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, 2.3 hours before the alert went out and 114 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.

The local office's own words before this severe thunderstorm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Melbourne, FL wrote its last area forecast discussion before this severe thunderstorm warning went out at Mar 17, 2:30 AM EST, 6 hours 47 minutes earlier.
Area forecast discussion, Mar 17, 2:30 AM EST, 6 hours 47 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE OFFICE MELBOURNE FL 230 AM EST THU MAR 17 2005 .DISCUSSION... TODAY...CURRENT HEAVY RAIN AND THUNDER MAINLY CONFINED TO THE WEST CENTRAL COAST AND PROXIMITY...BUT WITH PATCHES OF LIGHT TO MODERATE RAIN FOR THIS FORECAST AREA. EXPECT TREND TO CONTINUE THROUGHOUT MORNING WITH TRAINING-TYPE MOTION AND PARALLEL ORIENTATION. SPEED CONVERGENCE MAXIMIZED BETWEEN TAMPA AND FORT MYERS ON COAST...BUT WITH PERIODIC DEEPER INLAND PENETRATION. ADAS ANALYSIS SHOWS SURFACE BOUNDARY ACROSS NORTH FLORIDA AS REFLECTED IN THE SURFACE WIND AND TD FIELDS WITH SLOW SOUTHWARD SAG. AS SUCH...MESSY DAY IN STORE WITH PLENTY OF ATMOSPHERIC MOISTURE IN PLACE WITHIN WARM SECTOR WITH PWAT VALUES NOW 1.7 TO 2.0 INCHES. CONTINUAL CONCERN IS FOR SEVERE WEATHER POTENTIAL DUE TO PERSISTENT DYNAMICS ALOFT. PENINSULA LOCATED ON THE RIGHT REAR OF THE 300MB JET SCREAMING NORTHEAST OUT OF THE CENTRAL GULF OF MEXICO TODAY. A STREAK IS FORECAST TO ACCENTUATE OVER THE MID-ATLANTIC TO 160 KNOTS AND SHOULD CAUSE MAIN ENERGETICS TO LIFT NORTH. HOWEVER...REMNANT UNIDIRECTIONAL SOUTHWEST FLOW SHOWS IMPRESSIVE SPEEDS WELL DOWN INTO THE LOWER LEVELS WITH POTENTIAL FOR 40 KNOTS AT 850MB DURING THE MID-DAY OVER THE SOUTH. WITH ANY HEATING...THIS IS ENOUGH TO MENTION AT LEAST STRONG THUNDERSTORM POTENTIAL FOR CONVECTIVE GUSTS. MORE SO...PRECIPITATION CHANCES WILL BE CATEGORICAL TODAY WITH URBAN / SMALL STREAM FLOODING CONCERNS. TONIGHT...LOOK FOR ELONGATED SURFACE LOW TO TRANSLATE FROM THE GULF TO THE ATLANTIC BY TONIGHT AS SHORTWAVE FINALLY KICKS SYSTEM NORTHEAST. SHARPER LINE OF CLEARING TO ENSUE OVERNIGHT SHUTTING OFF MOST PRECIPITATION CHANCES AFTER 06Z. FRI...THE AXIS OF THE SHORT WAVE TROUGH WILL CROSS THE PENINSULA IN THE MORNING. SOME EARLY MORNING CLOUDS WILL GIVE WAY TO MOSTLY SUNNY SKIES AS A RIDGE BUILDS ACROSS THE EASTERN GULF. NORTHWESTERLY FLOW AROUND THE HIGH WILL USHER IN SOME COOLER AND DRIER AIR WITH HIGH TEMPERATURES RANGING FROM THE UPPER 60S NORTH TO LOWER 70S SOUTH. SAT-MON...SURFACE HIGH PRESSURE WILL GRADUALLY SLIDE EAST OF THE STATE AND INTO THE WESTERN ATLANTIC...PRODUCING VEERING FLOW AND WARMER TEMPERATURES. LOW LEVEL MOISTURE WILL ALSO INCREASE MON...GENERATING SOME ADDITIONAL CLOUDINESS. TUE-WED...LATEST RUN OF THE GFS HAS TRENDED SIGNIFICANTLY FARTHER TO THE SOUTH WITH A SHORT WAVE MOVING ACROSS THE NORTHERN GULF. THE POSITION OF THE SURFACE LOW IS NEARLY IDENTICAL TO THAT OF THE LATEST ECMWF. PRECIPITATION CAN BE EXPECTED AHEAD OF THE FRONTAL BOUNDARY TUE-WED. FAVORABLE POSITION OF THE JET ALSO POINTS TO THE POTENTIAL FOR STRONGER CONVECTION. && .MARINE...AREAS OF LIGHT TO MODERATE RAIN THIS MORNING...BUT DAYTIME CONVECTION WILL INCREASE SHOWER AND THUNDERSTORM ACTIVITY. DEEP CONVECTION SUFFICIENT TO BE CONCERNED WITH STRONG WIND GUSTS AND LOCALLY HIGHER SEAS...ESPECIALLY OVER SOUTH LEGS. AN INCREASE IN SEAS TO 6 FEET TONIGHT AS LOW TRANSLATES TO THE ATLANTIC AND ORGANIZES WHILE MAINTAINING INTO FRIDAY ON BACKSIDE NORTHERLY WINDS.
