What was reported inside it

Time	Report	Where	Remark
Jun 30, 8:47 PM EDT	TSTM WND GST 42	Vero Beach Airport, FL	THE ASOS AT THE VERO BEACH AIRPORT RECORDED A 37-KNOT/42-MPH WIND GUST OUT OF THE WEST NORTHWEST AS A THUNDERSTORM MOVED OVER THE SITE.

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, 0.6 hours before the alert went out and 98 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.

Area forecast discussion, Jun 30, 2:59 PM EDT, 5 hours 38 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MELBOURNE FL
259 PM EDT TUE JUN 30 2015

.DISCUSSION...

CURRENTLY-TONIGHT...DRIER AIR ALOFT THAT WAS EVIDENT IN THE MORNING
SOUNDING FROM TAMPA HAS KEEP CONVECTION LIMITED SO FAR THIS AFT AS
IT HAS SPREAD EASTWARD. HRRR MODEL STILL INDICATING SOME INCREASE IN
SHOWERS AND STORMS BUT COVERAGE SHOULD STILL REMAIN ON THE LOWER
END WITH BEST CHANCE FOR RAIN ALONG THE COAST INTO LATE AFT AND
SUNSET. THIS WILL BE ESPECIALLY TRUE WHERE BOUNDARY COLLISIONS
OCCUR ALONG THE STALLED EAST COAST SEA BREEZE SOUTH OF THE CAPE.
ANY PRECIP WILL PUSH OFFSHORE INTO THE EARLY EVE WITH RAIN CHANCES
ENDING FOR THE REST OF THE NIGHT. OVERNIGHT LOWS WILL RANGE FROM
THE LOW TO MID 70S WITH SKIES MOSTLY CLEAR TO PARTLY CLOUDY.

WED...MID LEVEL TROUGH OVER THE EASTERN U.S. WILL KEEP ATL RIDGE
AXIS SOUTH OF THE AREA WED. MODELS SHOW LOW LEVEL OFFSHORE FLOW
WEAKENS...WHICH SHOULD ALLOW THE EAST COAST SEA BREEZE TO FORM ALONG
MUCH OF THE COAST. HOWEVER IT WILL STILL LIKELY BE DELAYED WITH
LITTLE INLAND MOVEMENT EXPECTED...ESPECIALLY FROM THE CAPE
NORTHWARD. MOS POPS VARY FOR TOMORROW WITH GFS/MAV GUIDANCE THE
DRIER OUTLIER FROM THE NAM AND ECMWF MOS. LOOKS LIKE THERE SHOULD BE
SUFFICIENT MOISTURE AND INSTABILITY FOR ISO-SCT SHOWER/STORM
COVERAGE IN THE AFT SO HAVE LEANED TOWARD THE LATTER GUIDANCE WITH
POPS RANGING FROM 30-40 PERCENT. BEST CHANCE FOR BOUNDARY COLLISIONS
AND ANY STRONGER STORMS WILL BE OVER THE INTERIOR AND TOWARD THE
BREVARD/VOLUSIA COASTS. HIGHS FORECAST IN THE LOW 90S ACROSS THE
COAST TO MID 90S OVER THE INTERIOR.

PREVIOUS EXTENDED DISCUSSION...

THU-FRI...SUBTROPICAL RIDGE IS SHOWN BY GFS DRIFTING NWD TO A
POSITION NR CENTRAL FL BY THU A LIGHTER WIND REGIME WL LEAD TO MORE
TYPICAL COVERAGE OF AFTERNOON STORMS...SLIGHTLY DELAYED FOR ONSET
DUE TO THE NEED FOR SFC HEATING AND BOUNDARY CONDITIONS TO INITIATE
ACTIVITY. THE WEAK WIND PROFILE THU-FRI WL FAVOR INTERIOR SECTIONS
GENERALLY FOR BEST COVERAGE.

SAT-MON...THE AXIS OF THE SUBTROPICAL RIDGE IS SHOWN DRIFTING NEAR
TO JUST NORTH OF THE AREA DURING THE WEEKEND. MARINE BASED SHOWERS
ARE POSSIBLE BY SAT NIGHT/SUN WITH AT LEAST SEASONALLY TO LOW END
SCT COVERAGE AREAWIDE A GOOD BET INTO EARLY NEXT WEEK.

