The episode as NWS MFL wrote it up.
A cluster of thunderstorms over the Everglades merged with the sea breeze in the Naples area and led to numerous thunderstorms with heavy rain in the evening hours. In addition to the lightning impacts, a total of 6-10 inches of rain fell in the North Naples area between 8 pm and midnight. This caused significant street flooding in the Quail Run community where about a dozen cars were stranded and had to be towed away, as well as forcing the closure of several area streets.
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 Miami, FL wrote its last area forecast discussion before the first event at Sep 6, 6:36 PM EST, 54 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MIAMI FL 736 PM EDT FRI SEP 6 2013 .AVIATION... VFR PREVAILING AT ALL TERMINALS. VCTS ONLY FOR KAPF THIS EVENING DUE TO THE ACTIVITY ALREADY NEARBY. EXPECT THIS TO DISSIPATE BY 04Z. VCSH WILL POSSIBLY DEVELOP NEAR ALL EASTERN TERMINALS BY 07/16Z AND WEST COAST SEA BREEZE DEVELOPING BY 07/18Z. VCTS WILL BE POSSIBLE NEAR KAPF BY THAT TIME ALSO. && .PREV DISCUSSION... /ISSUED 230 PM EDT FRI SEP 6 2013/ ..TYPICAL SUMMER TIME WEATHER THIS WEEKEND BEFORE DRIER CONDITIONS EARLY NEXT WEEK... SHORT TERM... THE EAST AND WEST COAST SEA BREEZES HAVE DEVELOPED EARLY THIS AFTERNOON WITH THE EAST COAST SEA BREEZE PUSHING ACROSS THE INTERIOR AREAS. THE EAST COAST SEA BREEZE WILL CONTINUE TO PUSH WEST ACROSS SOUTH FLORIDA THROUGH THE AFTERNOON HOURS...AS THE WEST COAST SEA BREEZE REMAINS OVER THE WEST COAST METRO AREAS. AT THE SAME TIME...A TROUGH OF LOW PRESSURE OVER NORTH FLORIDA WILL CONTINUE TO MOVE SOUTH INTO CENTRAL FLORIDA. THIS WEATHER PATTERN WILL ALLOW FOR ISOLATED TO SCATTERED SHOWERS AND THUNDERSTORMS TO DEVELOP OVER THE INTERIOR AND WEST COAST METRO AREAS THIS AFTERNOON INTO EARLY THIS EVENING...WITH ISOLATED SHOWERS ONLY FOR THE EAST COAST METRO AREAS. SO WILL KEEP THE 30 TO 50 PERCENT POPS IN PLACE FOR THE INTERIOR AND WEST COAST METRO AREAS THROUGH EARLY THIS EVENING...WITH ONLY A 20 PERCENT POPS OVER THE EAST COAST METRO AREAS OF SOUTH FLORIDA. THE TROUGH OF LOW PRESSURE WILL REMAIN NEARLY STATIONARY TONIGHT OVER CENTRAL FLORIDA...BEFORE MOVING SLOWLY SOUTH INTO THE LAKE OKEECHOBEE AREA ON SATURDAY AND THROUGH SOUTH FLORIDA ON SUNDAY. THIS WILL KEEP THE STEERING FLOW OVER SOUTH FLORIDA IN A LIGHT NORTHEAST DIRECTION ALONG WITH THE SEA BREEZE DEVELOPMENT EACH DAY ALONG BOTH COAST. SO THE SCATTERED POPS WILL REMAIN OVER THE INTERIOR AND WEST COAST METRO AREAS WITH ISOLATED POPS OVER THE EAST COAST METRO AREAS EACH DAY THIS WEEKEND. THE THREAT OF THUNDER WILL ALSO BE FOCUS MAINLY OVER THE INTERIOR AND WEST COAST METRO AREAS EACH DAY THIS WEEKEND..BUT THE EAST COAST METRO AREAS COULD SEE A THUNDERSTORM OR TWO. THE 500 MB TEMP WILL ALSO REMAIN VERY COLD