What was reported inside it

Time	Report	Where	Remark
Jun 17, 8:55 PM EDT	HAIL 0.7	2 N Altamonte Springs, FL

Local storm reports filed while the alert was in force, from inside its polygon or its counties.

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, 0.3 hours before the alert went out and 73 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 Jun 17, 2:52 PM EDT, 5 hours 23 minutes earlier.

Area forecast discussion, Jun 17, 2:52 PM EDT, 5 hours 23 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MELBOURNE FL
252 PM EDT FRI JUN 17 2011

.DISCUSSION...
REST OF TODAY...INITIAL STORMS BEGINNING TO FIRE WITH THE HEAT OF
AFTN. ALONG THE ECSB AND LAKE BOUNDARIES. ADDITIONAL DEVELOPMENT
CAN BE ANTICIPATED OVER THE NEXT SEVERAL HOURS WITH NUMEROUS BOUNDARY
COLLISIONS AND GENERAL STORM MOTION TOWARD THE NORTH TO NORTHEAST.
ACTIVITY STRONGLY TIED TO SB HEATING WILL WIND DOWN WITH DUSK AND
END BY AROUND 10 PM. WINDS WL BECOME CALM WITH SOME AREAS OF SMOKE
AND HAZE ACROSS VOLUSIA...LAKE...ORANGE AND SEMINOLE COUNTIES.

SAT...SURFACE RIDGE AXIS REMAINS SITUATED NEAR THE CENTER PORTION
OF THE FLORIDA PENINSULA. GUIDANCE SUGGESTS MOISTURE WRAPPING
AROUND PERIPHERY OF RIDGE AND UP THE PENINSULA SATURDAY AFTERNOON
WITH A WEAK UPPER LEVEL TROUGH SLOWLY MOVING ACROSS THE STATE.
WILL GO WITH SCT STORMS DURING AFTN OVER THE INTERIOR WITH WEAK
STEERING TOWARD THE NORTH TO NORTHEAST ONCE AGAIN. HIGHS GENERALLY
IN THE LOW TO MID 90S INLAND AND NEAR 90 COAST.

SAT NIGHT-SUN...THE STORMS THAT FORM FROM LATE DAY BOUNDARY
COLLISIONS OVER THE INTERIOR ON SATURDAY MAY BE ABLE TO MOVE BACK
TOWARD THE COAST SATURDAY EVENING UNDER A WEST TO SOUTHWEST
STEERING FLOW. WILL THEREFORE KEEP A SLIGHT CHANCE OF SHOWERS AND
STORMS IN THE FORECAST FOR SATURDAY NIGHT THROUGH MIDNIGHT. WINDS
WILL BECOME LIGHT OUT OF THE SOUTH/SOUTHWEST WITH LOWS IN THE
LOW/MID 70S.

HIGH PRESSURE RIDGE AXIS WILL EXIST ACROSS SOUTH FLORIDA SUNDAY. THE
EAST COAST SEA BREEZE WILL STILL BE ABLE TO DEVELOP INTO THE
AFTERNOON BUT WILL BE DELAYED WITH LESS INLAND MOVEMENT NORTH OF THE
CAPE. AIRMASS REMAINS FAIRLY MOIST SO SHOULD STILL SEE ISOLATED TO
SCATTERED CONVECTION DEVELOP INTO THE AFTERNOON WITH ENHANCEMENT IN
ACTIVITY WITH ANY INTERACTIONS ALONG THE EAST COAST BREEZE OVER THE
AREA. RAIN CHANCES WILL BE SLIGHTLY GREATER TOWARD OKEECHOBEE AND
THE TREASURE COAST WHERE MODELS INDICATE HIGHER MOISTURE.

MON-THU...(PREVIOUS DISCUSSION) SURFACE RIDGE AXIS CONTINUES TO MOVE
SLOWLY UP AND DOWN THE PENINSULA MAKING FOR A DIFFICULT FORECAST.
DEPENDING ON WHERE THE AXIS OF THE SURFACE RIDGE IS EACH DAY IMPACTS
WHETHER SEA BREEZES START EARLY AND CLEARS THE COAST OR IS HAMPERED
FROM MAKING MUCH INLAND MOVEMENT. HIGHS EACH DAY IN THE LOWER 90S
AND OVERNIGHT LOWS IN THE LOWER 70S WHICH IS CLOSE TO THEIR CLIMO
VALUES FOR THE THIRD WEEK OF JUNE.

&&

.AVIATION...
LOCAL MVFR CONDITIONS NEAR/IN ISOLATED SHOWERS MAINLY INTERIOR
THROUGH 03Z THEN VFR AREAS BR/FU FM 08Z-12Z.

&&

.MARINE...
HIGH PRESSURE RIDGE AXIS WILL REMAIN OVER SOUTH CENTRAL/SOUTH
FLORIDA THROUGH LATE WEEKEND INTO EARLY NEXT WEEK. WINDS WILL
REMAIN GENERALLY OUT OF THE SOUTH TO SOUTHWEST...EXCEPT SOUTHEAST
ALONG THE COAST WHEN THE SEA BREEZE DEVELOPS IN THE AFT. WIND
SPEEDS WILL REMAIN AROUND 15 KTS OR LESS WITH SEAS AOB 3 FT.

&&

.FIRE WEATHER...
SCATTERED STORM DEVELOPMENT OVER INLAND LOCATIONS. LESSER
COVERAGE OF PRECIPITATION WILL OCCUR ESPECIALLY ALONG THE SPACE
AND TREASURE COAST DUE TO LIGHT STEERING WINDS AND INLAND SEA
BREEZE PENETRATION. CRITICAL FIRE WEATHER CONDITIONS ARE NOT
EXPECTED.

ISOLATED TO SCATTERED LIGHTNING STORMS WILL CONTINUE TO BE A
SOURCE OF FIRE IGNITION INTO LATE WEEKEND AND EARLY NEXT WEEK AS
THE EAST COAST SEA BREEZE DEVELOPS AND MOVES INLAND. NO LOW RH
CONCERNS ARE EXPECTED.
