AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MELBOURNE FL
156 PM EDT SAT JUN 8 2013

.DISCUSSION...
CURRENT-TONIGHT...HIGH PRESSURE RIDGING OVER THE SOUTHERN PENINSULA
WILL PUSH INTO THE CENTRAL PENINSULA INTO THE CENTRAL PENINSULA
OVERNIGHT. THIS WILL VEER BACK THE FLOW AREAWIDE TO SOUTHEAST OR
EAST-SOUTHEAST. THE 915MHZ CAPE PROFILERS CONTINUE TO SHOW
WEAKENING WINDS IN THE LOW LEVELS. THE EAST COAST SEA BREEZE
BOUNDARY WILL ADVANCE SLOWLY INLAND THROUGH LATE AFTERNOON AND
PROVIDE A FOCUS FOR INCREASING SHOWER AND STORM CHANCES. VARIOUS
MESOSCALE BOUNDARY COLLISIONS INCLUDING LATER IN THE DAY WITH THE
WEST COAST SEA BREEZE WILL ADD TO THE HIGHER THAN NORMAL EXPECTED
CONVECTIVE COVERAGE. THE MAIN THREATS REMAIN LOCALLY HEAVY DOWNPOURS
LEADING TO NUISANCE SMALL STREAM AND URBAN FLOODING IN
SPOTS...FREQUENT LIGHTNING IN A FEW CELLS AND GUSTY WINDS TO 50 MPH.

SCATTERED CONVECTION TO CONTINUE INTO LATE EVENING BUT SHOULD
DISSIPATE AREAWIDE BY MIDNIGHT. LIGHT SRLY FLOW AND BKN-OVC UPR
CLOUD DECK SHOULD KEEP MIN TEMPS IN THE L/M70S.

SUN-SUN NIGHT...THE LOW-LEVEL RIDGE AXIS WILL PUSH INTO NORTH
FLORIDA BY THE END OF THIS PERIOD. THE SURFACE FLOW WILL BE
PREDOMINANTLY EAST-SOUTHEAST OR SOUTHEAST ACROSS EAST CENTRAL
FLORIDA. PRECIPITABLE WATER VALUES WILL REMAIN OVER 2 INCHES ACROSS
MOST OF THE AREA. THE EAST COAST SEA BREEZE WILL DEVELOP
EARLIER...ESPECIALLY OVER THE TREASURE COAST...AND PUSH FURTHER
INLAND WITH A GREATER FOCUS FOR AFTERNOON/EVENING STORMS ACROSS THE
INTERIOR. EXPECT AN EARLIER INITIATION TO CONVECTION ON THIS DAY.
HIGHS IN THE MID TO UPPER 80S ALONG THE COAST AND UPPER 80S TO LOWER
90S OVER THE INTERIOR. OVERNIGHT LOWS IN THE LOWER TO MIDDLE 70S.

...PREVIOUS EXTENDED DISCUSSION...

MON-SAT...LOWER THAN NORMAL RAIN CHCS MON WITH DEEPER ONSHORE
WINDS AND SOME TEMPORARY DRYING OVER MOST OF THE AREA. INLAND
AREAS WL HAVE BEST CHC OF DIURNAL PCPN.

SUBTROPICAL RIDGE AXIS IS ADVERTISED TO BECOME SHUNTED SWD ONCE
AGAIN BY LATE TUE AS A FAIRLY DEEP UPR TROUGH MOVES ACROSS THE OH
VALLEY AND SE STATES. RAIN CHCS LOOK TO REMAIN SEASONAL INTO AT
LEAST TUE/WED DUE TO SUITABLE MOISTURE AND PRESENCE OF UPR WAVE.
SOME LOCAL DRYING IS SHOWN PAST THE MIDDLE OF THE UPCOMING WEEK AS
THE TROUGH AXIS MOVES EAST OF OUR AREA. THE WEEK LOOKS TO CLOSE
OUT WITH NEAR TO SLIGHTLY LOWER THAN NORMAL POP DUE TO SOME
DRYING...HOWEVER DLM FLOW IS WLY COMPONENT...FAVORING THE EAST
SIDE OF THE PENINSULA FOR LARGE SCALE AFTN CONVERGENCE.

THIS HAZARDOUS WEATHER OUTLOOK IS FOR EAST CENTRAL FLORIDA.

.DAY ONE...THIS AFTERNOON AND TONIGHT.

.THUNDERSTORM IMPACT...
SCATTERED TO NUMEROUS THUNDERSTORMS WILL DEVELOP ACROSS CENTRAL
FLORIDA THIS AFTERNOON. STORMS WILL MOVE EAST TO NORTHEAST AROUND
10 TO 15 MPH...PRODUCING DANGEROUS CLOUD-TO-GROUND LIGHTNING AND
GUSTY WINDS. AS STORMS APPROACH THE COAST AND ENCOUNTER THE EAST
COAST SEA BREEZE...A FEW STRONGER STORMS WILL BE POSSIBLE. THE
LIGHTNING THREAT ALONG THE COAST WILL BE PARTICULARLY HIGH EAST OF
A LINE FROM KISSIMMEE TO LAKE GEORGE...AS WELL AS CENTRAL MARTIN
COUNTY. REMEMBER...LIGHTNING CAN STRIKE WELL BEYOND THE AUDIBLE
RANGE OF THUNDER. CEASE OUTDOOR ACTIVITIES AND SEEK SHELTER
INDOORS IMMEDIATELY IF THUNDER IS HEARD.

.FLOOD IMPACT...
HEAVY RAIN FROM TROPICAL STORM ANDREA PRODUCED AS MUCH AS 4 TO 6
INCHES OF RAIN IN SOME PARTS OF EAST CENTRAL FLORIDA WITH 2 TO 4
INCH RAIN AMOUNTS COMMON. DUE TO THE SATURATED SOIL...ANY
ADDITIONAL RAINFALL FROM THUNDERSTORMS WILL LIKELY RESULT IN
MINOR FLOODING OF STREETS AND POOR DRAINAGE AREAS.

.RIP CURRENT IMPACT...
A 2 TO 3 FOOT LONG PERIOD SWELL WILL IMPACT THE EAST FLORIDA COAST
TODAY...GENERATING A LOW TO MODERATE RIP CURRENT THREAT AT AREA
BEACHES. THE THREAT WILL BE HIGHEST THROUGH THE AFTERNOON HOURS DUE
TO TIDAL EFFECTS. BEACH GOERS ARE URGED TO CHECK WITH BEACH PATROL
FOR THE LATEST CONDITIONS AND TO SWIM ONLY AT GUARDED BEACHES.

.MARINE THUNDERSTORM GUST IMPACT...
WIND GUSTS AROUND 35 KNOTS WILL BE POSSIBLE OVER THE INLAND
LAKES...INTRACOASTAL WATERWAYS AND THE ATLANTIC WITH ANY LIGHTNING
STORMS THAT DEVELOP THIS AFTERNOON. STORM MOTION TODAY WILL BE
TOWARD THE EAST TO NORTHEAST AROUND 10 TO 15 MPH.

.DAYS TWO THROUGH SEVEN...SUNDAY THROUGH FRIDAY.
SCATTERED TO NUMEROUS AFTERNOON AND EVENING LIGHTNING STORMS WILL
OCCUR ACROSS EAST CENTRAL FLORIDA INTO THE MIDDLE OF NEXT WEEK.
DEEP MOISTURE WILL LINGER ACROSS THE AREA...RESULTING IN AN
ENHANCED THREAT FOR LOCALLY HEAVY RAIN.

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