The archived warnings, watches and discussions in force at that minute are drawn over the scan, this one among them.
Did it verify
Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this severe thunderstorm warning while it was in force. That is not proof nothing happened: reports are thin where few people live.
Cow counts a report within 15 km of the polygon while the warning was in force: a tornado for a tornado warning; hail of 1 inch or more, a gust of 58 mph or more or wind damage for a severe thunderstorm warning; a flash flood report for a flash flood warning.
The nearest sounding before it
Miami, FL (KMFL), launched 12:00Z, 10.4 hours before the alert went out and 64 km from the middle of its area. This is the routine balloon launch nearest before it, the air the forecaster had in hand, not a measurement taken for the alert.

AKWhat forecasters said that day
The local office's own words before this severe thunderstorm warning went out, 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 this severe thunderstorm warning went out at Sep 4, 2:27 PM EDT, 3 hours 56 minutes earlier.
Area forecast discussion, Sep 4, 2:27 PM EDT, 3 hours 56 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MIAMI FL 227 PM EDT TUE SEP 4 2012 ...DEEPER MOISTURE RETURNING TO SOUTH FLORIDA LATE THIS WEEK INTO THIS WEEKEND... .SHORT TERM... AN UPPER LEVEL LOW WAS LOCATED OVER THE ATLANTIC WATERS OF SOUTH FLORIDA THIS AFTERNOON...AS A SURFACE HIGH PRESSURE SYSTEM WAS LOCATED OVER THE BAHAMA ISLANDS. THE EAST AND WEST COAST SEA BREEZES HAVE ALSO DEVELOPED AND WERE PUSHING SLOWLY INLAND EARLY THIS AFTERNOON. THIS WEATHER PATTERN WAS ALLOWING FOR SOME SHOWERS AND THUNDERSTORMS TO DEVELOP OVER THE MAINLAND AREAS OF SOUTH FLORIDA...AND SHOULD CONTINUE TO DEVELOP THROUGH THE AFTERNOON HOURS. SO WILL CONTINUE THE 30 TO 40 PERCENT POPS OVER THE CWA FOR REST OF THE AFTERNOON HOURS. THE SHOWERS AND THUNDERSTORMS SHOULD END EARLY THIS EVENING OVER MAINLAND AREAS OF SOUTH FLORIDA AS THE HEATING OF THE DAY IS LOST. HOWEVER...THERE COULD STILL BE A FEW SHOWERS AND THUNDERSTORMS OVER THE LOCAL WATERS AND THE METRO AREAS OF THE CWA TONIGHT...DUE TO THE LIGHT SOUTHERLY WIND FLOW AND THE UPPER LEVEL LOW OVER THE ATLANTIC WATERS OF SOUTH FLORIDA. SO WILL KEEP MOST OF MAINLAND SOUTH FLORIDA DRY WITH A 20 PERCENT POPS OVER THE METRO AREAS AND THE LOCAL WATERS FOR TONIGHT. THE UPPER LEVEL LOW WILL CONTINUE TO MOVE SLOWLY NORTHWARD ON WEDNESDAY THROUGH THE ATLANTIC WATERS OF SOUTH FLORIDA...BEFORE MOVING NORTHEAST INTO THE WESTERN ATLANTIC WATERS LATE THIS WEEK. THE SURFACE HIGH WILL ALSO REMAIN NEARLY STATIONARY OVER THE