The episode as NWS TAE wrote it up.
An isolated severe thunderstorm developed with northwest flow aloft and an unstable air mass.
The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Tallahassee, FL wrote its last area forecast discussion before the first event at Aug 22, 1:20 PM CST, 1 hour 50 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE TALLAHASSEE FL 320 PM EDT MON AUG 22 2011 .SYNOPSIS...18 UTC SURFACE ANALYSIS SHOWS A COLD FRONT MOVING THROUGH THE SOUTHEAST. THE BOUNDARY IS ANALYZED JUST SOUTH OF I-20 ACROSS MIDDLE GEORGIA INTO MID STATE SOUTH CAROLINA. OUT AHEAD OF THIS BOUNDARY WAS A WEAK CONFLUENCE ZONE...ROUGHLY ACROSS OUR NORTHERN COUNTIES. IT IS IN THIS AREA THAT SCATTERED SHOWERS AND THUNDERSTORMS ARE DEVELOPING. SURPRISINGLY...THE SEA BREEZE FRONT TODAY HAS NOT BEEN VERY ACTIVE...DESPITE THE ENHANCED CONVERGENCE. IT APPEARS THAT THE DRIER AIR ALOFT IS WINNING OUT...BASED ON OUR 18Z SOUNDING WHICH IS SHOWING NOT ONLY DRYING ALOFT BUT WARMER TEMPERATURES IN THE 500-300 MB LAYER. && .SHORT TERM...(TONIGHT THROUGH WEDNESDAY NIGHT). OVERALL...THE SHORT TERM MODELS ARE IN PRETTY GOOD AGREEMENT THAT THE SURFACE BOUNDARY WILL DROP TOWARD THE GULF COAST THIS EVENING BEFORE STALLING AND DISSIPATING. DRIER AIR ALOFT WILL CONTINUE TO RESULT IN LESS RAINFALL CHANCES THROUGHOUT THE SHORT TERM PERIOD. GRADUALLY INCREASING MOISTURE FROM THE EAST ON WEDNESDAY WILL LIKELY LEAD TO A SLIGHT ENHANCEMENT IN RAIN CHANCES FOR THE EASTERN AREA IN MODERATE EASTERLY FLOW. TEMPERATURES THROUGHOUT THE PERIOD WILL CONTINUE TO BE WARM...TEMPS GENERALLY PEAKING IN THE MID TO UPPER 90S ACROSS THE REGION. GENERALLY STAYED A COUPLE DEGREES ABOVE GUIDANCE THROUGHOUT THE PERIOD AS LESSER RAIN CHANCES SHOULD SUPPORT BETTER AFTERNOON HEATING. && .LONG TERM...(THURSDAY THROUGH NEXT MONDAY). UPDATED LONG TERM DISCUSSION...3 PM ET. THE LATEST NATIONAL HURRICANE CENTER FORECAST FOR IRENE HAS CONTINUED TO SHIFT EASTWARD THROUGHOUT THE DAY. THIS TREND IS ALSO APPARENT IN MOST OF THE GUIDANCE MEMBERS. THIS EASTWARD SHIFT WOULD RESULT IN LIGHTER WINDS ACROSS THE FORECAST AREA. AS A RESULT...ADJUSTED THE WIND GRIDS DOWN SLIGHTLY THROUGHOUT THE EXTENDED PERIOD TO MATCH WITH THE LATEST FORECAST. OF COURSE...WE WILL NEED TO CONTINUE TO WATCH IRENE CLOSELY...AS FEATURES JUST NOW MOVING INTO THE WESTERN CONUS WILL BE AFFECTING ITS NORTHWARD TURN LATER THIS WEEK. STAY TUNED AND CONTINUE TO MONITOR THE LATEST FORECASTS FROM THE NATIONAL HURRICANE CENTER. PREVIOUS OVERNIGHT LONG TERM DISCUSSION FROM 330 AM ET BELOW. THE FOCUS FOR THE LONG TERM CONTINUES TO BE ON IRENE AND WHAT EFFECTS...IF ANY...IT WILL HAVE ON THE LOCAL AREA. AS IRENE APPROACHES THE SOUTHEAST U.S. BY THE END OF THE WEEK...THE UPPER LEVEL PATTERN IS FORECAST TO BE SETUP WITH RIDGING OVER THE WESTERN STATES AND TROUGHING OVER THE GREAT LAKES REGION WITH A SUBTROPICAL RIDGE OVER THE WESTERN ATLANTIC. THE TROUGHING OVER THE GREAT LAKES IS EXPECTED TO PROVIDE A BREAK IN BETWEEN THE ATLANTIC SUBTROPICAL RIDGE AND THE RIDGE OVER THE WESTERN STATES THAT WILL PLAY AN IMPORTANT ROLE IN THE FUTURE PATH OF IRENE. THE BIGGER THAT BREAK IS IN BETWEEN THE TWO RIDGES...THE MORE LIKELY IT BECOMES THAT IRENE WILL TURN