AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BURLINGTON VT
718 PM EST WED FEB 20 2013

.SYNOPSIS...
CLOUDY SKIES ALONG WITH SCATTERED TO NUMEROUS SNOW SHOWERS OR
FLURRIES WILL BE THE RULE ACROSS OUR REGION THROUGH THURSDAY AS
MOISTURE WRAPS AROUND A SLOW MOVING UPPER LEVEL LOW PRESSURE
SYSTEM ACROSS NEW ENGLAND. HIGH PRESSURE RETURNS BY LATER
THURSDAY NIGHT INTO FRIDAY WITH FAIR WEATHER AND SEASONABLE
TEMPERATURES. BY NEXT WEEKEND ANOTHER AREA OF LOW PRESSURE WILL
BRING A RENEWED THREAT OF SNOW TO THE REGION.

&&

.NEAR TERM /UNTIL 6 AM THURSDAY MORNING/...
AS OF 659 PM EST WEDNESDAY...SOME MINOR ADJUSTMENTS TO HOURLY
PARAMETERS FOR THIS EVENING BASED ON LATEST OBSERVATIONS AND NEAR
TERM GUIDANCE. MOIST CYCLONIC FLOW CONTINUES AROUND SLOW MOVING
UPPER LOW...WITH PRECIPITATION ENHANCED AS SERIES OF VORT LOBES
ROTATE AROUND THE CLOSED LOW. BULK OF PRECIPITATION IS OCCURRING
ALONG AND JUST EAST OF THE WESTERN SLOPES OF VERMONT WHERE
ADVISORIES ARE IN EFFECT. AT LEAST SEVERAL INCHES OF SNOW HAVE
ALREADY ACCUMULATED IN THIS REGION THIS AFTERNOON WITH MORE ON THE
WAY. ELSEWHERE ACROSS THE NORTH COUNTRY...SCATTERED TO NUMEROUS
SNOW SHOWERS...BUT SNOWFALL RATES AND COVERAGE LESS THAN OVER THE
WESTERN SLOPES.

PREVIOUS DISCUSSION...
FORECAST REMAINS ON TRACK FOR THIS EVENING/TONIGHT AS LARGE SCALE
UPPER GYRE CONTINUES TO PINWHEEL ACROSS NORTHERN NEW ENGLAND AND
SOUTH CENTRAL CANADA. AS THIS FEATURE CONTINUES TO TRUDGE SLOWLY
EAST TONIGHT AN INCREASINGLY MOIST...CYCLONIC FLOW WILL DEVELOP
ACROSS OUR REGION WITH A BROAD INCREASE IN SNOW SHOWER
ACTIVITY...ESPECIALLY NORTH. THAT SAID...SEVERAL AREAS HAVE
ALREADY SEEN A DECENT COVERAGE OF LIGHT SNOW/SNOW SHOWERS
TODAY...NAMELY ACROSS THE FAR NORTHERN GREEN MOUNTAINS FROM MT
MANSFIELD NORTHWARD...AND DOWN IN THE KILLINGTON/OKEMO AREAS WHERE
LOCAL DOWNSTREAM ENHANCEMENT OF LAKE ONTARIO LAKE EFFECT PLUME HAS
OCCURRED. MEAN FROUDE NUMBER VALUES REMAIN QUASI-STATIC NEAR
CRITICAL VALUES UNTIL AROUND MIDNIGHT OR SO...THUS BEST INITIAL
ACCUMULATIONS WILL CONTINUE JUST WEST OF THE NRN GREEN MTN SPINE
AND SLIGHTLY EAST WHERE SOME MODEST ACCUMULATIONS WILL BE LIKELY.
ELSEWHERE...MAINLY VERY LIGHT SNOW/FLURRIES WITH ONLY MINOR
ACCUMULATIONS AT BEST GIVEN MEAN FLOW REMAINS WEST TO WEST-
NORTHWESTERLY AND SHADOWING EFFECTS DOMINATE. BY LATER TONIGHT
FLOW TRENDS SUB-CRITICAL AS LOW LEVEL FLOW BACKS TO NORTHWESTERLY
WITH APROACH OF ROBUST H5 TROUGH AXIS AND ACCOMPANYING SHORTWAVE.
THUS AREAL COVERAGE OF SNOWS/SNOW SHOWERS SHOULD TEND TO INCREASE
FURTHER AND BACK WESTWARD OUT INTO THE VT SIDE OF THE NORTHERN
CHAMPLAIN VALLEY TOWARD MORNING. ELSEWHERE...STILL A DECENT
COVERAGE OF LIGHT SHSN/FLURRIES...BUT INTENSITY AND ACCUMULATIONS
SLIGHTLY LESS. THUS ALL CURRENT ADVISORIES WILL REMAIN IN PLACE.
ONCE AGAIN...I DID OPT TO TREND QUITE A BIT MILDER THAN AVAILABLE
GUIDANCE GIVEN CLOUDS AND AT LEAST SOME BOUNDARY LAYER MIXING.
COMPLETELY THREW OUT THE NAM SOLUTION AS ONCE AGAIN IT APPEARS
MUCH TOO COLD (I.E. KBTV LOW OF +7F)

