AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GRAY ME
916 PM EST THU DEC 23 2004

.UPDATE...
WILL BE ISSUING UPDATE TO FRESHEN 1ST PERIOD WORDING BUT NOT LOOKING
AT ANY MAJOR CHANGES TO CURRENT FORECAST. COLD FRONT ON SCHEDULE
AND IS CURRENTLY MOVING THROUGH THE CONN VALLEY. SHARP CUTOFF TO
PRECIP WITH THIS BOUNDARY SO MAY ADJUST WORDING IN SOME ZONES TO
FIT LATEST RADAR TRENDS.

WINDS DROP OFF SIGNIFICANTLY BEHIND THE FRONT SO WILL LET WIND
WARNINGS AND ADVISORIES EXPIRE AT DESIGNATED TIMES.

CONTINUING STORM WARNING FOR THE COASTAL WATERS FORECAST WITH NO
CHANGES TO CURRENT FORECAST.

.PREVIOUS DISCUSSION...
.SHORT TERM (TONIGHT AND FRIDAY)...
MOST OF THE WEATHER IN THE NEXT FEW DAYS WILL OCCUR TONIGHT. THE
SURFACE LOW IS DEEPENING OVER LAKE ERIE...AND ALL MODELS ARE IN
DECENT AGREEMENT WITH THE TRACK. AHEAD OF THIS...WINDS ARE STARTING
TO INCREASE IN THE SOUTH TO SOUTHEAST GRADIENT. RAIN IS STARTING TO
GET INTO THE WESTERN ZONES...AHEAD OF THE MAIN SYSTEM.

THE PROGRESSION OF EVENTS SEEMS STRAIGHTFORWARD. WINDS WILL
INCREASE AHEAD OF THE APPROACHING FRONT IN THE GRADIENT. THE LIFT
AHEAD OF IT IS IMPRESSIVE...AND A PERIOD OF HEAVY RAIN IN POSSIBLE
THIS EVENING. THE MAINE FORECAST PROBLEM IS...OF COURSE...THE WIND.

PROFILERS TO THE WEST...AS WELL AS GUSTS HEAD OF THE FRONT IN
WESTERN NEW YORK...SUGGEST THAT THE MODEL SOUNDINGS ARE IN THE
BALLPARK WITH RESPECT TO STRENGTH OF THE LOW LEVEL JET. AS IS
USUALLY THE CASE IN A SOUTH TO SOUTHEAST FLOW...THE QUESTION
BECOMES ONE OF HOW MUCH MOMENTUM TO MIX DOWN. STABILITY DECREASES
AHEAD OF THE FRONT...AND THE ATMOSPHERE BECOME NEUTRAL JUST AHEAD OF
THE FRONT.

BASED ON THIS...WILL RAISE A HIGH WIND WARNING FOR THE MID COAST OF
MAINE...AND A WIND ADVISORY ELSEWHERE. IT IS POSSIBLE THAT MOST
LOCATIONS AWAY FROM THE COAST MAY NOT SEE ADVISORY WINDS...BUT MOST
PLACES WITH ELEVATION SHOULD...AS WINDS MIX DOWN IN THESE AREAS.

WILL END THE PRECIPITATION QUICKLY WITH THE FRONT...BUT THERE MAY
BE SOME SNOW ON THE TAIL END OF THE PRECIPITATION AS THE COLD AIR
COMES RUSHING IN BEHIND THE MAIN SYSTEM. TEMPERATURES WILL RISE IN
MOST PLACES THROUGH THE EVENING...THEN FALL QUICKLY BEHIND THE
FRONT.

