AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BURLINGTON VT
132 AM EDT THU MAR 20 2008

.SYNOPSIS...
WINTER WILL BE HANGING IN TOUGH ACROSS THE REGION. A STORM SYSTEM
WILL TREK ACROSS THE REGION OVERNIGHT...BRINGING RAIN TO MOST
LOCATIONS. AS THE LOW PASSES BY...COLDER AIR WILL TURN THE
PRECIPITATION TO SNOW. STRONG NORTHWEST WINDS...GUSTING AT TIMES
OVER 40 MPH...WILL DEVELOP AND HELP FOCUS THE SNOW ACROSS THE
HIGHER TERRAIN OF NORTHERN NEW YORK AND VERMONT. BY THE TIME THIS
SNOW TAPERS OFF ON FRIDAY...SOME AREAS WILL RECEIVE WELL OVER 6
INCHES OF SNOW. THE WEEKEND LOOKS TO BE DRY AND COOL.

&&

.NEAR TERM /UNTIL 6 AM THIS MORNING/...
AS OF 1003 PM EDT WEDNESDAY...THE APPROACHING LOW PRESSURE SYSTEM
IS CURRENTLY LOCATED IN CENTRAL PENNSYLVANIA...AND EXPECT THIS
LOW TO CONTINUE TO LIFT NORTH INTO NEW YORK STATE BEFORE BEING
PUSHED EAST ACROSS CENTRAL NEW ENGLAND. THE LARGE AREA OF
PRECIPITATION ASSOCIATED WITH THIS SYSTEM HAS ALREADY BEGUN TO
OVERSPREAD THE FORECAST AREA. WITH TEMPERATURES GENERALLY IN THE
LOWER TO MID 30S...EXPECT MOST AREAS TO INITIALLY SEE RAIN MIXED
WITH SLEET AND SNOW...THEN TRANSITION OVER TO ALL SNOW AFTER
MIDNIGHT. THERE MAY ALSO BE SOME POCKETS OF FREEZING
RAIN...ESPECIALLY EAST OF THE GREENS AND IN THE NORTHEAST KINGDOM
WHERE THE COLDER VALLEYS ARE ALREADY BELOW FREEZING. SNOW
ACCUMULATIONS SHOULD BE AN INCH OR LESS. UPDATED THE FORECAST TO
REFRESH THE WORDING MORE TO THIS LINE OF THINKING...AND ALSO TO
TWEAK MIN TEMPS JUST A BIT. THE REST OF THE FORECAST LOOKS
GOOD...SO NO OTHER CHANGES NEEDED.

&&

.SHORT TERM /6 AM THIS MORNING THROUGH 6 PM FRIDAY/...
AS OF 401 PM EDT WEDNESDAY...TWO PRIMARY THINGS WE WILL BE DEALING
WITH WILL BE SNOW AND WIND. FIRST THE WIND. AS THE LOW DEPARTS IT
WILL CONTINUE TO STRENGTHEN AND SLOW DOWN AS UPPER LOW CUTS OFF
OVER NEW ENGLAND. THIS WILL RESULT IN A STRONG NORTHWEST WIND
DEVELOPING. BUFKIT ANALYSIS OF MODEL SOUNDINGS SHOW WINDS OF 40 TO
50KT DEVELOPING LATE THURSDAY INTO FRIDAY AS LOW AS 925MB...JUST A
COUPLE THOUSAND FEET UP. WITH LAPSE RATES GENERALLY DRY ADIABATIC
DUE TO THE CAA...WE SHOULD EASILY MIX INTO SOME OF THAT WIND EVEN
DOWN IN LOWER VALLEYS. NEEDLESS TO SAY UP AT HIGHER ELEVATIONS IT
WILL BE EVEN WINDIER. HAVE DECIDED TO HOLD OFF ON ANY WIND
ADVISORIES AS YET...BUT WILL HIT IT IN THE HWO.

THESE NORTHWEST WINDS WILL ALSO RESULT IN EXCELLENT OROGRAPHIC
ENHANCEMENT AS IT ENCOUNTERS THE DACKS AND GREEN MOUNTAINS. THIS
WILL HELP SQUEEZE OUT THE MOISTURE THAT WILL REMAIN IN PLACE BELOW
10KFT. WITH TEMPERATURES FALLING WE WILL SEE GOOD COMBINATION OF
VERTICAL MOTION...MOISTURE AND OMEGA TO RESULT IN EXCELLENT SNOW
GROWTH POTENTIAL. TOPPING IT ALL OFF...THE STRONG NORTHWEST FLOW
WILL REMAIN PRETTY MUCH IN PLACE FOR A GOOD 24 HOURS OR SO.

AS A RESULT...WE ARE LOOKING AT A SIGNIFICANT UPSLOPE SNOW EVENT
ACROSS NORTHERN NEW YORK AND VERMONT...ESPECIALLY THE WEST FACING
SLOPES OF THE MOUNTAINS. HIGHER TERRAIN WILL SEE ABOUT 1 FOOT OF
SNOW...IF NOT MORE. HAVE THUS RAISED A NUMBER OF WINTER STORM
WARNINGS AND ADVISORIES FOR PORTIONS OF THE REGION. DOWN ACROSS
SOUTHERN VERMONT...ALTHOUGH THERE WILL BE SOME SNOW
SHOWERS...THERE WILL BE NOT NEARLY THE AMOUNT OF ACCUMULATION.

THINGS WILL BEGIN TO WIND DOWN ACROSS THE DACKS THURSDAY
NIGHT...BUT LINGERING MOISTURE WILL CONTINUE TO AFFECT NORTHERN
VERMONT THRU THE NIGHT.

&&

.LONG TERM /FRIDAY NIGHT THROUGH WEDNESDAY/...
AS OF 330 PM EDT WEDNESDAY...LINGERING UPSLOPE SNOW SHOWERS
SHOULD FINALLY CEASE BY LATE FRIDAY AFTERNOON. LOOKING PRETTY COLD
AND DRY THROUGH THE WEEKEND...WITH JUST A CHANCE OF SNOW SHOWERS
ACROSS THE HIGHER ELEVATIONS OF NORTHERN VERMONT AND THE
ADIRONDACKS IN FAVORABLE UPSLOPE REGIONS OF THE FORECAST AREA.
ALTHOUGH...NO SIGNIFICANT SNOWFALL ACCUMULATIONS ARE EXPECTED OVER
THE WEEKEND...JUST SHOWERS. NEXT ACTIVE WEATHER PERIOD MAY BEGIN
MONDAY AFTERNOON AS POTENTIAL CYCLOGENESIS COMES TOGETHER OFF THE
CAROLINAS COAST. MODEL RUNS ARE PRETTY INCONSISTENT RIGHT NOW WITH
ONE BRINGING IT CLOSE TO THE COAST AND THE NEXT PRETTY FAR OUTSIDE
THE BENCH MARK. HAVE INCLUDED CHANCE FOR SNOW SHOWERS RIGHT
NOW...AS THERE IS TOO MUCH INCONSISTENCY TO HAVE ANY CONFIDENCE
BEYOND A 30 POP. THE ECMWF IS ALSO NOW KEEPING THE STORM OFFSHORE.
WILL CONTINUE TO MONITOR POTENTIAL.

THROUGH 06Z FRIDAY...DIFFICULT AND CHALLENGING NEXT 6 TO 18 HR AVIATION
