Discussion
Some spots in the Mid-Atlantic region were hit by drenching showers and thunderstorms this past weekend while other locations (often right nearby) received much less rain than anticipated. There will be opportunities for more rain in all areas through tomorrow night and some of the rain can be heavy at times. A slow-moving upper-level low pressure system currently centered over the Ohio Valley will continue to produce unstable atmospheric conditions in the region leading to additional bands of showers and thunderstorms.
While the weather settles down a bit on Wednesday as the upper-low grudgingly lifts its way to the northeast of here, there can still be a few showers in the area and perhaps even a thunderstorm or two. A cold front will then drop southeastward on Thursday crossing the Great Lakes and reaching the Mid-Atlantic region. At the same time, an upper-level low will try to re-develop over the Mid-Atlantic region and low pressure may form along the frontal boundary zone. The end result could be more showers around here later Thursday and potentially even some steadier rain from Thursday night into Friday. The weekend may turn out pretty well assuming the late week systems push off to the north and east of here.
