A mess of severe thunderstorms and flooding rain have swept up the East Coast Friday as far north as New York City and Washington, D.C.

Rainfall rates of 1 to 2 inches per hour quickly triggered flash flooding in parts of the New York Tri-State area around midday Friday. By early evening, these rainfall rates arrived in Boston and Providence, Rhode Island.
Several feet of water covered Route 44 in East Providence, Rhode Island during the evening commute.
Vehicles were stuck in flood water in Hackensack, New Jersey, and flooding was said to be widespread in Jersey City and in Willow Brook on Staten Island. At least one water rescue was performed in Newark.
Flooding prompted the closing of the main entrance into Penn Station, and water was seen cascading from the ceiling of the station.
The area of heavy rain is now pushing into southern New England. Flash flood watches are posted for parts of eastern New England, including the Boston and Providence metro areas, as well as Downeast Maine.

Current Radar, Watches and Warnings
Earlier Friday morning, the line of thunderstorms swept through Washington D.C., leading to some local flash flooding, after roaring through parts of the Carolinas and Virginia.
The National Weather Service confirmed an EF1 tornado touched down before sunrise near Oxford, North Carolina and an EF0 touched down near Edenton, North Carolina around 7:45 a.m., damaging a barn and trailer.
Another EF1 tornado downed numerous trees and damaged homes near Eden, North Carolina, near the Virginia border north of Greensboro, early Friday.
An EF1 tornado near McKenney, Virginia, early Friday morning damaged structures and downed trees. A trained spotter reported a funnel cloud with that segment of the squall line in Dinwiddie County. Winds are estimated to be between 85 and 95 mph.
Also in Virginia, an EF1 was confirmed in Dahlgren in King George County.

This is all occurring ahead of a cold front and rather vigorous southward plunge of the jet stream that will eventually evolve into a stalled-out, lumbering gyre of low pressure that will hover over the East for several days into next week.
Here are the severe weather forecast details on what to expect Friday.
