MOST OF THE SOUTHERN U.S. SCATTERED CONVECTION CONTINUES TO DEVELOP
ACROSS THE FORECAST AREA THIS AFTERNOON...AS A WEAK SHORT WAVE
INTERACTS WITH A MODERATELY UNSTABLE AND VERY MOIST AIRMASS. TSTORMS
SHOULD GRADUALLY DIMINISH IN AREAL COVERAGE AFTER SUNSET...ALTHOUGH
ISOLATED CONVECTION SHOULD CONTINUE OVERNIGHT WITH THE SHORT WAVE IN
THE AREA. MODELS INDICATE A LARGE AREA OF SUBSIDENCE MOVING ACROSS
THE REGION TOMORROW...WHICH SHOULD HELP TO SUPPRESS THE AREAL
COVERAGE OF CONVECTION. HOWEVER...AM CONCERNED THAT AN MCS COULD
DEVELOP ALONG A QUASI-STATIONARY FRONT OVER THE MIDWEST...AND MOVE
SOUTHEAST INTO THE FORECAST AREA LATE TOMORROW AFTERNOON AND
EVENING. THUS... WILL CONTINUE WITH 30 POPS FOR TOMORROW.

AND 80S ELSEWHERE. BEST CHANCE OF RAIN WILL BE AFTERNOON NORTH AND
EARLY EVENING SOUTH IF THE FRONT MOVES AS FAST AS EXPECTED. THE AIR
MASS WILL BE QUITE UNSTABLE AHEAD OF THE COLD FRONT. THE CAPE IS
FORECAST TO BE AROUND 3000 J/KG WITH ENOUGH DEEP LAYER SHEER FOR
POSSIBLE DAMAGING WINDS. AN MCS MAY BE ONGOING TO THE NORTH IN KY
AND COULD CONTINUE INTO THE TENNESSEE VALLEY AND SOUTHERN
