...NO SVR TSTM AREAS FORECAST...
...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.
