The episode as NWS JAX wrote it up.
An upper level ridge was west northwest of the area. A pre-frontal surface trough extended from the middle Atlantic State to the Gulf of Mexico Coast. A cold front was across extreme northern Georgia. Storm initiated in the afternoon and evening along the thermal trough in advance of the pre-frontal trough in 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 Jacksonville, FL wrote its last area forecast discussion before the first event at Jul 10, 1:46 PM EST, 4 hours 9 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE JACKSONVILLE FL 246 PM EDT SAT JUL 10 2010 ...SLIGHTLY LOWER MAX TEMPS AND BETTER CHANCES OF RAIN THE NEXT FEW DAYS... .SYNOPSIS...UPPER RIDGE REMAINS W OF THE AREA WITH AMPLIFIED TROF OFF THE ATLC SEABOARD AND A WEAK SHORTWAVE JUST S OF THE AREA. SUBSIDENCE ON BACK SIDE OF THIS SHORTWAVE AND LINGERING DRY AIR HAVE LEFT THE SE 1/2 OF THE AREA UNDER MOSTLY SUNNY SKIES WITH TEMPS PUSHING THRU THE MID 90S OVER E AREAS ON 10 TO 15 KT SW FLOW. CU FIELD IS DEVELOPING IN THE MORE MOIST AIR OVER OUR NW ZONES AHEAD OF A PRE-FRONTAL TROF. TSTMS ARE ALREADY ERUPTING OVER THE FL PANHANDLE WITH ENHANCED CONVECTION EVIDENT INTO THE KAMG AND KDQH AREAS. .SHORT TERM...EXPECT TSTMS TO CONTINUE TO DEVELOP OVER OUR NW ZONES AND PUSH E. TALLER STORMS MAY MOVE A BIT MORE SE LATER IN THE DAY. WINDS ACROSS COASTAL SE GA ARE A BIT STRONGER OUT OF THE SW THAN EXPECTED...AND THIS WILL LIKELY REDUCE THE THREAT OF INCREASED LOW-LEVEL CONVERGENCE IN THAT AREA WITH MORE S FLOW. STILL LOOKS LIKE THE BEST CHANCES OF PRECIP WILL BE OVER INTERIOR SE GA AND THE N SUWANNEE VALLEY WITH POPS DROPPING OFF TO ISOLD AT BEST OVER THE SE ZONES. ANY STORMS THAT DEVELOP OVER NE FL AWAY FROM THE SUWANNEE VALLEY WILL LIKELY BE LATE IN THE AFTN OR PERHAPS IN THE EVENING...PARTICULARLY IF ANY OUTFLOW FROM THE N CAN MAKE IT ACROSS THE STATE LINE. TODAY IS A TRANSITION DAY INTO A PERIOD OF MORE NUMEROUS SHOWER AND TSTM ACTIVITY THAT WILL PEAK SUN AND MON. COVERAGE WILL BE SCATTERED TO NUMEROUS AND FAVOR THE AFTN AND EVENING HOURS ALTHO THE SFC TROF AND WEAKENING COLD FRONT WILL PROVIDE ADDITIONAL IMPETUS. AS A RESULT OF THE DECREASING THICKNESSES...INCREASED CLOUDS AND PRECIP...TEMPS WILL RETURN TO NEAR NORMAL IN MOST AREAS. HOWEVER...WITH CONTINUED SW GRADIENT FLOW...ANY AREAS THAT ESCAPE RAIN AND HAVE A FEW HOURS OF SUN COULD STILL REACH THE MID 90S. MOS TEMPS ARE IN GOOD AGREEMENT AND A BLEND WAS USED. FOG WILL BE PATCHY AND GENERALLY LIGHT WITH THE BEST CHANCES NEAR THE STALLED FRONTAL BOUNDARY AND NEAR RECENT RAIN AREAS. .LONG TERM...THE PRECIP PATTERN WILL RETURN TO A MORE PURE DIURNAL PATTERN WITH TEMPS A FEW DEGREES ABOVE NORMAL. A WEAK HIGH PRESSURE RIDGE WILL REMAIN OVER THE AREA WITH MOSTLY ZONAL FLOW TO THE N. && .AVIATION...HAVE ONLY VCTS IN SSI TAF AFTER 20Z AS MOST ACTIVITY TO REMAIN OVER INTERIOR SE GA THIS AFTERNOON. SLOW MOVEMENT TO THE SOUTHEAST MAY PUSH ANY REMAINING STORMS CLOSER TO TAF SITES TONIGHT. MAY HAVE TO INCLUDE TS IN FORECAST WITH NEXT TAF ISSUANCE. && .MARINE...SW FLOW TO CONTINUE WITH NIGHTLY WIND SURGE EXPECTED AGAIN. HAVE SEPARATED NEAR AND OFFSHORE ZONES WITH HIGHER WIND SPEEDS EXPECTED OFFSHORE. MAY COME CLOSE TO SCEC WIND CRITERIA FOR OFFSHORE WATERS. NO HEADLINES FOR NOW. && .FIRE...BRIEF RH'S AOB 35 PERCENT AGAIN TODAY OVER NE FL DUE TO HOT TEMPERATURES AND DRY AIR MIXING DOWN.
