VALID 121300Z - 131200Z

...NO TSTM AREAS FORECAST...

...SYNOPSIS/FORECAST...
E PACIFIC RIDGE/CNTRL-ERN U.S. TROUGH PATTERN WILL PERSIST THIS
PERIOD AS SHORTWAVE IMPULSE NOW IN THE DAKS AMPLIFIES SE TO THE LWR
MS VLY. APPROACH OF THE VORT WILL INDUCE SFC WAVE DEVELOPMENT EARLY
TUESDAY ALONG FRONT NOW STALLING OVER THE SERN GULF OF MEXICO.
THIS WILL ENHANCE WAA/ELEVATED MOISTURE INFLOW...AND THE POTENTIAL
FOR EMBEDDED CONVECTION...AS RAIN DEVELOPS OVER NRN/N CNTRL FL.
ATTM IT APPEARS THAT POSITIVE TILT OF UPR TROUGH WILL KEEP MID LVL
LAPSE RATES WEAK. THUS CONVECTION LIKELY WILL REMAIN TOO FEEBLE
AND/OR SHALLOW TO SUPPORT THUNDER.
