Discussion
A “closed-off” upper-level low pressure system will continue to produce bands of showers today in the Mid-Atlantic region and there can be some strong thunderstorm activity as well during the afternoon and evening hours. The stubborn “closed” upper low will edge to the northeast on Wednesday as it “opens up” enough to get captured by the polar jet and our weather should improve at mid-week though a shower or two cannot be ruled out.
A cold front will then drop southeastward on Thursday crossing the Great Lakes and reaching the Mid-Atlantic region by late in the day. At the same time, another upper-level low will develop over the Mid-Atlantic region and surface low pressure is likely to form along the cold frontal boundary zone. The end result could be more showers and thunderstorms around here from later Thursday into Friday and perhaps even a period of steadier rain. The weekend could turn out to be pretty decent with increasing amounts of sunshine on Saturday and mostly sunny skies on Sunday. However, upper-level lows are notorious for throwing some curve balls to the weather forecaster so not quite ready yet to give the “all-clear” signal about the weekend.
