Verified. The Iowa Environmental Mesonet's Cow matched 3 storm reports to this severe thunderstorm warning; the first came 32 minutes after it went out.

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.

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 Mar 26, 3:02 PM EDT, 2 hours 40 minutes earlier.

Area forecast discussion, Mar 26, 3:02 PM EDT, 2 hours 40 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MELBOURNE FL
302 PM EDT SAT MAR 26 2016

.DISCUSSION...

FROM MID TO LATE AFTN...THUNDERSTORMS WILL DEVELOP IN THE RELATIVELY
UNENCUMBERED AIRMASS WITH FURTHER MOVEMENT TOWARD THE EAST COAST.
ALL FACTORS POINT TO THE LIKELIHOOD OF SOME STRONG TO POSSIBLY
SEVERE STORMS ONCE BOUNDARIES INTERACT IN THE ECFL AREA. MAIN
CONCERNS WILL BE FREQUENT LIGHTNING AND LARGE HAIL ALONG WITH THE
POSSIBILITY OF SOME DAMAGING WIND GUSTS. HRRR GUID INDICATES A LATE
AFTERNOON MAXIMA OF STORM COVERAGE WITH A PERSISTENCE OF SCT STORMS
WELL INTO THE NIGHT TIME PERIOD WHILE MOVING OFFSHORE THE EAST
COAST.

TONIGHT AND SUNDAY...LINGERING SHOWERS AND EMBEDDED TS SHOULD COME
TO AN END OVER LAND AREAS BY MIDNIGHT WITH TRANSITION TO THE MARINE
AREA FOR THE LATE NIGHT AND A GRADUAL DECREASE IN DEBRIS CLOUDINESS.
WL SEE SOME PATCHY FOG AND LOW CLOUD DEVELOPMENT TOWARD DAYBREAK
SUNDAY GIVEN THE LIGHT TO CALM WINDS AND RAIN WETTED GROUND...MAINLY
IN THE TRADITIONALLY FOG PRONE LOCATIONS. LITTLE CHANGE IN WEATHER
FEATURES WILL BRING ANOTHER ROUND OF AFTERNOON STORMS TO THE AREA.
FAVORABLE MOISTURE AND DLM STEERING WINDS WL FAVOR THE EAST COAST
AND SOME STRONG STORMS WILL DEVELOP BY LATE AFTERNOON.

SUN NIGHT-MON NIGHT...THE QUASI-STATIONARY SURFACE BOUNDARY WILL
STILL REMAIN NORTH OF ECFL EARLY IN THE PERIOD AND MOVE OFF OF THE
EASTERN SEABOARD ON MON WITH SOUTHERN PORTION LAGGING INTO NORTH
FL...FINALLY PUSHING INTO THE AREA MON OVERNIGHT. THE SURFACE RIDGE
AXIS WILL CONTINUE TO RETREAT DEEPER INTO THE WESTERN ATLC. NEAR
ZONAL FLOW ALOFT WITH OCCASIONAL MID-LEVEL IMPULSES TRAVERSING THE
REGION. ABUNDANT DEEP LAYER MOISTURE IN UPWARDS OF 1.60-1.70 INCHES
WILL POOL ALONG AND AHEAD OF THE SURFACE BOUNDARY. HIGHEST POPS SUN
EVENING FAVORING THE NORTH WITH SEA BREEZE COLLISIONS ACROSS THE
INTERIOR AND STORMS PUSHING BACK TOWARD THE COAST...THEN FOCUS
FURTHER SOUTH ON MON AFTERNOON/EVENING. LOWS REMAINING MILD IN
THE 60S TO AROUND 70 DEGREES. HIGHS ON MON IN THE L-M80S.

...PREVIOUS EXTENDED FORECAST DISCUSSION...

