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
Cape Canaveral, FL (KXMR), launched 12:00Z, 7.3 hours before the alert went out and 143 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 26, 3:00 PM EDT, 15 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MELBOURNE FL 300 PM EDT THU JUN 26 2008 .DISCUSSION... TONIGHT... CONVECTION GOT OFF TO ANOTHER EARLY START TODAY AS A VERY UNSTABLE AIRMASS REMAINS OVER THE AREA. THE 15Z RAOB SOUNDING FROM KXMR INDICATED H50 TEMPS -9C...PW 2.2...AND A SATURATED AIRMASS THRU 5KFT. SCT/NMRS SHRA/TSTRM ACTIVITY OVER THE ENTIRE CWA...THOUGH ACTIVITY WILL NOT BE AS INTENSE IN AREAS THAT HAVE ALREADY RECEIVED RAINFALL TODAY. STORM TRACK WILL BE N/NE AT 10MPH...ALLOWING VERY HEAVY RAINFALL IN SOME AREAS. SVR STORMS PSBL WITH FREQUENT TO EXCESSIVE CG LTG. DUE TO ITS EARLY START...THE CONVECTION SHOULD CONSUME MOST OF THE AVAILABLE CONVECTIVE ENERGY BY 00Z. DLM ATLC RIDGE OVER THE CENTRAL PENINSULA WILL ALLOW WINDS TO BECOME LIGHT AND VARIABLE AFTER SUNSET. DLM FLOW WILL BECOME MORE SRLY OVERNIGHT AS THE DAYTIME HEATING LOSES ITS INFLUENCE. THIS STEERING COMPONENT SHOULD KEEP ANY NOCTURNAL ATLC SHRAS OFF THE E FL COAST OVERNIGHT. WILL OPT FOR 30% OVER THE NRN PORTIONS OF THE CWA GIVEN THE LACK OF PRECIPITATION SO FAR TODAY...20% OVER THE SRN PORTIONS AS MUCH OF THE CONVECTIVE ENERGY THERE HAS BEEN CONSUMED. SFC DEWPOINTS IN THE U60S/L70S AREAWIDE WILL KEEP MIN TEMPS IN THE L/M70S. FRI-SUN... SYNOPTIC PATTERN BOTH SFC AND ALOFT FOR FRI/SAT STILL LOOKS SIMILAR TO THE LAST COUPLE DAYS. SFC RIDGE AXIS REMAIN ATOP FL WITH MID/UPR RIDGE ACROSS FL AND THE ADJCT WRN ATLC. MID/UPR TROUGH OVER THE WRN GOMEX LOOKS TO MINOR OUT AS IT EJECTS A FEW WEAK IMPULSES NEWD OVER THE TOP OF THE RIDGE AND ACROSS NE FL. MEAN LYR MOISTURE STILL LOOKS SUFFICIENT TO PRODUCE SCT CONVECTION EACH AFTN/EVENING...WITH OVERALL COVERAGE A BIT HIGHER (10%) OVER THE INTR. ACTIVITY SHOULD FOCUS OVER THE COASTAL COS FORM LATE MORNING THRU MID AFTN...AND THEN OVER THE INTR FROM MID AFTN THRU EARLY EVENING. SUN LOOKS TO BE A TRANSITIONAL DAY AS DLM TROUGH BEGINS TO DROP SE FROM THE GRTLKS INTO THE MIDWEST/OH VLY...AND MEAN RIDGING OVER/EAST OF FL STARTS TO RETREAT SEWD. GUIDANCE SUGGESTS AN INCREASE IN MEAN LYR MOISTURE WITH PWATS 1.9 - 2.1...SO HAVE NUDGED POPS UP TO 50 AREAWIDE. H50 TEMPS STILL COOL ENOUGH TO SUPPORT SCT STRONG/ISOLD SVR STORMS EACH DAY. MON-THU... DEEP LYR SW FLOW STILL EXPECT MON THRU EARLY TUE...HOWEVER MEAN LYR FLOW LOOKS A LITTLE MORE BACKED LATE TUE INTO TUE NIGHT... PERHAPS INDICATING A SLIGHTLY FASTER NWD RETURN OF DLM ATLC RIDGE. FOR NOW HAVE STILL INDICATED POPS 10% HIGHER FOR THE EAST COASTAL COS COMPARED TO THE INTR...THOUGH WE MAY NEED TO EVEN POPS OUT FOR TUE. CURRENT FCST CARRIES 40 AREAWIDE FOR BOTH WED/THU...BUT WITH THE FLOW BACKING A BIT MORE TO SSE/SE...SUSPECT WE MAY EVENTUALLY WIND UP TRENDING THE COASTAL COS BACK BY ABOUT 10% && .AVIATION...

