VALID 201200Z - 211200Z

...NO SVR TSTM AREAS FORECAST...

...SYNOPSIS...
SOME AMPLIFICATION OF THE BROADLY CYCLONIC UPPER FLOW FIELD COVERING
THE MAJORITY OF THE U.S. WILL OCCUR THIS PERIOD...AS PHASED
SHORT-WAVE TROUGHING DIGS SWD OUT OF CANADA AND ACROSS THE PLAINS
WITHIN THE WRN PORTION OF THE LARGER-SCALE TROUGHING. AS THIS
OCCURS...A SURFACE COLD FRONT -- AT THE LEADING EDGE OF A
REINFORCING SURGE OF COLD AIR -- WILL ADVANCE QUICKLY SEWD ACROSS
THE CENTRAL PLAINS...REACHING A POSITION FROM LOWER MI SWWD INTO SRN
OK/N TX BY THE END OF THE PERIOD.

AS SLY FLOW INCREASES ACROSS TX AHEAD OF THE FRONT...SHOWERS AND A
FEW THUNDERSTORMS MAY EVOLVE WITHIN THE GRADUALLY MOISTENING WARM
SECTOR DURING THE SECOND HALF OF THE PERIOD -- PARTICULARLY ACROSS
PORTIONS OF S TX AND THE MIDDLE AND LOWER TX COAST.
HOWEVER...SEVERE WEATHER IS NOT EXPECTED GIVEN AN
ANTICIPATED/OVERALL LACK OF CAPE.

THUNDERSTORMS WILL ALSO BE POSSIBLE ACROSS MUCH OF THE FL
PENINSULA...AHEAD OF THE LINGERING COLD FRONT AT THE LEADING EDGE OF
AN EARLIER SURGE OF COLD CONTINENTAL AIR. HOWEVER...CAPE/SHEAR
COMBINATION WILL BE INSUFFICIENT TO SUPPORT ANY APPRECIABLE SEVERE
RISK ACROSS THIS AREA AS WELL.