&&

.AVIATION...STORM COVERAGE HAS REMAINED LIMITED DUE TO DRIER AIR
ALOFT ACROSS THE REGION. MAY STILL SEE ISO-SCT SHRA/TSRA MAINLY
TOWARD THE COAST INTO LATE AFT/EARLY EVE...ESPECIALLY WITH BOUNDARY
COLLISIONS FROM KVRB-KSUA. ANY CONVECTION THAT FORMS WILL DIMINISH
AND PUSH OFFSHORE BY LATE EVE WITH RAIN CHANCES ENDING ACROSS THE
AREA.

ISO/SCT AFT SHRA/TSRA FORECAST FOR TOMORROW AFT. SEA BREEZE SHOULD
BE ABLE TO FORM ALONG MUCH OF THE COAST DUE TO A WEAKER OFFSHORE
FLOW. GREATEST STORM COVERAGE EXPECTED WITH ANY BOUNDARY
INTERACTIONS ACROSS THE INTERIOR AND TOWARD THE VOLUSIA/BREVARD
COASTS LATER IN THE DAY.

&&

.MARINE...

TONIGHT...RIDGE AXIS SOUTH OF THE AREA WILL MAINTAIN WINDS OUT OF
THE SOUTHWEST OVERNIGHT UP TO 10-15 KNOTS WITH SEAS RANGING FROM 1-3
FEET. A FEW OFFSHORE MOVING STORMS WILL CONTINUE TO BE POSSIBLE INTO
THE EVENING HOURS.

WED-SAT...(PREVIOUS DISCUSSION) THE RIDGE AXIS SITUATED JUST S OF
THE AREA THROUGH MIDWEEK WL PROVIDE FAVORABLE MARINE CONDS DUE TO
WLY COMPONENT WITH A LIMITED SEA BREEZE POTENTIAL. STORMS MOVING
OFFSHORE FROM THE MAINLAND WL PRODUCE LOCALLY HIGHER WINDS AND SEAS
IN THE AFTERNOON TO EARLY EVENING HOURS WED-THU.

THIS HAZARDOUS WEATHER OUTLOOK IS FOR EAST CENTRAL FLORIDA.

.DAY ONE...TODAY AND TONIGHT.

.THUNDERSTORM IMPACT...
WESTERLY MID LAYER WINDS WILL ALLOW SCATTERED STORMS TO MOVE EAST
FROM THE INTERIOR TOWARD THE EAST COAST IN THE AFTERNOON. THE EAST
COAST SEA BREEZE WILL ALSO DEVELOP AND MOVE SLOWLY INLAND SOUTH OF
CAPE CANAVERAL WHICH MAY ALLOW A FEW STORMS TO BECOME STRONG NEAR
THE COAST IN THE MID TO LATE AFTERNOON. STRONGER STORMS TODAY MAY
PRODUCE WIND GUSTS TO 50 MPH...LOCALLY HEAVY RAIN AND FREQUENT
LIGHTNING.

.MARINE THUNDERSTORM GUST IMPACT...
A FEW STRONGER STORMS APPROACHING THE INTRACOASTAL AND NEAR SHORE
ATLANTIC WATERS THIS AFTERNOON WILL BE CAPABLE OF PRODUCING WIND
GUSTS IN EXCESS OF 40 KNOTS. A FEW STRONGER STORMS OVER THE
INTERIOR MAY ALSO PRODUCE STRONG AND GUSTY WINDS. BOATERS ARE
URGED TO KEEP AN EYE TO THE WESTERN SKIES FOR APPROACHING WEATHER
AND TO SEEK SAFE HARBOR BEFORE THE STORMS ARE IN YOUR AREA.

.RIP CURRENT IMPACT...
WEATHER AND OCEAN CONDITIONS WILL PRODUCE A LOW TO MODERATE RISK
OF RIP CURRENTS AT THE BEACHES OF EAST CENTRAL FLORIDA THIS
AFTERNOON. ALWAYS SWIM WITHIN SIGHT OF A LIFEGUARD.

.DAYS TWO THROUGH SEVEN...WEDNESDAY THROUGH MONDAY.
SCATTERED LIGHTNING STORMS ARE FORECAST EACH AFTERNOON THROUGH
THE HOLIDAY WEEKEND...WITH THE POTENTIAL FOR THUNDERSTORMS TO MOVE
OFFSHORE DURING THE LATE AFTERNOONS AND EARLY EVENINGS INTO MID
WEEK. THE PRIMARY THREATS WILL BE FREQUENT CLOUD TO GROUND
LIGHTNING AND GUSTY DOWNBURST WINDS.

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