The severe weather setup this week looks like an early-spring storm that is pulling warm, humid air from the Gulf of Mexico. The warmth continued to fuel thunderstorms Wednesday afternoon to early Thursday morning, as they push across the Southeast, mid-Atlantic and New England.
Impacts from the storms include damaging winds, quarter- to half dollar-size hail and, possibly, large, long-lived tornadoes.
