What was reported inside it

Time	Report	Where	Remark

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 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.

Area forecast discussion, Mar 11, 3:30 PM EST, 1 hour 28 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MELBOURNE FL
330 PM EST THU MAR 11 2010

.DISCUSSION...

...SEVERE STORMS POSSIBLE THIS EVENING AND AGAIN ON FRIDAY...

...HEAVY RAIN BECOMING WIDESPREAD FRIDAY...

TONIGHT/FRI...
ACTIVE WX PATTERN FOR FL THRU THE PD.  A LARGE STORM SYSTEM
BLANKETING THE NATIONS MIDSECTION WILL COMBINE WITH A MID LVL
ANTICYCLONE OVER THE NW CARIB/WRN ATLC TO GENERATE A STRONG SWRLY
FLOW ACROSS THE GOMEX/DEEP SOUTH.  THESE WINDS WILL PULL DEEP
MOISTURE INTO THE REGION THAT WILL POOL WITHIN A BROAD FRONTAL TROF
OVER THE GOMEX.  MEANWHILE...A +160KT H25 JET OVER THE RIO GRANDE
VALLEY/NW GOMEX WILL GENERATE STRONG UPR LVL DIVERGENCE AS A SERIES
OF MID LVL DISTURBANCES TRACK ACROSS FL PENINSULA.

PRECIP WILL TAPER OFF THRU EARLY EVENING OVER THE NRN CWA AS THE
LINE OF STORMS DROPS S OF THE I-4 CORRIDOR.  HOWEVER...UPSTREAM
MOISTURE AND REGIONAL DYNAMIC LIFT IS PLENTIFUL.  ANTICIPATE
ADDITIONAL ROUNDS OF PRECIP TO DEVELOP OVER THE PENINSULA OVERNIGHT.

DEFINITIVE POPS AREAWIDE THRU THE PD...80%-100%.  LAPSE RATES THRU
BOTH THE H85-H70 AND H85-H50 LYRS ARE SOMEWHAT SHALLOW OVER THE
IMMEDIATE VICINITY...GENERALLY AOB 6.5C/KM.  HOWEVER...STEEPER LAPSE
RATES OVER THE CENTRAL GOMEX (AOA 7.5C/KM) EMBEDDED WITHIN THE DEEP
SWRLY FLOW COULD ADVECT INTO THE PENINSULA OVERNIGHT. FURTHERMORE...
STRONG SPEED AND DIRECTIONAL SHEAR OVER THE REGION WILL GIVE ANY
CELLS THAT DO FORM THE POTENTIAL TO ROTATE.

THIS WEEKEND...VORTEX IN THE NATIONS MIDSECTION WILL PUSH ONLY
SLOWLY EASTWARD AND BE ALONG THE MID ATLANTIC COAST ON SUNDAY. BOTH
THE GFS/ECMWF SHOW COLD FRONT TO OUR EAST EARLY SAT SO HAVE REMOVED
SMALL RAIN CHANCES IN THE SOUTH.  A WESTERLY LOW LEVEL FLOW WILL
LIMIT THE COOLING BEHIND THIS FRONT AND TEMPS SHOULD BE JUST A
LITTLE BELOW NORMAL BY SUNDAY. BROAD LOW LEVEL CYCLONIC FLOW SHOULD
ALSO BRING SOME CLOUDINESS ACROSS THE PENINSULA SO WE ARE NOT
LOOKING FOR A PERFECTLY SUNNY WEEKEND. ALSO EXPECT BREEZY CONDITIONS
ESPECIALLY ON SAT.

MON-THU...THE EAST COAST TROUGH IS FORECAST TO LIFT EARLY IN THE
WEEK WITH HIGH PRESSURE RIDGE NOSING IN BEHIND IT. THIS SHOULD
KEEP IT DRY MON-TUE. TEMPS ARE PROGGED TO CONTINUE A LITTLE BELOW
NORMAL BUT OVERALL QUITE PLEASANT AFTER THE COLD WINTER WE HAVE HAD.

THE NEXT SHORTWAVE TROUGH COMING ALONG IN THE SOUTHERN STREAM IS
FORECAST ON ABOUT WED. THE MODELS HAVE BEEN SHOWING THAT THIS WILL
NOT BE AS STRONG OF A SYSTEM AS IT ENTERS A CONFLUENT UPPER LEVEL
FLOW PATTERN OVER THE EASTERN PART OF THE COUNTRY. STILL THESE
SPRING-LIKE SYSTEMS CAN BRING A QUICK SHOT OF HIGH MOISTURE...SO
WILL HAVE SMALL POPS IN THE FORECAST FROM TUE NIGHT-THU.

