VALID 121200Z - 131200Z
...NO SVR TSTM AREAS FORECAST...
...SYNOPSIS...
LOW-AMPLITUDE MID-LEVEL FLOW PATTERN IS FORECAST ACROSS THE U.S.
THIS PERIOD...AS A TROUGH SHIFTS EWD ACROSS THE ERN U.S. AND INTO
THE WRN ATLANTIC. AS THIS FEATURE CROSSES THE EAST...AN ASSOCIATED
COLD FRONT WILL SHIFT SEWD/SWD ACROSS THE SRN STATES...FOCUSING
AFTERNOON CONVECTION. ELSEWHERE...WEAK RIDGING ALOFT IS FORECAST
ACROSS THE S CENTRAL U.S. AND INTO THE ERN ROCKIES...WHILE A SECOND
TROUGH REMAINS OVER THE ERN PACIFIC THROUGH THE PERIOD.
...COASTAL CAROLINAS AND VICINITY...
THE COLD FRONT SHIFTING SEWD ACROSS THE SERN U.S. AND SWD ACROSS THE
GULF COAST REGION/TX/NM WILL BE A FOCUS FOR DIURNAL DEVELOPMENT OF
SHOWERS AND THUNDERSTORMS...AS THE AIRMASS NEAR AND AHEAD OF FRONT
UNDERGOES MODEST AFTERNOON DESTABILIZATION.
WHILE KINEMATIC/THERMODYNAMIC COMBINATION SHOULD REMAIN LARGELY
INSUFFICIENT FOR APPRECIABLE SEVERE POTENTIAL...BELT OF SLIGHTLY
ENHANCED NWLY FLOW ALOFT IS PROGGED ACROSS THE CAROLINAS. THIS MAY
SUPPORT A SLIGHTLY GREATER CHANCE FOR SEMI-ORGANIZED
CONVECTION...AND THUS WILL MAINTAIN 5% HAIL/WIND POTENTIAL ACROSS
THIS AREA.
