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 00:00Z, 3.7 hours before the alert went out and 36 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.

What forecasters said that day

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 May 23, 9:00 PM EDT, 2 hours 39 minutes earlier.

Area forecast discussion, May 23, 9:00 PM EDT, 2 hours 39 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MELBOURNE FL
900 PM EDT FRI MAY 23 2008

.DISCUSSION...

...SCATTERED/NUMEROUS SHOWERS/STORMS SATURDAY THEN DRYING...

CURRENTLY-TONIGHT...IMPULSE PULLING EAST OF THE AREA ALONG WITH MOST
CONVECTION.  OUTFLOW BOUNDARIES OVER LAND HAVE BEEN INITIATING SOME
SMALLER AREAS OF CONVECTION WHERE POCKETS OF INSTABILITY LINGER.
THIS ACTIVITY WILL DIMINISH BEFORE MIDNIGHT.

WATER VAPOR LOOP SHOWS DRYING ALOFT WORKING IN BEHIND IMPULSE SO
MID/HIGH CLOUDS WILL CLEAR OUT.  NEXT UPSTREAM SHORTWAVE TROUGH
SHOULD START TO SPREAD SOME MID/HIGH CLOUDS BACK ACROSS THE AREA
LATE.  WITH SOME RAIN WETTING AND A PERIOD OF MOSTLY CLEAR SKIES
WILL HAVE TO WATCH FOR SOME LOW STRATUS OR FOG.  THE GFS SHOWS 925
MB WESTERLY WINDS INCREASING TO 15 KNOTS IN THE NORTH.  SOUTHERN
AREAS SHOULD HAVE BOUNDARY LAYER FLOW LESS THAN 10 KNOTS...AND THE
GREATEST RAIN WETTING OCCURRED THERE.  PLAN TO PULL SMALL POPS FROM
THE OVERNIGHT PART OF THE FORECAST AND PUT IN PATCHY FOG.

SATURDAY (PREVIOUS DISCUSSION)...SHORTWAVE WILL PUSH OFF SE U.S.
COAST WITH SURFACE LOW FORMATION OFF THE GA/SC COAST. WESTERLY WIND
COMPONENT WILL PERSIST BUT WILL BEGIN TO SEE A SHIFT TO NORTHERLY
COMPONENT LATE IN THE DAY WITH BACK DOOR FRONT REACHING THE NE
FRINGES. MOISTURE WILL REMAIN DEEP SO SHOWER/STORM CHANCES WILL
REMAIN ON THE HIGH SIDE.

&&

.AVIATION...ISOLATED SHOWERS/LIGHTNING STORMS WILL DIMINISH BEFORE
04Z THEN EXPECT A PERIOD OF MOSTLY CLEAR SKIES.  THIS SHOULD ALLOW
FOR SOME PATCHY FOG...EVEN THOUGH GFS AND LAMP MOS ARE NOT SHOWING
ANY FOG OR LOW CEILINGS.  RIGHT NOW WE ARE ONLY CALLING FOR 3-5SM
BR...BUT WILL HAVE TO WATCH OUT FOR LOWER VISIBILITIES...ESPECIALLY
ACROSS SOUTH PARTS WHERE BOUNDARY LAYER WINDS WILL BE LIGHTER AND
RAIN WETTING WAS THE GREATEST.

EXPECT DAYTIME HEATING AND FRONTAL MOISTURE WILL IGNITE SCATTERED TO
NUMEROUS SHOWERS/STORMS ON SAT AND EXPECT SOME WILL BECOME STRONG.

