Slight risk areas cannot rule out damaging storms on Monday.

A few severe thunderstorms are expected Monday afternoon and evening from South Dakota into northern Minnesota, and during the day from Pennsylvania into New York and Vermont. Isolated severe storms are expected from Wyoming into Nebraska, across the Appalachians, and across southern Arizona.

Supercell formations are possible, given the weak capping convection and instability. This means that damaging storms are possible, as well as hail and gusty wind. Isolated tornadoes cannot be ruled out in the slight risk area.

Stay up to date by following the Pennsylvania Weather Authority and the NWS for any alerts that may be issued.
