WEST CENTRAL AND SOUTHWEST FLORIDA FORECAST DISCUSSION NATIONAL WEATHER SERVICE TAMPA BAY AREA - RUSKIN FL 155 PM EDT FRI JUN 15 2001 CURRENT FCST TRENDS IN FINE SHAPE...AND WILL MAKE FEW CHANGES TO THE OVERALL GIST OF THE PACKAGE. IN GENERAL...A DRY WEEKEND UPCOMING BY MID JUNE STANDARDS IN FL...BUT MODEL TRENDS CONTINUE TO INDICATE A GRADUAL INCREASE IN CHANCES AND COVERAGE OF PCPN FOR NEXT WEEK. MODELS ARE IN GOOD AGREEMENT THROUGH 24H. APPEARS THAT AVN BEST HANDLED SLOW N CREEP OF ALLISONS REMAINS. NOW...ALL MODELS QUICKLY ENVELOP THE SHORT WAVE INTO THE APPROACHING SYSTEM BY SAT. FOR US...THE PRIMARY MODEL DIFFERENCE BEYOND 24H IS THE HANDLING OF SHORTWAVE ENERGY SLIDING INTO THE MIDWEST TONIGHT THEN DIVING SE TOWARD FL LATER SAT AND SUN. NGM IS THE WEAKEST WHILE ETA STRONGEST...WITH AVN IN BETWEEN. WITH SYSTEM SLIDING INTO AN EXISTING WEAKNESS AT H50 BELIEVE THE NGM A BIT TOO FAST TO DAMPEN... BUT ETA MAY BE OVERDONE ATTM. FAVOR THE AVNS BIG PICTURE THIS TIME AROUND. SHORT TERM: WILL MONITOR ISOLD/SCT AFTN CONVECTION FOR WIND/HAIL EVENTS. THEREAFTER...SKIES SHOULD CLEAR OUT ONCE AGAIN. TRICKY CALL NEAR THE COAST AS CURR FCST CARRIES ISOLD LATE NIGHT PCPN. NEW RUNS SHOW N TO NW FLOW DEEPENING TWD DAWN...BUT MOISTURE IN THE NW FLOW REGIME IS LIMITED SO WILL REMOVE. FOR SAT...SOUNDINGS ARE SIMILAR TO THIS MORNINGS OBSERVED...ONLY WITH SLIGHTLY LOWERED CAPE/LI AND A DEFINITIVE NW FLOW. THE EXCEPTION IS THE SW CORNER WHERE LIGHTER WINDS PREVAIL. WILL BACK OFF TO ISOLD PCPN. A TURN TO THE WNW COMBINED WITH INCREASING LOW LVL MOISTURE ARGUES FOR A BETTER SHOT AT PCPN NEAR THE COAST COME EARLY SUN. SUN ITSELF COULD GET INTERESTING AS MID LEVEL DRY AIR MOVES IN...AT LEAST ACROSS THE N 2/3 OF THE CWFA AND SHORT WAVE APPROACHES IN NNW FLOW ALOFT. FOR NOW A BIT TOO SOON TO SPECULATE...AND WOULD RATHER ERR ON THE SIDE OF CAUTION...SO WILL BUMP PCPN CHANCES UP A TAD IN ALL AREAS. EXTENDED: OLD SFC TROUGH GIVES WAY TO LIGHT...BUT IMPORTANT...E FLOW. INITIALLY RETROGRADED UPPER RIDGE EXPANDS BACK TO THE E...N OF THE STATE...AND THIS SHOULD HELP DEEPEN THE E FLOW. OLD POOLED MOISTURE WOULD HELP THE CAUSE. IN BRIEF...WILL LEAVE GIST OF EFP ALONE WITH EXPECTATION OF MORE TYPICAL TEMP/PCPN PATTERN MON THROUGH FRI. MARINE: CURR FCST TREND LOOKS RIGHT ON...SO ONLY A FEW TWEAKS PLANNED. FIRE WX: DRIER AIR MIXING TO SFC WILL CREEP AFTN RH VALUES TWD 35-40 PERCENT IN CENTRAL ZONES SAT...BUT STILL NOT ENOUGH FOR WATCH CRITERIA DESPITE AN OCCASIONAL GUST TO 15 MPH. HOWEVER...ISOLD/SCT TSTMS CAN STILL PROVIDE FIRE IGNITIION FROM LIGHTNING STRIKES. UNTIL DEEP AND WIDESPREAD PCPN OCCURS...THIS WILL REMAIN AN ONGOING THREAT.
