AREA FORECAST DISCUSSION

945 AM EST SAT MAR 26 2005

.DISCUSSION...

...LIGHTNING STORMS WILL REDEVELOP TODAY WITH THE POTENTIAL FOR HAIL
AND STRONG WINDS...INCLUDING ISOLATED TORNADOES...

WARM FRONT ACROSS OUR NORTHERN COUNTIES WILL LIFT NORTH OF THE AREA
THIS AFTERNOON. LOW CLOUDS AND FOG CURRENTLY OVER NORTH HALF IS
SLOWING THE RATE OF BOUNDARY LAYER DESTABILIZATION THERE. HOWEVER...
THESE LOW CLOUDS AND FOG WILL LIFT AND DISSIPATE NEXT FEW HOURS
PLACING ENTIRE FORECAST AREA IN A WARM UNSTABLE AIRMASS WITH TEMPS
RISING INTO THE LOWER-MID 80S AND DEWPOINTS NEAR 70. CAPE SOUNDING
SHOWS ATM NOT QUITE AS UNSTABLE AS YESTERDAY...DUE TO WEAK SHORT
WAVE RIDGING AT H5 WHICH HAS WARMED H5 TEMPS TO -11C AND LAPSE RATES
NOT QUITE AS STEEP.

BUT MAKE NO MISTAKE...ATMOSPHERE REMAINS UNSTABLE WITH LI -7.5 AND
SIGNIFICANT MOISTENING IN THE LOW LEVELS (PWATS 1.77). DRY AIR IN
THE MID LEVELS WILL AGAIN PRODUCE HAIL AND EXCESSIVE LIGHTNING. FLOW
ALOFT REMAINS SLIGHTLY NORTH OF DUE WEST WHICH IMPLIES SOME
PROPAGATION OF BOUNDARIES/CONVECTION SOUTHWARD INTO ORLANDO METRO.
THIS IS SHOWN BY EXPERIMENTAL ARPS MODEL THOUGH IT APPEARS A BIT TOO
FAST...BRINGING CONVECTION INTO ORLANDO BY 16Z. HIGHEST HELICITIES
WILL LIFT NORTH WITH THE WARM FRONT THIS AFTN BUT NORTHERN SECTIONS
(LAKE/VOLUSIA/SEMINOLE) ARE MOST AT RISK INITIALLY ONCE STORMS CAN
BECOME ROOTED IN THE BOUNDARY LAYER. WILL ALSO BE WATCHING CLOSELY
FOR DEVELOPMENT OF EAST COAST SEA BREEZE WHICH WILL LOCALLY ENHANCE
THE LOW LEVEL SHEAR AND CONTINUE THE ISOLATED TORNADO THREAT DOWN
THE COAST.

&&

.MARINE...CONCERN FOR BOATERS TODAY WILL BE STORMS MOVING OFFSHORE
CONTAINING FREQUENT TO EXCESSIVE LIGHTNING...HAIL AND STRONG WINDS
IN EXCESS OF 35 KNOTS.

.MLB WATCHES/WARNINGS/ADVISORIES...NONE.

THIS HAZARDOUS WEATHER OUTLOOK IS FOR EAST CENTRAL FLORIDA.

.DAY ONE...TODAY.

...THUNDERSTORMS LIKELY WITH SEVERE STORMS POSSIBLE TODAY...

