AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MELBOURNE FL
244 PM EDT THU JUN 18 2015

.DISCUSSION...
SLIGHTLY HIGHER MOISTURE LED TO A HEALTHY CUMULUS FIELD LATE THIS
MORNING AND AN EARLIER ONSET TO CONVECTION...HOWEVER...UPDRAFTS HAVING
A HARD TIME MAINTAINING THEMSELVES...EVIDENCE OF THE LIGHT WIND
FIELD...DRY AIR...AND RELATIVE STABLE CONDITIONS OVER THE FORECAST
AREA. EAST COAST SEA BREEZE WILL CONTINUE TO TREK INLAND AND
SPARK ISOLATED SHOWERS AND PERHAPS A THUNDERSTORM. BOUNDARY-
SPARKED CONVECTION WILL LIKELY CONTINUE INTO THE EVENING WITH
PERHAPS SOME ENHANCEMENT ACROSS LAKE COUNTY WHERE EAST AND WEST
COAST BOUNDARIES WILL MERGE BEFORE SUNSET. RETAINED SOME SLIGHT
CHANCE POPS AFTER SUNSET TO ACCOUNT FOR SHOWERS FROM REMNANT
BOUNDARY COLLISIONS.

FRI-SUN...REMNANTS OF BILL AND ITS ASSOCIATED TROUGH WILL BEGIN
TO CHIP AWAY AT DEEP LAYER RIDGE OVER FLORIDA AS IT MOVES TOWARDS
THE MID ATLANTIC THIS WEEKEND. SURFACE RIDGE AXIS GETS SHUNTED
EVER SO SLIGHTLY TO THE SOUTH...STILL IN THE VICINITY OF CENTRAL
FLORIDA...KEEPING WINDS GENERALLY LIGHT AND SOUTHERLY. WITH
CONTINUED GENERAL RIDGING THROUGHOUT THE TROPOSPHERE...EXPECTING
ONLY ISOLATED-SCATTERED CONVECTION ACROSS THE INTERIOR WHERE THE
BEST BOUNDARY COLLISIONS WILL TAKE PLACE. HIGHS RANGING FROM NEAR
90 ALONG THE IMMEDIATE COAST TO MID 90S ACROSS THE INTERIOR.

FROM PREVIOUS DISCUSSION...
MON-WED...WEAK SFC TROUGH ACROSS THE SOUTHEAST STATES SHIFTS SFC
RIDGE AXIS TOWARD THE SRN FL PENINSULA INTO NEXT WEEK BUT LOW LEVEL
WINDS LOOK LIGHT ENOUGH FOR SEA BREEZE TO MOVE INLAND EACH AFT WITH
BEST AFT RAIN CHANCES REMAINING OVER THE INTERIOR EACH AFT. GFS
INDICATING SOME DRIER AIR WORKING IN WHICH COULD LIMIT POPS...BUT
FOR NOW WILL KEEP CHANCE POPS UP TO 30-40% IN THE FORECAST FOR
INLAND LOCATIONS. HEAT SHOULD CONTINUE TO PERSIST WITH HIGHS IN THE
LOW 90S COAST TO MID 90S INTERIOR.

&&

.AVIATION...
COASTAL SITES VFR THROUGH TONIGHT WITH SE FLOW BEHIND SEA BREEZE.
WILL MAINTAIN VCTS ACROSS INLAND SITES WHERE INLAND MOVING SEA
BREEZE SHOULD SPARK ISOLATED/SCATTERED SHRA/TSRA.

&&

.MARINE...
TONIGHT...ENHANCED SE FLOW ALONG THE COAST BEHIND SEA BREEZE WILL
DIMINISH AFTER SUNSET AND BECOME SOUTHERLY. SLIGHT NOCTURNAL
INCREASE IN THE SOUTHERLY BREEZE IS INDICATED OFFSHORE FROM THE
CAPE NORTHWARD TO 12-15 KNOTS. STILL SEAS WILL BE AT OR BELOW 3
FEET.

FROM PREVIOUS DISCUSSION...
FRI-MON...SFC RIDGE AXIS WILL GENERALLY REMAIN IN PLACE ACROSS
CENTRAL FL THROUGH THE PERIOD. S/SW WINDS LATE IN THE NIGHT AND
EARLY MORNING WILL BECOME S/SE INTO THE AFT AS EAST COAST SEA
BREEZE DEVELOPS AND MOVES INLAND EACH AFT. WIND SPEEDS EXPECTED TO
REMAIN BELOW 15 KNOTS WITH SEAS RANGING FROM 1-3 FEET. AFT
CONVECTION OVER LAND IS EXPECTED TO REMAIN MAINLY ACROSS THE
INTERIOR WITH THREAT FOR OFFSHORE MOVING STORMS VERY LOW.

