The episode as NWS JAX wrote it up.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE JACKSONVILLE FL
214 PM EDT SAT AUG 17 2013
.SHORT TERM...
THE SHORT WAVE TROUGH WILL BEGIN TO LIFT NORTHWEST WITH THE OLD
BOUNDARY AND FOCUSING MECHANISM SHIFTING NORTH AND WEST WITH IT.
WITH THAT WE SHOULD SEE A BREAK FROM THE SURGES OF PRECIPITATION
THAT HAVE BEEN COMING OUT OF THE GULF OVER THE PAST FEW DAYS AND
SHIFT TO MORE NORMAL THUNDERSTORM ACTIVITY. WITH A SYNOPTIC
SOUTHWESTERLY FLOW PATTERN JUST ABOUT EVERYONE SHOULD SEE SOME
CONVECTION OVER THE NEXT 24 HOURS BUT SHOULD NOT BE A COMPLETE
WASHOUT.
SUNDAY AND SUNDAY NIGHT.... CLOSED LOW OVER THE MID MISSISSIPPI
VALLEY WILL WEAKEN AND MOVE OFF TO THE NORTHEAST ON SUNDAY CAUSING
THE STATIONARY FRONTAL BOUNDARY TO RETREAT NORTHWARD AS HIGH
PRESSURE BUILDS IN FROM THE WESTERN ATLANTIC. HIGHEST CHANCES TO
SEE CONVECTION WILL BE IN AREAS CLOSEST TO THE BOUNDARY ACROSS SE
GA AND INLAND AREAS ACROSS NE FL WHERE SEA BREEZE TRIGGERED
SHOWERS AND THUNDERSTORMS WILL FORM DURING THE AFTERNOON. EXPECT
TEMPS TO ONLY GET INTO THE UPPER 80S ACROSS SE GA WITH MOSTLY
CLOUDY CONDITIONS FOR A MAJORITY OF THE DAY. ELSEWHERE...TEMPS
WILL BE IN THE UPPER 80S ALONG THE COAST AND LOW 90S ACROSS INLAND
NE FL. LOWS WILL REMAIN NEAR SEASONAL NORMS IN THE LOW TO MID 70S.
.LONG TERM...
MONDAY THROUGH TUESDAY NIGHT... HIGH PRESSURE...LOCATED OVER THE
WESTERN ATLANTIC...WILL CONTINUE TO BUILD OVER THE AREA SLOWLY
PUSHING OUT THE STATIONARY FRONTAL BOUNDARY AND ALLOWING EASTERLY
FLOW TO SETTLE IN. WITH SOME LINGERING MOISTURE LEFT OVER FROM THE
BOUNDARY EXPECT PRECIP CHANCES TO RISE TO NEAR 50 PERCENT ACROSS
INLAND LOCATIONS EACH AFTERNOON. THUNDERSTORMS WILL SLOWLY
DECREASE IN INTENSITY AND COVERAGE AFTER SUNSET EACH DAY WITH
OVERNIGHT CONVECTION POSSIBLE IN THE COASTAL WATERS. TEMPS MON AND
TUES WILL BE IN THE UPPER 80S ALONG THE COAST TO LOW 90S INLAND
WITH LOW/MID 70S EACH NIGHT.
WEDNESDAY THRU FRIDAY NIGHT...HIGH PRESSURE WILL BEGIN TO BREAK
DOWN LATE ON WEDNESDAY AND INTO THURSDAY AS MID LEVEL TROUGH MOVES
OVER THE EASTERN US. THERE IS NOT MUCH CONSISTENCY BETWEEN LONG
TERM MODELS AS TO THE DEVELOPMENT OF THIS TROUGH. THE 00Z EUROPEAN
IS MORE AGGRESSIVE WITH THIS FEATURE CLOSING IT OFF OVER THE
CAROLINAS BY FRIDAY WITH 12Z GFS LEAVING IT AS AN OPEN WAVE. WITH
SLIGHTLY DRIER AIR IN PLACE EXPECT WIDELY SCATTERED SHOWERS AND
THUNDERSTORMS TO DEVELOP WEDS/THURS AFTERNOON WITH BEST CHANCES
BEING ACROSS INLAND LOCATIONS EXCEPT ON FRIDAY WHEN COVERAGE IS
EXPECTED TO BE MORE WIDESPREAD ACROSS THE AREA WITH ENTRANCE OF
THE PREVIOUSLY MENTIONED UPPER TROUGH. A FEW COASTAL SHOWERS AND
THUNDERSTORMS WILL BE POSSIBLE EACH MORNING WITH PREVAILING EAST
TO SOUTHEASTERLY FLOW THROUGHOUT THE DAY. TEMPERATURES WILL REMAIN
NEAR SEASONAL NORMS IN THE UPPER 80S ALONG THE COAST AND LOW 90S
INLAND WITH LOWS IN THE LOW TO MID 70S.
&&
.AVIATION...
IN THE SHORT TERM THE BIGGEST PROBLEM WILL BE CONVECTION IN THE
MCKINNON AIRPORT AREA THIS AFTERNOON. AFTER THE IMPULSE PASSES TO
THE NORTHEAST WE SHOULD BE GOOD WITH JUST TS IN THE VICINITY FOR ALL
OF THE FIELDS. NOT LOOKING FOR MUCH IN THE WAY OF FOG PROBLEMS
OVERNIGHT.
&&
.MARINE...
SOUTHERLY FLOW WILL SHIFT TO EAST/SOUTHEASTERLY BY TOMORROW MORNING
AND CONTINUE THROUGH THURSDAY. CONDITIONS SHOULD NOT REACH CAUTION
CRITERIA THIS WEEK WITH SEAS BETWEEN 2 TO 4 FEET AND WINDS REMAINING
BETWEEN 10 TO 15 KTS. BEST CHANCES FOR CONVECTION ACROSS THE
COASTAL WATERS WILL BE OVERNIGHT AND INTO THE EARLY MORNING HOURS.
RIP CURRENTS: LOW RISK OF RIP CURRENTS EXPECTED THROUGH SUNDAY MORNING
WITH A MODERATE RISK SUNDAY AFTERNOON AND EVENING AS EASTERLY FLOW
STRENGTHENS. AFTER THAT...LOW RISK IS EXPECTED THROUGH MID WEEK.
