Severe Thunderstorm Warning 78, NWS Miami, FL

SOUTH FLORIDA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MIAMI FL
200 PM EDT THU AUG 12 2004

.DISCUSSION...STILL WAITING FOR CHARLEY TO MAKE ITS IMPACT FELT
WHICH WILL GOVERN THE WEATHER THROUGH FRIDAY.  THE WAY IT LOOKS NOW
THE RAIN WILL START OVER THE WESTERN ZONES LATE TONIGHT AND OVER THE
EASTERN ZONES TOMORROW AFTERNOON.  SINCE THERE IS A LARGE AREA OF
DRIER AIR NORTH AND EAST OF THE STORM THE EXTREME EASTERN PORTION OF
THE ZONES WILL BE A PLACE WHERE THE RAIN CHANCE CAN BE LOWER THAN
WHAT WILL BE MENTIONED IN THE TEXT.  WE WILL STILL FEEL THE EFFECTS
OF CHARLEY ON SATURDAY IN THE FORM OF SOME FEEDER BAND THROUGH OUR
ZONES. SO WE ARE STILL LIKELY TO HAVE A HIGH PROBABILITY OF RAIN
ALTHOUGH NOT COMPLETELY CONFIDENT OF THE LOCATION.  AT PRESENT HAVE
PUT IT OVER THE NORTHERN ZONES.  BEGINNING NEXT WEEK WE SHOULD HAVE
THE SURFACE RIDGE BACK OVER THE AREA.  MORE IMPORTANT THE UPPER
RIDGE THAT HAS BEEN FORCING CHARLEY WEST SHOULD BE WELL IN PLACE
OVER OUR AREA AND WE SHOULD BE JUST A LITTLE BELOW CLIMATE ON THE
PROBABILITIES. AM DISREGARDING ANY POTENTIAL TROPICAL FEATURES
DURING THE EXTENDED PERIOD.
&&

.MARINE...BETWEEN BONNIE AND CHARLEY WE ARE UP TO SMALL CRAFT ON THE
ATLANTIC SIDE. WILL STAY IN THIS SITUATION UNTIL LATE FRIDAY NIGHT
AND THEN SEE A DECREASE TO EXERCISE CAUTION SATURDAY. BY SATURDAY
NIGHT AND THEN THROUGH THE THE REST OF THE FORECAST WE SHOULD BE 15
KNOTS OR LESS.
&&

.FIRE WEATHER...EVEN THOUGH WINDS AND DSI WILL REMAIN HIGH HUMIDITY
VALUES WILL REMAIN ABOVE THE 35 PERCENT THRESHOLD SO NO NEED FOR ANY
ADVISORIES.
