350 AM EST MON DEC 15 2008

.SHORT TERM...TODAY THROUGH TUESDAY...SFC RIDGE OVER THE WRN
ATLANTIC WILL MOVE SLOWLY NE AS IT ELONGATES FROM NE TO SW. THIS
WILL RESULT IN A MAINLY EAST LOW LVL FLOW THROUGH THIS PERIOD.
THIS FLOW, IN TURN, WILL CONTINUE TO ADVECT L/M LVL PATCHES OF
CLOUDS/MOISTURE FROM THE ATLANTIC WEST OVER THE LOCAL AREA.
ALTHOUGH THERE IS NOT MUCH PRECIP ASSOCIATED WITH THESE
PATCHES...ENHANCED LOW LVL CONVERGENCE OVER ERN PORTIONS OF THE
LOCAL AREA MAY HELP TO SQUEEZE A SHOWER OR TWO FROM THESE CLOUDS.
WL KEEP JUST A SLIGHT CHANCE OF RAIN...MAINLY ERN HALF...THROUGH
THIS PERIOD TO ACCOUNT FOR THIS.

&&

.LONG TERM...WEDNESDAY THROUGH SUNDAY...A LARGE DEEP LAYER RIDGE
WILL BUILD FROM ERN PACIFIC NEWD THROUGH GULF OF MEX/FLORIDA
PENINSULA AND OVER THE NWRN ATLANTIC. THIS RIDGE WILL NOT ONLY
FORCE THE POLAR JET NORTHWARD AND KEEP ANY OTHER WEATHER FEATURE
FROM APPROACHING THE LOCAL AREA FROM THE NORTHWEST, BUT WILL ALSO
RESULT IN MOD/STG SUBSIDENCE. SO, THE RESULT WILL BE DRY AND WARM
CONDITIONS THROUGH THIS PERIOD. GFS HINTS AT A POSSIBLE BREAK ON
THESE CONDITIONS BY DAY 7 (SUNDAY) AS THE POLAR JET DIVES SOUTH
ACROSS THE CENTRAL PORTION OF THE COUNTRY SHOVELING THE RIDGE OUT
OF THE AREA. THE ECMWF HOWEVER, KEEPS THE RIDGE (ALTHOUGH WEAKER)
ACROSS THE AREA THROUGH THE ENTIRE EXTENDED PERIOD. GIVEN THE FACT
THAT THIS IS SO FAR IN THE FUTURE, WL NOT BE CONSIDERED IN THIS
FORECAST PACKAGE, AND SO THE CHANCES FOR RAIN, OR ANY SIGNIFICANT
CHANGE THROUGH THIS PERIOD, WILL BE LOW, IF ANY AT ALL.

.MARINE...EAST WINDS SHOULD CONTINUE TO DECREASE TODAY AS THE SFC
RIDGE MOVES NORTHEAST AND SO IMPROVING MARINE CONDITIONS ARE
EXPECTED. HOWEVER, WL LET CURRENT SCA TO CONTINUE FOR THE ATLC
WATERS TO CONTINUE FOR THE EARLY MORNING HOURS LATEST OBS STILL SHOW
FREQUENT GUSTS TO WELL ABOVE 20 KNOTS. BOTH WINDS AND SEAS SHOULD REMAIN
BELOW SCA CRITERIA THROUGH THE REMAINDER OF THE FORECAST PERIOD. A
SMALL NE SWELL IS EXPECTED TO AFFECT THE ATLC WATERS OFF PALM BEACH
FROM MID-WEEK ON.

.FIRE WEATHER...NO PROBLEMS EXPECTED AT THIS TIME.
