VALID 211200Z - 221200Z

...NO SVR TSTM AREAS FORECAST...

...DISCUSSION...
SLOW PROGRESSION OF THE UPPER FLOW PATTERN WILL OCCUR MONDAY...AS A
LARGE UPPER TROUGH SHIFTS GRADUALLY EWD WHILE UPSTREAM RIDGING
SPREADS ACROSS THE WEST. AS THIS OCCURS...A REINFORCING SURGE OF
COLD AIR AT THE SURFACE WILL CONTINUE TO SPREAD SEWD ACROSS THE SRN
AND ERN CONUS.

WITH COOL CONTINENTAL AIR PREVAILING ACROSS MOST OF THE COUNTRY E OF
THE ROCKIES...THUNDERSTORM RISK WILL REMAIN CONFINED TO AREAS S OF
THE REINFORCING COLD FRONT. SHOWERS AND A FEW THUNDERSTORMS MAY
OCCUR ACROSS PARTS OF TX...AND ALSO ACROSS THE FL PENINSULA WHERE A
WARMER/MORE MOIST BOUNDARY LAYER WILL PERSIST. HOWEVER...CAPE/SHEAR
COMBINATION SHOULD REMAIN INSUFFICIENT FOR APPRECIABLE SEVERE RISK
THROUGH THE PERIOD.
