Annandale, Va. – Virginia is enjoying a warm, mostly sunny Monday, but the calm weather won’t stick around for long. Sunshine is giving way to increasing humidity, and meteorologists are tracking a more active pattern that could bring repeated rounds of thunderstorms beginning Tuesday afternoon. Roads across Northern Virginia may quickly transition from dry pavement to heavy rain as a cold front approaches the region.
According to the National Weather Service, today stays mostly sunny with a high near 85 degrees before clouds gradually increase later in the day. A few showers or thunderstorms are possible late tonight, but the greatest concern arrives Tuesday. Showers and thunderstorms become increasingly likely during the afternoon and evening, with an 80% chance of rain during the day and a 90% chance Tuesday night. Some storms may produce heavy rainfall capable of creating localized flooding, especially in urban and poor-drainage locations.
Anyone traveling Tuesday should prepare for rapidly changing conditions. Motorists on Interstate 495, Interstate 395, Interstate 66 and Interstate 95, along with the George Washington Memorial Parkway, could encounter reduced visibility, ponding water and slower traffic during the afternoon and evening commute. Allow extra travel time and avoid driving through water-covered roadways.
High temperatures reach 88 degrees Tuesday before showers and thunderstorms become widespread. Southwest winds of 6 to 11 mph may gust to 21 mph, with stronger winds possible in thunderstorms. Frequent lightning will also pose a hazard for outdoor workers, youth sports and anyone planning afternoon activities. While the strongest severe weather is expected to remain north and west of the area, an isolated stronger storm cannot be ruled out.
Scattered showers linger into Wednesday, with another 60% chance of rain and highs near 86 degrees. Conditions improve noticeably Thursday as sunshine returns and temperatures settle near 81 degrees. Friday brings mostly sunny skies with highs around 82 degrees, providing a welcome break from the unsettled pattern. Longer-range outlooks suggest warmer-than-average temperatures could build back into the Mid-Atlantic later next week.
Stay weather-aware Tuesday, check the latest radar before heading out, and have multiple ways to receive weather alerts if you’ll be traveling or spending time outdoors.
