HAZARDOUS WEATHER OUTLOOK FOR SOUTH FLORIDA

916 AM EDT TUE APR 10 2007

...A FEW STRONG STORMS POSSIBLE THIS AFTERNOON...

THIS HAZARDOUS WEATHER OUTLOOK IS FOR SOUTH FLORIDA.

.DAY ONE...TODAY AND TONIGHT

THUNDERSTORMS: LOW PRESSURE OVER THE GULF OF MEXICO WILL MOVE ACROSS
CENTRAL FLORIDA THIS AFTERNOON AND EVENING. MOISTURE AND
INSTABILITY WILL INCREASE ACROSS MAINLAND SOUTH FLORIDA OUT AHEAD
OF THIS LOW, RESULTING IN A CHANCE OF THUNDERSTORMS ACROSS THE
AREA TODAY. THE GREATEST POTENTIAL FOR THUNDERSTORMS WILL BE
DURING THE AFTERNOON AND EARLY EVENING ACROSS PALM BEACH, BROWARD,
AND MIAMI-DADE COUNTIES. ALTHOUGH LOW LEVELS ARE ONLY MARGINALLY
UNSTABLE, VERY COLD AIR ALOFT, ALONG WITH A FAST MID LEVEL WIND
FLOW, COULD ALLOW A FEW STORMS TO BECOME STRONG OR EVEN MARGINALLY
SEVERE THIS AFTERNOON, ESPECIALLY IF CLOUDS THIN ENOUGH TO ALLOW
FOR SUFFICIENT HEATING. THE STRONGER STORMS WOULD HAVE THE
POTENTIAL OF PRODUCING GUSTY WINDS AND HAIL IN ADDITION TO
DANGEROUS LIGHTNING AND LOCALLY HEAVY DOWNPOURS.

WIND: THE STRONGEST STORMS WILL BE CAPABLE OF PRODUCING WIND
GUSTS OF 40 TO 50 MPH THIS AFTERNOON AND EARLY THIS EVENING.

HAIL: THE STRONGEST STORMS WILL BE CAPABLE OF PRODUCING HAIL UP
TO PENNY SIZE THIS AFTERNOON AND EARLY THIS EVENING, MAINLY ALONG
THE ATLANTIC COAST.

.DAYS TWO THROUGH SEVEN...WEDNESDAY THROUGH MONDAY

ADDITIONAL THUNDERSTORMS ARE POSSIBLE ACROSS THE AREA OVER THE
NEXT FEW DAYS AS WARM AND HUMID AIR WILL REMAIN IN PLACE.

.SPOTTER INFORMATION STATEMENT...

SPOTTERS ARE REQUESTED TO REPORT WINDS OVER 40 MPH AND ANY HAIL.
