16

TL/DR –

Severe storms are predicted for the Chesapeake Bay area and surrounding elevated terrains, particularly into the night, with the highest threat on Memorial Day. Wind damage, large hail, potential tornadoes, and flooding are possible hazards. The severe weather is due to a humid, unstable air mass, which will persist until a strong cold front passes on Monday night.

Two-part briefing: Storms tonight and Monday

Part 1, tonight: Vigorous storms similar to last night’s are possible, potentially strongest after 10 p.m. We’re watching the Ohio Valley as a storm complex moves towards the Appalachians, likely to weaken as it approaches our area.

Part 2, tomorrow: Widespread storms from noon to 9 p.m. may be organized and potent, triggered by a combination of the approaching cold front, upper level disturbance, unstable atmosphere, and strong winds aloft. Primary threats include damaging wind gusts, lightning, hail, and a couple of tornadoes. Flooding concerns are limited due to quick storm movement.