THIS HAZARDOUS WEATHER OUTLOOK IS FOR EAST CENTRAL FLORIDA.

.DAY ONE...TODAY AND TONIGHT.

.THUNDERSTORM IMPACT...
SLIGHTLY HIGHER MOISTURE IS FORECAST TODAY. THIS SHOULD ALLOW STORMS
TO FORM A LITTLE EARLIER ALONG THE INLAND MOVING EAST COAST SEA
BREEZE. STILL...MOST ACTIVITY IS EXPECTED WEST OF INTERSTATE 95.

GREATER BOUNDARY INTERACTIONS ALONG AND WEST OF INTERSTATE 4
DURING THE AFTERNOON AND EVENING SHOULD PRODUCE SCATTERED COVERAGE
AND POSSIBLY A FEW STRONG STORMS. THE MAIN HAZARD WILL BE LIGHTNING
STRIKES WHICH COULD BE FREQUENT IN A FEW OF THE INTERIOR STORMS.

.EXCESSIVE HEAT IMPACT...
HOT TEMPERATURES COMBINED WITH AVERAGE FLORIDA HUMIDITY LEVELS
WILL RESULT IN HEAT INDICES AROUND 100 AGAIN THIS AFTERNOON...
WITH VALUES BETWEEN 100 AND 105 OVER THE INTERIOR COUNTIES. STAY WELL
HYDRATED AND TAKE OCCASIONAL BREAKS IN AIR CONDITIONING IF YOU ARE
PLANNING OUTDOOR PHYSICAL ACTIVITY.

.MARINE THUNDERSTORM GUST IMPACT...
A FEW MORE AFTERNOON STORMS ARE FORECAST TODAY ALONG THE INLAND
MOVING SEA BREEZE BOUNDARIES. WIND GUSTS AROUND 40 MPH WILL BE
POSSIBLE WITH ISOLATED STORMS...ESPECIALLY ACROSS THE INTERIOR
COUNTIES.

.DAYS TWO THROUGH SEVEN...FRIDAY THROUGH WEDNESDAY.
SLIGHTLY HIGHER MOISTURE...AND WEAKENING OF MID TO UPPER LEVEL
HIGH PRESSURE RIDGE NORTH OF THE REGION...SHOULD ALLOW FOR
SCATTERED AFTERNOON STORMS THROUGH THE WEEKEND...MAINLY OVER
INLAND COUNTIES.

HIGH TEMPERATURES WILL STILL REACH THE MID 90S OVER THE CENTRAL
FLORIDA INTERIOR THROUGH EARLY NEXT WEEK...WITH MAXIMUM HEAT INDEX
VALUES CONTINUING TO REACH 100 TO 105 DEGREES.

.SPOTTER INFORMATION STATEMENT...
SPOTTER ACTIVATION IS NOT ANTICIPATED TODAY.

LOCATIONS IMPACTED INCLUDE...
EUSTIS...MOUNT DORA...CASSIA...PAISLEY AND MOUNT PLYMOUTH.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

THE PRIMARY THREATS WILL BE CLOUD TO GROUND LIGHTNING AND STRONG WIND
GUSTS...WHICH CAN CAUSE UNSECURED OBJECTS TO BLOW AROUND...SNAP TREE
LIMBS...CAUSE POWER OUTAGES OR CAPSIZE SMALL BOATS. HEAVY RAINFALL
WILL TEMPORARILY REDUCE VISIBILITY. SEEK SHELTER INDOORS UNTIL THE
STORM PASSES.

BOATERS SHOULD BE AWARE THAT STRONG WIND GUSTS SOMETIMES OCCUR WELL
AWAY FROM THE HEAVY RAIN AND LIGHTNING ASSOCIATED WITH STORMS.

HEAVY RAINFALL IS ALSO OCCURRING WITH THIS STORM...WHICH WILL REDUCE
VISIBILITY AND MAY LEAD TO TEMPORARY FLOODING OF LOW LYING AND POOR
DRAINAGE AREAS. DO NOT DRIVE YOUR VEHICLE THROUGH FLOODED ROADWAYS.

FREQUENT CLOUD TO GROUND LIGHTNING IS OCCURRING WITH THIS STORM.
LIGHTNING CAN STRIKE SEVERAL MILES AWAY FROM A THUNDERSTORM. SEEK
SHELTER INSIDE A BUILDING OR VEHICLE. OPEN SHELTERS FOUND IN PARKS...
