The episode as NWS TAE wrote it up.
A weak upper level trough combined with a moist and unstable air mass to produce isolated severe thunderstorms across portions of the Florida panhandle.

NWS Tallahassee, FL wrote its last area forecast discussion before the first event at Aug 8, 1:24 PM CST, 1 hour 26 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE TALLAHASSEE FL 324 PM EDT MON AUG 8 2011 .SYNOPSIS...ACTIVE SEA BREEZE DAY IN PROGRESS ACROSS NORTH FLORIDA TODAY WITH NUMEROUS SHOWERS AND THUNDERSTORMS DEVELOPING AND SPREADING WESTWARD. IT TOOK A LITTLE WHILE...BUT CONVECTION HAS ALSO STARTED TO DEVELOP ACROSS OUR NORTHERN ZONES AS WELL. AS HAS BEEN THE CASE FOR THE LAST COUPLE OF DAYS...IT HAS BEEN QUITE HOT ACROSS SOUTHERN GEORGIA/ALABAMA WITH DEWPOINTS REFUSING TO MIX OUT. ALBANY HAS HELD AN 80 DEGREE DEWPOINT MUCH OF THE DAY...WITH AN OBSERVATION AT 18Z OF 95/80! && .SHORT TERM...(MONDAY THROUGH WEDNESDAY). MODEL GUIDANCE SHOWS THE CURRENT LOW PRESSURE SYSTEM JUST NORTH OF THE DAKOTAS MOVING EAST OVER THE FORECAST PERIOD. THIS SYSTEM WILL BE WEAKENING THE RIDGE ALOFT CAUSING IT TO RETROGRADE ACROSS THE MID SOUTH BACK INTO WEST TEXAS. THESE SLIGHT HEIGHT FALLS WILL ALLOW FOR A BETTER THERMODYNAMIC ENVIRONMENT FOR SHOWER AND THUNDERSTORM DEVELOPMENT. ADDITIONALLY IN THIS PATTERN...A SHORTWAVE WILL MOVE OUR WAY ON TUESDAY INCREASING POPS FOR THE EARLY PART OF THE FORECAST PERIOD. MODEL GUIDANCE IS SHOWING TUESDAY TO BE MUCH LIKE TODAY...WITH LOTS OF CONVECTION IN THE MORNING AND EARLY AFTERNOON NEAR THE COAST BUILDING INLAND THROUGHOUT THE DAY. THUS TOMORROW LOOK FOR 60 PERCENTS ONCE AGAIN IN FLORIDA SPREADING INLAND TOWARD DOTHAN AND VALDOSTA. ELSEWHERE...POPS WILL BE AT 50 PERCENT. FOR WEDNESDAY GUIDANCE WAS SPLIT AS SOME DRIER AIR WILL BE MOVING IN BY THURSDAY. FOR THE FORECAST A BLEND OF THE TWO MODELS WAS DECIDED AS WELL AS A FORECAST BASED ON PERSISTENCE. AS THERE IS SO MUCH MOISTURE IN THE REGION...IT WILL LIKELY TAKE MORE TIME TO DRY OUT...MAKING WEDNESDAY A TRANSITION TYPE DAY. SHOWERS ALONG THE COAST IN THE MORNING HOURS ONCE AGAIN AND BUILDING INLAND THROUGHOUT THE DAY WITH THE SEA BREEZE. FLORIDAS POPS WILL BE IN THE 40S WHERE MORE OF THE MOISTURE WILL STILL LINGER. 30 PERCENT WAS PUT IN AT DOTHAN...AND ONLY 20 FOR ALBANY WHERE THE DRIER AIR SHOULD BE. 50 PERCENTS ARE LEFT IN NEAR CROSS CITY AND THE COASTAL BIG BEND WHERE STRONG WEST WINDS WILL BETTER SUPPORT THE SEA BREEZE ALLOWING FOR STORMS TO CONGREGATE THERE THROUGHOUT THE DAY. TEMPERATURES WILL CONTINUE TO BE A FEW DEGREES ABOVE NORMAL. SHOULD STAY AWAY FROM UPPER 90S ON TUESDAY...EXCEPT NEAR VLD. WARMER TEMPERATURES ARE EXPECTED ON WEDNESDAY...APPROACHING 100 DEGREES IN A FEW PLACES AS THE LACK OF WIDESPREAD CONVECTION ALLOWS FOR BETTER HEATING. HEAT ADVISORIES MAY NEED TO BE CONSIDERED BY FUTURE SHIFTS FOR WEDNESDAY. && .LONG TERM...