...NO SVR TSTM AREAS FORECAST...
A SPLIT FLOW PATTERN IS IN PLACE TODAY OVER THE UNITED STATES...WITH
THE SOUTHERN BRANCH OF WESTERLIES EXTENDING FROM NORTHERN MEXICO
ACROSS THE GULF OF MEXICO. A LOW-AMPLITUDE SHORTWAVE TROUGH OVER
THE SOUTHERN PLAINS WILL TRACK EASTWARD THROUGH THE FORECAST

EASTERN GULF COAST STATES. SCATTERED SHOWERS AND THUNDERSTORMS ARE
EXPECTED TO BECOME MORE NUMEROUS BY THIS AFTERNOON OVER THE FL
PENINSULA. LOW LEVEL MOISTURE WILL BE ON THE INCREASE OVER THIS
REGION...BUT CURRENT INDICATIONS ARE THAT WEAK INSTABILITY WILL
PRECLUDE THE RISK OF SEVERE STORMS. OVERNIGHT...THE THREAT OF
ISOLATED THUNDERSTORMS WILL SPREAD NORTHWESTWARD INTO PARTS OF
SOUTHERN AL/GA.
ELSEWHERE...ORGANIZED THUNDERSTORM ACTIVITY IS NOT EXPECTED TODAY.