FOR THIS TIME OF YEAR IN THE -8C TO -9C OVER SOUTH FLORIDA. THIS WILL ALLOW FOR SOME OF THE STORMS EACH DAY THIS WEEKEND TO BECOME STRONG OVER SOUTH FLORIDA ESPECIALLY WHERE THE SEA BREEZES COLLIDE EACH DAY. THE PRIMARY IMPACTS FROM THE STRONG STORMS WILL MORE LIKELY BE LIGHTNING STRIKES, GUSTY WINDS, AND HAIL. SO WILL MENTION THIS IN THE AFTERNOON HWO PACKAGE. LONG TERM... THE TROUGH OF LOW PRESSURE WILL MOVE INTO THE FLORIDA KEYS EARLY NEXT WEEK BEFORE MOVING BACK UP INTO SOUTH FLORIDA FOR THE MIDDLE OF NEXT WEEK...AS AN UPPER LEVEL LOW DEVELOPS OVER THE WESTERN ATLANTIC WATERS. THIS WILL ALLOW FOR SOME DRIER AIR TO WORK INTO SOUTH FLORIDA FROM THE NORTH EARLY NEXT WEEK...BEFORE MOISTURE RETURNS TO THE AREA FOR MIDDLE OF NEXT WEEK. THEREFORE...THE POPS FOR EARLY NEXT WEEK HAVE BEEN LOWER TO SLIGHT CHANCE OVER MOST OF SOUTH FLORIDA EXCEPT LOW END CHANCE OVER THE WESTERN AREAS. FOR MIDDLE OF NEXT WEEK...THE POPS WILL REMAIN IN THE CHANCE CAT OVER SOUTH FLORIDA. AVIATION... A WEAK TROUGH IS TRYING TO MAKES ITS WAY INTO SOUTH FLORIDA THIS AFTERNOON. THIS SHOULD ACT TO ENHANCE CONVECTION IN THE WESTERN HALF OF THE AREA. THE SEA BREEZE WILL KEEP THE EAST COAST CLEAR OF MOST CONVECTION, ALTHOUGH AN ISOLATED SHOWERS MAY STILL TRY TO FORM. GIVEN THIS, HAVE KEPT ANY SHRA/TSRA OUT OF THE EASTERN SITES THIS AFTERNOON. FOR KAPF, HAVE DELAYED VCTS FOR A FEW HOURS AS THE MODELS INDICATE IT WILL BE MORE TOWARDS THE MID AFTERNOON BEFORE CONVECTION AFFECTS NAPLES. HOWEVER, THIS COULD BE OFF A LITTLE, SO VCTS MAY NEED TO ADDED, OR EVEN DELAYED SOME, BASED ON DEVELOPMENT. WINDS WILL BE GENERALLY EASTERLY THIS AFTERNOON, WITH THE EXCEPTION OF KAPF, WHERE THE GULF BREEZE IS EXPECTED TO JUST MAKE IT PAST THE AIRPORT. TONIGHT, WINDS WILL LIGHTEN AND GO VARIABLE IN MANY LOCATIONS. THEY WILL ONCE AGAIN BECOME EASTERLY TOMORROW BETWEEN 5 AND 10 KTS. MARINE... THE WINDS WILL REMAIN FROM THE EAST NORTHEAST AT 10 KNOTS OR LESS THIS WEEKEND INTO EARLY NEXT WEEK OVER ALL OF SOUTH FLORIDA WATERS. THIS WILL KEEP THE SEAS IN BOTH THE ATLANTIC AND GULF WATERS AT 2 FEET OR LESS. SO BOATING CONDITIONS WILL BE GOOD OVER ALL OF SOUTH FLORIDA WATERS OUTSIDE OF ANY SHOWERS AND THUNDERSTORMS. && .PRELIMINARY POINT TEMPS/POPS...

FREQUENT CLOUD-TO- GROUND LIGHTNING WILL BE THE GREATEST THREAT. THE RISK FOR RIP CURRENTS ALONG ATLANTIC BEACHES WILL PERSIST AND POSSIBLY INCREASE EARLY NEXT WEEK AS STRONGER ONSHORE WINDS DEVELOP. THE DAYTIME HEAT INDEX COULD REACH ABOVE 100 DEGREES. PORTIONS OF INLAND COLLIER COUNTY MAY EXPERIENCE A HEAT INDEX NEAR 105 DEGREES. .SPOTTER INFORMATION STATEMENT... SPOTTER ACTIVATION WIDESPREAD SPOTTER ACTIVATION IS NOT ANTICIPATED, HOWEVER INDIVIDUAL SPOTTERS ARE ENCOURAGED TO REPORT HIGH WIND, HAIL AND FLOODING TO THE NATIONAL WEATHER SERVICE FORECAST OFFICE IN MIAMI.
