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, 7.3 hours before the alert went out and 109 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.

What 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 May 19, 2:37 PM EDT, 39 minutes earlier.

Area forecast discussion, May 19, 2:37 PM EDT, 39 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MIAMI FL
237 PM EDT SAT MAY 19 2012

.SHORT TERM...TONIGHT THROUGH TUESDAY...A BROAD MID TO UPPER TROUGH
CONTINUES TO EXTEND FROM THE MID ATLANTIC REGION SOUTHWEST TO
NORTH-CENTRAL PORTIONS OF THE GULF OF MEX. AT THE SAME TIME...A
WEAK LOW LEVEL TROUGH CONTINUES TO EXTEND FROM A DISTURBANCE JUST
OFF THE CAROLINAS SOUTHWEST TO SOUTH CENTRAL FLORIDA. NEITHER ONE
OF THESE FEATURES IS EXPECTED TO MOVE MUCH THROUGH AT LEAST
TUESDAY. THIS WILL CONTINUE TO RESULT IN UNSETTLED WEATHER
CONDITIONS. GOOD UPPER LEVEL DYNAMICS COUPLED WITH DIURNAL HEATING
AND LOCAL SEA/LAKE BREEZES WILL LEAD TO DAILY AFTERNOON TSTMS
THROUGH THIS PERIOD. ALTHOUGH CONVECTIVE ACTIVITY CAN BE EXPECTED
OVER ANY PORTION OF SOUTH FLORIDA...A WESTERLY STEERING FLOW WILL
TEND TO FAVOR STORMS MOVEMENT MORE TOWARD EASTERN INTERIOR AND
EAST COAST.

.LONG TERM...WEDNESDAY THROUGH SATURDAY...THE UPPER TROUGH SHOULD
BEGIN TO LIFT NORTHEAST AND BE REPLACED BY AN UPPER RIDGE.
MODERATE SUBSIDENCE ASSOCIATED WITH THIS RIDGE SHOULD LEAD TO
SLIGHTLY DRIER CONDITIONS THROUGH THIS PERIOD. PREVIOUS GFS RUNS
WERE INDICATING A DISTURBANCE IN THE LOW LEVEL EASTERLIES OVER
THE WESTERN CARIBBEAN WITH THE NORTHERN EDGE MOVING ACROSS S.
FLORIDA THURSDAY THROUGH SATURDAY. HOWEVER...LATEST RUNS ARE NOT
AS AGGRESSIVE AND NOW KEEP MOST OF THE PRECIP SOUTH OF THE LOCAL
AREA. IN VIEW OF THIS...WL GO CLOSE TO CLIMO AND KEEP LOW SCT POPS
THROUGH THIS PERIOD.

&&

.MARINE...SFC WINDS SHOULD REMAIN MOSTLY EAST AND REMAIN LIGHT
THROUGH THE MIDDLE OF NEXT WEEK. A SMALL NE SWELL SHOULD BEGIN TO
AFFECT THE ATLANTIC WATERS FROM SUNDAY ON.

THIS HAZARDOUS WEATHER OUTLOOK IS FOR SOUTH FLORIDA.

.DAY ONE...TODAY AND TONIGHT

THUNDERSTORMS: SCATTERED THUNDERSTORMS ARE FORECAST TO DEVELOP
ACROSS SOUTH FLORIDA THIS AFTERNOON INTO EARLY THIS

FAVORABLE LOW LEVEL WIND PROFILE WILL RESULT IN A SLIGHT RISK OF
WATERSPOUTS.

LIGHTNING AND LOCALIZED HEAVY RAINS BEING THE PRIMARY RISKS AT
THIS TIME.
