There is the potential for locally gusty thunderstorms to affect portions of Ohio, Pennsylvania, West Virginia and upstate New York Friday and Friday night and then areas farther east on Saturday.
A disturbance will track east-northeastward from the Midwest.
The storms will bring a risk of damaging wind gusts, hail, blinding downpours and flash flooding to a few locations.
Part of the I-70, I-79 and I-80 corridors will be impacted Friday.
Cities in the general area that may experience strong thunderstorms during Friday include Columbus and Cleveland, Ohio, Pittsburgh and State College, Pa., Huntington and Morgantown, W.Va., and Elmira and Binghamton, N.Y.
During Saturday, the risk of locally damaging thunderstorms will shift to part of the I-81 and I-95 corridors from Roanoke, Va., and Raleigh, N.C., to Washington, D.C., Philadelphia and New York City.
In areas that have received heavy rain recently, there is an elevated risk of flash and small stream flooding.
