   ...SYNOPSIS...
   AS A SIGNIFICANT MID-LEVEL IMPULSE PROGRESSES INLAND...ACROSS AND TO
   THE LEE OF THE CANADIAN ROCKIES...MODELS INDICATE THAT RIDGING OVER
   INTERIOR WESTERN NORTH AMERICA WILL FLATTEN AND FLOW WILL BECOME
   MORE ZONAL DURING THIS PERIOD.  HOWEVER...FURTHER AMPLIFICATION OF
   LARGE-SCALE MID/UPPER TROUGHING APPEARS LIKELY ACROSS THE EASTERN
   U.S...COINCIDENT WITH THE CONTINUED SOUTHEASTWARD PROGRESSION OF A
   SIGNIFICANT LOW-LEVEL COLD INTRUSION ACROSS THE GULF COAST INTO THE
   GULF OF MEXICO...AND ACROSS THE ATLANTIC SEABOARD INTO THE WESTERN
   ATLANTIC.  BY 12Z WEDNESDAY...THE LEADING EDGE OF THIS AIR MASS AT
   THE SURFACE MAY REACH SOUTHERN PORTIONS OF THE FLORIDA PENINSULA. 
   THESE DEVELOPMENTS ARE EXPECTED TO REINFORCE GENERALLY STABLE
   CONDITIONS ACROSS MUCH OF THE U.S...WITH CONVECTIVE POTENTIAL
   REMAINING LOW TO NEGLIGIBLE TUESDAY AND TUESDAY NIGHT.

   ...FLORIDA PENINSULA...
   THE OPERATIONAL NAM...IN PARTICULAR...APPEARS TOO AGGRESSIVE WITH
   MOISTENING AND DESTABILIZATION ACROSS THE INTERIOR FLORIDA
   PENINSULA...ESPECIALLY NORTH CENTRAL PORTIONS.  HOWEVER...LOCALLY
   ENHANCED LOW-LEVEL CONVERGENCE...AT LEAST NEAR SOUTHERN COASTAL
   AREAS...MAY SUPPORT WIDELY SCATTERED DAYTIME AND EVENING
   THUNDERSTORM ACTIVITY...AIDED BY LARGE-SCALE FORCING FOR UPWARD
   VERTICAL MOTION AHEAD OF THE DIGGING SOUTHERN PORTION OF THE
   APPROACHING UPPER TROUGH.
