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 Jul 10, 1:47 PM EST, 2 hours 58 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE TALLAHASSEE FL 247 PM EDT SUN JUL 10 2011 .SYNOPSIS... THE 18 UTC REGIONAL SURFACE ANALYSIS SHOWED A QUASI-STATIONARY FRONTAL SYSTEM FROM THE SC COAST...THROUGH CENTRAL GA...AND UP THROUGH WESTERN TN. SCATTERED THUNDERSTORMS HAVE DEVELOPED ALONG THE WARM SIDE OF THIS FRONT. ELSEWHERE...STORMS HAVE BEEN MUCH MORE ISOLATED ACROSS OUR AREA...MAINLY ALONG THE SEA BREEZE FRONT. VAPOR IMAGERY AND UPPER AIR DATA SHOWED A BROAD AREA OF HIGH PRESSURE OVER MUCH OF THE EASTERN AND CENTRAL CONUS. THERE WAS A VORT MAX OFF THE FL EAST COAST...WHERE THE BASE OF THE TROUGH PINCHED OFF FROM THE WESTERLIES. && .SHORT TERM... (TONIGHT THROUGH WEDNESDAY) DESPITE THE EXPECTED RIDGING AT 500 MB OVER MUCH OF THE SOUTHEAST...THE WEATHER PATTERN OVER OUR FORECAST AREA WILL BE RATHER UNSETTLED AS WE WILL BE SOUTH OF THIS HIGH...AND THERE WILL BE AMPLE DEEP LAYER MOISTURE AS PRECIP WATER VALUES ARE FORECAST TO REMAIN ABOVE CLIMATOLOGY. THUS WE EXPECT OUR POP TO BE NEAR OR ABOVE CLIMATOLOGY THROUGH THE FORECAST PERIOD. ALTHOUGH THE HIGHEST RAIN CHANCES WILL BE DURING THE AFTERNOON AND EVENING HOURS (AS IS TYPICAL OF SUMMER)...RAIN CHANCES WILL BE ABOVE AVERAGE EVEN DURING THE OVERNIGHT HOURS...AS THERE MAY BE PERIODS OF Q-G FORCING FROM UPPER LEVEL DISTURBANCES APPROACHING FROM THE EAST (SOUTH OF THE RIDGE). THE FIRST OF THESE DISTURBANCES (CURRENTLY OFF THE NORTHEAST FL COAST) WILL COME TONIGHT AND MONDAY. THE MOS CONSENSUS FORECASTS HIGH TEMPERATURES TO BE ABOVE AVERAGE (WELL INTO THE MID 90S INLAND)...DESPITE THE FAIRLY HIGH RAIN CHANCES. WHEN COMBINED WITH THE VERY HUMID AIRMASS...HEAT INDEX VALUES COULD EXCEED 105 DEGREES IN SOME AREAS BEGINNING MONDAY AFTERNOON. WHILE THIS MAY WARRANT A HEAT ADVISORY ON SUBSEQUENT FORECAST PACKAGES...IT IS STILL UNCLEAR HOW WIDESPREAD THESE HIGH HEAT INDEX VALUES WILL BE GIVE THE EXPECTED CLOUD COVER AND THUNDERSTORM ACTIVITY. .LONG TERM... (WEDNESDAY NIGHT THROUGH NEXT SUNDAY) THE LARGE SCALE PATTERN ACROSS THE CONUS WILL CONTINUE TO EVOLVE AS ADVERTISED IN PREVIOUS FORECASTS...WITH A MEAN TROUGH NEAR THE WEST COAST...ANOTHER TROUGH JUST OFF THE EAST COAST...AND STRONG RIDGING IN BETWEEN. THE LARGE SCALE PATTERN WILL REMAIN ABNORMALLY AMPLIFIED FOR THIS TIME OF YEAR...AND THERE ARE INDICATIONS THAT A SLOW RETROGRESSION WILL BEGIN TO TAKE PLACE TOWARD THE END OF THIS WEEK. AT THE BEGINNING OF THE PERIOD...THE RIDGE WILL BE CENTERED OVER THE TENNESSEE VALLEY...BUT AS A STRONG SHORT WAVE DIGS INTO THE WEST COAST TROUGH AND CAUSES