AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MELBOURNE FL
300 PM EDT WED JUN 25 2008

.DISCUSSION...

VERY UNSTABLE AIRMASS OVER THE AREA AS INDICATED BY A 15Z RAOB
SOUNDING FROM CAPE CANAVERAL:  H50 TEMPS BLO -10C...PW 2.0...AND A
POCKET OF RELATIVELY DRY AIR IN THE H85-H70 LYR.  EXPECT SCT/NMRS
SHRA/TSTRM ACTIVITY OVER THE CWA N OF SR-60...TRACKING N/NW THRU THE
REMAINDER OF THE AFTN.  SVR STORMS PSBL WITH FREQUENT TO EXCESSIVE
CG LTG.

CONVECTION GOT AN EARLY START THIS AFTN AND SHOULD BURN OFF MOST OF
ITS ENERGY BY 00Z.  DLM ATLC RIDGE OVER THE NRN PENINSULA WILL
GENERATE A LIGHT S/SERLY FLOW AREAWIDE.  A SLIGHT ONSHORE COMPONENT
S OF CAPE CANAVERAL COULD PUSH ISOLD SHRAS ONSHORE OVERNIGHT...WILL
KEEP SLIGHT CHANCE IN THE FCST AFT MIDNIGHT.  SFC DEWPOINTS IN THE
U60S/M70S AREAWIDE WILL KEEP MIN TEMPS IN THE L/M70S.

THU-SAT...LOW LEVEL RIDGE AXIS WILL REMAIN IN THE GENERAL VICINITY
OF CTRL FL AS H50 RIDGE STRENGTHENS A BIT EARLY ON...THEN MAINTAINS
ITSELF INTO THE FIRST HALF OF THE WEEKEND. SUFFICIENT MOISTURE WILL
EXIST FOR SCT DIRUNAL CONVECTION. STEERING WINDS WILL REMAIN WEAK...
MEANING THAT ACTIVITY WILL PROPAGATE INLAND ALONG ECSB RATHER THAN
MOVE WITH ANY SORT OF SIGNIF DIR/SPEED OF ITS OWN ACCORD. PATTERN
WILL FAVOR LATE EARLY-MID AFTN ACTIVITY OVER THE COASTAL COS AND
MID/LATE AFTN ACROSS THE INTR...PSBLY LINGERING FOR A COUPLE HRS
INTO THE EARLY EVENING..ESPEC OVER THE FAR WRN INTR. OVERALL HAVE
GONE WITH POPS ABOUT 10% HIGHER ACROSS THE INTR.

SUN-WED...LONGWAVE PTRN OVER THE CONUS BEGINS TO CHG AS LARGE MID/
UPR LOW OVER THE WRN GRT LKS RGN OPENS UP INTO A TROUGH AND DROPS
ESEWD ACROSS MOST OF THE ERN CONUS. TROUGH WILL EVENTUALLY DAMPEN
OUT AS IT WORKS ITS WAY OFFSHORE INTO THE WRN ATLC. THIS WILL
EFFECTIVELY SHUNT THE WRN EXTENT OF THE SUBTROP RIDGE BACK TWD THE
SE THROUGH TUE...WHICH IN TURN WILL CAUSE THE LOW-MID LEVEL FLOW TO
BECOME SSW/SW. BY WED...DLM RIDGE WILL START TO BUILD NWD TWD CTRL
FL AGAIN WITH MEAN FLOW BCMG MORE S-SE.

ALL IN ALL...THE NEXT SEVEN DAY FCST CYCLE WILL TRANSITION FROM
THREE DAYS WHERE THE INTR-WRN PENINSULA WILL BE FAVORED FOR DIURNAL
CONVECTION...FOLLOWED BY THREE DAYS WHERE ACTIVITY SHOULD FOCUS BACK
TWD THE CTRL-ERN SIDE OF THE PENINSULA. H50 TEMPS GENERALLY REMAIN
AOB -8C...AND OCNLY AROUND -9C/-10C. HENCE...THERE SHOULD BE A THREAT
FOR STRONG TO SVR CONVECTION ON MOST DAYS DURING THE UPCOMING WEEK.

