The radar

The Melbourne radar (KMLB), 55 km from the middle of the area, began a volume at 21:34 UTC, the scan nearest the moment this went out.

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 tornado 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, 9.5 hours before the alert went out and 96 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 tornado 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 tornado warning went out at Aug 11, 4:07 PM EDT, 1 hour 25 minutes earlier.

Area forecast discussion, Aug 11, 4:07 PM EDT, 1 hour 25 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MELBOURNE FL
407 PM EDT WED AUG 11 2010

.DISCUSSION...
...REST OF TODAY THRU TONIGHT...TD 5 OVER THE EASTERN GULF LOCATED
ABOUT 170 MILES SOUTH OF PENSACOLA FLORIDA AS OF 400 PM EDT. IS
EXPECTED TO CONTINUE TO WEAKEN AS IT MOVES INTO THE NORTH CENTRAL
GULF OF MEXICO. THE AREA REMAINS UNDER SOUTH-SOUTHWESTERLY FLOW
BETWEEN GULF FEATURE AND THE ATLANTIC RIDGE SLOWLY SINKING
SOUTHWARDS ACROSS GA/SC. A MOIST ENVIRONMENT REMAINS ON THE
PERIPHERY OF THE SYSTEM WITH SOUNDINGS ALONG THE EAST COAST OF THE
STATE DROPPING A BIT FROM THIS MORNING TO AROUND 2.0"-2.1" AND
KTBW CLOSER TO TD 5 COMING IN WITH ~2.5".

SCATTERED SHOWERS AND ISOLATED THUNDERSTORMS CAN BE EXPECTED
THROUGH THIS EVENING WITH STRONGER CELLS CONTAINING GUSTY WINDS
AND HEAVY DOWNPOURS. VOLUSIA COUNTY IN PARTICULAR HAS SEEN
TRAINING THROUGHOUT THE DAY SO A SLIGHT FLOOD THREAT REMAINS
THROUGH THIS EVENING. IN ADDITION...ROTATION HAS BEEN DETECTED BY
RADAR IN SOME OF THE CELLS WHERE BOUNDARIES HAVE COLLIDED.

A BRIEF...WEAK TORNADO OR WATERSPOUT CANNOT BE RULED
OUT...ESPECIALLY ALONG THE COAST AND INTRACOASTAL COMMUNITIES.
OVERNIGHT HOURS WILL SEE CLEARING OF THESE SHOWERS FOR THE MOST
PART. THE RUC IS DEPICTING A VORTICITY MAX AT 300MB AND 250MB
MOVING INTO THE SOUTHERN PORTIONS OF THE CWA. THIS COULD ALLOW FOR
SOME SLIGHT CHANCES OF SHOWERS TO CONTINUE IN THIS AREA WITH ANY
MOISTURE REMAINING BEHIND THE OUTGOING TD.

THURSDAY...A DRIER AIRMASS ASSOCIATED WITH THE RIDGE WILL BE PUSHING
INTO EAST CENTRAL FLORIDA...REDUCING PRECIPITATION CHANCES ACROSS
THE CWA. INITIAL RUNS SHOWED MAX TEMPS IN THE UPPER 90S THROUGHOUT
THE INTERIOR PORTIONS. BUMPED THESE VALUES DOWN A NOTCH TO THE MID
90S TO REFLECT THE WARMER THAN AVERAGE TEMPS...BUT NOT QUITE DRY
ENOUGH TO SHOW CLOSE TO RECORD TEMPS.

FRI-NEXT WED...(PREVIOUS) HIGH PRESSURE RIDGE AXIS IS FORECAST TO
REMAIN TO OUR SOUTH THROUGH THE WEEKEND AS A WEAK FRONTAL BOUNDARY
PUSHES TO AROUND 30N. THIS WOULD CONTINUE A WEST COMPONENT TO THE
GRADIENT WIND FLOW...AND FAVOR THE EAST SIDE OF THE PENINSULA FOR
SCATTERED POPS. MODELS SUGGEST REMNANT MOISTURE FROM THE BOUNDARY
MAY AFFECT THE AREA LATE IN THE WEEKEND OR EARLY NEXT WEEK.
HOWEVER...HAVE CAPPED VALUES AT 40 PERCENT FOR NOW DUE TO THE
WARMER THAN NORMAL TEMPS ALOFT...THOUGH A FEW DAYS WITH HIGHER
COVERAGE SHOULD OCCUR ESPECIALLY IN THE NORTH. PICKING OUT THE
DAYS IN THE EXTENDED RANGE WHERE VERY HIGH MOISTURE HELPS TO
OVERCOME THE WEAK LAPSE RATES HAS BEEN MOSTLY FUTILE DURING OUR
WET SEASON SO FAR.

&&

.AVIATION...
SCT SHRA/ISOLD TSRA WILL CONTINUE ACROSS THE AREA THROUGH 00Z
WITH TEMPO IFR/MVFR CONDITIONS WITH ANY ACTIVITY. S-SE GUSTS
20-25KTS OUTSIDE OF SHRA/TSRA...WITH GUSTS UP TO 30KTS IN STORMS.
CONDITIONS BECOMING VFR AFTER 00Z WITH MID LEVEL CONVECTIVE
DEBRIS.

