AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MELBOURNE FL
245 PM EDT TUE AUG 4 2009

.DISCUSSION...

NOW-WEDNESDAY...WEATHER PATTERN FOR THE REST TODAY INTO WEDNESDAY
WILL CHANGE LITTLE...CONTINUING TO BE DOMINATED BY THE POSITION OF
THE SUBTROPICAL RIDGE AXIS. ACTIVITY HAS BEEN A LITTLE LATER TO
INITIATE THAN ON MONDAY...BUT BOTH SEA BREEZES HAVE DEVELOPED AND
ARE CURRENTLY MARCHING INLAND. SHOWERS AND STORMS WILL QUICKLY
INCREASE IN COVERAGE OVER THE NEXT FEW HOURS WITH THE HIGHEST
COVERAGE EXPECTED OVER THE ORLANDO METRO AND ALONG THE ST JOHNS
RIVER BASIN SIMILAR TO YESTERDAY WITH STORMS DRIFTING BACK TOWARDS
THE COAST.

STEERING FLOW REMAINS LIGHT AND SLOW MOVING STORMS WILL BE ABLE TO
PRODUCE ANOTHER ROUND OF TORRENTIAL DOWNPOURS WITH LOCALIZED MINOR
STREET AND URBAN FLOODING THROUGH THE EVENING. OUTFLOW BOUNDARY/SEA
BREEZE COLLISIONS WILL CONTINUE ACTIVITY THROUGH THROUGH THE LATE
EVENING HOURS. A FEW STRONG STORMS WILL BE POSSIBLE WITH ANY
BOUNDARY INTERACTIONS WITH FREQUENT LIGHTNING...POSSIBLE FUNNEL
CLOUDS...STRONG GUSTY WINDS IN ADDITION TO THE HEAVY RAINS.

WITH THE WEAK UPPER LEVEL TROUGH ACROSS THE SOUTHEAST FILLING
IN...THE SURFACE RIDGE AXIS WILL CONTINUE TO CREEP NORTH KEEPING IT
RIGHT OVER OR JUST NORTH OF CENTRAL FLORIDA THROUGH WEDNESDAY.
SOUTHWESTERLY FLOW LOOKS TO EASE OVERNIGHT AS THE RIDGE AXIS MOVES
NORTH...ALLOWING DEEPER S-SE FLOW OVER THE REGION. THIS WILL PUSH
THE MAIN FOCUS OF AFTERNOON STORMS ON WEDNESDAY A LITTLE MORE INLAND
THAN TODAY OR YESTERDAY...WITH A LITTLE HIGHER COVERAGE. HAVE KEPT
THE POPS OVER THE INTERIOR AT 60 PERCENT FOR WEDNESDAY AND A
GRADIENT FROM 30 PERCENT OVER THE FAR SOUTH WHERE THE SEA BREEZE
WILL PUSH INLAND THE QUICKEST TO 50 PERCENT OVER THE REST OF THE
INTERIOR AND NORTHERN COAST.

THU...12Z GFS CONTINUES TREND OF PREV MODEL RUNS SHOWING A SURGE IN
THE SOUTHEASTERLIES AND DEEPER MOISTURE MOVING OVER THE AREA
ASSOCIATED WITH THE NRN EXTENSION ON A WEAK EASTERLY WAVE. NAM
REMAINS SLOWER WITH DEEPER MOISTURE MAINLY AFFECTING S FL. APPEARS
NRN AND INTERIOR AREAS WILL BE FAVORED FOR AFTERNOON CONVECTION WITH
POSSIBLE MORNING ACTIVITY ALONG THE MARTIN COUNTY COAST AS ESE/SE
FLOW INCREASES THROUGH THE DAY.

FRI...MDT ESE/SE LOW LVL FLOW AROUND THE ATLC RIDGE AND BUILDING H5
HTS EAST OF THE STATE WITH SLIGHTLY BELOW NORMAL PWATS 1.7 SHOULD
LEAD TO A LOWER COVERAGE OF SHOWERS AND STORMS WITH MUCH OF THE
ACTIVITY DEVELOPING IN THE AFTERNOON ACROSS INTERIOR AND SRN
SECTIONS.

SAT/SUN...BUILDING MID LVL RIDGE IS FORECAST ACROSS N FL AND THE SE
STATES THIS WEEKEND WITH SE FLOW AT THE LOW LVLS AND NE FLOW ALOFT.
DRYING FROM THE MID LVL ANTICYCLONE SHOULD REDUCE POPS TO BELOW
CLIMO RANGES OVER THE WEEKEND WITH ACTIVITY MAINLY DEVELOPING OVER
THE INTERIOR AND PROGRESSING TWD THE WRN SIDE OF THE PENINSULA IN
THE LATE AFTN AND EARLY EVENING. HIGHS SHOULD BE AROUND 90 AT THE
COAST TO THE MID 90S OVER THE INTERIOR. WITH PLENTY OF SUNSHINE AND
HOT TEMPS EXPECTED AT THE BEACHES FOR THE UPCOMING WEEKEND WILL HAVE
TO WATCH OUT FOR AN ENHANCED RIP CURRENT RISK WITH THE WAVEWATCH
MODEL PICKING UP ON A 3-4 FT SWELL FROM THE EAST AT BUOY 41009
SAT-SUN.