.MARINE...ATLC RIDGE AXIS OVER THE NRN PENINSULA WILL MAINTAIN A
WEAK PGRAD OVER THE LCL ATLC WATERS OVERNIGHT.  CONDITIONS WILL
RANGE FROM   LIGHT AIR TO A LIGHT SE BREEZE N OF CAPE CANAVERAL...TO
A LIGHT/GENTLE SE BREEZE S OF THE CAPE.  SMALL ERLY SWELL GENERATED
BY A WEAK T-WAVE WILL PUSH INTO THE OFFSHORE WATERS OVERNIGHT...BUT
IMPACT WILL BE MINOR.  NEARSHORE SEAS 1-3FT...OFFSHORE SEAS 2-4FT.

THU ONWARD...RELATIVELY BENIGN WIND/WAVE CONDS EXPECT TO CONTINUE
FOR THE MOST PART AS LOW LEVEL RIDGE AXIS REMAIN OVER THE MARINE
AREA THRU SAT..THEN SHIFTS TO THE SOUTH OF THE AREA SUN/MON. WNAWAVE
GUIDANCE BUILDS SWELL TO 4-5FT OVER THE OUTER WATERS LATE TOMORROW
INTO FRIDAY...WHICH SEEMS A BIT HIGH TO ME...GIVEN THAT THE LOW
LEVEL RIDGE NEVER REALLY GETS FAR ENOUGH NORTH TO DRIVE SIGNIFICANT
ERLY SWELL INTO OUR OUTER WATERS...COUPLED WITH THE FACT THAT A GOOD
PART OF SWELL COMING FROM THE ESE-SE WILL USUALLY GET DAMPENED OUT
BY THE BAHAMA CHAIN. CONSEQUENTLY...HAVE SHAVED A GOOD FOOT OFF OF
PEAK SWELL...CAPPING SEAS @ 3-4FT OVER THE OFFSHORE WATERS FROM THU
NGT INTO THE WEEKEND...AND KEEPING SEAS IN THE 1-3FT RANGE NR SHORE.

THIS HAZARDOUS WEATHER OUTLOOK IS FOR EAST CENTRAL FLORIDA.

.DAY ONE...THIS AFTERNOON AND TONIGHT.

...THUNDERSTORM IMPACT...
CONSIDERABLE HIGH CLOUDINESS WILL EXIST ACROSS THE AREA AGAIN
TODAY BUT ENOUGH SURFACE HEATING WILL OCCUR FOR SCATTERED SHOWERS
AND THUNDERSTORMS TO FORM ALONG EAST COAST SEA BREEZE AS IT MOVES
INLAND DURING THE EARLY TO MID AFTERNOON. STORMS WILL DEVELOP
MAINLY WEST OF INTERSTATE 95...THEN WILL PUSH FURTHER INLAND
WHILE INCREASING IN COVERAGE AND INTENSITY.

COOL TEMPERATURES ALOFT WILL CONTINUE...ALLOWING SOME OF THE
STORMS ACROSS INTERIOR COUNTIES TO BECOME STRONG ONCE AGAIN.
CLOUD-TO-GROUND LIGHTNING WILL BE THE MAIN HAZARD.THOUGH A FEW
STORMS WILL BE CAPABLE OF PRODUCING HAIL AND DAMAGING WINDS...
MAINLY OVER LAKE COUNTY AND WESTERN ORANGE COUNTY.

...FLOOD IMPACT...
A FEW STRONG AND SLOW MOVING THUNDERSTORMS ACROSS INTERIOR WILL BE
CAPABLE OF PRODUCING 2 TO 3 INCH DOWNPOURS IN A SHORT PERIOD OF
TIME. THE HEAVY RAIN WILL RESULT IN PONDING OF WATER ON ROADWAYS
AND OTHER POOR DRAINAGE AREAS.

.DAYS TWO THROUGH SEVEN...THURSDAY THROUGH TUESDAY.
EXPECT AFTERNOON AND EARLY EVENING LIGHTNING STORMS EACH DAY.
COOL TEMPERATURES ALOFT WILL PRODUCE AN INCREASED RISK OF STRONG
STORMS EACH DAY.

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