AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MIAMI FL
327 AM EST THU FEB 18 2010

.DISCUSSION...WEAK COLD FRONT OVER THE SOUTHERN PENINSULA VERY
HARD TO FIND ATTM. BUT UNDER NORTHWEST FLOW, THE DRY AIR THAT WILL
BE MOVING IN ABOVE THE SURFACE WILL MIX DOWN AND THEN THE EFFECTS
OF THE FRONT WILL BE FELT WITH DRIER AIR. HIGH PRESSURE RIDGING
OVER SOUTHEAST TEXAS WILL MOVE VERY SLOWLY EASTWARD AND WILL REACH
FLORIDA THIS WEEKEND AND THEN MOVE EAST INTO THE ATLANTIC MONDAY
AS ANOTHER FRONT MOVES INTO NORTH FLORIDA EARLY MONDAY AND WILL
MOVE THROUGH SOUTH FLORIDA TUESDAY MORNING. THE LOW AND THE
CONVECTIVE FEEDBACK THAT WAS SHOWN ON THE EARLY MODEL RUNS IS NOW
GONE AND IT APPEARS WE WILL HAVE A SIMPLE COLD FRONTAL PASSAGE.
AFTER FAIRLY COOL TEMPS THROUGH SATURDAY MORNING, THE WARM UP
REALLY BEGINS. TEMPS WILL REACH NEAR NORMAL VALUES BY SUNDAY AND
MONDAY. MAVMOS SHOWS 50 PERCENT POPS ON MONDAY AND 40 PERCENT POPS
MONDAY NIGHT, BUT SINCE IT'S STILL TOO FAR OUT, LEFT IN THE 30
PERCENT. BY MID WEEK BEHIND THE NEXT FRONT, EXPECT COOLER WEATHER
AGAIN BUT NOT AS COOL AS WE HAVE BEEN EXPERIENCING. THE MIN TEMPS
WILL BE IN THE 40S NORTHWEST TO THE 50S SOUTHEAST AND HIGHS WILL
BE MAINLY THE LOWER TO MID 70S, ONLY SLIGHTLY BELOW NORMAL.

&&

.MARINE...NORTHWEST WINDS AT 15 OR 20 KNOTS WILL DECREASE TODAY
AND EVENTUALLY BECOME NORTH TO NORTHEAST AT LIGHT SPEEDS BY
SATURDAY AND WILL SHIFT TO THE EAST BY SUNDAY AND TO THE SOUTH BY
MONDAY. OUTSIDE OF SCA SEAS IN THE GULF STREAM EARLY TODAY, SEAS
WILL BE 4 MAYBE 5 FEET OR LESS THROUGH THE FORECAST PERIOD.

&&

.FIRE WEATHER...BEHIND THE PASSAGE OF THE FRONT WILL BRING IN LOW
LEVEL DRIER AIR WHICH WILL MIX DOWN TO THE SURFACE MAINLY OVER THE
NORTHERN AND EASTERN SECTIONS. THESE ARE THE AREAS THAT WILL SEE
DURATIONS OF 4 OR MORE HOURS. THEREFORE A RED FLAG WARNING WILL BE
ISSUED FOR THESE AREAS. ON FRIDAY AFTERNOON, THE MINIMUM RH'S WILL
GET DOWN TO JUST BELOW 35 PERCENT OVER THE WESTERN SECTIONS BUT
DOESN'T LOOK LIKE THE DURATION OF 4 HOURS WILL BE MET. AFTER FRIDAY,
DON'T SEE ANY PROBLEMS UNTIL POSSIBLY BEHIND THE NEXT FRONT NEXT
WEEK.
