The episode as NWS JAX wrote it up.
Short wave trough energy combined over a moist and unstable airmass across north and central Florida to yield scattered severe storms.
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 Jul 3, 8:45 AM EST, 4 hours 33 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE JACKSONVILLE FL 945 AM EDT FRI JUL 3 2009 .UPDATE...WATER VAPOR IMAGERY CONTINUES TO SHOW LONG WAVE TROUGH OVER THE ERN U.S. WITH UPPER LEVEL LOW JUST N OF NY AND THE TROUGH AXIS EXTENDING SWD INTO SC AND INTO THE NE GULF OF MEXICO. DEEPEST MOISTURE CONTS JUST S OF THE FORECAST AREA YET THE JAX AND TAE 12Z SOUNDINGS SHOW PWATS OF NEAR 1.8 INCHES...UP ABOUT 3 TENTHS FROM YESTERDAY. MOST OF THE MOISTURE INCREASE WAS BELOW 700MB. SO IF ANYTHING...THE ATMOSPHERE APPEARS MORE UNSTABLE THAN YESTERDAY AND MID LEVELS HAVE DRIED A BIT...MAKING THE DOWNBURST POTENTIAL EVEN GREATER WITH THE STRONGEST OF STORMS. USING PARCEL OF 93/72 YIELDS SBCAPE VALUES AROUND 3K...LI OF -6...MPDI IS OVER 1 AND WINDEX VALUE IS ABOUT 65 KT. CURRENT HWO COVERS THIS WELL. AT THE SFC...A DIFFUSE FRONTAL BOUNDARY APPEARS TO BE OVER THE SC COASTAL WATERS TO INLAND SE GA INTO THE WRN FL PANHANDLE. DEWPOINTS S OF THE BOUNDARY ARE IN THE LOWER TO MID 70S AND WITH PLENTY OF MOISTURE IN THE LOW LEVELS THE CU FIELD SHOULD FORM QUICKLY TODAY OVER OUR FL ZONES. ON RADAR ISOLD SMALL ECHOES ARE APPEARING OVER THE FL BIG BEND. SIMILAR TO YESTERDAY...THERE IS SOME UPPER SUPPORT IN THE FORM OF A SHORTWAVE TROUGH ROTATING THROUGH THE TROUGH OVER GA BUT THE BEST LIFT THIS TIME IS OVER THE FL ZONES THIS AFTERNOON WHICH IS ALSO WHERE THE BETTER MOISTURE RESIDES AS MENTIONED. GIVEN THIS...THE ONGOING FORECAST OF GOING ABOVE GUIDANCE POPS SEEMS REASONABLE. WILL ONLY TWEAK POPS FOR THE MORNING UPDATE BUT BASICALLY SCT COVERAGE OVER FL AND ISOLD OVER GA. MAX TEMPS AGAIN IN THE MID 90S FOR THE MOST PART WITH HEAT INDICES JUST OVER 100. THE WINDS JUST OFF THE SFC ARE STRONGER (20-25 KT) THAN YESTERDAY WHICH SHOULD MIX DOWN GIVEN STRONG DIABATIC HEATING. GUSTS OVER 20 MPH ARE EXPECTED AT TIMES BY MID MORNING AND IN AFTERNOON. THUS...THE E COAST SEA BREEZE WILL BE PINNED NEAR THE COAST LATER TODAY. && .AVIATION...VIS IMAGERY SHOWS LOW CLOUDS CONTINUING JUST N OF THE STATE LINE IN OUR CWA WHICH WILL GRADUALLY DISSIPATE NEXT HOUR OR SO. OTHERWISE...VFR EXCEPT LOWER CONDS EXPECTED IN TSRA. AT THIS TIME WE HAVE TEMPO GROUPS FOR TSRA BEGINNING AROUND 18Z/19Z. THERE IS NO COMPELLING REASON TO CHANGE THIS THINKING. WILL REFINE THESE FORECASTS FOR THE 18Z TAFS WITH MOST LIKELY CHANGE TO DETERIORATE CONDS IN TSRA FOR THE AFTERNOON HOURS AND INCLUDE GUSTY WINDS. WILL PROBABLY NEED TO INCREASE MORE GUSTS IN THE TAFS AS WELL. && .MARINE...W WINDS AT BUOY 41012 CONT AT ABOUT 16G19KT AND SEAS OF 3 FT. THESE WINDS WILL DECREASE WITHIN 2-3 HRS WITH SHIFT TO MORE SWLY DIRECTION. ONLY MINOR TWEAKS TO THE FORECAST EXPECTED. && .PRELIMINARY POINT TEMPS/POPS...
