AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TALLAHASSEE FL
130 PM EDT SAT MAY 13 2000

MODELS/ZFP: SHORT RANGE MODELS IN FAIRLY GOOD AGREEMENT WITH AROUND
A 06 UTC FRONTAL PASSAGE EXPECTED FOR THE FCST AREA. THIS FRONT HAS
BEEN PROGRESSIVELY WEAKENING AS IT APPROACHES THE PROTECTING SFC
HIGH PRESSURE RIDGE WHICH EXTENDS FROM OFF OF THE EAST COAST OF
FLORIDA INTO THE EASTERN GULF OF MEXICO. WHERE THE MODELS DIFFER IS
IN THE MOISTURE FIELDS...WITH THE NGM AND AVN TRYING TO SQUEEZE OUT
SOME PRECIP OVER THE AREA OVERNIGHT...AND THE ETA SHOWING A
VIRTUALLY DRY COLD FRONTAL PASSAGE. HOWEVER...THE ETA FCST SOUNDING
FOR TLH SHOWS A SIGNIFICANT INCREASE IN MOISTURE TONIGHT WITH PWS
APPROACHING 1.5 INCHES ALONG WITH SOME MID-LEVEL COOLING. THE
MISSING INGREDIENTS APPEAR TO BE LOW LEVEL FORCING AND UPPER LEVEL
SUPPORT...BUT WITH THE INCREASE IN LOW LEVEL MOISTURE AND
INSTABILITY...FEEL MORE THAN JUSTIFIED TO INCORPORATE SLIGHT CHANCE
POPS ACROSS THE BOARD FOR TONIGHT. AFTER THE FRONT PASSES
THROUGH...MUCH DRIER AIR BUT CONTINUED QUITE WARM TEMPERATURES WILL
PREVAIL.

MARINE: WINDS SHOULD PICK UP OUT OF THE WEST TONIGHT BEFORE SHIFTING
TO THE NORTH TOMORROW MORNING. AT THIS TIME...DONT SEE THE STRENGTH
IN THE CURRENT WIND FIELD OR SFC PRESSURE GRADIENT TO REQUIRE ANY
FIRST PERIOD HIGHLIGHTS...BUT CONDITIONS WILL LIKELY APPROACH SCEC
CRITERIA TOMORROW NIGHT.

FIRE WX: WITH CONTINUED QUITE WARM TEMPS AND MUCH DRIER WEATHER
EXPECTED FOR SUNDAY...CONDITIONS WILL WARRANT A FIRE WEATHER WATCH
FOR ALL FL ZONES...AS OFFSHORE NORTHERLY FLOW SHOULD BE STRONG
ENOUGH TO SUPPRESS THE SEA BREEZE FOR MUCH OF THE DAY.

EXTENDED: A STRONG UPPER RIDGE SHOULD BUILD IN FROM EARLY TO MID
WEEK NEXT WEEK...CONTINUING THE GENERAL HOT AND DRY PATTERN OVER THE
REGION.
