Washington starts Thursday with a mid-level cloud deck along and east of Interstate 95 during the morning, but the easy morning gives way to a few shower and thunderstorm chances by afternoon. Temperatures are expected to climb to around 89 degrees before the District gets a cooler, drier reset for Friday and Saturday.

Storm Chances Build Thursday Afternoon

Thursday morning should see a mid-level cloud deck along and east of Interstate 95, with isolated showers through daybreak mainly in western Maryland. The better chance for showers and thunderstorms arrives from roughly 3 p.m. through the evening, when a few storms could bring brief downpours and spotty gusty winds, according to the National Weather Service.

Storms are expected to trend east toward the Interstate 95 corridor, with a window between about 4 p.m. and 9 p.m. That update changes the planning equation for afternoon commutes, outdoor dining and evening events; the severe-weather threat remains limited, but an indoor backup is still a smart idea.

Friday Brings A Noticeable Cooldown

Showers and thunderstorms should diminish a couple of hours after dark Thursday, with the cold front crossing late Thursday night into early Friday, followed by partly cloudy skies and a low near 72 degrees. Friday then brings highs ranging from the upper 70s to mid-80s, with possible residual afternoon showers and thunderstorms. Northerly winds could gust to 15 to 20 knots in the afternoon.

Saturday looks like the weekend's best outdoor-weather bet, with mostly cloudy skies, lower humidity and highs in the 70s to low 80s. The forecast stays mainly dry, although Saturday night may turn mostly cloudy with temperatures dipping to around 67.

Sunday Starts The Next Unsettled Stretch

Weather becomes less cooperative Sunday, with renewed chances of showers and thunderstorms.

Unsettled weather may continue into next week. The forecast does not specify the District's current watch, warning or advisory status, but it favors keeping an eye on the sky beyond Saturday.
