July is quickly coming to a close, and it’s going out muggy and wet. The DC area saw some scattered showers and lightning today, with the majority staying further north, as expected. Temperatures also reached 100° at Washington National Airport, with the heat index climbing into the mid-100s. More rain is on its way–read on for today’s forecast update!
Rain will once again affect the DC Metro tomorrow as a cold front moves southward through the area. Expect rain and scattered thunderstorms ahead of the front, especially in the afternoon hours. Rain will continue into the evening, dissipating overnight. The SPC has issued a slight risk of severe weather for Southern Maryland and Virginia for tomorrow. Most of the strongest storms should develop south of DC later in the afternoon where the atmosphere will be much less stable. A stray strong thunderstorm with gusty winds and hail still cannot be ruled out for anywhere in the DC area throughout tomorrow afternoon. Temperatures will remain hot and muggy in the mid-90s—another heat advisory is currently in effect from noon tomorrow through 7pm, mainly for areas south of I-95. Expect heat indices again around 105° for these areas.
The cold front will stall south of the area Saturday, leading for the continued chance for scattered showers and thunderstorms throughout the area in the early afternoon. The front will begin to move out again later Saturday as high pressure moves in from the west.
Sunday is looking to be better, with the high pressure bringing mostly sunny skies, and the cold front’s passing leaving us with slightly cooler temperatures around 90°.
Monday and Tuesday look to end the month with some mugginess returning, although temperatures will remain around normal—the same as Sunday. Scattered rain is expected throughout the first half of the week.
