AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE MIAMI FL
1015 AM EDT THU AUG 16 2006

.UPDATE...12Z MIA SOUNDING CAME IN WITH A FAIRLY DEEP (10K FEET) AND
STEADY SOUTHEAST FLOW. TAKING THIS INTO ACCOUNT...WILL EXPECT
DEVELOPING SEA BREEZE ALONG SOUTHEAST TO PENETRATE FURTHER INLAND AS
IT IS ENHANCED BY THE PREVAILING LOW LEVEL FLOW. THIS LOW LEVEL FLOW
WILL ALSO TEND TO INCREASE LOW LEVEL CONVERGENCE ACROSS SOUTHERN
PORTIONS OF LAKE OKEECHOBEE AND ACROSS WEST COAST. WEAK DIVERGENCE
AT UPPER LEVEL WILL HELP WITH ANY CONVECTION THAT DEVELOPS THIS
AFTERNOON. WITH THIS IN MIND...DECIDED TO GO ISOLATED POPS FOR
MIA/FLL AND SOUTHEAST/SOUTHERN PORTIONS OF THE PENINSULA WITH SCT
POPS ELSEWHERE. HIGHEST POPS ACROSS GLADES/HENDRY COUNTIES.

.PREVIOUS DISCUSSION...S FLA STILL UNDER 500 MB SHEAR ZONE AS AREA
BETWEEN HIGH PRES OVER SE U.S. AND OVER W CARIB EXTENDING NE ACROSS
BAHAMAS INTO THE W ATLC. THIS PATTERN PERSISTS TODAY AND FRI UNTIL
UPPER LOW OVER E GULF OF MEX MOVES INTO THE SW GULF OF MEX ALLOWING
THE SE U.S. UPPER RIDGE TO BUILD E INTO THE ATLC. THE 500 MB TROUGH
BEGINS TO REDEVELOP OVER THE E U.S. OVER THE WEEKEND AND INTO NEXT
WEEK WITH THE SE U.S. UPPER RIDGE MOVING W. AT THE SURFACE RIDGING
HAS BEGUN TO BUILD IN AND A SE WIND FLOW HAS DEVELOPED WHICH WILL
GRADUALLY DEEPEN THROUGH TODAY AND INTO FRI...PERSISTING THROUGH THE
FORECAST PERIOD.

FOR THE SHORT TERM...TODAY THROUGH FRI NIGHT...PRECIPITABLE WATER
FROM MFL 00Z RAOB ABOVE 2.00 IN+ AND CURRENT GPS INDICATES SAME.
MODELS DEPICT A GRADUAL DRYING. WITH DRIER AIR TO SE AND WITH A
DEEPENING EASTERLY WIND FLOW DEVELOPING...WILL FOLLOW MET GUIDANCE
TO SOME EXTENT AND RAISE POPS A BIT TODAY...BUT OH SO SLIGHTLY.
TODAY STEERING FLOW ALMOST NIL SO THUNDERSTORMS DEVELOPING ALONG E/W
SEA BREEZES WILL POSSIBLY DRIFT EARLY DUMPING LOCALLY HEAVY RAINS
AGAIN...MAINLY INTERIOR AND W BUT COASTAL AREA TO SEE ACTION AS WELL
BEFORE CONVECTIVE ACTIVITY MOVES NW TO LAKE OKEE AREA. LIMITED E
COAST ACTIVITY TONIGHT/THU NIGHT WITH A MORE DEFINITE INTERIOR AND W
PATTERN FRI.

.EXTENDED PERIOD...SAT THROUGH WED...FAIRLY DEEP EASTERLY FLOW TO
CONTINUE WITH A SLIGHTLY DRIER ATMOSPHERE THROUGH MON. A POSSIBLE
DEEP MOISTURE INCREASE MON INTO TUE AS A TROPICAL WAVE APPROACHES
WITH SOME DRYING WED.

&&
.AVIATION...THE COMBINATION OF TWO UPPER LEVEL LOWS...ONE CENTERED
OVER CUBA AND THE OTHER IN THE CENTRAL GULF OF MEXICO...HAS CREATED
FAVORABLE UPPER LEVEL CONDITIONS FOR ENHANCING CONVECTION. LIMITED
AREAS OF CONVECTION AND ISOLATED THUNDERSTORMS ARE OCCURRING OVER
THE EASTERN SECTIONS OF SOUTH FLORIDA AND IN THE VICINITY OF NAPLES
EARLY THIS MORNING WITH BRIEF PERIODS OF IFR CONDITIONS POSSIBLE.
WITH THE ENHANCED LOW LEVEL MOISTURE OVER THE REGION AND WITH THE
DAY TIME HEATING TODAY...THUNDERSTORMS WILL POTENTIALLY DEVELOP OVER
THE PENINSULA MID-MORNING...PRODUCING PERIODS OF IFR CONDITIONS IN
THE MORNING AND POTENTIALLY LATER IN THE AFTERNOON.

&&
.MARINE...E/SE WINDS MOSTLY 10 TO 15 KNOTS...SOMETIMES LESS THAN
THAT...WITH SEAS 4 FEET OR LESS ATLC WATERS AND 2 TO 3 FEET OR LESS
GULF WATERS.
