Tropical System in the Gulf; Dangerous Heat and Air Quality Concerns; Severe Thunderstorms for Midwest to mid-Atlantic

Tropical system in the Gulf expected to gradually strengthen the next couple of days off the Florida Panhandle and Alabama coasts. Instances of flash flooding will be possible through Thursday along the eastern and central Gulf Coast. Severe thunderstorms will develop and move along a cold front crossing the Upper Midwest, and through the Ohio Valley/Mid-Atlantic on Tuesday. Read More >

The environment on Tuesday is favorable for storms to also produce torrential downpours, which may lead to isolated to scattered flash flooding. All of eastern Kentucky is under a Slight (Level 2/4) Risk for Excessive Rainfall. The most likely timing for storms with torrential downpours is Tuesday afternoon/evening.
The primary severe weather hazard will be damaging straight-line wind gusts from one or more lines of thunderstorms. Isolated tornadoes and hail to around quarter-sized are also possible, mainly from scattered storms ahead of the line(s).
