AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MIAMI FL
408 AM EDT FRI MAY 8 2009

.DISCUSSION...HIGH PRESSURE FROM 29N TO CENTRAL FLORIDA WILL SLIDE
SOUTH TO 28N TO SOUTH FLORIDA. ANYWAY, THE RIDGE IS FAIRLY WEAK
OVER FLORIDA WHICH MEANS THE SEABREEZES WILL BE ACTIVE TO PRODUCE
A SLIGHT CHANCE OF SHOWERS TODAY OVER THE NORTHWEST INTERIOR WHERE
THE SEABREEZES MEET. THE SAME SCENARIO WILL CONTINUE THROUGH EARLY
NEXT WEEK, EXCEPT A SLIGHT CHANCE FOR THUNDER STARTING SATURDAY
WITH MORE INSTABILITY AND HIGHER MEAN LAYER MOISTURE.

A COLD FRONT WILL COME OFF THE CAROLINA COAST MIDDAY MONDAY AND
ENTER NORTH FLORIDA LATER MONDAY. MID LEVEL HEIGHTS LOWER ENOUGH
THAT THIS FRONT WILL SLOWLY MOVE INTO SOUTH FLORIDA BY WEDNESDAY
AND STALL THURSDAY. PREVIOUS MODEL RUNS HAVE SHOWN THIS AND THERE
MAY BE THUNDER POSSIBLE IN SOME AREAS. THE HIGHEST POPS WILL ONLY
BE 30 PERCENT OVER THE INTERIOR BUT THAT DOESNT RULE OUT A SLIGHT
CHANCE OVER THE COASTAL SECTIONS. WITH THE FRONT IN THE AREA, SOME
CLOUDS AND RAINFALL WILL KEEP THE HIGH TEMPERATURES ONLY IN THE
MID TO UPPER 80S AND THE LOWS IN THE 60S INTERIOR AND WEST AND
NEAR 70 TO THE LOWER 70S EAST COAST MID TO LATE WEEK.

&&

.MARINE...MAINLY EAST TO SOUTHEAST WINDS OF LESS THAN 15 KT WILL
RESULT IN SEAS OF LESS THAN 4 FEET THROUGH THE PERIOD.

INCREASE LAST FEW DAYS AND NAM12 AND LOCAL WRF STILL SHOW MIN
