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
Tampa Bay, FL (KTBW), launched 12:00Z, 11.3 hours before the alert went out and 71 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.

Area forecast discussion, Jun 8, 3:47 PM EDT, 3 hours 29 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE TAMPA BAY RUSKIN FL 347 PM EDT SUN JUN 8 2014 .NEAR TERM (TONIGHT-MONDAY)... MOSTLY CLEAR CONDITIONS AT THE COAST THIS AFTERNOON AS THE SEA BREEZE HAS PUSHED INLAND. THUNDERSTORMS ARE BEGINNING TO FIRE EAST OF I-75 AND THIS IS WHERE THE MAJORITY OF THE ACTIVITY IS EXPECTED FOR THE REMAINDER OF THE AFTERNOON AND EVENING. A DRY FORECAST IS EXPECTED TONIGHT ONCE WE LOSE DAYTIME HEATING AND ANY LEFTOVER STORMS DISSIPATE. FOR MONDAY...THE MID/UPPER RIDGE OVER THE GULF WILL BUILD EASTWARD IN RESPONSE TO A TROUGH MOVING THROUGH THE CENTRAL PART OF THE COUNTRY. AT THE SURFACE...THE RIDGE AXIS WILL HOLD ACROSS THE PENINSULA AND ALLOW BOTH THE WEST AND EAST COAST SEA BREEZE TO PROPAGATE INLAND. THIS WILL AGAIN BE THE FOCUS FOR SCATTERED SHOWER AND THUNDERSTORM DEVELOPMENT AND WILL CONTINUE TO SHOW THE HIGHEST POPS ACROSS THE INTERIOR WITH THE SEA BREEZE COLLISION. .MID TERM (MONDAY NIGHT-TUESDAY)... MID LEVEL RIDGING OVER THE GULF OF MEXICO AT THE START OF THE WORK WEEK WILL SHIFT EAST TOWARDS FLORIDA AS A STRONG TROUGH BUILDS INTO THE SOUTH-CENTRAL PLAINS. SURFACE RIDGING WILL HOLD IN PLACE ACROSS THE CENTRAL FLORIDA PENINSULA...KEEPING WINDS LIGHT ENOUGH FOR BOTH EAST AND WEST COAST SEA BREEZES TO ADVANCE INLAND. WITH PRECIPITABLE WATER VALUES FORECAST TO BE BETWEEN 1.7 AND 2.0 INCHES...SCATTERED THUNDERSTORMS SHOULD DEVELOP EACH AFTERNOON...WITH THE HIGHEST CHANCES OVER THE INTERIOR. ADDITIONALLY...THE SOUTHWEST FLORIDA COAST COULD SEE HIGH STORM CHANCES LATE TUESDAY AFTERNOON AS THE EAST COAST SEA BREEZE FORCES ITSELF ALL THE WAY ACROSS THE STATE. HIGH TEMPERATURES WILL CONTINUE TO RUN IN THE UPPER 80S AND LOW 90S...WITH LOWS MONDAY NIGHT IN THE LOW TO MID 70S. .LONG TERM (TUESDAY NIGHT-SATURDAY)... BY MIDWEEK...A DEEP UPPER LEVEL TROUGH WILL BE SPRAWLED ACROSS MUCH OF THE EASTERN CONUS AND WILL SLOWLY TREK EAST TOWARDS THE ATLANTIC. ALTHOUGH THIS SYSTEM WILL PULL A COLD FRONT INTO THE SOUTHEASTERN STATES...THE STRENGTH OF THE SURFACE RIDGE ACROSS FLORIDA WILL ALLOW IT TO HOLD IN PLACE THROUGH THE REST OF THE WEEK...KEEPING A FAIRLY REPETITIVE PATTERN IN PLACE. LIGHT WINDS IN THE MORNINGS WILL GIVE WAY TO AFTERNOON SEA BREEZES...WITH SCATTERED THUNDERSTORMS DEVELOPING OVER THE INTERIOR DURING THE AFTERNOON AND CONTINUING THROUGH THE EVENING. HIGH TEMPERATURES WILL CONTINUE TO RUN IN THE UPPER 80S AND LOW 90S...WITH LOWS MONDAY NIGHT IN THE LOW TO MID 70S. && .AVIATION... MOSTLY VFR EXPECTED. KLAL STILL HAS THE BEST CHANCE AT EXPERIENCING REDUCTIONS DUE TO THUNDERSTORMS AND WILL LEAVE VCTS IN FOR NOW AND AMEND AS NEEDED. && .MARINE... SURFACE HIGH PRESSURE OVER THE WESTERN ATLANTIC WITH A RIDGE AXIS EXTENDING ACROSS THE CENTRAL FLORIDA PENINSULA AND EASTERN GULF OF MEXICO WILL HOLD OVER THE REGION THROUGH MID-WEEK THEN GRADUALLY SINK SOUTH LATE IN THE WEEK WITH INCREASING ONSHORE FLOW. WINDS WILL REMAIN LESS THAN 15 KNOTS WITH SEAS LESS THAN 3 FEET THROUGH THE PERIOD. MAIN HAZARD EACH DAY WILL BE ISOLATED THUNDERSTORMS WHICH WILL PRODUCE LOCALLY GUSTY WINDS AND ROUGH SEAS. && .FIRE WEATHER... NO FIRE WEATHER ISSUES EXPECTED. JUST SOME PATCHY AND SHALLOW GROUND FOG POSSIBLE. && .PRELIMINARY POINT TEMPS/POPS...
