Severe weather shifts to the Northeast, with heavy rains.
The NWS Storm Prediction Center (SPC) expects thunderstorms possible for much of the Eastern United States today.
Another round of showers and thunderstorms is in store for the East Coast through Tuesday morning. An upper level trough is continuing its trek eastward towards the coast; along with it, a mature frontal boundary on the surface, currently in the Mississippi River Valley, will make its approach near the coast on Monday evening. Deep moisture from the Gulf of Mexico along with unstable air will enhance conditions to spawn widespread coverage of convection throughout the East Coast. Coverage will increase by Monday afternoon, and with such an abundance of moisture heavy rainfall can be expected especially along the New England and Middle Atlantic coastline. By Tuesday evening, the surface front will be well offshore and thus most of the shower activity will be in the northern portions of New England.
