AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MIAMI FL
937 AM EDT SAT SEP 2 2006

.UPDATE...THE MIAMI SOUNDING THIS MORNING SHOWS A VERY MOIST
ENVIRONMENT IN PLACE ACROSS THE AREA...WITH A PWAT OF 2.10 INCHES.
H5 TEMP IS -7.5C...AND STABILITY INDICES SUGGEST ANOTHER ACTIVE
AFTERNOON TAKING SHAPE WITH NUMEROUS THUNDERSTORMS EXPECTED TO
DEVELOP ACROSS THE AREA. THE LOCAL AREA REMAINS TO THE EAST OF A
BROAD TROUGH SET UP ACROSS THE GULF OF MEXICO...SO A SOUTHWEST
LOW/MID LEVEL FLOW CONTINUES. EXPECT STORMS TO AFFECT THE GULF
COAST AND INTERIOR BY EARLY AFTERNOON THEN MOVE TOWARDS THE EAST
COAST METROPOLITAN AREAS THROUGHOUT THE AFTERNOON INTO THE EVENING.

MAIN CONCERN IS FOR LOCALLY HEAVY RAINFALL DUE TO THE MOIST
AIRMASS IN PLACE. ALTHOUGH THE MIAMI SOUNDING WOULD SUGGEST WINDS
GENERALLY UNDER 30 MPH IN STORMS...SURROUNDING SOUNDINGS TAKEN
FROM KEY AND TBW SHOW A LITTLE MORE DRIER AIR IN THE LOW/MID
LEVELS...AND THIS SHOULD ADVECT INTO MAINLAND SOUTH FL THIS
AFTERNOON AND POSSIBLY ALLOW A FEW OF THE STORMS TO CONTAIN GUSTY
WINDS AS INHERITED HAZARDOUS WEATHER OUTLOOK MENTIONED...SO WE
OPTED TO KEEP THIS MENTION IN THE MORNING UPDATE. INHERITED HIGH
POPS LOOK GOOD...SO NO SIGNIFICANT CHANGES WILL BE MADE TO THE
FCST THIS MORNING. /GREGORIA

.PREV DISCUSSION...
DISCUSSION...SURFACE HIGH PRESSURE CURRENTLY OVER EXTREME SOUTH
FLORIDA WILL GRADUALLY MOVE NORTH TO THE LAKE OKEECHOBEE REGION
LATER SUNDAY AND THEN CONTINUE MOVING NORTH TO CENTRAL FLORIDA
LATER MONDAY. THEN AS A STRONG SHORT WAVE MOVES INTO THE GULF OF
MEXICO TUESDAY NIGHT INTO WEDNESDAY, THE SURFACE RIDGE MOVES BACK
INTO SOUTH FLORIDA FOR THE TIME PERIOD WEDNESDAY THROUGH SATURDAY.
STEERING FLOW REMAINS LIGHT BUT FROM THE SOUTHWEST TODAY BECOMING
SOUTHEAST MONDAY AND THEN BACK TO THE SOUTHWEST WEDNESDAY. BOTH
TODAY AND SUNDAY ARE GOING TO BE FAIRLY WET WITH PWATS ABOVE
2.25. A MID/UPPER LOW AROUND 25N 72W WILL MOVE TO JUST SOUTHEAST
OF THE CWA BY SUNDAY WHICH WILL AID IN THE AMOUNT OF PRECIP WITH
UPPER LEVEL DIVERGENCE. THEN BY MONDAY, THE PWATS DROP TO AOB 2
INCHES BY MONDAY, WHICH MEANS THE POPS WILL BE CLOSER TO NORMAL
THROUGH THE WEEK. HAVE WENT ALONG WITH THE MAVMOS FOR NOW WITH 80
PERCENT POPS OVER THE CENTRAL AND EAST MAINLAND, 70 PERCENT SAME
AREAS SUNDAY AND THEN LOWERING TO 60 PERCENT MONDAY AND THEN 40-50
PERCENT TUESDAY ON. THE MAIN CHANGE FROM THE PREVIOUS PACKAGE WILL
BE TO INCREASE THE POPS TODAY.

AVIATION...EXPECT VFR CONDITIONS OVERNIGHT AT ALL TERMINALS...
HOWEVER WITH DEEP SWLY FLOW REMAINING IN PLACE THERE SHOULD BE AT
LEAST A FEW SHOWERS DEVELOPING ACROSS THE GULF OF MEXICO DURING
THE OVERNIGHT HOURS WHICH MAY APPROACH KAPF VERY LATE TONIGHT.
STORMS SHOULD FIRE JUST INLAND ALONG WEST COAST SEA BREEZE BY
MIDDAY SATURDAY AND MOVE EAST TOWARDS THE EAST COAST TERMINALS IN
THE EARLY AFTERNOON. MODELS HINT AT EAST COAST SEA BREEZE
DEVELOPING EARLY TOMORROW AFTERNOON AS WELL AND THIS MAY FIRE
ADDITIONAL STORMS THAT IMPACT THE EAST COAST TERMINALS AS WELL.

MARINE...WINDS WILL BE PRIMARILY SOUTH TO SOUTHEAST 10 KNOTS OR
LESS BECOMING MORE SOUTHEAST BY MONDAY AS THE RIDGE MOVES NORTH.
SEAS WILL BE 2 FEET OR LESS OUTSIDE OF CONVECTION.

FIRE WEATHER...NO CONCERNS HERE.
