Today: Mostly cloudy. 50% chance of p.m. showers. Mid-60s. | Tonight: Chance of showers. Upper 50s. | Tomorrow: Occasional showers (60-70% chance). Near 70. | Sunday: Sunny. 60s. | A Look Ahead | Get Express Forecast by E-mail


Another weekend is upon us and, as luck would have it, rain chances are returning. But it doesn't look to be nearly as soggy or chilly as what we saw a week ago. And if we can get through mostly cloudy and sometimes showery weather today through Saturday night, then mostly splendid conditions arrive just in time for Sunday morning's Marine Corps Marathon.

Today (Friday): Maybe some morning peeks of sun. Otherwise, a slowly approaching cold front means mostly cloudy skies, but probably no rain through midday. The clouds, combined with an onshore breeze from the east/northeast, should limit highs to the mid-60s. As clouds thicken, showers are possible during the afternoon into evening but are not a sure thing for everyone -- about a 50% chance. Confidence: Medium

Tonight: Shower chances remain at around 50% through the night, so you may want to take that umbrella just in case. Breezes pick up from the south overnight with lows mostly in the upper 50s. Confidence: Medium

Keep reading for the forecast through the weekend into early next week...

Tomorrow (Saturday): Doesn't look like the steady soaking rain we saw this past Saturday. But occasional showers are possible (60-70% chance) and maybe a thunderstorm, especially during the afternoon into evening, under mostly cloudy skies. As the cold front closes in from the west, 10-20 mph winds from the south out ahead of the front keep us fairly mild -- highs around 70. Confidence: Medium

Tomorrow Night: The details depend on exactly when the cold front passes through. For now, though, it looks like a mostly cloudy evening with a continued chance of showers, then clearing skies overnight. Lows near the low 50s downtown, but possibly upper 40s in the suburbs. Confidence: Medium

Sunday: Much improved! Sunny skies, a light breeze from the northwest and highs in the 60s -- not terribly cold behind the cold front. Low 50s should be cool but comfortable for the 8 a.m. start of the Marine Corps Marathon. Confidence: Medium-High


The weekend is likely to finish mostly clear Sunday night with temperatures dipping down to lows in the 40s. Confidence: Medium-High

We should hang on to partly to mostly sunny skies Monday with highs possibly making the mid-60s to near 70. Not bad, eh!? Confidence: Medium

Monday night and Tuesday we'll have to watch what happens with a cold front that may approach from the west and a coastal storm that could get organized and come at us from the south. Confidence: Low

UVA football a wash out, or could it be dry in the C-Ville tomorrow at noon?

Really, ennepe68?? I could have sworn many spots outside of the Beltway have reported frost during a couple mornings recently. But a lot of us (like me, downtown) live in warm spots! :)

"Much-needed rain" still seems to be on their nasty little weekend kick. They are even throwing in some slightly-out-of-season thunder for tomorrow.

My big gripe seems to be with Metro rather than the weather. Last weekend there was little going on, but they had no track maintenance scheduled. This weekend they ought to have none--so I look at the website--and find track maintenance on both the Red and Orange Lines!


Honestly, there are times when I suspect that the PR "right hand" of Metro doesn't know what the system maintenance "left hand" is doing! Doing track maintenance at the same time you are promoting the Marine Corps Marathon strikes me as sort of being at cross-purposes with oneself. This weekend, if any weekend, ought to be one that's free of any track-maintenance delays/closings.

At least, the weather is clearing up for the Marathon--even if Metro has system delays!

Pray, what does a Metro gripe have to do with the weather? But to provide some (I hope) help:

For one thing, there is no track work on the Blue or Yellow Lines, which service the race start at the Pentagon (and Pentagon City). Many runners/spectators will have already accounted for this and will park at Franconia-Springfield, Largo, or Huntington stations, for example, or will make arrangements to be dropped off at any Blue or Yellow Line station.

The early open for Metro is traditionally meant to accommodate the thousands of runners and spectators. If I were in the PR department and I knew that track work could add 30 minutes to a trip, and if I figured that this traditional two-hours-early open would also help offset that possible delay and still allow runners and spectators to arrive in plenty of time, I would definitely plug the good-golly out of my opening time precisely because I knew the track work was taking place.
