Discussion
Two separate low pressure systems will bring significant rain and possible thunderstorms to the Mid-Atlantic region over the next 48 hours and also to much of the eastern 2/3rds of the nation where it has been quite dry in recent weeks. An eastward-moving frontal system has stalled out in the eastern US and this boundary zone will act as a conduit for copious amounts of moisture to ride along into the Mid-Atlantic region from the Deep South. By the time early Thursday rolls around, many locations along the I-95 corridor from DC-to-Philly-to-NYC will have received 2 or more inches of rainfall from the two different low pressure systems. The front finally clears through the region on Thursday and high pressure with colder conditions will follow for the late week and early weekend. Looking ahead, there can be another significant rain event during the early part of next week and cold air is likely to affect most of the nation by late in the week.
