The low is now SE of the Jersey Shore. This has arranged the flow pattern (white arrow) in a way that's saturating the atmosphere. On radar we can see precipitation back-filling into Eastern PA. I don't expect this to back-fill any further west. It should actually start pulling away to the east now. Temperatures at all layers are crashing below freezing from NW to SE...so soon it won't be long until even SENJ is snow. I've circled the areas of highest precipitation. Expect accumulations to start now throughout the region. The Be safe!
