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 00:00Z, 4.2 hours before the alert went out and 41 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.

.UPDATE...
SPORADIC AND SCATTERED CONVECTION CONTINUES TO DEVELOP THIS
EVENING AND MOVING ACROSS THE PENINSULA AS WAVES OF ENERGY WILL BE
MOVING ACROSS CENTRAL FLORIDA OVERNIGHT. HAVE OPTED TO JUST GO
BROAD BRUSH CHANCE OF SHOWERS WITH SLIGHT CHANCE OF THUNDER AS IN
THIS ENVIRONMENT IT WILL BE POSSIBLE FOR SOMETHING JUST ABOUT
ANYWHERE AND AT ANY TIME.

.PREV DISCUSSION... /ISSUED 756 PM EDT MON SEP 23 2013/

AVIATION...
ALTHOUGH THE BULK OF THE WIDESPREAD HEAVY RAINFALL HAS REMAINED
JUST NORTH OF THE TAF SITES ACROSS CENTRAL FLORIDA THIS
EVENING...A FEW BATCHES OF MODERATE TO HEAVY SHOWERS WITH
ISOLATED THUNDERSTORMS CONTINUE TO TRACK NORTHEAST ACROSS
PORTIONS OF THE AREA JUST INLAND OF PBI AND FLL/FXE THIS EVENING.
ELSEWHERE...CONDITIONS ARE QUIET WITH OVERCAST SKIES (VFR) AND
LIGHT SOUTHERLY LOW-LEVEL WINDS. LATER TONIGHT AND THROUGH THE
REMAINDER OF THE 24 HR TAF CYCLE...THE RAIN CHANCES WILL REMAIN IN
PLACE AS A FRONTAL BOUNDARY SLOWLY APPROACHES FROM THE NORTH AND
PLENTY OF MOISTURE CONTINUES TO OVERSPREAD THE AREA FROM THE
SOUTH. THE WINDS ARE FORECAST TO STEADILY VEER TO THE SOUTHWEST BY
THE END OF THE PERIOD AND REMAIN IN THE LIGHT TO MODERATE RANGE. 85/AG

PREV DISCUSSION... /ISSUED 253 PM EDT MON SEP 23 2013/

SHORT TERM /TONIGHT-WEDNESDAY NIGHT/...
STATIONARY FRONT OVER I-4 CORRIDOR IS SERVING AS FOCUS FOR SHOWERS
AND THUNDERSTORMS ACROSS CENTRAL FLORIDA TODAY AS DEEP TROPICAL
MOISTURE POOLS IN ITS VICINITY. SOUTH OF THE FRONT...SOUTH FLORIDA
RESIDES IN TROPICAL ATMOSPHERE ORIGINATING FROM WESTERN
CARIBBEAN...WITH PRECIPITABLE WATER VALUES IN EXCESS OF 2 INCHES.
SCATTERED SHOWERS AND ISOLATED THUNDERSTORMS HAVE BEEN MOVING
SWIFTLY NORTHEASTWARD ACROSS THE AREA...WITH GREAT COVERAGE NORTH
OF ALLIGATOR ALLEY. GUIDANCE SUGGEST THIS COVERAGE TREND WILL
CONTINUE THROUGH EARLY EVENING...THE CONVECTION WILL DIURNALLY
WANE. 0-1KM SHEAR IS FAIRLY IMPRESSIVE...AND WITH LOW LCLS AND
ENHANCED CONVERGENCE ALONG ATLANTIC BREEZE...FUNNEL
CLOUDS/WATERSPOUTS CANT BE RULED OUT THIS AFTERNOON.

OVERALL AIR-MASS IN SOUTH FLORIDA WILL CHANGE LITTLE IN THE SHORT
TERM. LOW PRESSURE IS FORMING IN EASTERN GULF ALONG THE FRONTAL
BOUNDARY AND WILL RIDE NORTHEASTWARD ALONG THE SURFACE
FEATURE...ACROSS CENTRAL FLORIDA TONIGHT AND TUESDAY. THE HEAVIEST
RAIN LOOKS TO REMAIN NORTH OF THE AREA...CLOSER TO THE SIGNIFICANT
LOW-LEVEL CONVERGENCE. STILL...WITH BROAD ASCENT AHEAD OF THE
SURFACE LOWS PARENT UPPER-LEVEL TROUGH...AMPLE INSTABILITY...AND
LOCALIZED CONVERGENCE FROM MARINE/LAND INTERACTION...SCATTERED TO
NUMEROUS THUNDERSTORMS SHOULD STILL DEVELOP OVER SOUTH
FLORIDA...ESPECIALLY NORTHERN AREAS BOTH TUESDAY AND WEDNESDAY.
TORRENTIAL RAINFALL RATES CAN BE EXPECTED WITH THIS ACTIVITY DUE
TO THE DEEP MOISTURE...SO ISOLATED FLOODING CANT BE RULED OUT EVEN
IF THE MOST ORGANIZED ACTIVITY REMAINS TO OUR NORTH. IN THE WAKE
OF THE LOW PRESSURE...THE FRONT WILL SLOWLY SAG TOWARD LAKE
OKEECHOBEE...BUT LATEST GUIDANCE DEPICTS THE BOUNDARY REMAINING
OUT OF OUR CWA THROUGH WEDNESDAY.

