Expect a rainy, windy and potentially hazardous Sunday afternoon as the Baltimore and Washington area faces a storm system that has swept through Midwestern and Southern states.

Scattered severe thunderstorms will move through the region Sunday morning into the afternoon, according to the National Weather Service. Winds outside of thunderstorms could near 50 mph, with a tornado watch for Allegany and Garrett counties.

NWS meteorologist Kyle Pallozzi said Saturday the primary threat in the Baltimore region would be wind.

The NWS’ Hazardous Weather Outlook included the Maryland portion of the Chesapeake Bay, Potomac River and Interstate 95 corridor through Central Maryland, Northern Virginia and the District of Columbia.

Despite the weather, Baltimore’s Shamrock 5K run downtown at 1 p.m. and 2 p.m. parade in Mount Vernon will proceed. They are advertised as taking place rain or shine.

The storm hits the East Coast after producing violent tornadoes and dust storms that killed dozens in the Midwest and the South.
