The episode as NWS JAX wrote it up.
A surface ridge axis was across south Florida with broad troughing over south Georgia. A short wave trough was moving east over the Gulf Coast region with a swath of drier air over south Georgia. In addition, temperatures aloft decreased which assisted in destabilization. A moist airmass and slow storm motion produced areas of heavy rainfall across north Florida in the evening.
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 Jacksonville, FL wrote its last area forecast discussion before the first event at Aug 26, 2:05 PM EST, 3 hours 25 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE JACKSONVILLE FL 305 PM EDT THU AUG 26 2010 ...RECORD STREAK OF 90 DEGREES CONTINUES AT JAX AND AMG... .SHORT TERM...LATEST MSAS ANALYSIS CONTINUES TO SHOW HIGH PRESSURE AT THE SURFACE ANCHORED OVER SOUTH CENTRAL FLORIDA WITH A SUBTLE WAVE NOTED OVER SOUTH FLORIDA AND THE KEYS. RIDGE WITHIN THE LAST SEVERAL HOURS HAS ACTUALLY NOSED NORTHWARD ALONG THE WESTERN PERIPHERY INTO THE EASTERN GULF ALLOWING...LIKELY THE CULPRIT IN DECREASED SHOWER AND THUNDERSTORM ACTIVITY THUS FAR TODAY. MODELS STILL SHOW SHORTWAVE ACTIVITY POISED IN THE GULF AND WATER VAPOR CONFIRMS THIS...SO EXPECT AN INCREASE IN PRECIP COVERAGE THROUGH THIS EVENING WITH ITS APPROACH. IN ADDITION...WITH EAST COAST SEABREEZE DEVELOPMENT AND SLIGHTLY HIGHER INSTABILITY ALONG THE COAST...SCT STORMS SHOULD DEVELOP. WHERE THESE VARIOUS FEATURES COINCIDE WILL BE WHERE HIGHEST POPS RESIDE AND FEEL THIS WILL BE ALONG AND WEST OF THE I95 CORRIDOR MAINLY SOUTH OF JAX. WILL STILL BE MONITORING GA PORTION AS WELL AS TEMPS ALOFT ARE COLDER THAN THE PAST MONTH OR SO WITH -7C. MORE SUNSHINE THERE AND INCREASED INSTABILITY SHOULD BE THE IMPETUS FOR ADDITIONAL SCT STORMS. DRY AIR ALOFT COULD AID IN DEVELOPMENT OF A FEW STRONG STORMS WITH WET MICROBURSTS. FOR FRIDAY...MOISTURE AXIS REMAINS ACROSS THE AREA WITH MID AND UPPER LEVEL HIGH REMAINING WELL TO THE SOUTH. CHALLENGE WILL BE IDENTIFYING INDIVIDUAL SHORTWAVES THAT EMANATE FROM THE EASTERN GULF. FOR NOW...WILL USE A A SIMILAR POP PROFILE TO TODAYS WITH THE EXCEPTION BEING LOWER POPS OVER SOUTHEAST GEORGIA AND ALONG THE ATLANTIC COAST AS DRY AIR WORKS DOWN THE COAST. DRIER AIR AT THE SURFACE AS WELL SHOULD LIMIT INSTABILITY WITH ONLY ISOLATED THUNDERSTORMS AT BEST EXPECTED. REGARDLESS OF ACTUAL POP OUTCOME...IT LOOKS AS THOUGH ABUNDANT CLOUD COVER WILL BE PRESENT AND WITH DEVELOPING NORTHEAST FLOW EARLIER...JAX RECORD 90 DEGREE STREAK COULD BE IN JEOPARDY. SAT LOOKS TO BE A TRANSITION DAY AS SURFACE HIGH BECOMES ENTRENCHED OVER THE CAROLINAS WITH WEDGING DOWN THE ATLANTIC COAST...PROVIDING FOR A NORTHEAST FLOW REGIME FOR OUR AREA. QUESTIONS ALWAYS ARISE DURING THIS REGIME WHETHER COASTAL SHOWERS WILL BE THE RULE OR IT BECOMES MORE OF A TYPICAL INLAND CONVERGENCE DAY AS THE EAST COAST SEABREEZE MARCHES ACROSS. FOR NOW...WILL PLAY IT AS SHOWERS IN THE MORNING ALONG THE COAST WITH GREATEST COVERAGE INLAND DURING THE AFTERNOON. DRIER AIR SHOULD WORK INTO THE GA ZONES FOR SUN WITH MAIN FOCUS SOUTH OF THE I10 CORRIDOR. && .CLIMATE... WILL BE A CLOSE CALL ON STREAK FOR FRIDAY...BUT MORE LIKELY TO GET BROKEN BY COOLER AIR BEHIND BACK DOOR COLD FRONT FOR THE WEEKEND. .LONG TERM...MONDAY THROUGH WEDNESDAY...

GUSTY WINDS AND FREQUENT LIGHTNING WILL BE POSSIBLE IN THUNDERSTORM ACTIVITY THIS AFTERNOON AND EVENING. MAXIMUM TEMPERATURES IN THE LOWER TO MID 90S ALONG THE I-10 CORRIDOR AND NORTHWARD ACROSS SOUTHEAST GEORGIA WILL PUSH HEAT INDICES INTO THE 100 TO 105 DEGREE RANGE THIS AFTERNOON. .DAYS TWO THROUGH SEVEN...FRIDAY THROUGH WEDNESDAY...
