WEST CENTRAL AND SOUTHWEST FLORIDA FORECAST DISCUSSION NATIONAL WEATHER SERVICE TAMPA BAY AREA - RUSKIN FL 1250 PM EDT TUE JUN 20 2000 LOOKS LIKE MORE OF THE SAME FOR THE NEXT COUPLE OF DAYS. IN FACT... PCPN COVERAGE MAY ACTUALLY INCREASE AS WEAK IMPULSES SLIDE DOWN THE BACK SIDE OF THE SLOWLY RETROGRADING H50 RIDGE. IN SHORT...WE'RE LOOKING AT HIGH CHC/LKLY POPS...ESP FROM MID AFTERNOON UNTIL MIDNIGHT...WITH THE COASTAL COUNTIES GETTING THE LION'S SHARE. ALL MODELS HAVE CHANGED THEIR TUNE A BIT SINCE YESTERDAY. UPPER TROUGH SLIDING INTO THE MIDWEST WED THROUGH THU IS A BIT WEAKER... ALLOWING H50 RIDGE TO REMAIN ANCHORED FROM THE NW GULF THROUGH THE GA COAST. IN RESPONSE...FLOW BETWEEN H85 AND H50 REMAINS SOLIDLY ENE AT 10-20 KT (OR MORE) RATHER THAN 10 KT TWD H50...AND VRBL TWD H85. THIS WILL ALLOW A CONTINUED ENE-WSW STEERING COMPONENT WHICH WILL PREVAIL THROUGH EARLY THURS. THE ETA/AVN ARE STILL HINTING AT A SLOW SWITCH TO LIGHT W/SW FLOW LATER THURS IN RESPONSE TO CONTINUE RETROGRESSION OF THE H50 RIDGE...AS WELL AS FLATTENING. HOWEVER... THIS REMAINS TO BE SEEN. THE FCST: REST OF THIS AFTN/TONIGHT...CONVECTIVE TEMP AT 91 AND WE SHOULD ARRIVE THERE WITHIN AN HOUR. SEA/BAY BREEZES HAVE ALREADY KICKED IN. EXPECT CONVECTION TO FIRE ON THESE BREEZES BY 1 OR SO... THEN MORE FARTHER INLAND BETWEEN 2 AND 4 PM. EACH WILL SET OFF BOUNDARIES STARTING MORE ACTIVITY...WHICH EVENTUALLY WILL FORM A BROKEN LINE THAT WILL PUSH BACK TOWARD THE COAST DURING THE EVENING. WILL GO SCT INTERIOR...LKLY COAST...BECOMING FAIR OVERNIGHT. WED THROUGH THURS...NO REASON TO GET CUTE. AVN IS QUITE BOLD WITH PCPN SLIDING TO THE COAST DURING THE EVENING AND CONTINUING WELL INTO THE NIGHT...A RESULT OF ENHANCEMENT FROM H50 IMPULSE SLIDING SW. COME TO THINK OF IT...ALL MODELS SHOW THIS IMPULSE TO SOME DEGREE. FOR NOW...PREFER 50 POP JUST ABOUT EVERYWHERE...DIPPING TO 40 (EVENING) INLAND. WITH UNCERTAINTY ABOUT AFTER MIDNIGHT PCPN WILL KEEP TIMING OUT FOR THE COASTAL COS. WITH PCP WATER VALUES RISING TOWARDS 2 INCHES...EXPECT CONTINUED THREAT FOR LOCALLY TORRENTIAL RAINS...AND A DECREASING THREAT FOR LARGE HAIL. EXTENDED: MORE OF THE SAME THROUGH THE WEEKEND. MARINE: WILL RE-INTRODUCE A SW FLOW N LEG THUR/FRI...OTHERWISE L/V WINDS BECOMING ONSHORE EACH AFTERNOON. FIRE WX: NO PROBLEMS ANTICIPATED. PRELIM NUMBERS: TPA TT 074/092/074/091 44y44 FMY TT 073/092/073/092 4545 88 .TBW...NONE. GOLDSMITH
