The episode as NWS TBW wrote it up.

NWS Tampa Bay, FL wrote its last area forecast discussion before the first event at Jun 15, 12:50 PM EST, 4 hours 15 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE TAMPA BAY RUSKIN FL 150 PM EDT FRI JUN 15 2012 .SHORT TERM (TONIGHT - SUNDAY)... THE COMBINATION OF A DECAYING SFC BOUNDARY OVER SOUTHERN FL...NE FLOW PROVIDED BY PERSISTENT SFC HIGH PRESSURE NEAR THE EASTERN SEABOARD AND ENOUGH LOW LEVEL MOISTURE WILL KEEP GOOD CHANCES FOR THUNDERSTORMS AND SHOWERS LATE THIS AFTERNOON AND THROUGH THE EVENING HOURS. MAIN AREAS AFFECTED BY SIGNIFICANT THUNDERSTORMS SHOULD BE THE SOUTHERN ZONES OF THE CWA...BASICALLY THE INTERSTATE 4 CORRIDOR AND SOUTHWARD. AN AREA OF LARGE THUNDERSTORMS HAS ALSO DEVELOPED ON THE OPEN EASTERN GULF WATERS...WHICH IS NOW SLOWLY DRIFTING TOWARDS THE FL WEST COAST. NHC WILL CONTINUE TO CLOSELY MONITOR THE PROGRESS OF THIS SYSTEM...BUT TROPICAL DEVELOPMENT IS NOT ANTICIPATED AT THIS TIME. ONCE CONVECTION ACTIVITY ENDS TONIGHT...PLENTY OF CLOUD COVER/CONVECTIVE DEBRIS SHOULD LINGER OVER THE AREA BUT WITH OVERALL CONDITIONS BEGINNING TO BECOME DRIER AS HIGH PRESSURE ESTABLISHES TO THE NORTH OF THE STATE. FOR THE REST THE WEEKEND...SUBSIDENCE AND A DRIER AIRMASS WILL FILTER FROM THE NORTH AND BRINGING A BREEZY NORTHEASTERLY WIND FLOW. RAIN CHANCES ACROSS THE AREA DROP TO ISOLATED/20 PERCENT...AND EVEN DRIER ON SUNDAY. DAYTIME TEMPERATURES WILL GO BACK TO A FEW DEGREES ABOVE NORMAL EACH DAY WITH HIGHS CLIMBING INTO THE LOWER 90S WITH NEAR NORMAL LOWS IN THE 70S. .LONG TERM (SUNDAY NIGHT - THURSDAY)... U/L RIDGE WILL BEGIN TO BUILD OVER THE SOUTHEAST U.S. AND FLORIDA MONDAY...WITH HEIGHTS GRADUALLY INCREASING THROUGH THE WEEK WITH STRONG SUBSIDENCE OVER THE FORECAST AREA. SURFACE HIGH PRESSURE WILL HOLD OVER THE MID ATLANTIC THROUGH THE PERIOD WITH EASTERLY BOUNDARY LAYER FLOW EACH DAY. COMBINATION OF STRONG SUBSIDENCE... DRY AIR ALOFT...SLIGHTLY LOWER SURFACE DEW POINTS...AND EASTERLY FLOW WILL ALLOW DAYTIME TEMPERATURES TO CLIMB ABOVE CLIMATIC NORMALS WITH SOME REGIONS REACHING THE MID AND POSSIBLY UPPER 90S. MOS GUIDANCE ALTHOUGH ABOVE NORMAL...APPEARS SEVERAL DEGREES TOO LOW WITH MAX TEMPS. DRY AIR ALOFT AND STRONG SUBSIDENCE OVER THE FORECAST AREA WILL ONLY ALLOW FOR VERY LOW POPS EACH DAY...WITH PREDOMINATELY DRY CONDITIONS THROUGH THE PERIOD. && .AVIATION... VFR CONDITIONS AT ALL TERMINALS EARLY THIS AFTERNOON. THUNDERSTORM ACTIVITY NOW DEVELOPING FROM NORTH TAMPA BAY EASTWARD TO ORLANDO. THIS CONVECTION IS EXPECTED TO EVOLVE SOUTH/SOUTHWEST...WITH ALL TERMINALS INCLUDING ASSOCIATED TEMPOS FOR BRIEF THUNDER/MVFR RESTRICTIONS. BRIEF LOWER VIS RESTRICTIONS POSSIBLE WITH HEAVIER RAINS. ACTIVITY WILL DIMINISH DURING THE LATE EVENING. AREAS WITH SUBSTANTIAL RAINFALL MAY EXPERIENCE IFR/MVFR FOG/CIGS LATE NIGHT. POTENTIAL CAN BE REVISED ONCE RAINFALL PATTERNS ARE MORE CERTAIN. && .MARINE... A WEAKENING FRONTAL BOUNDARY ACROSS THE CENTRAL WATERS WILL CONTINUE TO DRIFT SOUTHWARD WHILE BREAKING APART THROUGH SATURDAY. HIGH PRESSURE BUILDS SOUTH ALONG THE EASTERN SEABOARD BEHIND THE FRONTAL PASSAGE WITH WINDS SHIFTING TO THE NORTHEAST...THEN EAST AND INCREASING LATER TONIGHT. EXERCISE CAUTION WILL BE RAISED FOR THE NORTHERN WATERS FOR THE 4 PM FORECAST ISSUANCE...AND WILL DEFER TO FOLLOWING SHIFTS TO EITHER EXPAND OR INCREASE TO ADVISORY IF NECESSARY. EASTERLY WINDS WILL PREVAIL ON SUNDAY AND THROUGH EARLY NEXT WEEK WITH AN EVENING SURGE OF WINDS LIKELY EACH DAY AS SURFACE HIGH PRESSURE PERSISTS NORTH OF THE WATERS. && .FIRE WEATHER... HIGH PRESSURE WILL BUILD INTO THE FL PENINSULA FROM THE NORTH/NE THROUGH THE UPCOMING WEEKEND...ALLOWING DRIER AIR TO ARRIVING ON DEEP EAST TO NORTHEAST FLOW. THE DRIER AIR WILL HELP LIMIT AFTERNOON/EVENING THUNDERSTORM ACTIVITY TO ONLY ISOLATED TO WIDELY SCATTERED ACTIVITY...WITH BEST CHANCES FOR RAIN OCCURRING FROM TAMPA BAY SOUTHWARD ALONG THE COAST. DESPITE THE DRIER AIR ARRIVING... CURRENTLY DO NOT ANTICIPATE ANY SIGNIFICANT AREAS OF CRITICAL RELATIVE HUMIDITY VALUES THROUGH AT LEAST SUNDAY. && .PRELIMINARY POINT TEMPS/POPS...
