PREVIOUS DISCUSSION
CURRENTLY VISIBILITIES ARE IMPROVING OVER MUCH OF THE AREA AND
GIVING WAY TO GENERALLY PARTLY CLOUDY SKIES AND TEMPS IN THE 70S.
LIGHT S TO SE WINDS ARE PREDOMINANT.

A WEAK BOUNDARY IS LOCATED ACROSS NORTH FL AND THE ADJACENT GULF
WATERS AS A SHORTWAVE TROUGH SLIDES OVER THE FL PENINSULA. ANOTHER
LOW PRESSURE SYSTEM IS MAKING ITS WAY INTO THE NORTHEAST TRAILING A
FRONT  AND A VORT CENTER INTO THE THE SOUTHEAST. AFTERNOON/EVENING
SHOWERS AND THUNDERSTORMS ARE POSSIBLE AGAIN TODAY OVER LAND.

FOR THE MORNING UPDATES WILL REMOVE FOG WORDING. NO SIGNIFICANT
CHANGES ARE NEEDED AT THIS TIME.

PREVIOUS DISCUSSION.*************************************************
SYNOPSIS: SEA BREEZE COMBINED WITH A WEAK TROUGH IN THE NORTHEAST
GULF AND AN UPSTREAM SHORT WAVE TROUGH TO TRIGGER A FEW SHOWERS AND
THUNDERSTORMS ACROSS THE REGION YESTERDAY. LAST OF THE CONVECTION
STUBBORNLY HANGING ON ACROSS WRN LEE CO GA AT PRESS TIME. SURFACE
ANALYSIS SHOWS THE FRONT HAS NOT MOVED MUCH ACROSS CENTRAL FL AND
CONTINUES TO EXTEND WWD ACROSS THE CENTRAL GULF. AS SUSPECTED, GULF
LOW ADVERTISED BY THE GFS HAS NOT MATERIALIZED. WATER VAPOR IMAGERY
SHOWS THE SHORT WAVE TROUGH REMAINS TO OUR W, EXTENDING FROM WRN AL
S INTO THE NE GULF. DRY AIR IS NOTABLE BEHIND THIS AXIS. SATELLITE
ALSO SHOWS HIGH CLOUDS STREAMING NWD INTO THE AREA FROM CONVECTION
IN THE SE GULF, AND LOW CLOUDS MOVING NWD FROM THE GULF INTO THE WRN
PANHANDLE.

MODEL DISCUSSION: SHORT WAVE TROUGH IN THE SE CONUS AND NE GULF
APPEARS A LITTLE SHARPER THAN SHOWN IN THE MODELS. GFS CONTINUES TO
BE PLAGUED BY CONVECTIVE FEEDBACK TO OUR S AND THEN E TODAY. THE
MAIN VORT CENTER TO OUR W APPEARS BEST HANDLED BY THE ETA, BUT ALL
SHOW IT WEAKENING AS IT MOVES EWD ACROSS THE LOCAL AREA. THE AXIS
WILL NOT BE E OF THE AREA UNTIL LATE IN THE DAY, SO IT MAY HELP
ENHANCE AFTERNOON POPS A BIT ACROSS OUR ERN ZONES. THIS AREA WILL
ALSO HAVE GREATER MEAN RH AND LOW LEVEL CONVERGENCE TODAY. BY FRI,
THE FRONT TO OUR W WILL BEGIN TO AFFECT OUR WX. CURRENT POP
DISTRIBUTION LOOKS FINE. BEYOND 48 HOURS, THE ETA AND GFS BEGIN TO
DIVERGE WITH THEIR HANDLING OF THIS FEATURE. THE ETA HANGS THE FRONT
UP TO OUR N, WHILE THE GFS SHOWS A DEFINITIVE FROPA FRI NIGHT.
CONSIDERING THE MODEL TRENDS TOWARD AMPLIFICATION, I WOULD TEND TO
BELIEVE THE GFS. INCLINED TO PULL SHOWERS FROM SAT FORECAST. BECAUSE
OF THIS, WILL ALLOW FOR 90 DEGREE TEMPS ON SAT AT TLH AS DRIER AIR
MOVES IN AND HEIGHTS RISE.

MARINE: NO HIGHLIGHTS ANTICIPATED OVER THE NEXT 5 DAYS. ELY FLOW
REGIME SET TO TRANSITION TO SWLY TODAY AND THEN WLY FROM TONIGHT
THROUGH SAT. S FLOW COMMENCES ON SUN. GFS STILLS SHOWS POTENTIAL FOR
MARGINAL CAUTION EVEN LATE SUN NIGHT INTO MON, BUT WILL KEEP
FORECAST JUST BELOW FOR NOW AT 15 KT.

FIRE WX: NO RED FLAG CONDITIONS EXPECTED THROUGH FRI, ALTHOUGH
SOMEWHAT DRIER AIR WILL BRING MINIMUM RH BELOW 40 PERCENT ACROSS
SOME ERN INLAND AREAS.

EXTENDED: WEAK FRONT PIVOTS BACK TO THE NE ACROSS THE AREA ON SUN.
HOWEVER, GFS INDICATES LIMITED MOISTURE AN NO LIFT ASSOCIATED WITH
THIS FEATURE BY THAT TIME AND DRY FORECAST STILL LOOKS GOOD.
MOISTURE THEN INCREASES STEADILY FROM NE TO SE OVER THE NEXT FEW
DAYS AS THE NEXT FRONTAL SYSTEM APPROACHES FROM THE W. LOOKING FOR
FROPA TUE NIGHT INTO EARLY WED.
