...SYNOPSIS...

STRONG SHORTWAVE TROUGH LOCATED OVER THE CNTL CONUS WILL EJECT
NORTHEAST THROUGH THE DAY 1 PERIOD.  COLD FRONT EXTENDING THROUGH
THE MS VALLEY WILL SURGE SOUTH AS COLD POLAR AIRMASS FOLLOWS IN THE
WAKE OF THE EJECTING S/W.  ANOTHER BOUNDARY LOCATED OVER NORTHERN
FL/SOUTHERN GA SEPARATES COOLER AIRMASS ASSOCIATED WITH HIGH
PRESSURE OVER THE NORTHEASTERN CONUS AND A MOIST...WEAKLY UNSTABLE
AIRMASS OVER THE FLORIDA PANHANDLE.

...FLORIDA...

12 UTC SOUNDINGS INDICATE MOIST ADIABATIC VERTICAL TEMPERATURE
STRUCTURE ACROSS MOST OF FLORIDA...AND WIDESPREAD STRATIFORM PRECIP

INSTABILITY DURING THE AFTERNOON.  NAM INDICATES A WEAK SFC WAVE/LOW
WILL DEVELOP ACROSS THE NORTHERN FL STATIONARY FRONT BY LATE
AFTERNOON...WHICH WILL THEN MOVE EAST/NORTHEAST ACROSS THE STATE AND
UP THE ATLANTIC COAST DURING THE OVERNIGHT HOURS.  NAM FCST
HODOGRAPHS INDICATE VERY FAVORABLE LOW AND DEEP LAYER VERTICAL WIND
SHEAR WILL EXIST AHEAD OF THE SFC LOW...WHICH WOULD FAVOR AN
ORGANIZED SVR THREAT.  HOWEVER...UNCERTAINTIES IN THE DEGREE OF
DESTABILIZATION ACROSS THIS REGION PRECLUDE A SLGT RISK AT THIS
TIME.