THE PATTERN TO AMPLIFY DOWNSTREAM...THE CENTER OF THE RIDGE WILL SHIFT WEST AND THEN NORTH AWAY FROM THE TRI-STATE AREA. THIS WILL SET THE STAGE FOR AN ABNORMALLY VIGOROUS SHORT WAVE TO DROP INTO THE TROUGH OFF THE EAST COAST ON THURSDAY AND FRIDAY...FOLLOWED CLOSELY BY ANOTHER ONE ON SUNDAY...WHICH WILL DROP SOUTHWARD FURTHER TO THE WEST...AS A RESULT OF THE SLOW WESTWARD SHIFT TAKING PLACE IN THE LARGE SCALE. DURING THE COMING WEEK...THE AREA WILL CONTINUE TO BE DOMINATED BY DEEP LAYER TROPICAL MOISTURE...KEPT IN PLACE BY A WEAK SOUTHERLY FLOW AROUND THE WESTERN ATLANTIC SUBTROPICAL RIDGE. STRONG DAYTIME HEATING AND THE DIURNAL SEABREEZE WILL PROVIDE AMPLE SUPPORT FOR SCATTERED AFTERNOON AND EARLY NIGHTTIME SHOWERS AND THUNDERSTORMS EACH DAY. AS THE SERIES OF SHORT WAVES DROPS INTO THE TROUGH OFF THE EAST COAST THURSDAY THROUGH SUNDAY...PRESSURES AND TEMPERATURES WILL DECREASE AT UPPER LEVELS OVER THE AREA...AND A FRONTAL BOUNDARY WILL PUSH SOUTH AND WEST FROM THE CAROLINAS INTO GEORGIA...WHICH SHOULD PROVIDE ADDITIONAL SUPPORT FOR AN INCREASE IN CLOUDS...SHOWERS AND THUNDERSTORMS ACROSS THE AREA BY THE WEEKEND. TEMPERATURES WILL START OUT ABOVE NORMAL AND TREND DOWNWARD TO NEAR NORMAL BY THE WEEKEND. POPS WILL REMAIN NEAR OR A LITTLE ABOVE CLIMATOLOGICAL NORMALS...HOPEFULLY CONTINUING TO TAKE AT LEAST SMALL BITES OUT OF THE ONGOING DROUGHT. && .AVIATION... DEEP LAYER TROPICAL MOISTURE AND UNSTABLE AIR CONTINUES TO SETUP THE POTENTIAL FOR SCATTERED THUNDERSTORMS ACROSS THE ENTIRE AREA THIS AFTERNOON WITH VSBYS DROPPING TO 2NM IN LOCALLY HEAVY RAINFALL. CURRENTLY A LINE OF STORMS ARE DROPPING SOUTH ACROSS SOUTHWEST GEORGIA THAT WILL AFFECT KABY SHORTLY. KDHN WILL BE NEXT...THEN KVLD. MEANWHILE THUNDERSTORMS ARE DEVELOPING RAPIDLY ALONG A SEA BREEZE FRONT THAT IS MOVING INLAND FROM COASTAL FRANKLIN...WAKULLA...JEFFERSON AND TAYLOR COUNTIES. THE SEA BREEZE STORMS WILL MOVE INTO THE KTLH AERODROME WITHIN THE HOUR. JUST UPDATED ALL THE TAFS TO REFLECT THE ABOVE. CONVECTION SHOULD AGAIN DIMINISH FAIRLY RAPIDLY AFTER SUNSET. WITH THE PRECIPITATION...EXPECT REDUCED VSBYS RANGING FROM VLIFR TO IFR AGAIN TOMORROW MORNING AROUND AERODROMES THAT RECEIVE RAINFALL. && .MARINE... WINDS WILL REMAIN OUT OF THE WEST OR SOUTHWEST AT 10 KT OR LESS THROUGH THE WEEK. ISOLATED WATER SPOUTS WILL BE POSSIBLE...MAINLY DURING THE MORNING AS THAT IS THE CLIMATOLOGICAL PEAK FOR OFFSHORE CONVECTION. && .FIRE WEATHER... WARM AND HUMID CONDITIONS WILL CONTINUE INTO THE NEW WORK WEEK. SCATTERED SHOWERS AND THUNDERSTORMS EACH DAY MAY HELP MITIGATE THE RECENT DRY CONDITIONS. && .PRELIMINARY POINT TEMPS/POPS...
