What happened
The episode as NWS JAX wrote it up.
A broad mean layer trough was over the southeast region with a ridge axis across central Florida. An active southwest flow regime tracked the west coast sea breeze inland during the afternoon where it merged with the east coast in the late afternoon and early evening across eastern Florida. High instability and a passing upper level short wave enhanced a few severe storms.

Area forecast discussion, Aug 28, 1:03 PM EST, 3 hours 42 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE JACKSONVILLE FL 203 PM EDT THU AUG 28 2008 .SHORT TERM...A MEAN LAYER TROF EXTENDS FROM THE OHIO VALLEY INTO THE NE GULF OF MEXICO WHILE A RIDGE IS SOUTH OF THE AREA. THIS PATTERN BEGINS TO WEAKEN FRIDAY AS A RIDGE BUILDS IN FROM THE WESTERN ATLANTIC LATE IN THE DAY. DRIER AND MORE STABLE AIR MASS WILL MOVE INTO THE REGION FROM THE NW FRIDAY AND WILL KEEP A N-S POP DISTRIBUTION WITH BEST CHANCES OVER INLAND NE FL FROM SEABREEZE COLLISIONS. THE NAM IS EVEN DRIER ON SATURDAY WITH PWATS DROPPING TO 1.5 INCHES...BUT THE GFS KEEPS PWATS AROUND 1.8 INCHES AND THAT SEEMS MORE REASONABLE. THE SYNOPTIC FLOW WILL SHIFT TO SOUTHEASTERLY FRIDAY THEN EASTERLY OVER THE WEEKEND AS THE RIDGE DRIFTS NORTHWARD. WITH THE ONSHORE FLOW THE BEST CHANCES FOR PRECIP SAT-SUN WILL BE ALONG THE I-75 CORRIDOR...BUT STILL ONLY A 20-30% CHANCE FOR SATURDAY. DEEP MOISTURE WILL FILTER INTO THE AREA FROM THE SOUTH SUNDAY AND POPS WILL INCREASE TO AT LEAST 40% AND MAY BE RAISED DEPENDING ON HOW CLOSE GUSTAV IS TO THE STATE. .LONG TERM (SUN-THU)...FORECAST IS PREDICATED ON THE PATH GUSTAV TAKES OVER THE GULF OF MEXICO AND HANNA IN THE ATLANTIC. HIGH PRESSURE WILL BUILD OVER THE GREAT LAKES AND PUSH SOUTHWARD ALONG THE ERN SEABOARD RESULTING IN AN ONSHORE FLOW DURING THE WEEK. DRIER AIR AND LOWER THAN NORMAL POPS ARE EXPECTED AS THE MID/UPR HIGH DRIFTS BUILDS OVER THE MID ATLANTIC TUE-THU. ALSO...A TIGHTENING PRESSURE GRADIENT COULD RESULT IN BREEZY CONDITIONS NEAR THE EAST COAST BY MID WEEK. && .AVIATION...MODEL GUIDANCE IN AGREEMENT IN SHOWING A LATE DEVELOPING SEABREEZE ALONG THE EAST COAST WHICH SHOULD CREATE ENOUGH OF A CONVERGENCE BOUNDARY TO PRODUCE LOW END SCATTERED COVERAGE OF SHRA/TSRA. COVERAGE STILL LOOKS LIMITED ENOUGH TO WARRANT CONTINUED VCTS ADVERTISEMENT WITH THE 18Z PACKAGE. MOST SITES SAW SOME MVFR FOG LAST NIGHT AND SIMILAR CONDITIONS SHOULD YIELD SIMILAR RESULTS TONIGHT. && .MARINE...RATHER TRANQUIL CONDITIONS EXPECTED FOR THE NEXT SEVERAL DAYS AS LIGHT WESTERLY FLOW WILL TRANSITION TO EASTERLY WITH THE PASSAGE OF THE SEABREEZE ON FRIDAY. RIDGE BUILDS IN TO THE NORTH AS GUSTAV PASSES WELL TO THE SOUTHWEST...INCREASING THE EASTERLY FLOW ACROSS THE AREA. CONDITIONS WILL REMAIN BELOW ANY FLAG CRITERIA. SWELLS COULD INCREASE TO 4 TO 6 FEET BY THE END OF THE PERIOD DEPENDING ON THE FATE OF HANNA. && .PRELIMINARY POINT TEMPS/POPS...
