PM Update: Scattered storms this evening; drier air trickles in on a warm Wednesday

After a round of morning downpours, we’ve had a warm, humid day. Enough sun has snuck through the expansive cloud cover to elevate temperatures into the upper 70s. A slow moving cold front brings the potential for showers and storms this evening, then drier air creeps into the region into Wednesday. However, another cold front could set off a stray shower/storm late in the day.

Through Tonight: Storm potential appears a little less widespread than just a couple hours ago. Nevertheless, scattered showers and storms are likely to be around through late this evening. A few storms could be strong with gusty winds, small hail, lightning and downpours, but the risk of severe weather is higher south of the D.C. region. Storms decrease in coverage and intensity between 10 p.m. and 1 a.m. Then it’s mostly cloudy with lows 60-65.

Wednesday: Skies become partly sunny and humidity levels decline as drier air comes in from the west. Still, there’s a 20 percent chance of showers and thundershowers late in the day as a cold front swings through the region. It’s a warm one, with highs 80-84.