TUE-SAT...SLIGHT DRYING IS INDICATED TUE AS THE FRONTAL TROUGH DROPS
SOUTH...BUT THE LATEST GFS AND ECMWF SHOW A DISTURBANCE APPROACHING
WHICH WILL NECESSITATE CHANCE POPS. TEMPS ALOFT ARE FORECAST TO BE
QUITE COLD SO CANNOT RULE OUT THUNDER AGAIN TUE AFTERNOON. SURFACE
HIGH MOVING OFF THE COAST TO OUR NORTH WILL PROVIDE AN ONSHORE FLOW
WED. AN OVERALL MORE STABLE ATMOSPHERE IS INDICATED AS WEAK RIDGING
MOVES OVERHEAD. POPS AROUND 20 PERCENT WITH THUNDER CHANCES SHIFTED
WELL INLAND LOOK IN ORDER. LOW LEVEL WINDS ARE FORECAST TO TURN
SOUTHEAST THU AND SOUTH ON FRI. THIS WILL INCREASE MOISTURE AND
SHOULD BRING A SMALL CHANCE FOR AFTERNOON STORMS. HIGHS WILL
CONTINUE A LITTLE ABOVE NORMAL IN THE LOWER-MID 80S. OVERNIGHT LOWS
WILL BE ABOUT 5-10 DEGREES ABOVE NORMAL IN THE MID 60S.

&&

.AVIATION...SCT CIGS AND VSBY INTERRUPTED BY PCPN ALONG WITH SCT
STORMS WITH SOME REDUCTIONS TO MVFR AND BRIEF IFR TONIGHT THROUGH
27/03Z. CONDS BECMG VFR AFT 27/04Z. THERE WILL BE SOME PATCHY GROUND
FOG POSSIBLE IN RAIN AFFECTED AREAS EARLY SAT MNLY FM 27/09Z-27/12Z.

&&

.MARINE...TONIGHT/SUNDAY...WITH THE ATLC RIDGE AXIS LIFTING N OF THE
FORECAST AREA LIGHT ONSHORE WINDS WILL PREVAIL. SEAS AROUND 2 FT
NEAR SHORE AND 3 TO 4 FT WELL OFFSHORE CAN BE EXPECTED. MARINERS
WILL SEE THE PRIMARY THREAT FROM THE COASTAL STORMS VICE PREVAILING
WIND AND SEA STATE WHICH ASIDE FROM STORMS.

SUN NIGHT...NEAR STATIONARY FRONTAL BOUNDARY REMAINING NORTH OF THE
AREA WITH PLENTY OF MOISTURE AROUND AND DISTURBANCES ALOFT. THE HIGH
PRESSURE RIDGING WILL CONTINUE TO WEAKEN AND RETREAT TOWARDS THE
SOUTH AND EAST. OFFSHORE MOVING CONVECTION IN THE EVENING DUE TO SEA
BREEZE COLLISIONS OVER THE MAINLAND AND STORM STEERING FLOW TAKING
REMNANTS OFF OF THE COAST...INTRACOASTAL WATERWAYS AND NEAR SHORE
ATLC WATERS. STORM MOTION TOWARD THE EAST OR ENE AT 20 TO 25 MPH.
WIND GUSTS IN EXCESS OF 35 KTS...TORRENTIAL DOWNPOURS...FREQUENT
LIGHTNING AND SMALL HAIL CONTINUE TO BE THE MAIN THREATS. LOCALLY
HIGHER SEAS INVOF STRONGER STORMS.

SERLY WINDS ALONG THE COAST FROM THE LATE DAY SEA BREEZE WILL VEER
BACK TO SSW IN THE EVENING/OVERNIGHT WITH SPEEDS 10-13 KTS OVER THE
OPEN ATLC. SEAS GENERALLY 2-3 FT NEAR SHORE AND 3-4 FT OFFSHORE.

...PREVIOUS MARINE EXTENDED DISCUSSION...

MON-THU...SURFACE RIDGE AXIS WILL GET NUDGED SOUTH MON AS TAIL END
OF FRONTAL BOUNDARY DROPS IN TO NORTH FLORIDA.  WINDS WILL VEER TO
THE SOUTHWEST WITH SPEEDS 10-15 KNOTS.  GREATEST CHANCE FOR OFFSHORE
MOVING STORMS IN THE AFTERNOON/EVENING LOOKS TO BE SOUTH OF CAPE
CANAVERAL. THE PRESSURE GRADIENT IS FORECAST TO EASE LATE MON INTO
TUE AS THE FRONTAL TROUGH WEAKENS ACROSS THE WATERS. IT LOOKS DRIER
OVERALL BUT A SLIGHT CHANCE FOR OFFSHORE MOVING STORMS EXISTS TUE
AFTERNOON. HIGH PRESSURE TO THE NORTH IS SHOWN BRIDGING THE OLD
FRONTAL BOUNDARY ON WED WITH WINDS FRESHENING OUT OF THE EAST. SMALL
SHOWER CHANCES EXPECTED BUT MAIN CHANCE FOR STORMS SHOULD BE WELL
INLAND.