MON/TUE...H5 RIDGE ACROSS THE SE STATES BEGINS TO BREAK DOWN WITH
MOISTURE LEVELS BEGINNING TO CREEP BACK UP. STILL LOOKS LIKE
INTERIOR AND THE WRN SIDE OF THE PENINSULA WILL BE FAVORED FOR
DIURNAL STORMS WITH PREVAILING LIGHT ONSHORE FLOW IN THE LOW LVLS.
NO CHANGES MADE TO DAY

&&

.AVIATION...
SCT SHRA/TSRA ACROSS ENTIRE REGION WITH TEMPO IFR/MVFR  CONDS.
HIGHEST STORM COVERAGE EXPECTED TO BE AGAIN THROUGH KDAB-KMCO-KOBE
WITH EAST-WEST COAST SEA BREEZE COLLISION AROUND 22Z-02Z.
PREVAILING VFR WITH DIMINISHING MID AND HIGH DEBRIS CLOUDS AFTER
03Z.

&&

.MARINE...

TONIGHT-WEDNESDAY...S/SE FLOW AT 5-10 KTS WILL PREVAIL THROUGH
WEDNESDAY UNDER A WEAK HIGH PRESSURE RIDGE AXIS STRETCHED OVER THE
AREA. SEAS WILL BE AOB 2-3 FT. WEAK WESTERLY STEERING FLOW MAY BE
ABLE TO PUSH A  FEW STORMS OFFSHORE MAINLY ALONG THE VOLUSIA/N
BREVARD COUNTY COASTS LATE THIS AFTERNOON/EVENING. THREAT FOR
OFFSHORE MOVING THUNDERSTORMS WILL DIMINISH AS STEERING FLOW SHIFTS
MORE FROM THE S-SE.

THU-SUN...ESE/SE SFC WINDS WILL CONTINUE TO 10-15 KNOTS THROUGH THE
5 DAY FORECAST. SOME INCREASE IN THE FLOW AND ENHANCED TSTM CHCS MAY
OCCUR THU WITH THE NRN EXTENSION OF AN EASTERLY WAVE MAINLY
AFFECTING THE WATERS SOUTH OF FPR INLET. SEAS BUILDING TO 3-4 FT
OFFSHORE IN AN EAST SWELL THU-SAT.

THIS HAZARDOUS WEATHER OUTLOOK IS FOR EAST CENTRAL FLORIDA.

.DAY ONE...TODAY AND TONIGHT.

...THUNDERSTORM IMPACT...
AMPLE MOISTURE...NUMEROUS BOUNDARY INTERACTIONS AND AFTERNOON
HEATING WILL LEAD TO THE DEVELOPMENT OF SCATTERED LIGHTNING
STORMS. ISOLATED TO SCATTERED STORMS WILL INITIALLY DEVELOP ALONG
THE EAST COAST SEA BREEZE BOUNDARY EARLY THIS AFTERNOON. HIGHEST
STORM COVERAGE WILL THEN OCCUR LATE IN THE DAY OVER THE INTERIOR
AND VOLUSIA AND BREVARD COUNTY COAST DURING COLLISIONS OF SEA
BREEZE AND STORM OUTFLOW BOUNDARIES. A FEW STRONG STORMS WILL BE
POSSIBLE WITH THE MAIN THREATS BEING FREQUENT CLOUD TO GROUND
LIGHTNING...STRONG WIND GUSTS...AND TORRENTIAL DOWNPOURS.

...FLOOD IMPACT...
WEAK WINDS THROUGH THE LOWER ATMOSPHERE WILL LEAD TO VERY SLOW
STORM MOTION. STRONGER STORMS WILL BE ABLE TO PRODUCE HEAVY
RAINFALL AMOUNTS UP TO 2 TO 4 INCHES...ESPECIALLY THOSE STORMS
THAT FORM DUE TO BOUNDARY COLLISIONS OVER THE INTERIOR LATE TODAY.
THIS AMOUNT OF RAINFALL CAN PRODUCE MINOR FLOODING OF URBAN...LOW
LYING...AND POOR DRAINAGE AREAS.

...MARINE THUNDERSTORM GUST IMPACT...
WEAK WESTERLY STEERING FLOW FROM CENTRAL BREVARD COUNTY NORTHWARD WILL
PRODUCE A LOW THREAT FOR OFFSHORE MOVING THUNDERSTORMS...MAINLY
ALONG THE VOLUSIA AND NORTH BREVARD COUNTY COASTLINE. FREQUENT
CLOUD TO WATER LIGHTNING STRIKES AND WIND GUSTS TO AROUND 35 KNOTS
WILL BE POSSIBLE WITHIN THE STRONGEST STORMS.

...WATERSPOUT IMPACT...
A BRIEF FUNNEL CLOUD OR WATERSPOUT WILL BE POSSIBLE AT THE COAST
AND INTRACOASTAL WATERS MAINLY LATE THIS MORNING AND EARLY
AFTERNOON DURING THE INITIAL VIGOROUS GROWTH PHASE IN DEVELOPING
STORMS. CONDITIONS FOR THIS ARE HISTORICALLY HIGHER OVER THE
INTRACOASTAL WATERS AND MERRITT ISLAND AS THE EAST COAST SEA
BREEZE BOUNDARY MOVES INLAND.

.DAYS TWO THROUGH SEVEN...WEDNESDAY THROUGH MONDAY.
HIGH PRESSURE RIDGE AXIS WILL REMAIN FIXED ACROSS THE CENTRAL
FLORIDA PENINSULA THROUGH THIS WEEK THEN DRIFTING NORTH TOWARD THE WEEKEND.
SCATTERED STORMS WILL DEVELOP EACH AFTERNOON WITH GREATEST CHANCES OCCURRING
WITH ANY SEA BREEZE BOUNDARY INTERACTIONS OVER THE INTERIOR.

.SPOTTER INFORMATION STATEMENT...

SPOTTER ACTIVATION IS NOT ANTICIPATED TODAY.
