AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MELBOURNE FL
245 PM EDT SAT JUN 9 2012

.DISCUSSION...

CURRENT/TONIGHT...AFTERNOON CONVECTION GOT A LITTLE BIT OF A LATE
START...HOWEVER LOCAL 88D'S SHOW DECENT PROLIFERATION OF DIURNAL
SHOWERS AND SOME STORMS...AND EXPECT THIS TREND TO CONTINUE THROUGH
LATE AFTERNOON AND THROUGH SUNSET BY A COUPLE HRS. WHILE ECSB WILL
CONTINUE TO SLIDE WWD/INLAND...STEERING FLOW WILL TRY AND PUSH
ACTIVITY BACK TOWARD THE EAST COAST. KEPT SCT EVENING POPS FOR
ALL ZONES...WITH A LITTLE BETTER CHANCE ACROSS TH NORTH CLOSER TO
BETTER POOLED MOISTURE INVOF FRONTAL BOUNDARY.

SUN-TUE...DEEP LAYER MEAN HIGH PRESSURE RIDGE BUILDS OVER THE STATE
SUN-MON...WHICH LEADS TO AN OVERALL DRYING TREND AND PROGRESSIVELY
LOWER POPS BOTH DAYS COMPARED TO THIS PAST WEEK - 30-40 ON SUN...AND
20-30 MON - ALONG THE INLAND MOVING EAST COAST SEA BREEZE. WEAKER
MEAN STEERING FLOW WILL KEEP HIGHEST RAIN CHANCES INLAND BY LATE
AFTERNOON AFTER EARLIER DEVELOPMENT CLOSER TO THE COAST/LAKE OKEE.
AFTER INITIALLY LIFTING BODILY NORTHWARD...THE REMNANT BASE OF THE
PERSISTENT CENTRAL GOMEX MID LEVEL TROUGH WILL FINALLY DRIFT
EASTWARD ACROSS THE SE CONUS/NORTH FL BY TUE.. THIS WILL CAUSE THE
LOW LEVEL RIDGE AXIS TO DRIFT SOUTH INTO CENTRAL FL...ACCOMPANIED
BY SLIGHT MOISTENING TREND/HIGHER POPS...ESPECIALLY NORTH. OVERALL
TEMPS IN THE SHORT RANGE WILL RUN NEAR CLIMO...HIGHS IN THE L90S
INLAND...U80S NEAR THE COAST.

WED-FRI (MODIFIED PREV)...MID LEVEL TROUGHINESS WILL LINGER FROM THE
CENTRAL-ERN GOMEX ACROSS FL FROM MID-LATE WEEK WITH LOW LEVEL RIDGE
AXIS SUPPRESSED OVER SOUTH FLORIDA. SYNOPTICALLY...THE PATTERN LOOKS
LIKE A WEAKER/DRIER VERSION OF WHAT WE HAD FOR MOST OF THIS PAST
WEEK. FCST CONTINUES TO INDICATE MAINLY SCATTERED COVERAGE THROUGH
THE TIME FRAME. DAYTIME HIGHS L90S INLAND (FEW M90S POSSIBLE) AND
U80S TO AROUND 90F NEAR THE EAST COAST.

&&

.AVIATION...PUSHED BACK TIMING OF PRECIP BY 1-2 HRS AT ALL SITES
GIVEN THE DELAYED ONSET OF DIURNAL STORMS. OTHERWISE...EXPECT
ACTIVITY WILL BE WINDING DOWN AROUND 01Z-02Z...WITH VFR CONDS
DEVELOPING OVERNIGHT.

&&

.MARINE...

SUN-THU...SURFACE RIDGE AXIS WILL GRADUALLY DRIFT SOUTHWARD ACROSS
THE CENTRAL PENINSULA DURING THE EARLY TO MID WEEK. THIS WILL
PRODUCE GENERALLY E-SE WINDS AOB 10KT AND SEAS AOB 2-3 FT THROUGH
THE PERIOD.

THIS HAZARDOUS WEATHER OUTLOOK IS FOR EAST CENTRAL FLORIDA.

.DAY ONE...TODAY AND TONIGHT.

.THUNDERSTORM IMPACT...
THE WEAK FRONTAL BOUNDARY IN PLACE ACROSS CENTRAL FLORIDA WILL
SLOWLY DISSIPATE TODAY. HOWEVER A VERY MOIST ATMOSPHERE WILL
REMAIN IN PLACE...LEADING TO NUMEROUS SHOWERS AND SCATTERED
EMBEDDED LIGHTNING STORMS. LIGHT WINDS IN THE PRESENCE OF THE
FRONT WILL ALLOW FOR THE DEVELOPMENT OF THE EAST COAST SEA
BREEZE...WHICH WILL PROVIDE AN ADDITIONAL FOCUS FOR SHOWER AND
STORM DEVELOPMENT. ACTIVITY WILL MOVE TO THE EAST AT 10 MPH OR
LESS. THE MAIN STORM HAZARDS WILL BE FREQUENT CLOUD TO GROUND
LIGHTNING STRIKES...VERY HEAVY DOWNPOURS AND GUSTY WINDS TO 40
MPH.

.FLOOD IMPACT...
TRAINING OF SHOWERS AND STORMS ACROSS THE SAME LOCATION WILL BE
POSSIBLE AGAIN TODAY. IN ADDITION...LIGHT STEERING FLOW WILL MEAN
THAT STORMS WILL REMAIN OVER A SINGLE LOCATION FOR A LONGER TIME
THAN EARLIER THIS WEEK. LOCAL RAINFALL AMOUNTS OF 2 TO 3 INCHES
ARE POSSIBLE...WHICH WOULD PRODUCE TEMPORARY FLOODING SOME ROADS
AND IN POOR DRAINAGE AREAS.

.MARINE THUNDERSTORM GUST IMPACT...
SHOWERS AND STORMS TODAY WILL MOVE TO THE EAST AROUND 10 KNOTS
ACROSS LOCAL LAKES...THE INTRACOASTAL AND LOCAL ATLANTIC. A FEW
STRONG STORMS WILL BE CAPABLE OF PRODUCING GUSTY WINDS TO 35
KNOTS.

.DAYS TWO THROUGH SEVEN...SUNDAY THROUGH FRIDAY.
HIGHER MOISTURE LEVELS ACROSS THE REGION WILL DIMINISH ON
SUNDAY...LEADING TO COVERAGE OF SHOWERS AND STORMS NEAR SEASONAL
NORMALS THROUGH NEXT WEEK.

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