Senior meteorologist Matthew Cappucci of private weather forecaster MyRadarWX is monitoring the potential for isolated tornadoes along the Interstate 95 corridor, from areas north of Washington, D.C., through Baltimore and Wilmington, Delaware, and into the Philadelphia metro area.

Brief tornado possible IF southward-sagging front doesn't undercut storms too quickly," Cappucci wrote on X earlier this morning.