THIS HAZARDOUS WEATHER OUTLOOK IS FOR EAST CENTRAL FLORIDA.

.DAY ONE...LATE THIS AFTERNOON AND TONIGHT.

.THUNDERSTORM IMPACT...
SUFFICIENT MOISTURE AND INSTABILITY WILL EXIST FOR SCATTERED
THUNDERSTORMS TO DEVELOP ACROSS THE AREA LATE THIS AFTERNOON AND
EARLY EVENING. STORM DEVELOPMENT AND INTENSITY WILL BE ASSISTED LATE
THIS AFTERNOON OVER THE INTERIOR DUE TO MESOSCALE BOUNDARY
COLLISIONS FROM SEA AND LAKE BREEZES...AS WELL AS PREVIOUS STORM
OUTFLOW BOUNDARIES. STEERING FLOW ALOFT WILL MOVE STORMS TOWARD THE
NORTH-NORTHEAST UP TO 20 TO 25 MPH...EVENTUALLY PUSHING OFFSHORE THE
VOLUSIA AND BREVARD COASTS LATE IN THE AFTERNOON AND EVENING.

MAIN THREATS WILL BE FREQUENT CLOUD TO GROUND LIGHTNING...STRONG
WIND GUSTS UP TO 45 TO 55 MPH AND SMALL HAIL. HOWEVER AN ISOLATED
THREAT FOR LOCALLY DAMAGING WIND GUSTS AND LARGE HAIL WILL ALSO
EXIST. A BRIEF TORNADO MAY OCCUR...ESPECIALLY AT THE COASTAL ZONE
WHERE ONSHORE WIND CAN ENHANCE DIRECTIONAL SHEAR IN THE EAST MOVING
LOCAL STORM ENVIRONMENT.

.FLOOD IMPACT...
ANY STRONGER STORMS WILL HAVE THE POTENTIAL TO PRODUCE LOCALLY
HEAVY RAINFALL UP TO 2 TO 3 INCHES LATE THIS AFTERNOON AND EVENING.
THIS WILL LEAD TO MINOR FLOODING OF ROADWAYS AND POOR DRAINAGE
AREAS...ESPECIALLY ACROSS AREAS THAT HAVE ALREADY RECEIVED
ABUNDANT RAINFALL OVER THE PAST COUPLE OF DAYS.

.RIP CURRENT IMPACT...
WEATHER AND OCEAN CONDITIONS WILL LEAD TO A MODERATE THREAT FOR
DANGEROUS RIP CURRENTS AT EAST CENTRAL FLORIDA BEACHES TODAY. THE
THREAT WILL BE HIGHEST THROUGH SUNSET DUE TO TIDAL EFFECTS.

.MARINE THUNDERSTORM GUST IMPACT...
LATE AFTERNOON AND EVENING THUNDERSTORMS WILL MOVE TOWARD THE
NORTHEAST AT 20 TO 25 MPH. A FEW STRONGER STORMS WILL HAVE THE
POTENTIAL TO PRODUCE WIND GUSTS OF 35 KNOTS OR HIGHER OVER INLAND
LAKES AND AS THEY PUSH OFF THE EAST COAST LATE THIS AFTERNOON AND
EVENING.

.DAYS TWO THROUGH SEVEN...SUNDAY THROUGH FRIDAY.
ISOLATED TO SCATTERED AFTERNOON LIGHTNING STORMS ARE FORECAST INTO
EARLY NEXT WEEK. THE PRIMARY THREAT WILL BE CLOUD TO GROUND
LIGHTNING BUT A FEW STORMS COULD BECOME STRONG CONTAINING SMALL HAIL
AND GUSTY WINDS.

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