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, 8.2 hours before the alert went out and 101 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.

KONARIKWhat 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 Apr 30, 2:34 PM EDT, 1 hour 35 minutes earlier.
Area forecast discussion, Apr 30, 2:34 PM EDT, 1 hour 35 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MIAMI FL 234 PM EDT TUE APR 30 2013 .SHORT TERM (TONIGHT THROUGH THURSDAY NIGHT)... VERY COMPLEX WEATHER PATTERN IS CURRENTLY BEGINNING TO TAKE SHAPE ACROSS NORTH AMERICA WITH A CUT-OFF LOW DEVELOPING OVER SOUTHEAST TEXAS. IT THIS FEATURE THAT HAS DRAWN MOISTURE NORTHWARD ACROSS SOUTH FLORIDA AND ALSO DESTABILIZED THE ATMOSPHERE. THE 500 MB TEMPERATURES THIS MORNING WERE A COUPLE OF DEGREES WARMER THAN 24 HOURS AGO. HOWEVER, AN OFFSET TO THIS WAS THAT THE 850 MB TEMPERATURE HAVE ALSO WARMED SO THE LOWER LEVELS HAVE BECOME INCREASINGLY UNSTABLE WITH AN EARLIER ONSET OF CONVECTION THAN ON MONDAY. PWAT IS ALSO VERY HEIGHT FOR LATE APRIL AND THIS THE REASON FOR THE EXTREME RAIN. OUR RADAR HAS ESTIMATED NEAR 10 INCH TOTAL IN CORAL GABLES AREA JUST WEST OF MIRACLE MILE. STEERING FLOW IS WEST- SOUTHWEST AT 8-9 KNOTS SO DEVELOPMENT HAS BEEN OVER THE INTERIOR AND VERY SLOWLY PROPAGATING TOWARDS THE EAST COAST METRO REGION. THE GFS AND ECMWF HAVE VERY SIMILAR SOLUTIONS TO THE EVOLUTION OF THE CUT-OFF LOW THROUGH THURSDAY. THAT IS A VERY STRONG MID LEVEL TROUGH BEGINS TO DEEPEN ACROSS THE ROCKY MOUNTAIN REGION WITH THE SOUTHERN TROUGH LIFTING EVER SO SLOWLY TO THE EAST TO BE CENTERED OVER THE NORTHEAST GULF OF MEXICO BY THURSDAY. THIS WILL KEEP SOUTH FLORIDA QUITE MOIST AND UNSTABLE FOR LATE APRIL/EARLY MAY THROUGH THIS PERIOD WITH FORECAST SOUNDINGS MAINTAINING HIGH PWAT VALUES RUNNING NEARLY TWO STANDARD DEVIATIONS ABOVE NORMAL AT 1.65-1.80 INCHES. STEERING FLOW WILL ALSO REMAIN WESTERLY SO THE HIGHEST CHANCES FOR CONVECTION WILL CONTINUE OVER THE INTERIOR AND EAST COAST. ADDED TO THIS WILL BE THE DAY TO DAY FLUCTUATIONS OF THE INSTABILITY AS THE MID LEVEL LOW RETAINS ITS INFLUENCE ON THE SYNOPTIC PATTERN. AT THIS TIME, IT APPEARS THAT STRONG STORMS REMAIN POSSIBLE THROUGH THURSDAY AND CANNOT RULE OUT ISOLATED SEVERE WITH LARGE HAIL AND DAMAGING WINDS, BUT THE THREAT FOR SEVERE THUNDERSTORMS IS LOW. .LONG TERM (FRIDAY THROUGH TUESDAY)... BOTH THE GFS AND ECMWF SHOW THE CUT-OFF LOW SLOWLY GETTING ABSORBED BY THE DEEPENING TROUGH OUT WEST LATE THIS UPCOMING WEEKEND. HOWEVER, UNTIL THEN THE THREAT FOR THUNDERSTORMS WILL CONTINUE ACROSS SOUTH FLORIDA THROUGH AT LEAST SATURDAY BEFORE DRIER AIR POSSIBLY ROTATES ACROSS THE REGION FROM THE WEST. THE PRIMARY LOCATIONS WILL CONTINUE TO BE OVER THE INTERIOR AND EAST COAST AS WESTERLY STEERING IS RETAINED ALONG WITH HIGH PWAT'S FOR THIS TIME OF THE YEAR. THERE COULD ALSO BE SOME MINOR DAY TO DAY FLUCTUATIONS IN THE INSTABILITY BUT WIDESPREAD SEVERE STORMS DOES NOT APPEAR LIKELY AT THIS TIME ALTHOUGH SOME STRONG STORMS COULD OCCUR. && .MARINE... TRANQUIL MARINE CONDITIONS ARE EXPECTED TO CONTINUE BUT WITH A SMALL NORTHEAST SWELL OVER THE NORTHERN PORTIONS OF THE ATLANTIC WATERS. THERE COULD ALSO BE SOME LOCALLY ROUGH WATERS NEAR THE STRONGER THUNDERSTORMS WILL BE AFFECTING THE LOCAL WATERS THE REST OF THIS WEEK. && .FIRE WEATHER... NO PROBLEMS OR CONCERNS AS TROPICAL MOISTURE WILL REMAIN ACROSS SOUTH FLORIDA THROUGH THE END OF THIS WEEK. && .PRELIMINARY POINT TEMPS/POPS...