FOR FRIDAY...THE WINDS DROP OFF QUICKLY AS THE ATMOSPHERE REMAINS
PROGRESSIVE. WHILE MOS NUMBERS INDICATE FALLING TEMPERATURES...NOT
SURE THIS WILL HAPPEN OUTSIDE OF THE MOUNTAINS...AS THE COLD AIR
ADVECTION IS SIMPLY NOT THAT IMPRESSIVE. WILL ALLOW TEMPERATURES TO
REBOUND SLIGHTLY IN THE AFTERNOON. AFTER MORNING SUNSHINE...COULD
SEE SOME HIGH CLOUDS IN THE FAST FLOW IN THE AFTERNOON.
&&

.LONG TERM (FRIDAY NIGHT THROUGH THURSDAY)...
ZONAL FLOW SETS UP THROUGH MOST OF THE EXTENDED PERIOD...WITH
NO MAJOR EVENTS FORESEEN. GENERALLY FOLLOW THE UKMET/ETA/GEM SOLUTION
IN THE MID-RANGE...WHICH ESSENTIALLY DIG A 500 MB TROF FURTHER
SOUTH THAN THE GFS ON SUN/MON...RESULTING IN A COLDER SOLUTION.
CONSIDERED A CHANCE OF A SNOW SHOWER SUNDAY NIGHT...HOWEVER GIVEN THE
DIFFICULTY TIMING SHORTWAVES THIS FAR OUT WILL CARRY SLIGHT CHANCE AN
GIVE ONE MORE MODEL RUN.

ALL MODELS TAKE FRIDAY NIGHTS SYSTEM OUT TO SEA...SO WILL NOT CARRY
POPS HERE. TRICKY SITUATION SETS UP SATURDAY NIGHT AS THE ETA SHOWS
A WEAK ONSHORE FLOW DEVELOPING. DURING THIS TIME...THE ATMOSPHERE IS
UNSTABLE IN THE LOW LAYERS...SO IT WILL NOT TAKE MUCH FLOW TO
GENERATE OCEAN EFFECT SNOWS. WILL CARRY CHANCE POPS HERE FOR NOW...AS
THIS IS A SUBTLE FEATURE.

BEYOND...USE GFS/GEM/EUROPEAN/UKMET CONSENSUS...WHICH IS GENERALLY
COLDER THAN THE GFS...AND IS SLOWER ON THE TIMING OF A SYSTEM ON
THURSDAY. GO BELOW MEX MOS FOR SUN-TUE...ESPECIALLY ON LOWS WHERE
THE MOUNTAIN VALLEYS HAVE A TENDENCY TO RADIATE WELL.
&&

.MARINE...
IN THE SHORT TERM...WINDS ARE JUST GETTING TO GALE AT MISM1. AS THE
GRADIENT INCREASES...WOULD EXPECT ALL WATERS TO BE GALE SOON. BASED
ON PROFILERS TO THE WEST...WOULD EXPECT THAT MISM1 WILL SEE STORM
GUSTS IN THE SOUTHERLY FLOW...WITH GALES ELSEWHERE.  WITH THE
PASSAGE OF THE FRONT...EXPECT AN ABPRUT CHANGE IN DIRECTION WITH
WINDS DROPPING TO GALE OR BELOW. AFTER THIS...EXPECT WINDS TO DROP
BELOW SMALL CRAFT LEVELS FOR FRIDAY...BUT SEAS WILL SLOSH ON THEIR
WAY DOWN FRIDAY.

LOOKING AHEAD...APPEARS TO BE QUIET ON THE WATERS. WAVE WATCH
INDICATES SEAS TO BE MARGINAL SCA...AS LEFTOVER SWELL KEEPS WAVES
AROUND 4 FT THROUGH TUE.

.AVIATION...
TERMINALS ARE IMPROVING AS THE WARM FRONT IS MIXING DOWN FROM ABOVE.
THIS SHOULD BE TEMPORARY...AS CEILINGS AND VISIBILITIES COME DOWN TO
IFR/MVFR RESPECTIVELY. INCLUDED LOW LEVEL WIND SHEAR AS THE ETL
PROFILER AT CONCORD...AS WELL AS VWP WINDS...SHOW 50 TO 60 KNOTS
UNDER 2000 FEET.

WOULD EXPECT CEILINGS AND VISIBILITIES TO IMPROVE TO VFR WITH THE
PASSAGE OF THE FRONT...BETWEEN 04Z AND 08Z FROM WEST TO EAST.
