We're going to end March on a noisy note, with the threat of severe weather continuing until midnight. Storms have been developing since 4-5 PM along the I-81 corridor up into the South Mountain corridor in MD, and this activity will continue working east into the evening. The heart of the DMV, betw een I-81 and I-95, will feel the brunt of these storms until 9 PM. This includes the DC metro, where one thunderstorm has already come through with heavy rain and lightning. Locations east of I-95, mainly southern MD, won't likely see severe storms until closer to 8-9 PM, lingering around until midnight when they finally head east of the Chesapeake Bay. While locations to the west won't have to worry about the severe threat as much past 9 PM, some pockets of heavy rain are likely to linger until midnight behind the main line of severe storms. The main threats from any severe storms that develop will be damaging wind gusts and lightning, but hail and a rogue spin-up tornado can't be totally ruled out. Once the storms are gone with the cold front, it will turn cooler and breezy heading into Tuesday. Overnight lows will drop significantly compared to recent nights, with readings in the 30s and 40s by tomorrow morning. Highs tomorrow will struggle to get out of the 50s despite mostly sunny skies, mainly thanks to a consistent northwest wind around 10-20 mph pushing in chillier air. After the wind calms down briefly Tuesday night, it will switch to SE and pick back up again on Wednesday. This will lock in more clouds across the region as a warm front approaches, and keep temperatures in the lower to middle 60s. The rest of the week will be relatively quiet, but we are expecting a fair amount of soggy weather and fluctuating temperatures. With the warm front arriving by Thursday, overnight lows will stay much warmer Wednesday night and eventually lead to highs in the lower to middle 80s by Thursday afternoon. This major warmup will happen despite overcast skies and isolated showers being in the mix. This front will linger and eventually drift back south on Friday, keeping scattered showers on tap. It will cool off a little heading into Saturday, but the front will still be close enough for more isolated showers. Our highest chance for steady and widespread rain comes on Sunday as the front bounces back north and a cold front also swings by. Scattered showers and storms will be possible, followed by cooler air returning next Monday. Stay safe out there tonight, and have a great start to your Tuesday! 7-Day Forecast: Tonight: Mostly cloudy with rain and storms before midnight.
