The cross-country storm carrying severe weather to millions in the central U.S. this weekend stretches into the Northeast on Sunday and Monday, bringing heavy rain and the potential for flash flooding.

On Sunday, the storm, driven by a large dip in the jet stream, will be centered around the Great Lakes. Ahead of it, warm temperatures and abundant moisture will return to the region.

A Level 1 out of 4 flash flood risk is in place for parts of southwestern Pennsylvania, West Virginia and southeastern Ohio from Sunday night into Monday morning.
