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
Cape Canaveral, FL (KXMR), launched 12:00Z, 7.6 hours before the alert went out and 61 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, May 11, 2:55 PM EDT, 39 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MELBOURNE FL 255 PM EDT WED MAY 11 2005 .DISCUSSION... CURRENTLY...THUNDERSTORMS INCREASING IN COVERAGE OVER THE EAST SIDE OF THE FL PENINSULA THANKS TO DESTABILIZING CONDITIONS FROM UPPER LOW OFF TO THE EAST. CONVECTION IS BEING ENHANCED BY EAST COAST SEA BREEZE. OVER THE SOUTH A DRIER AIRMASS HAS LIMITED ACTIVITY...BUT WITH SEA BREEZE DEVELOPMENT AND MODEST MOISTENING EXPECT ISOLD ACTIVITY OVER THE SOUTH INTERIOR DURING THE REMAINDER OF THE AFTERNOON. MAIN CONCERN CONTINUES TO BE POTENTIAL FOR HAIL AND LOCAL CONVECTIVE WIND GUSTS AS ADDRESSED IN THE HWO. TONIGHT...UPPER LOW CENTERED ALONG LAT 30 N OVER THE MARINE AREA EAST OF THE STATE WL CONTINUE TO SPIN OVERNIGHT WHILE WEAKENING. GFS/NAM SHUNTS ASCD UPPER VORT CENTER IN A MEAN SW DIRECTION ACROSS PENINSULA OVERNIGHT. THIS REMNANT VORT CENTER COMBINED WITH COOL TEMPS ALOFT AND LINGERING CONVECTIVE/BREEZE BOUNDARIES WILL ASSIST IN SOME LINGERING SHOWERS/ ISOLD THUNDER THIS EVENING OVER THE INTERIOR AND NORTHERN SECTIONS. COVERAGE AMTS SHOULD NOT RANGE ANY HIGHER THAN ABOUT 20 PERCENT AFTER LOSS OF SURFACE HEATING. FORECAST WL REVERT TO PARTLY CLOUDY AFTER MIDNIGHT WITH LIGHT TO CALM WINDS. LOW LYING AND RAIN AFFECTED AREAS MAY SHOW LOCALIZED LIGHT FOG BY SUNRISE...BUT NOT ENOUGH TO MENTION IN FORECAST. THU AND BEYOND...HIGH PRESSURE BUILDS IN FROM THE NORTH THU AND A BRINGS A RETURN OF BRISK EASTERLY FLOW FOR FRI. AS HIGH CENTER SHIFTS EAST INTO THE ATLC THIS WEEKEND...A TRAILING RIDGE AXIS WILL SLIP SOUTH INTO NORTH FLORIDA SUN. BREEZY EASTERLY WINDS EXPECTED AGAIN SAT ESP SOUTH OF THE CAPE BUT NOT AS STRONG SUNDAY AS PRESSURE GRADIENT WEAKENS INVOF RIDGE AXIS. A WEAK UPPER TROUGH IS FORECAST TO MOVE EAST ACROSS FL SUN AND MAY PROVIDE ENOUGH DESTABILIZATION TO PRODUCE ISOLATED SHOWERS AND STORMS. BUT MOISTURE WILL BE THE PRIMARY LIMITING FACTOR FOR CONVECTION SO WILL KEEP SUNDAY DRY FOR NOW. HIGH PRESSURE REESTABLISHES ITSELF NORTH OF THE AREA EARLY NEXT WEEK AND WILL PROVIDE AN ONSHORE FLOW WITH VERY LOW RAIN CHANCES AND TEMPS RIGHT AROUND NORMAL. && .AVIATION...LOCAL IFR AND SHRA/THUNDERSTORM ACTIVITY MAINLY OVER INLAND LOCATIONS THROUGH ABOUT 02Z.
