Overview
- Following Wednesday’s near-record heat from Washington to Boston, a cold front is triggering afternoon and evening thunderstorms and a sharp cool-down for Thursday and Friday.
- South Florida remains locked in breezy onshore flow, with morning coastal showers shifting inland to afternoon storms and a high risk of rip currents along Atlantic beaches through Wednesday evening.
- New Orleans flags Impact Days through Saturday for heavy rain and possible flash flooding as daily storms expand, and forecasters in Kentucky issued a Wednesday morning flash flood warning for Crawford County after slow-moving downpours.
- Late week into Memorial Day, a slow or stalled front near the Southeast is expected to boost scattered storms from Georgia into the Carolinas and parts of the Mid-Atlantic, though many spots still get long dry stretches for outdoor plans.
- The West trends warmer and dry under building high pressure, with the Pacific Northwest and California interior heating up through late week before marine clouds bring slight coastal cooling into the weekend.