(THURSDAY THROUGH MONDAY). THE LOCAL AREA RESIDES IN THE BACKSIDE OF THE LONGWAVE TROUGH JUST OFF THE SE CONUS AT THE BEGINNING OF THE EXTENDED PERIOD. BOTH THE 12Z EURO AND LATEST GFS SHOW A MUCH DRIER AIRMASS FILTERING IN ON DEEP LAYER NORTH TO NORTHWEST FLOW WEDNESDAY NIGHT/EARLY THURSDAY. AS THE TROUGH DEAMPLIFIES THURSDAY...THE EURO SHOWS HIGH PRESSURE TO THE WEST BRIDGING ACROSS THE GULF TO JOIN THE SUBTROPICAL RIDGE TO OUR EAST. THIS RIDGING HOLDS THROUGH SATURDAY BEFORE A SHARP TROUGH DIGS DOWN FROM THE NORTH SUNDAY THROUGH MONDAY. THE GFS SHOWS THE HIGH TO OUR WEST BRIEFLY BUILDING INTO THE AREA THURSDAY BUT KEEPS THE TRI-STATE REGION IN OR CLOSE TO THE WEAKNESS BETWEEN THE TWO RIDGES FRIDAY AND SATURDAY BEFORE A PRONOUNCED TROUGH TO OUR NORTH DIGS AND BECOMES ESTABLISHED SUNDAY AND MONDAY. WILL BLEND SOLUTIONS AND SHOW THURSDAY AND FRIDAY WITH BELOW SEASONAL POPS (20-30%) ALONG WITH HOT AFTERNOON TEMPS. BOTH MODELS SUPPORT UNSETTLED CONDITIONS WITH NEAR SEASONAL POPS (30-40%) AND NEAR NORMAL TEMPS TO FINISH UP THE EXTENDED PERIOD. && .MARINE...WINDS AND SEAS WILL CONTINUE THEIR SLOW RISE AS THE PRESSURE GRADIENT BEGINS TO INCREASE ACROSS THE MARINE AREA. WITH WINDS AND SEAS ALREADY AT 15 KNOTS AND THE OCCASIONAL 4 FOOT SEA REPORT...DON'T SEE MUCH REASON WHY WE WON'T BE AT CAUTIONARY CONDITIONS OVERNIGHT FOR ALL BUT THE EASTERN LEGS. AS A RESULT...WILL INTRODUCE AN SCEC HEADLINE OVERNIGHT. THIS MAY DIMINISH BY TUESDAY AFTERNOON...BUT THE MODELS ALL SHOW A FURTHER TIGHTENING OF THE GRADIENT ON TUESDAY NIGHT...LEADING TO A PERIOD OF SCEC CONDITIONS WITH AN OUTSIDE SHOT AT ADVISORY CONDITIONS. WINDS WILL BEGIN A DECREASING TREND ON WEDNESDAY AFTERNOON CONTINUING INTO THE REMAINDER OF THE WEEK WHEN A MORE TYPICAL SUMMERTIME PATTERN WILL RETURN. && .AVIATION...A SCT CU FIELD ALONG WITH SCT SHRA AND TSRA ARE DEVELOPING THIS AFTERNOON. SO FAR MOST OF THE ACTIVITY HAS BEEN CONFINED TO MAINLY THE FLORIDA PANHANDLE AND BIG BEND BUT A FEW STORMS COULD ALSO DEVELOP IN SOUTHEAST ALABAMA AND SOUTHWEST AND SOUTH CENTRAL GEORGIA THROUGH THE REMAINDER OF THE AFTERNOON. ANY STORM WHICH MOVES OVER A TERMINAL COULD TEMPORARILY DROP VIS/CIGS TO MVFR/IFR LEVELS BUT VFR CONDITIONS WILL OTHERWISE PREVAIL. THIS ACTIVITY IS EXPECTED TO DIMINISH QUICKLY AFTER SUNSET. SOME PATCHY MVFR VIS IS POSSIBLE LATE TONIGHT. && .FIRE WEATHER...ABUNDANT LOW LEVEL MOISTURE IS EXPECTED TO KEEP RELATIVE HUMIDITY VALUES ABOVE CRITICAL LEVELS THROUGH THE WEEK. && .PRELIMINARY POINT TEMPS/POPS...

WESTERLY WINDS WILL BE INCREASING ACROSS THE NORTHEAST GULF OF MEXICO THROUGH TONIGHT. THESE WINDS WILL APPROACH CAUTIONARY LEVELS AT TIMES...ESPECIALLY TONIGHT. THE INCREASING WINDS WILL ALSO INCREASE THE WESTERLY SWELL INTO THE FLORIDA PANHANDLE.
