The D.C. region is under another risk of strong to severe thunderstorms late Monday, with the potential for damaging wind gusts and localized flash flooding.
The National Weather Service issued a flash flood warning for the majority of the D.C. region, including the District, Montgomery and Prince George’s counties in Maryland and parts of northern Virginia, until 1:45 a.m. Tuesday. The parts of the area were under a flash flood watch or a severe thunderstorm warning hours prior to the warning.
A series of cold fronts will influence weather in the Mid-Atlantic early this week, bringing a risk of scattered showers and thunderstorms from Monday morning into the early hours of Tuesday. Though forecasters say some storms are possible along Interstate 95 on Monday morning, the most significant potential for severe weather will be Monday evening and Monday night.
Commuters should expect inclement weather between 6 p.m. and 10 p.m. starting along Interstate 81 and building eastward toward the D.C. and Baltimore metro areas after dusk, with rumbles of thunder lingering until around midnight.

“Most of our rain chances for the week ahead come inside of a small window of opportunity later Monday,” NBC Storm Team4 meteorologist Chuck Bell told WTOP. “All is quiet through at least early to mid afternoon, as clouds begin to build ahead of a cold front.”
Storms are expected to form in clusters as a cold front moves southeastward from the Great Lakes into the Blue Ridge, running into a humid and unstable atmosphere. Forecasters highlighted the potential for wind damage, with an outside chance of small hail.
Happy Monday. Most of the day will be sunny & warm. However, there are some chances for rain today. A pop-up shower is possible in the early afternoon and a severe storm is possible close to midnight — as seen here on our forecast model.
