FORECAST IN DETAIL
By David Streit, CWG Meteorologist
Up, up and away! That's the direction temperatures are heading as the week progresses. Temperatures 10 degrees below average today will transition to 10 degrees above average by the weekend. Now that's a warming trend. While temperatures experience a steady rise, the dense cloud cover abruptly dissipates -- departing this morning, with abundant sunshine for the next several afternoons.
Today (Tuesday): Early morning clouds quickly dissipate, and plentiful sunshine returns. Winds from the northwest at 10-15 mph will bring in some cooler than average air, with highs just 60-65. Confidence: Medium-High
Tonight: This will be a heavy jacket evening. Brisk winds from the northwest coupled with temperatures dropping quickly through the 50s to the upper 40s will have the heated indoors beckoning. Lows drop into the upper 30s and lower 40s nearly threatening records. Confidence: Medium-High
Keep reading for the forecast through the weekend...
Tomorrow (Wednesday): Sunshine should rule the day, although pop-up puffy clouds are possible mid-afternoon. Highs will be in the mid-to-upper 60s. Brisk winds can be expected to make jackets a desirable part of outdoor attire as they race along at 10-20 mph. Confidence: Medium-High
Tomorrow Night: Temperatures won't drop off quite as quickly this evening but it still won't be outdoor café weather as readings fall through the 50s. Another improvement comes as winds quickly drop off to just 5-10 mph. Confidence: Medium-High
Thursday should be as close to perfect as one could ask. Highs climb to the low-to-mid 70s under spotlessly sunny skies. Barely a hint of breeze makes this a day to get outdoors. Confidence: Medium
Friday morning jackets will be but a memory by noon as temperatures rocket from the 40s to the 60s and peak in the mid-to-upper 70s by afternoon. Winds remain light all day long under sunny skies. Confidence: Medium
The weekend is looking like summertime. Morning lows in the upper 50 to lower 60s are a welcome change and highs well into the 80s should lead to shorts and flip-flops in the park. Given enough sunshine, Saturday may hit 90 in a few spots--though the possibility of increasing cloud cover in the afternoon may hamper that. A thundershower is possible by late Sunday but chances are still only 20% for now. Confidence: Low-Medium

The breeze out there has a bite, but otherwise it's quite glorious this morning in Fairfax. Lots of sun. It sure feels like it's going to be warmer than low-60s come the afternoon, if this sunshine holds.

Clouds departed in a hurry, didn't they? Forecast updated to reflect this.
@stacylane
You may be right that we do better than low 60s today given where temps are now and all the sun. However, we do have northwest winds blowing in some cool air.

CWG, I am so ready to plant my tomatoes & basil outside. But our overnight temps just aren't high enough.....yet.
I know forecasting days & days in advance is pretty darned iffy, but looking into the first week of May do you see any likelihood of more "heavy jacket evenings" for Fairfax county?
If not then I will probably plant this weekend.

FIREDRAGON47 - I say: plant away. Next week looks ok. And it is a combination of long-range weather forecast + seasonal climatology that makes me believe you should have warmer (soil) temperatures by then!

I believe that after tonight much of our area frost threat is over until October.
There could still be a May freeze or two in the West Virginia mountains and possibly the Blue Ridge.

Noooo! I'm doing a 30-mile hike on Saturday (along with 300 other people--it's the Sierra Club One-Day Hike) and was really, really hoping it would remain unseasonably cool. Near 90 is going to be killer. Any chance for low humidity, at least?