NORTHWARD AT AN EARLIER TIME AND REMAIN EAST OF THE LOCAL AREA. HOWEVER...IF THE TROUGH TURNS OUT TO BE WEAKER AND RIDGING BUILDS BACK IN MORE QUICKLY NORTH OF THE STORM...THEN IT BECOMES MORE LIKELY THAT IRENE WILL CONTINUE WESTWARD FOR A LONGER PERIOD OF TIME. MODEL SOLUTIONS OVER THE LAST COUPLE OF DAYS HAVE STARTED TO CONVERGE ON A MORE EASTWARD TRACK TO THE EAST OF THE FORECAST AREA NEAR THE EAST COAST OF FLORIDA...AND THE OFFICIAL NHC FORECAST AGREES. IF THE EASTWARD TRACK VERIFIES...SOME BREEZY NORTHERLY WINDS AND AN INCREASED CHANCE OF RAIN WOULD OCCUR ACROSS THE EASTERN PARTS OF THE FORECAST AREA...BUT THE MAJOR IMPACTS WOULD STAY EAST OF THE AREA. A COUPLE OF MODELS SUCH AS THE 22/00Z UKMET AND 22/00Z GFDL ARE STILL FARTHER TO THE WEST...BUT THEY ARE CONSIDERED OUTLIERS AND LESS LIKELY SOLUTIONS AT THE MOMENT. AT THIS STAGE...IT IS IMPORTANT TO REMEMBER THAT THE DAY 5 TROPICAL CYCLONE FORECASTS CARRY A 5 YEAR AVERAGE TRACK ERROR OF AROUND 250 MILES AND A 5 YEAR AVERAGE INTENSITY ERROR OF AROUND 20 KNOTS. THEREFORE...EVEN THOUGH THE CONSENSUS OF THE GUIDANCE IS NOT SHOWING A MAJOR IMPACT FOR OUR FORECAST AREA AT THIS TIME...IT REMAINS A GOOD IDEA TO CONTINUE MONITORING THE SYSTEM CLOSELY AS A WESTWARD SHIFT IN TRACK WOULD INCREASE THE THREAT LOCALLY. PLEASE REFER TO THE NHC ADVISORIES FOR THE LATEST INFORMATION ON THE FORECAST TRACK AND INTENSITY OF IRENE. && .MARINE...EXPECT LIGHT WINDS AND LOW SEAS FOR THE BALANCE OF THE SHORT TERM PERIOD. AS IRENE APPROACHES THE SOUTHEAST U.S. COAST...THE PRESSURE GRADIENT WILL TIGHTEN. BASED ON THE LATEST FORECAST...WINDS ARE EXPECTED TO APPROACH LOW-END ADVISORY LEVELS THURSDAY NIGHT INTO FRIDAY...PRIMARILY ACROSS THE EASTERN LEGS. IF IRENE MOVES CLOSER THAN EXPECTED...THE WINDS WILL BE STRONGER THAN CURRENTLY INDICATED IN THE FORECAST. ALL INTERESTS IN THE EASTERN GULF OF MEXICO...SHOULD KEEP UP TO DATE WITH THE LATEST FORECASTS CONCERNING IRENE. && .AVIATION...THUNDERSTORMS BEGINNING TO DEVELOP PER AREA RADARS AND VISIBLE SATELLITE IN A WEAK CONVERGENCE ZONE FROM SRN AL INTO S/C GA...APPROXIMATELY 10-20 MI NORTH OF THE ABY AND DHN TERMINALS. SHORT RANGE MODEL GUIDANCE AND ENSEMBLES SUGGEST THAT THIS ACTIVITY WILL CONTINUE TO DEVELOP AND IMPACT ABY AND DHN EARLY-MID AFTN. THEREFORE...A TEMPO GROUP WAS INTRODUCED AT BOTH THOSE TERMINALS. BEST CHC FOR TSTMS OUTSIDE OF THOSE AREAS LOOKS TO BE AT TLH. WENT WITH A TEMPO GROUP THERE...WITH ONLY A CB MENTION AT VLD AND ECP. THERE COULD BE SOME LOCALIZED GUSTY WINDS WITH ANY STRONGER STORM. CONFIDENCE IN FOG POTENTIAL TONIGHT IS LOW...ESPECIALLY WITH DRIER AIR MASS BEGINNING TO WORK INTO THE AREA AFTER 09Z. HINTED AT SOME 6SM VSBYS WITH BR AT TLH...ECP...AND VLD BETWEEN 10Z AND 13Z...BUT DID NOT INTRODUCE ANY MVFR RESTRICTIONS FOR NOW. && .FIRE WEATHER...NO CRITICAL CONDITIONS ARE EXPECTED IN THE FORESEEABLE FUTURE. DRIER AIR MASS ARRIVING TOMORROW SHOULD DROP MIN RH VALUES IN ALABAMA ZONES AND FAR SW GEORGIA ZONES CLOSE TO THE 30-35 PERCENT RANGE. HOWEVER...THE RH VALUES SHOULD ONLY APPROACH CRITICAL THRESHOLDS FOR AN HOUR OR SO. COMBINED WITH LIGHT WINDS THIS SHOULD KEEP ALL OF OUR AREAS OUT OF RED FLAG CONCERNS. && .PRELIMINARY POINT TEMPS/POPS...