AXIS OF THE DLM ATLC RIDGE OVER THE CENTRAL PENINSULA WILL KEEP A WEAK PGRAD OVER THE LCL ATLC WATERS OVERNIGHT. WINDS WILL RANGE FROM LIGHT AIR TO A LIGHT S/SE BREEZE AREAWIDE. TSTMS WILL MOVE OFFSHORE THRU THE REMAINDER OF THE AFTN...BUT MOST SHOULD DISSIPATE BY SUNSET. SMALL ERLY SWELL WILL KEEP OFFSHORE SEAS IN THE 2-4FT RANGE...NEARSHORE SEAS 1-3FT. BENIGN MARINE CONDS EXPECT THROUGH THE PERIOD FOR THE MOST PART. MAIN CONCERN WILL BE OFFSHORE MOVING TS FOR LATE SUN AND CONTINUING INTO MON/TUE. WNAWAVE IS INSISTENT ON BRINGING 4-5FT SEAS INTO THE OUTER WATERS...HOWEVER CURRENT SEAS OF 3FT WELL OFFSHORE ARE WELL BELOW EARLIER FCSTS...INDICATING A HIGH BIAS. CONSEQUENTLY...HAVE SHAVED A SOLID FT OFF THE WNAWAVE GUIDANCE...PEAKING SEAS OUT AT 4FT FROM FRI INTO THE WEEKEND.

LUCIE-MARTIN-COASTAL VOLUSIA- SOUTHERN LAKE-NORTHERN BREVARD- 444 AM EDT THU JUN 26 2008 THIS HAZARDOUS WEATHER OUTLOOK IS FOR EAST CENTRAL FLORIDA. .DAY ONE...TODAY AND TONIGHT. ...THUNDERSTORM IMPACT... A MOIST AND UNSTABLE AIR MASS WILL LEAD TO ANOTHER DAY WITH SCATTERED STORMS TYPICAL OF THE WET SEASON IN CENTRAL FLORIDA. STORMS SHOULD INITIATE ALONG THE EAST COAST SEA BREEZE DURING THE EARLY TO MID AFTERNOON AND GRADUALLY BUILD INLAND WHILE INCREASING IN COVERAGE AND INTENSITY. COOL TEMPERATURES ALOFT WILL LEAD TO A FEW STRONG TO SEVERE STORMS WITH THE GREATEST THREAT BEING LIGHTNING. ONE OR TWO STORMS COULD ALSO PRODUCE LARGE HAIL AND DAMAGING WINDS...ESPECIALLY ACROSS INTERIOR SECTIONS ALONG AND WEST OF INTERSTATE 4. ...FLOOD IMPACT... A SLOW NORTHWARD STORM MOTION WILL ALLOW FOR RAINFALL AMOUNTS OF 2 TO 3 INCHES IN A FEW STRONG STORMS. THIS WOULD CAUSE PONDING OF WATER ON ROADWAYS AND OTHER POORLY DRAINED AREAS. ...MARINE THUNDERSTORM GUST IMPACT... A FEW STORMS THAT DEVELOP ON THE EAST COAST SEA BREEZE MAY AFFECT THE INTRACOASTAL WATERS...MAINLY FROM CAPE CANAVERAL NORTHWARD. A FEW COULD EVEN PUSH JUST OFFSHORE IN VOLUSIA COUNTY. WIND GUSTS OF 30 TO 35 KNOTS AND FREQUENT LIGHTNING WOULD BE POSSIBLE. .DAYS TWO THROUGH SEVEN...FRIDAY THROUGH WEDNESDAY. EXPECT AFTERNOON AND EARLY EVENING LIGHTNING STORMS EACH DAY. SLOW STORM MOVEMENT RAISES THE RISK OF LOCALIZED FLOODING. COOLER TEMPERATURES ALOFT WILL PRODUCE AN INCREASED RISK OF STRONG STORMS EACH DAY. .SPOTTER INFORMATION STATEMENT... SPOTTERS SHOULD MONITOR THE WEATHER AND SELF ACTIVATE IF NECESSARY TODAY. LASCODY
