Today's Daily Digit
A somewhat subjective rating of the day's weather, on a scale of 0 to 10.
7A brisk breeze takes the digit down a few. Still, a nice day away from the shade.

This is a tough time of year for wardrobe consistency. In typical spring fashion, the wardrobe should get a good workout as we shift from cool and breezy today, to warmer and sunny Thursday and Friday, to very warm (some might say hot) and even a little humid over the weekend. So, we go from jackets and long pants today, to shorts and sandals Saturday and Sunday. Overall, it's a pretty good forecast if you have outdoor plans, though we'll have to see if any thunderstorms pop up this weekend.

Today (Wednesday): After a cool start, mostly in the upper 30s to low 40s, morning temperatures recover into the 50s. But a brisk 15-20 mph breeze from the west/northwest, with some gusts around 30 mph, keeps the air feeling rather cool throughout the day. Afternoon highs only reach the low-to-mid 60s despite mostly sunny skies. Confidence: Medium-High

Tonight: Like last evening, temperatures quickly drop into and then through the coolish 50s. Skies stay mostly clear through the night as winds slacken to around 10 mph or less from the west/northwest. Lows ranging from the upper 30s to near 40 in the suburbs to the low-to-mid 40s downtown should be several degrees below average, but a little warmer than last night. Confidence: Medium-High

Keep reading for the forecast through the weekend....

Tomorrow (Thursday): It's another cool beginning. But this time the mercury rises more efficiently with temperatures into the 60s by lunchtime. A full day of sun should lift afternoon highs to the low 70s with a consistent 10-15 mph breeze from the west. Confidence: High

Tomorrow Night: We'll be noticeably milder than tonight with evening temperatures mainly in the 60s, dipping into the upper 50s by late evening. Overnight lows bottom in the upper 40s (suburbs) to low-to-mid 50s downtown with partly cloudy skies. Confidence: Medium-High


Get you work done early Friday morning. Because by late moring, temperatures should already be nearing or surpassing 70, beckoning you to come outside. It only gets better in the afternoon with highs near 80 or in the low 80s, thanks to partly to mostly sunny skies and a warm flow from the southwest. We stay mild Friday night with lows from the upper 50s in the cooler suburbs to the low-to-mid 60s downtown. Confidence: Medium-High

Summer weather kicks into high gear for this first weekend of May, complete with a touch of humidity. Highs make a run at the upper 80s to low 90s with Saturday night lows in the upper 60s to low 70s. I wouldn't go changing any plans at this point, but the heat and a bit of humidity could touch off an isolated shower or thunderstorm Saturday afternoon or evening (20% chance), with a little better chance (30%) of isolated to scattered showers and storms Sunday afternoon or evening as a cool front approaches. Confidence: Medium

FIREDRAGON47 - glad to have your report. Did anyone out there see frost?? I'm curious, but also skeptical.. downtown's coldest was about 42 degrees.

BWI got to 34, I'm usually a tad cooler but I didn't see any frost this morning either.

Tom Kierin on Channel 4 is calling for a Saturday high of 83 and Sunday high of 80. Why the huge discrepancy between his forecast and what the NWS is showing for Sat/Sun? I'm thinking about going to the Maryland Sheep and Wool Festival this weekend and 80 sounds a lot nicer than 90 for tromping around outside.

Unless an approaching cool front speeds up, it seems to me the overall warmth of the air mass combined with a warm flow from the south/southwest could have us flirting with 90 both Saturday and Sunday. -Dan, CWG

It was 32.7F this morning at 1900ft east of Front Royal. I did not observe any frost... I believe I have good air drainage...

No UnitedCast? Why does the CWG hate the US Open?

I'll just have to guess from the info provided here, as to the game time temperature, and where my Benny Olsen Jersey.

I did not see any frost. Then again, I was not up that early and live in the city.. ;-)

Thanks for alerting us... tonight's game went under our radar, so to speak. UnitedCast is now posted directly below this post on the main page. Bundle up if you're headed to RFK.

All more frost allowed. I am potting annuals this weekend! Thanks guys...I hope I can remain sock-free from this weekend until October.

Posted by: dstu | April 28, 2010 11:46 AM | Report abuse

Some areas might have a frost threat tonight. From then on I think we're frost-free until after hurricane season.

Still uncertain if we'll hit ninety this weekend...I'd say 85 or 87 is a good bet.

Ya'll are playing with fire (ice, really)...dont do my planting until Mothers Day around here. 36 just SW of IAD today - no frost.

Temps are not going anywhere fast today, may be tough to hit 60 at this rate.

The clouds that have now moved in aren't helping matters. Upper-air temps had indicated that near 60 might be the best we could do today. A full day of sun, even with the breeze, might have been enough to overcome at the surface and get us into the low-to-mid 60s. But may not get there now that skies have clouded up. -Dan, CWG

I did see light frost on the north slope of the horse farm on the next ridge over from me. But the official low temp at Martinsburg/Shepherdstown was 38.

I'll take the upper-50s, areas in Northern NY and VT are reporting 2 feet of snow!
