Discussion
There is a growing chance that a prolonged and significant rain event is coming to the Mid-Atlantic region…something not seen in these parts in quite awhile.
While there can be some shower and thunderstorm activity from later today into later Saturday, the main event likely begins on Saturday night with heavier and steadier rainfall and then rain is likely to be a threat on Sunday, Monday, Tuesday, and perhaps even Wednesday as well. A warm front lifts through the region tonight with some shower activity and then Friday will turn into a very warm and humid day with scattered showers and thunderstorms…much of the day should be rain-free. On Saturday, a cold front will head towards the eastern US and showers and thunderstorms will become increasingly likely by the time we get to Saturday evening. Some of the rain late Saturday/Saturday night can be heavy at times with the arrival of the cold front and there can be strong-to-severe thunderstorm activity included.
Looking ahead, the upper-level pattern will evolve into an “omega-block” situation and one that can produce occasional rain and cooler conditions in the Mid-Atlantic region from Sunday into the middle of next week. Some of this rainfall during the first half of next week can be heavy at times and this unfolding scenario could put a real dent in any drought conditions that remain in the area.