&&

.SHORT TERM /6 AM THURSDAY MORNING THROUGH FRIDAY NIGHT/...
AS OF 247 PM EST WEDNESDAY...AS WE PROGRESS INTO THURSDAY THE
DECENT COVERAGE OF SNOW SHOWERS/SNOW CONTINUES IN THE ADVISORY
AREA...BUT ALSO TENDS TO MAXIMIZE IN AREAL COVERAGE ACROSS THE
ADIRONDACKS INTO THE CHAMPLAIN VALLEY OF VERMONT WITH PASSAGE OF
AFOREMENTIONED UPPER SHORTWAVE TROUGH AXIS. INDEED MODEL/SOUNDING
PROFILES SHOW A MORE NORTH TO NORTHWESTERLY AND VEERED PROFILE
THROUGH 850 MB AS FLOW CONTINUES SUB-CRITICAL...SUPPORTING THE
IDEA OF ACTIVITY BACKING WESTWARD. BY LATER IN THE DAY AREAL
COVERAGE BEGINS TO SLOWLY DIMINISH AS BEST DYNAMICAL FORCING
SLIDES SOUTH AND EAST AND COLMNAR MOISTURE PROFILES BEGIN TO
SLOWLY THIN. BY DAYS END TOTAL ACCUMULATIONS IN THE ADVISORY AREA
LIKELY TO END UP IN THE 4-8 INCH RANGE WITH LOCAL POINT TOTALS
PERHAPS A TAD HIGHER. ELSEWHERE ACROSS OUR CENTRAL/NORTHERN
COUNTIES AND DOWN ALONG THE SPINE OF THE SOUTHERN GREENS SNOW
TOTALS TO RANGE BETWEEN 1 AND 4 INCHES. EVEN LESS IN THE FAR
SOUTHERN CHAMPLAIN VALLEY AND OUR LOWER CT RIVER VALLEY AREAS FROM
NEWBURY/WHITE RIVER SOUTH. USED A MODEL BLEND ON HIGH TEMPERATURES
OFFERING READINGS MAINLY IN THE 20S WHICH APPEARS REASONABLE GIVEN
LACK OF STRONG LOW LEVEL COLD THERMAL ADVECTION.

BY THURSDAY NIGHT ANY LINGERING EVENING SNOW SHOWERS/FLURRIES TO
COME TO AN END AS FAIRLY AMPLIFIED THOUGH NARROW SHORTWAVE RIDGE
AXIS BUILDS INTO THE REGION. THUS EXPECT SKIES TO START
CLOUDY...THOUGH GRADUALLY THIN TO PTLY CLOUDY/MOSTLY CLEAR BY FRIDAY
MORNING AS LOWS BOTTOM OUT IN THE UPPER SINGLE DIGITS INTO THE TEENS.

FRIDAY WILL BE THE BEST DAY IN THE SHORT TERM PORTIONS OF THE
FORECAST AS SFC TO H5 RIDGING BRIDGES ATOP AND EAST OF THE REGION.
AMPLE SUNSHINE AND MEAN 18Z 925 MB TEMPS IN THE -2C TO -5C RANGE
SHOULD ALLOW SFC TEMPERATURES TO CLIMB NICELY INTO THE 30S FOR MOST
AREAS UNDER LIGHT WINDS.

