Severe thunderstorms are increasing in coverage across the Ohio Valley and Northeast. The violent thunderstorms will eventually reach the I-95 corridor.
The strongest thunderstorms through Saturday evening will continue to threaten communities with damaging winds, frequent lightning and flooding downpours.
A handful of thunderstorms will also produce hail, while an isolated tornado cannot be ruled out.
The beneficial aspect of the severe weather is that more comfortable air will follow for many on Sunday.
