THURSDAY: WEATHER ALERT
Partly to mostly cloudy; PM rain, storms likely
Highs: 85-90
Winds: Southwest to North 5-10 mph
Rain and storm chances return Thursday, so you will want to have the umbrella on hand. Most will stay dry through the morning, with scattered showers and storms developing during the afternoon. The Storm Prediction Center has a Level 2 out of 5 ‘Slight’ risk category for severe storms along and east of the I-95 corridor. Damaging wind gusts are the highest risk in storms Thursday. There is also a low-end chance for hail and an even lower chance for a weak tornado. Heavy rain could also lead to localized flooding. Outside of wet and stormy weather, plan for hot and humid weather before the storms arrive, with highs nearing 90 degrees in D.C. and feels-like temperatures peaking in the lower to mid-90s.

THURSDAY NIGHT:
Rain, storms ending
Patchy Fog
Lows: 62-68
Winds: North 5 mph
Severe weather chances decrease after 8 p.m., with areas of patchy fog developing. If traveling, use caution with wet pavement and reduced visibility. Humidity levels will slowly fall during the overnight hours with cooler temperatures in the 60s expected.

FRIDAY:
Mostly to partly cloudy; isolated shower
Highs: 78-83
Winds: Northeast 5-10 mph
We’ll round out the week with cooler afternoon high temperatures in the lower 80s across the D.C. Metro area. Highs will only reach the upper 70s in the mountains. While a highly isolated shower or storm is possible, many will stay dry during the daylight hours. If you’re heading out for Friday night plans, have the umbrella, as rain chances will increase after 9 p.m.

SATURDAY:
Cloudy, humid; tracking rain, storms
Highs: 79-83
Winds: Southeast 5-10 mph
Rain starts Saturday morning with clouds and high humidity. Overall, it will be a rather grey day with scattered showers and a few rumbles of thunder possible during the afternoon and evening hours. Below-average afternoon highs, on either side of 80-degrees, are expected. If there are a few peeks of PM sun, it may feel hotter with the high humidity.

SUNDAY:
Partly Cloudy
Highs: 82-86
Winds: SW to West 5-10 mph
Sunday is trending drier and sunnier compared to Saturday. It will be humid in the morning, but humidity levels will slowly fall later in the day, as a cold front sweeps through the area. Most will stay dry; however, a highly isolated shower or storm can’t be ruled out, as the drier airmass settles in. Afternoon high temperatures will be in the middle 80s, which is seasonable for late August.
