* Flash flood watch until 11 p.m. for areas west and southwest of D.C., not including the city *

2:20 p.m. update – Flash flood watch extended east

The flash flood watch that runs through 11 p.m. has been expanded into the immediate area. It now includes Fairfax, Loudoun, Prince William and surrounding counties south and west of the area. D.C. remains just outside of this flash flood watch, but we will continue to monitor progression of slow-moving storms now pushing through western parts of the area.


12:45 p.m. update – Storminess increasing to our west

Showers and thunderstorms have increased in coverage and intensity this afternoon, largely just to our west. These are so slow moving it is hard to say how far east they make it before raining themselves out, or new storms developing, but they are slowly headed our general direction. For now, a new flash flood watch is mostly focusing to our west and southwest. Do keep an eye and ear out on this activity as we head through the afternoon. Torrential rain and some flooding is possible with any shower or storm.

From 6:00 a.m…

A somewhat subjective rating of the day’s weather, on a scale of 0 to 10.

7/10: It’s certainly no perfect 10, but for mid-August, mid-80s and only a few showers or storms around isn’t all that bad.


Today: Partly to mostly cloudy, a few showers and storms. Highs: Mid-80s.
Tonight: Scattered showers and storms. Lows: Low-to-mid 70s.
Tomorrow: Scattered showers and storms. Highs: Low-to-mid 80s.

Partly to mostly cloudy, humid and chance of showers and storms. Sound familiar? It should, and it’s going to continue for a few more days, thanks to a lingering upper-level system and a humid air mass. We’ll get a break midweek as high pressure makes a brief appearance, before late-week shower chances likely rise again.

Today (Sunday): It’s still quite sticky out there, even as winds come from the north-northeast behind a front dropping to our south. Plenty of clouds are interspersed with occasional breaks of enough sun to send highs into the mid-80s. A few afternoon showers and storms are possible, although like yesterday a good portion of the area could stay dry. Confidence: Medium-High

Tonight: Showers and storms may remain few and far between during the evening, with the potential for more numerous and heavier showers and storms after midnight. With light winds from the north-northeast, we’ll probably see some fog or mist at times, with lows in the low-to-mid 70s. Confidence: Medium

Tomorrow (Monday): Monday has a chance at being more active than today, with a few rounds of scattered showers and storms possible throughout the day. Heavy rain and flooding is a risk with any storms that move through. Skies remain partly to mostly cloudy with highs reaching the low-to-mid 80s. Surely not the nicest start to the workweek we’ve had. Confidence: Medium

Tomorrow night: Shower and storm chances remain elevated into the evening with plenty of energy still overhead, before activity may tend to wane overnight. It’s not quite as humid, so fog or mist are not as much of a concern, but skies remain fairly overcast. Expect overnight lows in the upper 60s to low 70s. Confidence: Medium

This upper-level disturbance finally shows signs of moving out on Tuesday, but not before one more day with a decent chance of some scattered showers and storms. The atmosphere shouldn’t be quite as juiced, so the heavy rain and flood threat is a bit lower. Partly sunny skies are on tap, as are highs rising into the mid-to-upper 80s. Shower chances diminish Tuesday night, with lows from the mid-60s to near 70. Confidence: Medium

High pressure moves in on Wednesday and we get a rare day with little or no chance of rain, although you’ll still notice the humidity. Partly to mostly sunny skies give temperatures a boost, as highs head for the upper 80s to low 90s. Confidence: Medium
