.C. area forecast: Summery air dwindles, then exits; perfect autumnal days might be few
By A. Camden Walker
Summertime remains somewhat in control still, but it’s arguably more tolerable than recent. As we remain in close proximity to a cold front, showers and thundershowers are possible through much of today — highest odds perhaps to our south. Saturday is a gem, most likely! But, Sunday and into the workweek the “niceness” may be punctuated by chances of cloudiness with showers. Your umbrella could only get one full day off? Stay tuned!

PM Update: Showers and storms weakening; more possible on Friday
By Jason Samenow and Dan Stillman
For the second straight day, we’ve had a touch of summer, with highs reaching the low 80s and a little humidity. It’s remained dry, but a wave of low pressure moving in from the west promises scattered to widespread showers and storms into the overnight. The wave exits Friday, but we can’t totally rid ourselves of shower chances.

Gusty storms possible tonight in Washington, D.C. and Baltimore areas
By Jason Samenow
A summertime air mass has returned to the region and cold front lurks not far to the north. As the front slowly sinks south this evening and a little wave of low pressure rides along it, a cluster of thunderstorms may develop. The best chance of storms lies in D.C. northern suburbs up to around the Mason Dixon line.

D.C. area forecast: Showers possible next 4 days but plenty of dry intervals

My money is on the good rains to come later today followed by lighter and more scattered activity tomorrow. Saturday could still be salvaged as the bulk of the showers may slip to our south. I sure hope so for those outdoor weddings and so we can see the Harvest Moon that night.

By this past summer’s standards, this afternoon’s temperatures and humidity levels were a walk in the park. But when you compare these conditions to the dry, crisp air in recent days, it definitely felt muggy. It stays this way into tomorrow, and we throw in the chance of some showers as a cold front edges closer.

D.C. area forecast: Comfortable today, showers and 80s sneak attack tomorrow
By Matt Rogers
Our post-summer season is continuing to work out fairly nicely with high temperatures frequently in the comfortable 70s. Today is no exception, although clouds increase later today. We’ll hit a brief roadbump tomorrow as temperatures pop into the low-to-mid 80s. Some showers are possible tomorrow and that risk continues into Saturday as a cool front gets tangled up in our area. Sunday may finally break free with more sun.

The overwhelming majority of days this month have been sun-filled and fantastic. So let’s keep it going.

By Ian Livingston
We welcome fall today on a somewhat summery note. However, autumnal conditions won’t be too far behind the official start, as we ride a bit of a temperature roller coaster this weekend. The fairly sharp change in temperatures is ushered in by a cold front pushing through. Out ahead of that, we could see some gusty showers and thundershowers blow through later today. Then it’s pure glory once again.

The transition occurs late Saturday, when a cold front produces possible showers and thunderstorms.

All in all, a beautiful one around here, but those temperatures only topping out in the upper 60s and low 70s are more typical of the second week of October. An autumnal night is ahead, with slightly warmer temps showing up tomorrow.

D.C. area forecast: Feelin’ like fall today, then warmer before weekend cold front
By Dan Stillman
As we often see this time of year, there is a silver lining to stormy days like yesterday - the gorgeous stretches of fall weather that follow. Today through Friday is a perfect example with sunshine and pleasant daytime highs in the 70s to near 80. A cold front brings rain chances back at some point during the weekend.

D.C. area forecast: Windy and stormy today, much nicer tomorrow
By Matt Rogers
Mother Nature is turning on the spigots to keep September rains on track, and she is working very efficiently this time. Unfortunately, the rains may accompany severe storms this afternoon or early evening (stay tuned for updates). Although his muggy air mass is not welcome, we clear it out by late tonight to make for a much better day tomorrow. The balance of the week into the weekend is mostly dry and cool, but we may have some more showers Sunday.

We’re almost getting used to these highs in the 70s, which is a good thing as averages have now fallen to there. Thanks to plenty of clouds today, afternoon temperatures are running a few degrees below normal, but I doubt there are too many complaints! Clouds should continue to thicken heading into the evening, and showers are also approaching from the south and west.

By Brian Jackson
Clouds and rain are on the way, but we’ve got more than enough time to squeeze out another gem to close out the weekend. Even a good part of Monday may not be bad despite more clouds. A cold front (with low pressure developing along it) brings rain chances starting tomorrow afternoon, though the best odds for steadier, heavier rain should wait until Tuesday.

By Ian Livingston
Today and tomorrow are the last days with average highs 80 or above until May 31st for D.C. It’s prime “awesome day season” for sure. We’ll live up to that idea today, and most likely tomorrow. Afterwards, a strong cold front approaches as a storm system develops along it. That combo promises rain for the region. Happily, murkiness wants to focus on the workweek rather than the weekend. And for that, we can be doubly thankful while out enjoying the next two days.

The Nice Day campaign is in full swing. High pressure and its trusty surrogates (sunshine, light breezes, comfortable temperatures, and low humidity) are scoring record-high approval ratings based on the latest polling. There is a strong chance that each day this week could earn a Nice Day badge, creating quite a post-summer rally. The issues become more cloudy by the weekend as rain chances sneak back into the debate. However, the change would likely find support from the rainfall deficit reduction advocates, so everybody wins with this weather.

