EAST CENTRAL FLORIDA FORECAST DISCUSSION

CURRENTLY...CLOUD PATTERNS INDICATE THE SUBTROPICAL RIDGE AXIS
BISECTING THE FLORIDA PENINSULA. TROPICAL JET MAX OVER THE S
FLORIDA STRAITS HELPING TO ENHANCE SCATTERED RW OVER INTERIOR AND NE
PENINSULA.  DEWPOINTS IN THE 60S AND SEA SURFACE TEMPS IN THE M/U
70S...THE WET SEASON APPEARS TO BE KNOCKING ON THE DOOR.

SHORT TERM...MODELS ARE IN DECENT AGREEMENT WITH THE MOTION OF
THE BROAD LOW PRESSURE SYSTEM ACROSS NEW ENGLAND...THE GREAT
LAKES... AND THE UPPER MIDWEST.  THE SYSTEM WILL PULL A COLD FRONT
ACROSS THE MISSISSIPPI AND RED RIVER VALLEYS BEFORE IT STALLS N OF
THE PANHANDLE. THE SFC-H70 TROF WILL SUPRESS THE SUBTROPICAL RIDGE
AXIS DOWN TO THE N BAHAMAS/S FL PENINSULA.  RESULTING SW FLOW FAVORS
ABV CLIMO TEMPS FOR THE CWA...AS THE FOUS/FAN NUMBERS INDICATE.
TEMPS COULD BREAK THE 90 DEGREE MARK OVER THE SRN INTERIOR.  PW

AS SFC-H70 WINDS TURN TO THE W/NW.  MOISTURE VALUES WILL STILL HIGH
ENOUGH TO SUPPORT PRECIP...MAINLY OVER THE SOUTH.

WINDS VEERING TO THE NE ON FRI AND E/SE BY SAT...WITH MRH VALUES AT
OR BELOW 50 PERCENT.  PRECIP CHANCES TOO LOW TO MENTION IN THE

EAST CENTRAL FLORIDA HAZARDOUS WEATHER OUTLOOK
NATIONAL WEATHER SERVICE MELBOURNE FL
1215 PM EDT TUE MAY 9 2000

WIDELY SCATTERED SHOWERS AND A FEW THUNDERSTORMS ARE EXPECTED TO
DEVELOP ALONG THE EAST COAST SEA BREEZE AS IT PUSHES INLAND THIS
AFTERNOON.  ADDITIONAL STORMS WILL DEVELOP AS IT INTERACTS WITH LAKE
BREEZES AND THE WEST COAST SEA BREEZE.  ALL STORM ACTIVITY WILL MOVE
NORTHEAST AROUND 15 MPH...BRINGING SOME STORMS TOWARD THE COAST
LATE THIS AFTERNOON AND THIS EVENING.

A SLIGHTLY BETTER CHANCE FOR SHOWERS AND THUNDERSTORMS WILL OCCUR
WEST OF A LINE FROM CAPE CANAVERAL TO LAKE OKEECHOBEE...WHERE GREATER
MOISTURE EXISTS. ANY THUNDERSTORMS TODAY WILL BE CAPABLE OF PRODUCING
CLOUD TO GROUND LIGHTNING STRIKES...GUSTY WINDS UP TO 35 MPH...AND
LOCALLY HEAVY DOWNPOURS.

IN ADDITION...DUE TO CONTINUED DRY VEGETATION AND LOW RELATIVE
HUMIDITY...THERE IS A HIGH FIRE DANGER IN LAKE...WEST ORANGE...AND
NORTHWEST OSCEOLA COUNTIES.  CLOUD TO GROUND LIGHTNING MAY IGNITE
WILDFIRES IN THE VICINITY OF THUNDERSTORMS.  PREVAILING SOUTH TO
SOUTHWEST WINDS WOULD SPREAD ANY FIRES THAT DO IGNITE TO THE NORTH
AND NORTHEAST.
