3:00 p.m. — Flash flood watch issued into Thursday morning due to additional heavy rain predicted

So far today, 0.5 to 0.75 inches of rain has already fallen and the heaviest may be yet to come later today into tomorrow. The National Weather Service has issued a flash flood watch in anticipation of another 1 to 3 inches of rain through Thursday morning.

“Several rounds of moderate to heavy rainfall, with a few embedded thunderstorms possible, are expected to persist through Thursday morning” the Weather Service writes, calling for storm totals of 2 to 4 inches. “This could result in localized instances of flash flooding.”

8:10 a.m. — Rain has already overspread the DMV area from southwest to northeast, with much more to come today into tomorrow. See full forecast below.

Today (Wednesday): Temperatures start the morning in mild territory, in the mid- to upper 60s, with showers moving in from the southwest and west between 9 and 11 a.m. Rain is likely during much of the afternoon, and it could be heavy at times with a rumble of thunder possible. Highs top out near 70 under overcast skies. Confidence: Medium-High

Tomorrow (Thursday): Rain continues through the morning hours with minor flooding possible, but should move from northwest to southeast during the afternoon, even as skies continue to be mostly cloudy. Morning temperatures in the 60s fall back into the 50s during the afternoon as a cooler breeze picks up from the northwest. Rain totals of 1 to 3 inches seem like a good bet, and could end up more like 2 to 4 inches if heavier bands of rain persist. Confidence: Medium

Tomorrow night: Can’t rule out a few lingering showers during the evening and overnight. Otherwise we’re mostly cloudy with cooler lows in the mid-40s to near 50. Confidence: Medium

A look ahead

Friday sees mostly cloudy morning skies with the chance of a shower, turning partly sunny in the afternoon with highs in the low to mid-60s and light winds. Mostly clear Friday night with much cooler lows (but closer to average for mid-November) dipping to the upper 30s to low 40s. Confidence: Medium-High

The weekend starts with high pressure overhead, which means a sunny but cool Saturday with light winds and highs in the mid-50s, followed by Saturday night lows in the 40s. Sunday is still a bit of a question mark as model forecasts range from dry to scattered showers (not enough consensus to lean in either direction yet), with highs aiming for the low to mid-60s. Confidence: Medium