.MARINE...
MODERATE TO FRESH S/SW BREEZE WILL CONTINUE TO GENERATE HAZARDOUS
BOATING CONDITIONS OVERNIGHT. PGRAD WILL SLACKEN AS A FRONTAL TROF
OVER THE WRN GOMEX PUSHES TOWARD TH FL PENINSULA OVERNIGHT...
ALLOWING WINDS TO DIMINISH AND VEER TO THE NW BY DAYBREAK SAT.
WHILE SEAS WILL DECREASE ALONG WITH THE DIMINISHING WINDS...THE
PERSISTENT OFFSHORE COMPONENT WILL GENERATE CHOPPY SHORT PD SEAS
THRU FRI.  SCA IN PLACE FOR ALL COASTAL ZONES THRU 03Z.

THIS WEEKEND...FLOW BEHIND COLD FRONT WILL BE SOLIDLY FROM THE WEST
BOTH DAYS. WITH MODEST COLD ADVECTION THERE SHOULD BE ENOUGH MIXING
TO PRODUCE 20-25 KNOT/GUSTY IN THE OPEN ATLANTIC. MAY EVENTUALLY NEED
SCA...AT LEAST FOR WINDS.

&&

.FIRE WEATHER...NO SIG FIRE WX CONCERNS THRU FRI. BY THIS WEEKEND
...COOLER/DRIER AIR BEHIND COLD FRONT IS FORECAST TO PRODUCE MIN
RH VALUES OF 35-40 PERCENT. WEST WINDS ARE EXPECTED TO BE GUSTY
BOTH DAYS. BY MON...A MORE NORTHWEST FLOW MAY ALLOW FOR LESS AIR
MASS MODIFICATION AND RH VALUES COULD BE A LITTLE LOWER.

THIS HAZARDOUS WEATHER OUTLOOK IS FOR EAST CENTRAL FLORIDA.

.DAY ONE...THIS AFTERNOON AND TONIGHT.

...THUNDERSTORM IMPACT...
A MOIST AND UNSTABLE AIRMASS OVER FLORIDA WILL ALLOW WIDESPREAD
SHOWERS AND SCATTERED THUNDERSTORMS TO DEVELOP THROUGH THIS
EVENING. WIND PROFILES OVER THE AREA INDICATE SUFFICIENT LOW
LEVEL WIND SHEAR TO PRODUCE ROTATING STORMS THAT WILL BE CAPABLE
OF PRODUCING TORNADOES. MID AND UPPER LEVEL SUPPORT ALSO WILL AID
IN PRODUCING STRONG TO SEVERE STORMS WITH LARGE HAIL AND
DAMAGING WINDS.

A TORNADO WATCH IS IN EFFECT FOR ALL OF EAST CENTRAL FLORIDA
THROUGH 6:00 PM THIS EVENING.

...FLOOD IMPACT...
ALTHOUGH STORMS TODAY WILL MOVE NORTHEAST AT 30 TO 35 MPH...
INDIVIDUAL CELLS MAY TRAIN REPEATEDLY OVER ANY GIVEN LOCATION.
HEAVY SHORT TERM RAINFALL MAY RESULT THAT WOULD ALLOW WATER TO
POND ON STREETS...IN LOW LYING AREAS...AND THE LOW SPOTS
UNDERNEATH BRIDGES.

...MARINE THUNDERSTORM GUST IMPACT...
STRONG OFFSHORE MOVING THUNDERSTORMS OVER THE COASTAL WATERS WILL
BE CAPABLE OF PRODUCING WIND GUSTS TO 35 KNOTS.

...WATERSPOUT IMPACT...
STRONGER STORMS MAY PRODUCE FUNNEL CLOUDS AND WATER SPOUTS OVER
THE COASTAL WATERS. STORM MOVEMENT WILL BE TO THE NORTHEAST AROUND
30 KNOTS.

...WIND AND SEA IMPACT...
A MODERATE TO FRESH SOUTHERLY BREEZE WILL PRODUCE VERY ROUGH...
SHORT PERIOD SEAS OVER THE OPEN ATLANTIC TODAY. SEAS HEIGHTS OF 5
TO 7 FEET NEARSHORE AND 6 TO 8 FEET OFFSHORE CAN BE EXPECTED.

.DAYS TWO THROUGH SEVEN...FRIDAY THROUGH WEDNESDAY.
A LARGE AREA OF SHOWERS AND STORMS IS EXPECTED TO OVERSPREAD THE
AREA ON FRIDAY. SOME STORMS COULD BE STRONG TO SEVERE AND MORE
WIDESPREAD HEAVY RAIN IS EXPECTED.

GUSTY WEST WINDS WILL USHER IN DRIER AIR BEHIND A COLD FRONT EARLY
SATURDAY. MARGINALLY HAZARDOUS BOATING CONDITIONS WILL OCCUR IN
THE OPEN ATLANTIC OVER THE WEEKEND.

.SPOTTER INFORMATION STATEMENT...
SPOTTERS SHOULD MONITOR THE WEATHER. FORMAL ACTIVATION MAY BE
NEEDED.