&&

.MARINE...SOME QUITE STRONG STORMS PUSHED OFFSHORE THIS EVENING. ONE
PRODUCED FREQUENT LIGHTNING AND MOVED OVER 41009...LUCKILY IT IS
STILL TRANSMITTING DATA  THERE ARE NO WIND/SEA CONCERNS THROUGH SAT
WITH WEST WINDS AT 10 KNOTS OR LESS.  THE WAVE WATCH IS SHOWING 1
FOOT SEAS AT 41009.  THE MAIN CONCERN WILL BE STORMS MOVING OFFSHORE
AHEAD OF FRONTAL BOUNDARY THAT WILL DROP THROUGH SAT NIGHT.  STORMS
WILL BE MOVING SOUTHEAST AND SOME WILL PRODUCE STRONG WIND GUSTS AND
FREQUENT LIGHTNING.

&&

.FIRE WEATHER (PREVIOUS DISCUSSION)...HIGHER MOISTURE AND PRECIP
CHANCES BEFORE FRONTAL PASSAGE WILL KEEP RH VALUES FROM REACHING
CRITICAL THRESHOLDS THROUGH SAT. EVEN AFTER FRONT PUSHES THROUGH AND
DRIER AIR MOVES IN...WINDS WILL QUICKLY BECOME NELY SUN/MON SO
CRITICAL THRESHOLDS NOT ANTICIPATED BUT WILL WATCH TRENDS THROUGH
SUBSEQUENT RUNS.

THIS HAZARDOUS WEATHER OUTLOOK IS FOR EAST CENTRAL FLORIDA.

.DAY ONE...TODAY AND TONIGHT.

...THUNDERSTORM IMPACT...
AN UPPER LEVEL DISTURBANCE MOVING EAST ALONG THE GULF COAST WILL
BRING INCREASED INSTABILITY TO CENTRAL FLORIDA TODAY. COMBINED
WITH SOME MORE HEATING THAN YESTERDAY AND THE PRESENCE OF THE EAST
COAST SEA BREEZE BOUNDARY...WE EXPECT A HIGH COVERAGE OF RAIN AND
LIGHTNING STORMS TO DEVELOP NORTH OF ORLANDO LATER THIS AFTERNOON.
MORE SCATTERED LIGHTNING STORMS ARE EXPECTED SOUTH OF ORLANDO.
CONDITIONS WILL BE FAVORABLE FOR HEAVY RAIN AND DOWNBURST WINDS OF
40 TO 50 MPH. AN ISOLATED SEVERE STORM WITH DAMAGING WINDS AND
LARGE HAIL WILL BE POSSIBLE. STORM MOVEMENT WILL BE TOWARD THE
EAST AT 15 TO 20 MPH.

...MARINE THUNDERSTORM GUST IMPACT...
SCATTERED TO NUMEROUS LIGHTNING STORMS ARE EXPECTED TO MOVE
OFFSHORE MAINLY FROM MID AFTERNOON TO EARLY EVENING. STORMS WILL
BE CAPABLE OF PRODUCING WIND GUSTS IN EXCESS OF 35 KNOTS ON THE
INTRACOASTAL AND NEAR SHORE ATLANTIC WATERS...MAINLY NORTH OF
COCOA BEACH.

...FIRE WEATHER IMPACT...
THERE EXISTS A FIRE DANGER FROM THE COMBINATION OF HIGH DROUGHT
INDICES AND THE THREAT FOR CLOUD TO GROUND LIGHTNING STRIKES AND
STRONG WIND GUSTS FROM THUNDERSTORMS TODAY.

.DAYS TWO THROUGH SEVEN...SATURDAY THROUGH THURSDAY.
SCATTERED STORMS WILL BRING THE THREAT FOR CLOUD TO GROUND
LIGHTNING AND GUSTY WINDS AGAIN SATURDAY AFTERNOON. THE RIP
CURRENT RISK WILL INCREASE SUNDAY THROUGH TUESDAY AS LONG PERIOD
SWELLS ARRIVE IN THE AREA. WINDS AND SEAS WILL INCREASE TO
HAZARDOUS LEVELS SUNDAY THROUGH MONDAY.

.SPOTTER INFORMATION STATEMENT...
SPOTTERS ARE REQUESTED TO MONITOR THE WEATHER AND SELF ACTIVATE
IF NEEDED.
