SOUTH FLORIDA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MIAMI FL
210 PM EDT SUN AUG 1 2004

.DISCUSSION...SOUTHWEST FLOW WILL CONTINUE ACROSS SOUTH FLORIDA
THROUGH THE FORECAST PERIOD. LITTLE CHANGE TO MAKE IN THIS FORECAST
PACKAGE OTHER THAN ADD A DAY TO THE EXTENDED PERIOD. T.D. ONE WILL
SLOWLY TO THE NORTH AND THEN GET PICKED UP BY UPSTREAM TROUGH AND
MOVE ALONG THE CAROLINA COASTLINE. RESULTING PICTURE FOR US IS TO
KEEP THE SURFACE RIDGE OVER THE EXTREME SOUTHERN TIP OF THE
PENINSULA OR JUST SOUTH OF THE REGION KEEPING PERSISTENT SW FLOW
FROM THE SURFACE TO ALOFT. AS THE AFOREMENTIONED UPSTREAM TROUGH
CONTINUES SOUTHEAST, T.D. ONE WILL GET PICKED UP BY THIS TROUGH BY
MIDWEEK AND THE GFS SUGGESTS DRIER AIR WILL MOVE SOUTH OVER THE
REGION BY THURSDAY AND FRIDAY. HOWEVER, WITH SW FLOW CONTINUING
BEHIND THIS SYSTEM, WILL NOT LOWER POPS AT THIS TIME AND KEEP
CURRENT TREND GOING.
&&

WITH SEAS FOUR FEET OR LESS. HAVE BEEN THINKING OF REWORDING ZONES