By Ian Livingston
Our summery conditions of late are about to be given the boot by a strong cold front. Unfortunately, that means strong to severe afternoon storms are a pretty good bet across much of the area. While this isn’t looking on par with the derecho in June, it has the potential to end up being more significant than many storm events around here. If you’re heading out, particularly this afternoon or evening, please do pay close attention to the weather. When thunder roars, head indoors. The good news is, it’s going to turn amazing once we’re behind the front.

A miserable week for weather forecasters in Washington, D.C.

We take pride in getting the forecast right most of the time. Occasionally, we’ll mess up a forecast on a given day and then recover. But this week, starting Monday - more or less - we’ve hit an extended slump.

Thunderstorms and low-hanging clouds in the Austrian Alps (PHOTOS)
By Justin Grieser
Weather enthusiasts would agree that there’s just no taking a break from staring at the sky – even when on vacation. That’s just what I did last month while traveling through France, Switzerland, and Austria for a family wedding.

Forecast: Still pretty tropical today with a few thundershowers
By David Streit
Relief from this heat is on the horizon, but, unfortunately, not until Sunday. Until then, the warmth will be impressive for this time of year, running nearly 10 degrees above normal. The tropical mugging we have suffered gradually weakens. While some thundershowers are possible today, the real fireworks are Saturday evening when a strong cold front barrels through. By Sunday and Monday...highs in the 70s...yum

PM Update: A few storms in southern suburbs; hot and still humid tomorrow
By Ian Livingston
Even though it felt like it might rain at any minute given all the moisture in the air, we’ve managed another day without more than a handful of spots getting doused. However, in the city and to the south and east, some heavy downpours and frequent lightning have occurred and remain possible this evening. Tomorrow’s another warm and humid day, with a slight chance of showers/storms.

By Jason Samenow
Tropical storm Leslie added 5 mph to its peak wind speed (up to 75 mph), becoming the 6th hurricane in the Atlantic in the 2012 season. It’s positioned 465 miles south-southeast of Bermuda and slowly headed in that direction. It may be in the island’s vicinity Saturday or Sunday.

D.C. area forecast: Still swampy with a risk of heavy soakers
By Dan Stillman
For those tired of this tropical air mass that’s taken up residence here in the D.C. area, there is light at the end of the tunnel - in the form of drier and cooler air next week. Until then, we’re stuck with moderate to high humidity, highs approaching and above 90, and a daily risk of showers and storms.

The focus for any showers or storms slides south and east of the area during the evening, but could see a pre-game or early-inning shower or thundershower before that happens.

PM Update: A few evening showers, better chance Wednesday, very humid
By Jason Samenow
The rains predicted from Isaac’s remnants have underperformed - for the most part - but the humidity has not. A thick, muggy air mass holds in place through tomorrow when we probably have our best chance of scattered showers and storms. This is due to an approaching cold front which will serve as a focus for all of this moisture.

Obama and Romney on climate change science
By Jason Samenow
With the race to the White House heating up, it raises the question: where do the presidential candidates stand on global warming? In short, Obama is a global warming “believer” but has provided little substance to back his conviction and seldom talks about it. Romney, on the other hand, presents a wavering, sometimes mocking assessment on the severity of the issue.

D.C. area forecast: High humidity with roving rains from Isaac’s remnants
By Matt Rogers
This very humid, late-summer, Isaac-enhanced air mass stuck over our area creates a complicated precipitation forecast. This particular air mass can trigger heavy showers and sometimes thunderstorms essentially at any time to drench your activity. And we are stuck in this soup until this weekend when a big cold front sweeps the area. So be prepared for more rain risks and sometimes heavy downpours.

D.C. area forecast: Bouts of heavy rain, possible flooding thru Wednesday from Isaac’s leftovers
By Jason Samenow
The deluge in the District and southern Maryland Sunday was just the beginning. Through the middle of the week, wave after wave of heavy rain is possible as Isaac’s remnants slowly trudge through the region. More instances of localized flooding are likely before we gradually dry out late week.

Lightning near Mt. Vernon Square in Washington, D.C. Saturday night
By Jason Samenow
The atmosphere was juiced Saturday night. Hot, humid air had pushed temperatures into the mid-90s during the afternoon, and the sultry air lingered deep into the evening. Meanwhile, storms began firing up along a stationary front sprawled over the region. They were loud and they were electric. Craig Hudson was ready with his camera to seize the moment.

It’s a warm and muggy one at the ballpark. Scattered showers and storms are likely across the D.C. area. Not a sure bet they’ll soak the stadium, but definitely have the rain gear handy.

D.C. area forecast: Meteorological fall starts toasty and humid, and an increasing rain risk lurks
By Ian Livingston
50 days of 90 degrees or higher, 28 of which were 95 or higher... it’s nice to finally put meteorological summer (Jun-Aug) behind us! Now we say another unofficial good-bye to summer this weekend, and while temperatures will “cool” thanks to more clouds and rain chances, there’s no major hint of fall in the forecast just yet. Today is maybe the pick of the next three for doing things outdoors, simply because rain chances are relatively low. It’s not going to be the most pleasant time during the day though.

Unless you’re a fan of baking in the sun, be glad this isn’t a midday game. Heat and humidity probably call for an extra beer (plus lots of water!). If there’s a t’shower, it’ll be isolated.