TEMPERATURES WILL REMAIN NEAR NORMAL...AS CLOUD-COVER AND
PRECIPITATION LIMIT DIURNAL HEATING.

LONG TERM /THURSDAY THROUGH SUNDAY/...
THE FRONT WILL CONTINUE TO MOVE SLOWLY SOUTH THROUGH SOUTH
FLORIDA ON THURSDAY...AND BY THIS WEEKEND THE FRONT SHOULD BE IN
THE FLORIDA STRAITS DUE TO STRONG HIGH PRESSURE BUILDING INTO THE
MID ATLANTIC STATES AND SOUTHEASTERN UNITED STATES. THIS WILL
ALLOW FOR THE TROPICAL MOISTURE OVER SOUTH FLORIDA TO GET PUSH
SOUTH AND ALLOW FOR DRIER AIR TO WORK INTO THE AREA FROM THE
NORTH. SO POPS WILL REMAIN IN THE CHANCE CATEGORY FOR LATE THIS
WEEK OVER SOUTH FLORIDA...BEFORE DROPPING DOWN TO THE SLIGHT
CHANCE CATEGORY FOR THIS WEEKEND. THE ONLY EXCEPTION TO THIS IS
FOR THE WEST COAST METRO AREAS WHERE A LOW END CHANCE CATEGORY
WILL BE IN PLACE EARLY THIS WEEKEND.

AVIATION...
FOR THE SHORT TERM...THE TERMINALS MOST LIKELY TO BE IMPACTED BY
THUNDERSTORMS THROUGH 19Z ARE KMIA...KFXE AND KFLL AS
SHOWERS/THUNDERSTORMS CONTINUE TO MOVE EASTWARD ACROSS THE EASTERN
HALF OF THE PENINSULA. BRIEF PERIODS OF MVFR CONDITIONS POSSIBLE AND
VERY BRIEF PERIODS OF IFR CONDITIONS POSSIBLE WITH OCCURRENCE OF
SHOWERS/THUNDERSTORMS. ALL REMAINING TERMINALS ASSIGNED VCTS AT 18Z
WITH SHOWERS/THUNDERSTORMS CONTINUING TO FORM ACROSS THE PENINSULA
AND MOVE EASTWARD WITH BRIEF PERIODS OF MVFR CONDITIONS POSSIBLE.
WILL AMEND AS NECESSARY.

MARINE...
SOUTH WINDS 10-15 KTS THROUGH TONIGHT WILL GRADUALLY VEER TO
SOUTHWEST THEN WEST TUESDAY AND WEDNESDAY. SEAS WILL BE 3 FEET OR
LESS. NUMEROUS SHOWERS AND THUNDERSTORMS WITH LOCALLY GUSTY ARE
FORECAST THROUGH MID-WEEK.

HYDROLOGY...
ORGANIZED CONVECTION HAS REMAINED NORTH OF SOUTH FLORIDA TODAY AND
APPEARS LIKELY TO REMAIN NORTH OF THE REGION TONIGHT. DESPITE
ANOMALOUSLY HIGH PWATS...FORCING AND CONVERGENCE NEEDED TO INITIATE
SIGNIFICANT CONVECTION WILL BY-AND-LARGE BE NORTH OF SOUTH FLORIDA
THROUGH MID-WEEK. THUS...WIDESPREAD HEAVY RAINFALL IS NOT
EXPECTED. STILL...AN AVERAGE OF 1-2 INCHES IS EXPECTED...HIGHEST
IN NORTHWEST ZONES. LOCALLY MUCH HIGHER TOTALS WILL BE THE
CONCERN...SO STREET/URBAN FLOODING REMAIN A THREAT THROUGH AT
LEAST WEDNESDAY.
