The episode as NWS JAX wrote it up.
A stalled front, passing upper level short wave trough from the Gulf of Mexico, high moisture and instability phased over NE Florida and SE Georgia which yielded scattered strong storms and locally heavy rainfall.
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 Oct 8, 1:35 PM EST, 2 hours 25 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE JACKSONVILLE FL 235 PM EDT MON OCT 8 2012 .NEAR TERM...CONSIDERABLE HIGH CLOUDS...FROM AN MCS IN THE NE GULF...HAS DELAYED THE DAYTIME HEATING AND ONSET OF NUMEROUS SHOWERS/STORMS OVER THE AREA. ISOLATED STORMS WERE DEVELOPING ALONG THE SE GA COASTS WHERE A BROAD SURFACE LOW WAS. THERE HAS BEEN ROTATION ALOFT IN SOME OF THESE STORMS. THERE WERE SCATTERED SHOWERS/ STORMS BOTH IN THE ATLANTIC AND NE GULF IN ASSOCIATION WITH BROAD LOW PRESSURE AREAS. THE ACTIVITY WAS MOVING SLOWLY NORTHEAST. MEANWHILE...A FRONTAL BOUNDARY REMAINED NEARLY STATIONARY ACROSS NE FL FROM AROUND A JAX TO LIVE OAK LINE. MORE COOLER AND STABLE BEHIND THIS FRONT WITH CONSIDERABLE LOW CLOUDS THAT WERE SLOWLY LIFTING. AS A SHORT WAVE MOVES IN FROM THE GULF LATE THIS AFTERNOON IT WILL INTERACT WITH THE FRONT AND STILL EXPECTING A ROUND OF SCATTERED TO NUMEROUS SHOWERS/STORMS. THE RIGHT REAR QUADRANT OF THE SUBTROPICAL JET WILL ALSO BE MOVING THROUGH WHICH MAY HELP ENHANCE STORMS. A FEW STORMS MAY STILL BE STRONG...ESPECIALLY ACROSS THE FAR SOUTHERN AND SE ZONES WHERE THERE WILL BE LESS HIGH CLOUD COVER AND BETTER HEATING. WILL STILL KEEP MENTION OF ISOLATED STORMS ACROSS SE GA DUE TO THE STRONG UPPER DYNAMICS THAT MAY OVERCOME THE SURFACE BASED STABILITY...BUT BEST COVERAGE WILL BE ALONG AND SE OF THE FRONTAL BOUNDARY. .SHORT TERM... TONIGHT...WILL KEEP CHANCE POPS ACROSS THE EASTERN PORTION OF NE FL INTO THE EARLY EVE AS THE SHORT WAVE MOVING IN FROM THE GULF INTERACTS WITH THE FRONTAL BOUNDARY. AFTER THE PASSAGE OF THE SHORT WAVE...THE COLD FRONT WILL SWING SE OUT OF THE AREA AND WILL SEE AN END TO THE SHOWER/TSTM ACTIVITY. HOWEVER...MODELS AND MODEL SOUNDINGS INDICATE CONSIDERABLE LOW CLOUDS MOVING IN AREA WIDE BY LATE THIS EVE AND OVERNITE...BEHIND FRONT...AS LOW BASED INVERSION SETS IN ALONG WITH WEAK ISENTROPIC LIFT. WILL ALSO MENTION PATCHY FOG ACROSS THE FAR SOUTHERN ZONES WHERE BOUNDARY LAYER WINDS THERE WILL BE WEAKER. WILL HAVE A SHARP NW-SE TEMP GRADIENT BEHIND FRONT WITH MIN TEMPS RANGING FROM THE MID/UPPER 50S ACROSS SE GA TO THE MID/UPPER 60S) ACROSS THE FAR SE ZONES. TUESDAY/TUESDAY NIGHT...THE LOW CLOUDS WILL PERSIST INTO TUESDAY AND THEN BEGIN TO LIFT ACROSS SE GA BY EARLY AFTERNOON AND ELSEWHERE BY MID/LATE AFTERNOON. HIGH PRESSURE BUILDS INTO THE REGION...WITH THE FRONTAL BOUNDARY GETTING A PUSH INTO CENTRAL FLORIDA.

HIGH TEMPERATURES TUESDAY WILL BE 3-5 DEGREES COOLER THAN MONDAY...WITH LOWS NEAR 60 AS FAR SOUTH AS INTERIOR SECTIONS OF NE FL TUESDAY NIGHT. .LONG TERM.../WEDNESDAY THROUGH SUNDAY/... SURFACE HIGH PRESSURE OVER THE SOUTHEASTERN STATES WILL BE REINFORCED BY ANOTHER SURFACE RIDGE MIGRATING EASTWARD ACROSS THE TENNESSEE VALLEY...AS OUR FLOW ALOFT BRIEFLY BECOMES NORTHWESTERLY. THIS WEATHER PATTERN WILL KEEP A SEASONABLY COOL AND DRY AIR MASS IN PLACE THROUGH EARLY FRIDAY...WITH HIGHS GENERALLY BETWEEN 80 AND 85 AND LOWS RANGING FROM THE UPPER 50S OVER INTERIOR SOUTHEAST GEORGIA TO THE UPPER 60S ALONG THE IMMEDIATE COAST. BROAD TROUGHING ALOFT OVER THE EASTERN UNITED STATES WILL LIFT NORTHEASTWARD LATE IN THE WEEK...WITH RIDGING ALOFT EXPANDING OVER OUR AREA FROM THE GULF OF MEXICO. ONSHORE FLOW WILL DEVELOP BY FRIDAY AND GRADUALLY DEEPEN NEXT WEEKEND...RESULTING IN A GRADUAL UPTICK IN TEMPERATURES AND DEWPOINTS TO JUST ABOVE MID OCTOBER CLIMATOLOGY REGION-WIDE. MOISTURE SHOULD REMAIN RELATIVELY SHALLOW THROUGH SATURDAY...AND HAVE LEFT RAIN CHANCES OUT OF THE FORECAST GRIDS UNTIL SATURDAY NIGHT...EXCEPT ISOLATED COVERAGE FOR THE COASTAL WATERS. HAVE PLACED ISOLATED POPS IN THE GRIDS REGION- WIDE FOR THE END OF NEXT WEEKEND AS LONG-TERM GUIDANCE DEPICTS VEERING IN OUR LOW-LEVEL WIND PROFILE IN CONCERT WITH INCREASING DEEP-LAYERED MOISTURE. && .AVIATION...TEMPO GROUPS USED FOR REST OF THE AFTN WITH INCREASED CHANCE OF TSTMS WITH OCNL MVFR TO IFR CIGS/VSBY EXPECTED THROUGH AT LEAST 22Z. CONVECTION SHOULD WIND DOWN IN THE EVENING HOURS WITH VFR CONDS FOR A TIME BEFORE THE COLD FRONT UNDERCUTS MOIST AIR ALOFT AND CREATES STRATUS AND SOME MVFR VSBY RESTRICTIONS. CIGS WILL BE SLOW TO LIFT ON TUESDAY AND HAVE IFR/MVFR CONTINUING INTO LATE MORNING. && .MARINE...E TO SELY WINDS NEAR 10-15 KT AND SEAS OF ABOUT 2-3 FT.
