Full Weather Report

Last updated on September 21, 2021 at 4:18 p.m.

Tuesday is the last full day of summer. We could see a few showers late, especially west of D.C. — but most of the region will be staying dry. Overnight temperatures will fall into the 60s to low 70s, a little warmer than previous nights.

A few showers are possible tomorrow morning, but coverage and intensity will increase through Wednesday. Temperatures tomorrow will top out in the mid to upper 70s with the extra cloud cover. It will be a little muggy and a little breezy at times. By Wednesday night, we could even have a few thunderstorms.

We will keep chances of rain Wednesday overnight into Thursday. We will also have to watch for some flooding Wednesday night into Thursday morning across the region due to heavy rain.

On Thursday, temperatures only climb into the low 70s. Expect plenty of cloud cover Thursday but much cooler conditions. Most of the rain should exit the region with a cold front by Friday morning, although some rain could get held up, especially south of the D.C. area. We will continue to watch that front moving through the region, otherwise expect a return to sunshine Friday with more fall-like temperatures in the upper 60s and lower 70s. We stay in the mid 70s for this upcoming weekend with plenty of sunshine.

TUESDAY EVENING: Mostly cloudy. A few spotty showers, mostly west of DC. Otherwise warm and muggy. Temperatures in the 70s.

TUESDAY NIGHT: Mostly cloudy. Showers, mostly west of DC. Mild and muggy. Lows: mid 60s to low 70s.

WEDNESDAY: Cloudy. Seasonably warm but unseasonably very humid. Spotty showers during the day becoming more numerous with some thunderstorms later toward evening. Becoming breezy. Highs in the mid 70s to low 80s.

THURSDAY: Periods of rain, heavy at times with a few occasional thunderstorms, all ending during the evening. Breezy, mild and muggy early then becoming much less humid toward night. Highs in the low to mid 70s.

FRIDAY: Cool and dry start. Mostly sunny. Mild and pleasant the rest of the day. Highs in the mid 70s.
