AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MELBOURNE FL
953 AM EDT WED MAY 25 2005

.DISCUSSION...
FRONTAL BOUNDARY DENOTED AS A CLOUD LINE FROM ABOUT NEW PORT RICHEY
TO WINTER HAVEN...KENANSVILLE AND SEBASTIAN INLET...THEN EASTWARD
OVER THE ATLANTIC AS OF 930 AM.  BOUNDARY SLOWING DOWN...WITH
WESTERN PORTION LOOKING LIKE IT IS BECOMING NEARLY STATIONARY. AIR
MASS IS DRYING OVER NORTHERN PORTION OF AREA WITH DAYTONA BEACH DEW
POINT DOWN TO 59.

VORT MAX MOVING SOUTHEAST NEAR THE MISSISSIPPI DELTA LOOKS LIKE IT
IS HELPING TO FIRE CONVECTION ALONG/JUST NORTH OF THE BOUNDARY IN
THE NORTHEAST GULF OF MEXICO.

FORECAST FOR TODAY IS A TRICKY ONE BUT WILL ADJUST POPS DOWN IN THE
NORTH HALF...FIGURING THAT CONVECTIVE INITIATION WILL BE CLOSE TO
THE BOUNDARY AND DRYING IN THE NORTH WILL LIMIT CHANCES TO 20
PERCENT OR LESS.  CONVECTION THAT DOES DEVELOP IN THE SOUTH HALF
WILL HAVE VERY MOIST LOW LEVELS WITH SURFACE DEW POINTS IN THE
LOW/MID 70S.  MID LEVEL DRY AIR AND TEMPS STILL AROUND MINUS 10 AT
500 MB SHOULD SUPPORT ISOLATED STRONG TO SEVERE STORMS.

&&

.AVIATION...HIGH SURFACE DEW POINTS WILL RESULT IN SOME RATHER LOW
BASED CU FORMATION AS THE EARLY MORNING STRATUS LIFTS.  STORMS THIS
AFTERNOON SHOULD MAINLY BE IN THE MOISTURE RICH ZONE SOUTH OF
ORLANDO AND MELBOURNE...WHERE IFR VISIBILITIES AND LOCAL IFR
CEILINGS WILL BE POSSIBLE IN ISOLATED STRONG STORMS.

&&

.MARINE...LATEST JAX OFFSHORE...BEYOND 20NM...BUOY RECORDING N TO
NNE AROUND 15 KNOTS WITH 6 FOOT SEAS. BUOY 009 WAS RECORDING NNE
8-10 KNOTS AND 2 FOOT SEAS...WITH OVERALL APPEARANCE THAT THE WIND
SURGE IS WEAKENING...SO PLANNING ON DROPPING EXERCISE CAUTION
STATEMENT IN THE SOUTH LEG.

NORTH WINDS DOWN THE LENGTH OF THE INDIAN RIVER LAGOON WILL GENERATE
CHOPPY CONDITIONS IN OPEN AND WINDWARD FACING AREAS OF THE
INTRACOASTAL WATERWAY. WILL ADJUST OFFSHORE SEA GRIDS TO SHOW
NORTHERLY WINDS PUSHING SEAS HIGHER IN AND NEAR THE GULF STREAM FOR
THE AFTERNOON HOURS.

&&

615 AM EDT WED MAY 25 2005

THIS HAZARDOUS WEATHER OUTLOOK IS FOR EAST CENTRAL FLORIDA.

.DAY ONE...TODAY AND TONIGHT...

...THUNDERSTORM IMPACT...
THE COMBINATION OF SUFFICIENT LOW LEVEL MOISTURE...LOCAL SEA AND
LAKE BREEZE BOUNDARIES...AND WEAK LOW PRESSURE FORMING ALONG A COLD
FRONT WHICH IS MOVING INTO THE AREA...WILL RESULT IN SCATTERED
AFTERNOON LIGHTNING STORMS TODAY. THE PRESENCE OF AN UPPER LEVEL
DISTURBANCE MOVING OVERHEAD TODAY WILL YIELD A SUFFICIENTLY
UNSTABLE ATMOSPHERE FOR SOME OF THE STORMS TO BECOME STRONG TO
SEVERE THIS AFTERNOON. LARGE HAIL...DAMAGING WIND GUSTS...AND EVEN
AN ISOLATED TORNADO... WILL BE POSSIBLE IN SOME OF THE STRONGER
STORMS.

CLOUD TO GROUND LIGHTNING IS FLORIDAS NUMBER ONE WEATHER RELATED
KILLER. AS WAS SEEN YESTERDAY IN THE CASE OF AN OUTDOOR WORKER WHO
WAS STRUCK AND INJURED...LIGHTNING CAN OCCUR WELL AHEAD OF THE RAIN
ASSOCIATED WITH STORMS. SEEK SHELTER WELL IN ADVANCE OF STORMS.

...MARINE THUNDERSTORM GUST AND WATERSPOUT IMPACTS...
STORMS WILL MOVE RAPIDLY EAST AT AROUND 30 MPH...WHICH MEANS THEY
WILL AFFECT THE ADJACENT ATLANTIC WATERS AS WELL. DEADLY CLOUD TO
WATER LIGHTNING...GUSTY WINDS...LOCALLY CONFUSED SEAS...AND HAIL
MAY OCCUR WITH THE MORE INTENSE MARINE STORMS. ISOLATED
WATERSPOUTS MAY ALSO OCCUR...MAINLY NEAR THE COAST.

...WIND AND SEA IMPACT...
MODERATELY STRONG WESTERLY WINDS WILL TURN TO THE NORTH AS THE FRONT
SWEEPS ACROSS THE ATLANTIC WATERS TODAY. SINCE INCREASING WINDS AND
SEAS ARE EXPECTED...SMALL CRAFT SHOULD EXERCISE CAUTION TODAY.

.DAYS TWO THROUGH SEVEN...THURSDAY THROUGH NEXT TUESDAY...
AFTERNOON AND EVENING LIGHTNING STORMS ARE EXPECTED TO INCREASE THIS
WEEKEND AS THE FLORIDA WEATHER PATTERN GRADUALLY SHIFTS INTO ITS
RAINY SEASON.

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