&&

.MARINE...
TONIGHT-THURSDAY...PRESSURE GRADIENT BTW TD #5 OVER THE EASTERN GULF AND
HIGH PRESSURE RIDGE EAST OF THE AREA WILL MAINTAIN A SE FLOW OVER
THE WATERS...THOUGH NOTABLY WEAKER THAN YESTERDAY AT ONLY TO 10-15
KTS. WINDS TO VEER TO THE S TONIGHT AS TD 5 PULLS FURTHER AWAY INTO
THE NORTH CENTRAL GULF. SEAS CONTINUE TO SUBSIDE AS PGRAD SLACKENS
AT 3-4FT OFFSHORE...BECOMING 2-3 FT TONIGHT. MAINLY SOUTHERLY FLOW
CONTINUES THURSDAY WITH LIGHTER WINDS IN THE MORNING INCREASING TO
5-10 KNOTS BY THE AFTERNOON. ISOLATED SHOWERS AND THUNDERSTORMS
CLOSE TO THE DAILY DIURNAL FLORIDA CYCLE.

THU-WEEKEND...HIGH PRESSURE RIDGE AXIS WILL REMAIN SOUTH OF THE WATERS.
THIS WILL CAUSE A WEST/SOUTHWEST FLOW 10 KNOTS OR LESS...EXCEPT
ACROSS THE NORTH THU-FRI WHERE REMNANT TD #5 LOW AND/OR WEAK FRONTAL
TROUGH KEEP THE GRADIENT FLOW A LITTLE HIGHER. THE MAIN CONCERN
FOR BOATERS WILL BE AFTERNOON STORMS THAT MOVE ACROSS THE COAST.

THIS HAZARDOUS WEATHER OUTLOOK IS FOR EAST CENTRAL FLORIDA.

.DAY ONE...THIS AFTERNOON AND TONIGHT.

...THUNDERSTORM IMPACT...
TROPICAL DEPRESSION NUMBER 5 CURRENTLY OVER THE EASTERN GULF OF
MEXICO WILL KEEP A MOIST SOUTH TO SOUTHEAST FLOW OVER THE AREA
THIS AFTERNOON. SCATTERED SHOWERS AND ISOLATED THUNDERSTORMS WILL
BE POSSIBLE OVER EAST CENTRAL FLORIDA THROUGH EARLY THIS EVENING.
SHOWERS AND STORMS WILL MOVE NORTH TO NORTHWEST AT AROUND 25 MPH.
THE MAIN THREAT FROM STORMS WILL BE GUSTY WINDS OF UP TO 40
MPH...BRIEF HEAVY DOWNPOURS...AND DEADLY CLOUD TO GROUND LIGHTNING
STRIKES. THERE IS ALSO A VERY LOW THREAT OF A BRIEF TORNADO.

...RIP CURRENT IMPACT...
WEATHER AND OCEAN CONDITIONS WILL KEEP AN ELEVATED RISK FOR RIP
CURRENTS ALONG THE AREA BEACHES. ONCE ARRIVING AT THE BEACH...
CHECK WITH A LIFEGUARD FOR THE CURRENT RIP CONDITIONS AND NEVER
SWIM ALONE.

...MARINE THUNDERSTORM GUST IMPACT...
SCATTERED SHOWERS AND ISOLATED STORMS WILL DEVELOP ACROSS THE AREA
THIS AFTERNOON AND MOVE TOWARD THE NORTH TO NORTHWEST AROUND 25
MPH. ANY STRONGER ACTIVITY WILL BE ABLE TO PRODUCE WIND GUSTS IN
EXCESS OF 35 KNOTS OVER INLAND LAKES.

...WATERSPOUT IMPACT...
ENVIRONMENTAL CONDITIONS WILL BE CONDUCIVE FOR ISOLATED
WATERSPOUTS OVER THE NEARSHORE ATLANTIC WATERS. SPOUTS MAY BRIEFLY
DEVELOP AT THE COAST AND OR INTRACOASTAL WATERWAY...POSSIBLY MOVING
ASHORE WHILE DISSIPATING.

.DAYS TWO THROUGH SEVEN...THURSDAY THROUGH TUESDAY.
SURFACE ATLANTIC HIGH PRESSURE RIDGE WILL BUILD BACK OVER CENTRAL
AND SOUTHERN FLORIDA FROM LATE THIS WEEK INTO THE WEEKEND. THIS
WILL KEEP MORE NORMAL COVERAGE OF SHOWERS AND STORMS ACROSS THE
AREA EACH AFTERNOON. A DEVELOPING WESTERLY STEERING FLOW WILL
INCREASE THE THREAT FOR OFFSHORE MOVING THUNDERSTORMS INTO THE
WEEKEND.

.SPOTTER INFORMATION STATEMENT...

SPOTTER ACTIVATION WILL NOT BE NEEDED TODAY.
