A potent winter storm is forecast to bring more than a foot of heavy wet snow to portions of interior New England; however, it is also forecast to bring heavy rain to a large part of the east coast, creating some flooding concerns. Some of the biggest flooding concerns are in an area that just don’t need any more rain: New Jersey, Long Island, southern coastal New England, southeastern Pennsylvania, Delaware, and eastern Maryland and Virginia.
Generally 1-3″ of rain can fall over a short period of time, especially in the northern Mid Atlantic and southeastern New England areas. There is even a risk of thunderstorms as a cold front associated with the storm moves through the DelMarVa region.
Cold air is quickly arriving behind this storm, but most precipitation will be off-shore before it arrives. So while accumulating snow isn’t expected after heavy rain in places like Providence, New York City, Philadelphia, and Baltimore, a quick freeze is. With temperatures dropping into the 20s tomorrow, any untreated wet surface could freeze.