...THUNDERSTORM IMPACT...
A SURFACE BOUNDARY EXTENDING FROM THE EASTERN GULF ACROSS THE
CENTRAL FLORIDA PENINSULA EARLY THIS MORNING WILL LIFT NORTH AS
A WARM FRONT TODAY. A MOIST AND UNSTABLE AIR MASS WILL EXIST
OVER EAST CENTRAL FLORIDA TO THE SOUTH OF THIS BOUNDARY AND
INSTABILITY WILL BE INCREASED AS TEMPERATURES QUICKLY WARM INTO
THE 80S. STORMS ARE EXPECTED TO INITIALLY DEVELOP OVER NORTHERN
SECTIONS MID TO LATE MORNING...THEN STORM COVERAGE AND INTENSITY
WILL INCREASE HEADING INTO THE AFTERNOON HOURS. THE STORMS WILL
BE CAPABLE OF BECOMING STRONG TO SEVERE...PRODUCING STRONG AND
DAMAGING WIND GUSTS...COIN SIZE HAIL...AND FREQUENT TO EXCESSIVE
LIGHTNING. STORMS WILL MOVE TO THE EAST NORTHEAST TOWARD THE
EAST COAST TODAY. THE POTENTIAL EXISTS FOR TORNADO DEVELOPMENT
IN A FEW STRONGER STORMS...ESPECIALLY THIS AFTERNOON AS A SEA
BREEZE DEVELOPS NEAR THE EAST COAST AND ACTS TO INCREASE LOW
LEVEL WIND SHEAR. PERSONS PLANNING OUTDOOR ACTIVITIES SHOULD KEEP
INFORMED OF THE WEATHER AND BE PREPARED TO MOVE INDOORS TO A
SAFE LOCATION BEFORE A STORM IS OVERHEAD.

...FLOOD IMPACT...
RECENT RAINFALL HAS LEFT MUCH OF THE GROUND OVER EAST CENTRAL
FLORIDA NEAR SATURATION. ADDITIONAL DOWNPOURS TODAY WILL RESULT
IN FLOODING OF LOW LYING AND POOR DRAINAGE AREAS. LOCATIONS THAT
RECEIVED HEAVY RAINS ON FRIDAY WILL BE ESPECIALLY SUSCEPTIBLE
TO FLOODING PROBLEMS...INCLUDING VOLUSIA...SEMINOLE AND NORTHERN
BREVARD COUNTIES WHERE RAINFALL TOTALS IN EXCESS OF 3 INCHES
OCCURRED IN SPOTS. ALSO...HEAVY DOWNPOURS WILL LEAD TO TO POOR
VISIBILITY...SLICK ROADS AND STANDING WATER ON ROADS...SO DRIVERS
ARE URGED TO USE EXTRA CARE.

...MARINE THUNDERSTORM GUST IMPACT...
STRONG STORMS WILL BE POSSIBLE OVER THE INTRACOASTAL AND ATLANTIC
COASTAL WATERS TODAY. STORMS WILL BE CAPABLE OF PRODUCING WIND
GUSTS OVER 34 KNOTS...FREQUENT CLOUD TO WATER LIGHTNING AND
ROUGH SEAS. BE READY TO REACH SAFE HARBOR BEFORE STORMS APPROACH.

...WATERSPOUT IMPACT...
STORMS MOVING ACROSS THE INTRACOASTAL WATERWAY MAY ENCOUNTER
INCREASED WIND SHEAR WHICH CAN PROMOTE THE RAPID DEVELOPMENT OF
WATERSPOUTS. MARINERS SHOULD KEEP ALERT FOR DEVELOPING SHOWERS
AND THUNDERSTORMS.

.DAYS TWO THROUGH SEVEN...SUNDAY THROUGH SATURDAY.

...SEVERE STORMS POSSIBLE...ESPECIALLY OVERNIGHT SUNDAY INTO MONDAY...

SCATTERED THUNDERSTORMS WILL BE POSSIBLE DURING THE DAYTIME SUNDAY.

THERE IS INCREASING CONCERN OF A SQUALL LINE DEVELOPING AND MOVING
THROUGH EAST CENTRAL FLORIDA DURING THE OVERNIGHT HOURS SUNDAY NIGHT
INTO MONDAY. THIS SQUALL LINE WILL BE CAPABLE OF PRODUCING DAMAGING
WIND GUSTS...LARGE HAIL...EXCESSIVE LIGHTNING AND A FEW TORNADOES.

PERSONS IN EAST CENTRAL FLORIDA SHOULD MONITOR THE WEATHER CLOSELY
OVER THE REMAINDER OF THE WEEKEND. TO STAY INFORMED OF APPROACHING
SEVERE STORMS DURING THE OVERNIGHT HOURS...MAKE SURE YOUR NOAA
WEATHER IS SET TO ALERT BEFORE RETIRING FOR THE EVENING.
