day's weather, on a scale of 0 to 10.


Some clouds spoil perfection, but 70s and partly sunny are sublime.

Today: Mix of sun and clouds, pleasant. 72-77. | Tonight: Partly cloudy, not too cool. 50s. | Tomorrow: Mostly cloudy. 40% chance of p.m. showers. Low-to-mid 70s. | A Look Ahead | Get Express Forecast by E-mail


Whatever we did to get these beautiful weekends we've been having, let's not change anything. Another gem concludes today with nearly ideal fall weather. We'll see a bit more in the way of clouds today but stay dry. With highs in the 70s, I'll take a few clouds if I have to. As we move into the work week, flow from the south ahead of a rather potent low-pressure system keeps us nice and warm, but with partly to mostly cloudy skies and sporadic rain chances at least until after a cold front comes through late Wednesday.

Today (Sunday): Today gets a guarded "Nice Day" declaration as we could see some clouds from time to time. Still, for late October, highs in the mid-70s with a good deal of sun is plenty nice. Winds blow from the south at 5-10 mph. Confidence: Medium-High

Tonight: We'll begin our respite from the chilly overnights that we've had recently. Evening temperatures are comfortable, falling through the 60s. Overnight, lows in the 50s are mild-ish as skies remain partly cloudy with light winds from the south. Confidence: High

Keep reading for the forecast into the work week...

Tomorrow (Monday): As skies become mostly cloudy, the bright spot is that any rain should hold off until later in the afternoon, when we'll see a 40% chance for some light showers. Even with the clouds, we should make the low-to-mid 70s in most locales. Winds continue from the south around 5-10 mph, increasing our humidity to somewhat noticeable levels. Confidence: Medium

Tomorrow Night: Shower chances stay in the forecast at around 40%. Expect any showers to be scattered and on the light side. With mostly cloudy skies, overnight lows only drop to the upper 50s to low 60s. Confidence: Medium


A warm front pushes well north of us Tuesday leaving us partly sunny, warm, and pretty humid for October. Highs at least to the mid-70s are accompanied by the chance of a few isolated showers or thunderstorms. Rather muggy conditions continue overnight with lows in the 60s. Confidence: Medium

Wednesday, if a cold front approaching from the west hangs back to the west (along the Appalachians) through morning and early afternoon, then we might see enough sun and strong enough breezes from the south to push highs to near or past 80. If it moves east a little more quickly, then increased clouds could hold highs to the mid-to-upper 70s. A line of showers and maybe thunderstorms is possible as the cold front sweeps through during the afternoon into evening. Confidence: Low-Medium

Though the cold front has moved past by Thursday, the cold air behind it runs a bit late, leaving us with a fairly pleasant day as skies clear and highs reach the 70s. A weak wave along the front to our south may throw a shower or two our way late. Confidence: Low-Medium

I'm running the Marine Corp Marathon next Sunday. What does the long-range forecast show for race time? Obviously I understand it could change over the next wee, but I'm really hoping for no rain!

Wonder why the Wash Post's weather page shows 2109 DCA cooling degree days for CY10, while the NWS site says 2110. Is there a rounding disagreement?

Yeah, I know it's small potatoes, but the discrepancy has been showing up for at least the last few days.

Centreville VA the clouds are starting to fill in now, but gosh what a nice late October weekend!

Rather skeptical about tomorrow's much-unneeded rain; there seem to be no significant synoptic features around, and we're squarely in the warm sector.

Wednesday looks better for precipitation, with the cold front coming through. Should be a sudden quick shower or thundershower...the front may hang offshore until some time Thursday. The analog mentioned for the Upper Midwest storm seems to be the 1940 Armistice Day blizzard though I doubt that there will be that sharp a temperature drop in western Wisconsin.

Low confidence this far out, but I'd ballpark race-time (8 a.m.) temps in the mid-40s to low 50s with afternoon highs in the 60s to near 70. Rain chances look on the low side for now, but that can change. -Dan, CWG

Early outlook for Saturday? High pressure provides a pleasant day with highs in the 60s (Confidence: Low-Medium). -Dan, CWG
