The episode as NWS JAX wrote it up.

NWS Jacksonville, FL wrote its last area forecast discussion before the first event at Jul 22, 2:10 PM EST, 17 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE JACKSONVILLE FL 310 PM EDT TUE JUL 22 2008 .SHORT TERM...TONIGHT THROUGH FRIDAY. THE LATEST SATELLITE IMAGERY SHOWS A SHARP MID TO UPPER LEVEL SHORTWAVE SPINNING JUST NORTH OF OUR GEORGIA ZONES. IN FACT...THE LATEST RUC ANALYSIS SHOWS A CLOSED 500MB CIRCULATION ASSOCIATED WITH THIS FEATURE. THIS WAVE IS PROGGED TO EXPAND SOUTH THIS AFTERNOON AND REMAIN INFLUENTIAL THROUGH MUCH OF THE NIGHT. MODERATE TO STRONG INSTABILITY EXISTS ACROSS MUCH OF THE LOCAL FORECAST AREA AND AMPLE MOISTURE RESIDES THROUGH THE COLUMN. THIS WILL SET THE STAGE FOR STRONG AFTERNOON THUNDERSTORMS TO CARRY INTO THE EVENING AND POSSIBLY EVEN AFTER MIDNIGHT. SEVERE THUNDERSTORMS ARE POSSIBLE...ESPECIALLY GIVEN LARGE CAPE DENSITY VALUES AND COLD TEMPERATURES ALOFT. BOTH LARGE HAIL AND DAMAGING WIND GUSTS WILL BE CONCERNS. SLOW STORM MOVEMENT WILL ALSO RESULT IN VERY HEAVY RAINFALL IN SOME AREAS. GIVEN THE LATEST MODEL DATA WITH UPPER LEVEL SUPPORT REMAINING OVER THE AREA TONIGHT...HAVE DECIDED TO BUMP EVENING POPS UP A LITTLE...INTO THE 40 TO 50 PERCENT RANGE OVER NORTHEAST FLORIDA. EAST COAST SURFACE TROUGH WILL EXTEND SOUTH THROUGH THE LOCAL FORECAST AREA ON WEDNESDAY. UPPER LEVEL PERTURBATIONS WILL ALSO BRUSH THE AREA AS THEY ROTATE AROUND THE BASE OF UPPER TROUGH WHICH WILL BE DIGGING THROUGH THE GREAT LAKES REGION. 850MB WIND MAXIMA WILL APPROACH 20 KNOTS OUT OF THE NORTHWEST BEHIND 850 TROUGH AND THIS WILL AID IN THUNDERSTORM DEVELOPMENT. DEEP CYCLONIC FLOW...AMPLE MOISTURE...AND SUFFICIENT INSTABILITY WILL ALL COMBINE TO PRODUCE SCATTERED TO NUMEROUS THUNDERSTORMS WEDNESDAY AFTERNOON. SEVERE WEATHER WILL AGAIN BE POSSIBLE BUT DEPENDENT ON AMOUNT OF INSOLATION AND REALIZED INSTABILITY. CAPES WILL PROBABLY BE HELD MUCH BELOW TODAYS VALUES GIVEN THE EXTRA CLOUD COVERAGE EXPECTED...HOWEVER...ISOLATED SEVERE THUNDERSTORMS ARE A DECENT BET GIVEN UNSEASONABLY COLD AIR ALOFT. BY THURSDAY...HIGH PRESSURE WILL BEGIN TO BUILD BACK IN. THE NAM AND GFS CONTINUE TO DISAGREE ON POPS THURSDAY AFTERNOON. THE GFS IS MUCH MORE BULLISH (40 TO 60 PERCENT) OPPOSED TO THE NAM SOLUTION OF LESS THAN 20 PERCENT POPS. THE NAM ADVECTS IN MUCH DRIER AIR BEHIND DEPARTING UPPER TROUGH AXIS IN NORTHWEST FLOW ALOFT. WILL CONTINUE TO SIDE CLOSER TO THE GFS. ENOUGH MOISTURE IS EXPECTED TO REMAIN OVER THE AREA FOR TYPICAL SUMMERTIME CONVECTION TO INITIATE ALONG MESOSCALE (SEABREEZE/OUTFLOW) BOUNDARIES. .LONG TERM...SATURDAY THROUGH TUESDAY. LATEST GFS NOW SHOWS AN INTERESTING SOLUTION FOR THE UPCOMING WEEKEND. IT SHOWS THE LARGE UPPER TROUGH OVER THE EAST COAST ATTEMPTING TO DIG BACK DOWN ALL THE WAY INTO FLORIDA ONCE AGAIN...WITH THE ATTENDANT SURFACE TROUGH IN TOW. THIS WOULD RESULT IN ELEVATED CHANCES OF PRECIP WITH POPS HIGHER THAN CLIMO VALUES. WILL CONTINUE WITH 40 PERCENT AFTERNOON POPS FOR NOW BUT IF THE GFS IS CORRECT...THESE VALUES ARE LIKELY A LITTLE ON THE LOW SIDE. NEAR NORMAL TEMPS ARE EXPECTED THROUGH THE EXTENDED PERIOD. && .AVIATION...HAVE CONTINUED TEMPO THUNDER AT ALL SITES THRU THE AFTN...WITH VCTS THRU MID TO LATE EVENING. MAY BE SOME FOG IN RECENT RAIN AREAS TONIGHT AND EVENING SHIFT CAN EVALUATE FURTHER FOG MODIFICATIONS. && .MARINE...HAVE MADE FEW CHANGES TO ONGOING FORECAST.
