A very active weather pattern is setting up for the next week or two partly as a result of continuing cold air outbreaks into the central and eastern US. These cold air outbreaks will combine with increasing warmth and moisture across the southern US to make it quite unstable on many days going forward in many parts of the nation. In the short-term, a warm front will generate showers and thunderstorms in the DC-to-Philly-to-NYC corridor from later today into Wednesday and some of the storms that form can be on the strong-to-severe side. A strong cold front will then drop southeastward across the area later Thursday and it will be accompanied by showers, perhaps a strong thunderstorm, and increasing winds which will remain quite powerful on Thursday night and Friday. Another storm system could impact the Mid-Atlantic region late in the weekend or by the early part of next and then another system could follow a few days later in this unfolding very active weather pattern.
A warm front is advancing slowly to the north and east today stretching from the Upper Midwest to the southern Mid-Atlantic. Showers and thunderstorms are pushing along this frontal boundary zone and it looks like there may be multiple bands that will impact the DC-to-Philly-to-NYC corridor from later today into Wednesday. Some of the storms that form in this pattern can be on the strong-to-severe side from later today into the day on Wednesday with the highest probability from southern PA to the DC metro region to the Delmarva Peninsula. Any strong storm can contain damaging wind gusts and potentially some small hail as the warm front advances slowly to the north and east. On Wednesday, temperatures will climb to warmer levels in the 70’s on the backside of the frontal system and there will be a continuing threat of showers and possible strong-to-severe thunderstorms in much of the Mid-Atlantic.
