...SYNOPSIS...
IN MID-UPPER LEVELS...RELATIVELY STRAIGHTFORWARD SYNOPTIC PATTERN
WILL CONTINUE WITH TROUGHING FROM HUDSON BAY REGION TO GA...AND
RIDGE OVER ROCKIES. SLOW-MOVING LOW-LEVEL COLD FRONT EXTENDS FROM
NRN BAHAMAS WSWWD ACROSS S FL...AND WILL CONTINUE TO DRIFT SWD.
...S FL...
UNMODIFIED 00Z EYW/MFL SOUNDINGS APPEAR TO REPRESENT MARINE AIR MASS
THAT WILL BE SHUNTED LARGELY OFFSHORE FROM MAINLAND FL OVERNIGHT BY
LAND-BREEZE PROCESSES ALONG/S OF FRONT...ALTHOUGH DEEP LAYER OF
ELY/NELY FLOW FROM SFC-700 MB MAY BOOST LOW LEVEL THETAE ENOUGH TO
SUPPORT SOME INLAND MAINTENANCE OF RELATIVELY HIGH-THETAE AIR OVER
PORTIONS S FL. SOUNDINGS EXHIBITED SUFFICIENTLY DEEP CAPE INTO
MID-UPPER LEVEL ICING LAYERS TO POSE MRGL TSTM POTENTIAL...ALTHOUGH
BOUNDARY LAYER FORCING FOR VERY DEEP CONVECTION WILL BE RATHER
LIMITED...GIVEN LACK OF MORE ROBUST CONVERGENCE.