BAHAMA ISLANDS THROUGH END OF THE WEEK. THIS WILL KEEP THE STEERING FLOW IN A LIGHT SOUTHERLY DIRECTION...AND ALLOW FOR BOTH THE WEST AND EAST COAST SEA BREEZES TO DEVELOP AND MOVE INLAND EACH DAY. SO WILL CONTINUE THE SCATTERED POPS OVER THE CWA EACH DAY THIS WEEK WITH THE HIGHEST POPS OVER THE LAKE OKEECHOBEE AND PALM BEACH COUNTY. .LONG TERM... THE REMNANT LOW OF ISAAC OVER THE SOUTHEAST UNITED STATES WILL ALSO MOVE SOUTHWARD INTO THE NORTHEAST GULF OF MEXICO LATE THIS WEEK...BEFORE MOVING SLOWLY EAST ACROSS THE NORTHERN OR CENTRAL FLORIDA PENINSULA THIS WEEKEND. THIS WILL ALLOW FOR THE STEERING FLOW TO BECOME SOUTHWEST OVER THE CWA THIS WEEKEND ALONG WITH BRINGING IN DEEPER TROPICAL MOISTURE TO THE AREA. SO WILL CONTINUE THE SCATTERED POPS OVER THE CWA WITH THE HIGHEST POPS OVER THE LAKE OKEECHOBEE AND PALM BEACH COUNTY FOR THIS WEEKEND. THE LATEST HPC GUIDANCE IS STILL SHOWING RAINFALL TOTALS OF HALF AN INCH TO ONE INCH OVER MOST OF THE CWA FOR LATE THIS WEEK INTO THIS WEEKEND WITH EVEN ONE TO TWO INCHES OVER PALM BEACH COUNTY. HOWEVER...THE CONFIDENCE IS LOW AT THIS TIME FOR THE TOTAL RAINFALL AMOUNTS DUE TO THE STRENGTH AND LOCATION OF THE LOW. THE LATEST LONG RANGE MODELS ARE ALSO SHOWING A COLD FRONT MOVING THROUGH SOUTH FLORIDA EARLY NEXT WEEK FROM THE NORTH. THIS WILL BRING IN DRIER AND COOLER WEATHER TO THE AREA. SO AT THIS TIME...WILL KEEP A SLIGHT CHANCE OF POPS OVER THE CWA FOR EARLY NEXT WEEK. BUT THE POPS MIGHT HAVE BE LOWER OR EVEN REMOVE FROM THE ZONES FOR EARLY NEXT WEEK IF THE LONG RANGE MODEL TRENDS CONTINUE TO SHOW THE COLD FRONT MOVING THROUGH THE AREA. && .MARINE... THE WINDS WILL REMAIN SOUTHERLY AT 10 KNOTS OR LESS TONIGHT INTO THURSDAY...BEFORE SWINGING TO A SOUTHWEST DIRECTION AND INCREASING TO AT LEAST 15 KNOTS BY THIS WEEKEND. THE LATEST WNAWAVE MODEL ALONG WITH THE SWAN MODEL ARE ALSO SHOWING THAT A NORTHEAST SWELL WILL BE INCREASING OVER THE LOCAL ATLANTIC WATERS LATE THIS WEEK INTO THIS WEEKEND. BY LATE THIS WEEKEND THE MODELS ARE SHOWING A 2 TO 4 FOOT NORTHEAST SWELL IN PALM BEACH WATERS...AND A 1 TO 3 FOOT NORTHEAST SWELL IN REST OF THE ATLANTIC WATERS OF SOUTH FLORIDA. THIS WILL ALLOW FOR THE SEAS IN THE ATLANTIC WATERS TO INCREASE FROM 2 FEET OR LESS TONIGHT TO 3 TO 5 FEET THIS WEEKEND WITH ANY GETTING UP TO 6 FEET IN THE PALM BEACH WATERS. THE GULF WATERS WILL REMAIN AT 2 FEET OR LESS UNTIL THIS WEEKEND WHERE THEY WILL BE AROUND 2 TO 4 FEET. && .FIRE WEATHER... THE RELATIVE HUMIDITIES WILL REMAIN ABOVE THE 35 PERCENT CRITICAL VALUE THROUGH THIS WEEK INTO THIS WEEKEND. SO NO PROBLEMS WITH THE FIRE WEATHER PRODUCTS. && .PRELIMINARY POINT TEMPS/POPS...
