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

Key West, FL (KEYW), launched 12:00Z, 7.5 hours before the alert went out and 158 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.

SOUTH FLORIDA FORECAST DISCUSSION...CORRECTED
NATIONAL WEATHER SERVICE MIAMI FL
ISSUED BY NATIONAL WEATHER SERVICE KEY WEST FL
245 PM EDT MON JUN 14 2004

.DISCUSSION...
A WEAK WESTERN ATLANTIC SURFACE RIDGE WILL LIE NEAR SOUTH CENTRAL
FLORIDA THROUGH THE BALANCE OF THIS WEEK...WHILE A WEAK PERTURBATION
MIGRATES WESTWARD ACROSS SOUTH FLORIDA AND THE KEYS WEDNESDAY AND
WEDNESDAY NIGHT. MEANWHILE...A MID AND UPPER LEVEL ANTICYCLONE
COVERING THE EASTERN UNITED STATES AND FLORIDA PENINSULA...WILL BE
UNDERCUT BY A WESTWARD MOVING TROUGH FRIDAY AND SATURDAY.
SUBSEQUENTLY...THE OVERALL STEERING FLOW WILL SLOWLY BACK TO EAST BY
TUESDAY AFTERNOON...THEN NORTHEAST WEDNESDAY AND THURSDAY...BEFORE
VEERING TO SOUTHEAST FRIDAY. REGARDLESS...DESPITE SLIGHTLY DRIER AIR
IN THE MID AND UPPER LEVELS...THE BEST CHANCE FOR SHOWERS AND STORMS
WILL BE OVER THE WESTERN HALF OF THE PENINSULA...WITH ONLY ISOLATED
SHOWERS AND STORMS ELSEWHERE. BEGINNING SUNDAY...MRF IS NOW
INDICATING AN EASTERLY STEERING FLOW WHICH WOULD ALLOW THE EASTERN
HALF OF THE SOUTHERN PENINSULA TO REQUIRE HIGHER POPS.
HOWEVER...SINCE THIS IS HIGHLY QUESTIONABLE AND THE FIRST RUN WITH
THIS SCENARIO...NO CHANGES WILL BE MADE AT THIS TIME.

.MARINE...WITH THE WESTERN ATLANTIC RIDGE LYING NEAR SOUTH CENTRAL
FLORIDA OVER THE NEXT SEVERAL DAYS...A LIGHT EAST TO SOUTHEAST FLOW
WILL PREVAIL.
