Sticky warmth spread from the south Atlantic Seaboard to the lower and middle Mississippi Valley will breed widely separated thunderstorms, mostly during the afternoons and early evenings.
Any such storm could shed a quick inch of rain within an hour or less--easily enough to spoil an outdoor barbecue, a jog or a round of golf.
Atlanta, Birmingham, Memphis and Nashville will number among the cities prone to a cloudburst on little warning.
Much of the South will stay quite warm and sticky, and thus subject to hit-or-miss thunderstorms, again on Wednesday.
