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, 11.2 hours before the alert went out and 72 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, Jul 6, 2:17 PM EDT, 4 hours 54 minutes before
EAST CENTRAL FLORIDA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MELBOURNE FL 217 PM EDT TUE JUL 6 2004 .DISCUSSION... CONVECTION HAS BEEN LATER TO GET UNDERWAY THIS AFTERNOON THAN PAST FEW DAYS. EAST COAST SEA BREEZE FORMATION IS SO FAR CONFINED TO FAR SOUTHERN CWA. 15Z CAPE SOUNDING INDICATES LOW LEVEL WESTERLY FLOW A BIT HIGHER WHICH IS HELPING DELAY THE FORMATION...BUT WILL NOT BE ENOUGH TO INHIBIT IT COMPLETELY. THROUGH TONIGHT...COVERAGE OF STORMS SHOULD INCREASE LATE THIS AFTERNOON AS MORE BOUNDARY INTERACTIONS OCCUR. FLOW IN THE H85-H5 LAYER STILL QUITE WEAK AND MODELS INDICATE MEAN STEERING THROUGH THIS LAYER WILL BE TOWARD THE S-SW AND HAVE PENCILED IN SLIGHTLY HIGHER POPS OVER THE INTERIOR THAN E COAST. FREQUENT LIGHTNING AND HEAVY DOWNPOURS PRIMARY THREATS WITH THESE STORMS BUT SUFFICIENTLY INSTABILITY EXISTS AGAIN FOR A FEW STRONG/MARGINAL SEVERE STORMS ALONG BOUNDARY COLLISIONS LATE AFTERNOON THROUGH EARLY EVENING. WED-FRI...THE RIDGE AXIS CURRENTLY SUPPRESSED SOUTHWARD BY TROUGH MOVING OFF THE EASTERN SEA BOARD WILL REMAIN SOUTH OF THE FORECAST AREA INTO THE END OF THE WORK WEEK. RESULTING WESTERLY FLOW WILL BE LIGHT SO THE SEA BREEZE WILL BE ABLE TO FORM ALBEIT SOMEWHAT DELAYED FROM USUAL MIDDAY FORMATION. THIS SHOULD FAVOR THE EASTERN PORTION OF THE PENINSULA FOR PCPN DURING BOTH INITIAL SEA BREEZE BOUNDARY FORMATION AND AND LATE AFTERNOON ACTIVITY THAT MOVES EAST FROM INLAND SECTIONS. WILL STAY WITHIN THE SCATTERED RANGE FOR SHOWERS AND STORMS. FRIDAY RIDGE AXIS BEGINS TO LIFT BACK NORTHWARD AND GREATEST RAIN CHANCES CAN BE EXPECTED OVER THE INTERIOR WHERE BOUNDARY INTERACTIONS WILL BE MOST NUMEROUS DURING THE AFTERNOON. SHOULD BE A CONTINUATION OF SLOW MOVING STORMS WITH LOCALLY HEAVY RAIN. EXTENDED...RIDGE AXIS LIFTS INTO N FL SAT WITH A WEAK TROPICAL WAVE MOVING BY SOUTH OF THE RIDGE. ONSHORE FLOW REGIME ACROSS THE AREA WITH HIGH MOISTURE WILL ALLOW FOR SCT PCPN DURING THE WEEKEND. THIS SHOULD GIVE SOUTHERN COASTAL AREAS SOME MORNING RAIN CHANCES BEFORE AFTERNOON CONVECTIVE INITIATION OCCURS INLAND ALONG THE SEA BREEZE. THE LOW LEVEL RIDGE AXIS LOOKS TO REMAIN OVER CENTRAL FLORIDA EARLY NEXT WEEK. GFS SHOWING ANOTHER MORE POTENT WAVE APPROACHING FROM THE TROPICAL ATLANTIC TOWARD THE MIDDLE OF NEXT WEEK. SEE NO NEED TO VARY POPS FROM SCT COVERAGE EACH DAY. && .MARINE...FORECAST DEPENDANT ON POSITION OF RIDGE AXIS. WITH AXIS REMAINING SOUTH OF THE AREA NEXT COUPLE OF DAYS WILL SPLIT FORECAST COASTAL -VS- OFFSHORE TO ACCOUNT FOR BOTH SEA BREEZE AND FETCH PROTECTION. MAIN BOATING CONCERN WILL BE ISOLATED STORMS/OUTFLOW BOUNDARY GUSTS NEAR SHORE THE NEXT FEW DAYS. && .PRELIMINARY POINT TEMPS/POPS...
