Forecast: A splendid first weekend of spring

Spring officially arrives today at 1:32 p.m. and what a day and what a weekend to welcome it. For the fifteenth straight day, temperatures will be above average -- but unlike last Saturday when we were socked in with clouds and rain, today we'll bask in sunshine. Though sunshine will be less dominant tomorrow, we're still looking at much-above-average warmth with temperatures again surpassing 70. Rain is likely Monday, but that's a small price to pay for this glorious weekend.

PM Update: Spring arriving to warm temperatures

We wind down the work week on a spectacular note as highs reach the lower 70s across most of the area. It lasts through the weekend -- the first official one of spring -- when highs will have little trouble getting to and past 70!

Great weather!... hard choice for hoops fans

With sunshine forecast through much of the weekend, and highs near and into the 70s, this perfect to near-perfect weather feels even sweeter after the cold and snowy winter we've had. Yet it coincides with all the madness that comes with the early rounds of the NCAA Tournament. What's a sport's lover to do?

Forecast: Spring fever still going strong

The only crimp in this amazing streak of weather is the pollen, which is approaching high levels. But even as a seasonal allergy sufferer, I have to relish in this otherwise PERFECT weather.

PM Update: Glorious conditions continue

Though we're still about 48 hours off the start of spring, on days like today it's easy to feel like we're well into the new season. Highs topped out right around 70 today and will again Friday and into the weekend!

Forecast: Spring warmth arrives two days early

What a string of beautiful days to build up to the official arrival of spring this Saturday! The only question is whether it will last through Sunday. I am betting it can. Many of the computer models are starting to slow down the progress of a major cold front so that Sunday should still be salvaged, although not without some increasing winds and clouds. Monday will remind us that spring is in its infancy with a much cooler and blustery day.

PM Update: About as good as March gets

Talk about near-perfect -- highs in the mid-and-upper 60s feel pretty awesome! On top of that, we're looking at several legitimate chances to hit 70 degrees or higher over the next few days.

Winter's abrupt end

After crushing us December through February, winter has gone away with barely a whimper this March. So far this month, we've reached 50 or better every day except March 2, 3 and 4 -- that's 13 out of 16 days. Recall we hit 50 just once the entire month of February. Last March was much fiercer by comparison, when we only made it to 50 or higher on 6 out of the first 16 days, with a streak of 5 consecutive days in the 40s March 12-16.

Forecast: Several days of spectacular weather

It's been a long, snowy and consistently cold winter. So who can blame us for being downright giddy about the forecast over the next several days, which features abundant sun and the chance to reach 70 for the first time since Nov. 16 (at Reagan National Airport).

The death of a snowpack

Snowpack is defined as layers of snow that accumulate on the ground from multiple snowfalls. We had four accumulating snowfalls during late January and early February that created a snowpack of two feet or more across much the Washington area. BWI recorded a snow depth of 34" on February 11 and Dulles Airport recorded a snow depth of 26" on February 10. Our area's snow depth rivaled, and in some cases surpassed, the snowpack from the historic winter of February 1899. At my house near Oakton, VA, the snowpack peaked close to 28".

Daylight Saving changes time, not weather

On early Sunday morning, most of the United States, save Hawaii and most of Arizona, sprung an hour ahead to Daylight Saving Time (DST), losing an hour of sleep in the process. However, when it came to weather observations and forecasting, the National Weather Service did not change its clocks this past weekend. Nor will it do so in November.

Forecast: The return of the sun....

Yes, when you look out the window this morning, you will probably question today's headline, but we just have to be patient a little bit longer. The wet drudgery of the last several days is coming to a close with skies actually starting to clear some this afternoon. The chances of significant sun soar tomorrow as our pesky system finally goes far away. Day time temperatures will return to normal and then above normal levels as this week progresses. And I'm keeping that chance for 70 degrees with sun on Saturday. Yeah, we earned it.

PM Update: Drying out, but clouds slow to depart

Just a bit of rain moved through midday, otherwise it has been another cloudy and cool one around here. Afternoon readings in the upper 40s and low 50s are about 5 degrees below the quickly rising average high temperature for the date.

Forecast: Cloudy, damp for another day

I imagine many of us are growing weary of this gray, depressing weather pattern and are ready for some sunshine. It's coming but we'll have to get through one more day of soupy, overcast conditions before the sun makes its return tomorrow. Then we're looking at an extended period of sunshine and warming temperatures right on through Saturday.

Forecast: Gray & damp, improvement by Tuesday

Rivers are on the rise today while showers, breezes, and overcast skies persist. Even tomorrow we'll have a tough time shedding the clouds and dampness. Can you hold out until Tuesday? We'll emerge back into a decent, sunny, streak of weather with temperatures closing in on 60. Oh! Did you turn clocks one-hour ahead last night? Daylight savings time starts today.