BY FRIDAY NIGHT CLEAR SKIES GRADUALLY GIVE WAY TO INCREASING CLOUDS
AND CHANCES OF LIGHT SNOW AND/OR SNOW SHOWERS ACROSS OUR
SOUTHWESTERN COUNTIES AS NEXT OCCLUDED FRONTAL ZONE PIVOTS SLOWLY
NORTHEASTWARD INTO OUR REGION. WITH LIGHT FLOW TRENDING SOUTHERLY
OVERNIGHT...LOW TEMPERATURES TO LIKELY TO OCCUR DURING THE FIRST
HALF OF THE NIGHT...THEN TREND STEADY OR SLOWLY RISE THEREAFTER.

&&

.LONG TERM /SATURDAY THROUGH WEDNESDAY/...
AS OF 312 PM EST WEDNESDAY...SFC HIGH PRESSURE AND RIDGING ALOFT
WILL SHIFT EAST TOWARDS THE ATLANTIC DURING THE DAY SATURDAY. A
WARM FRONT WILL APPROACH FROM THE S AND W. TWO SFC LOWS WILL
APPROACH THE NE...ONE NORTHERN STREAM TRAVERSING ACROSS THE
CENTRAL GREAT LAKES AND A SOUTHERN STREAM LOW MOVING UP THE
CAROLINAS UP TO THE DELMARVA AREA BY LATE SATURDAY. THE WARM
FRONT ASSOCIATED WITH THE FIRST SYSTEM WILL BRING CHC OF PRECIP
TO THE NORTH COUNTRY ON SATURDAY. ACTIVITY WILL BE SHOWERY AND
ONLY CHC AT THIS PT AS THE SECOND SYSTEM COULD BRING A DRY SLOT
TO ITS NORTHERN EDGE...DRYING MOISTURE ASSOCIATED WITH THE WARM
FRONT. SATURDAY NIGHT INTO SUNDAY...THE GREAT LAKES SYSTEM WILL
PHASE WITH THE COASTAL SYSTEM...WEAKENING BUT NOT COMPLETELY
COMBINING. THIS WILL KEEP CHC OF PRECIP OVER THE AREA THROUGHOUT
THE WEEKEND. THE UPPER LEVEL ENERGY FROM THE GREAT LAKES STORM
WILL MOVE OVER THE NORTH COUNTRY IN W-NW FLOW SUNDAY NT INTO
MONDAY...PRODUCING CLOUDS AND SLGT CHC TO LOW CHC FOR SHSN MAINLY
OVER THE HIGH TERRAIN. HIGH PRESSURE WILL BEGIN TO BUILD IN EARLY
MONDAY WITH RIDGING ALOFT CRESTING OVER THE REGION MONDAY NIGHT
INTO EARLY TUESDAY. A MORE POTENT SYSTEM ORIGINATING OVER THE
PACIFIC WILL STRENGTHEN IN THE LEE OF THE ROCKIES ON
MONDAY...GATHERING GULF MOISTURE EARLY NEXT WEEK AS IT MOVES
TOWARD THE NE. WAA AHEAD OF THE SYSTEM WILL BRING LOW CHC POPS IN
ON TUESDAY INTO TUESDAY NIGHT.

TEMPERATURES WILL BE ABOVE NORMAL WITH DAYTIME MAXES IN THE M30S-
L40S IN THE VALLEYS AND M20S-L30S IN THE HIGHER TERRAIN. THESE
WARM TEMPS DURING THE DAY WILL ALLOW SNOW TO MIX AND CHANGE TO
RAIN IN THE VALLEYS OVER THE WKND AFTNS. MIN TEMPS WILL GENERALLY
BE IN THE M20S IN THE VALLEYS AND TEENS IN THE HIGHER TERRAIN.

&&

.AVIATION /00Z THURSDAY THROUGH MONDAY/...
THROUGH 00Z FRIDAY...UPSLOPE SNOW SHOWERS WITH ASSOCIATED
MVFR/IFR VISIBILITIES WILL CONTINUE TO IMPACT MPV...MSS AND SLK.
THE REST OF THE TAF SITES WILL STAY VFR TO MVFR WITH BKN/OVC
CEILINGS BETWEEN 2.5-4.5KFT. AROUND 08Z OR SO...EXPECT THAT SOME
OF THE STEADIER SNOW ALONG THE WESTERN SLOPE OF THE GREEN
MOUNTAINS TO BEGIN TO FILL BACK IN TOWARDS BTV AND PERHAPS INTO
PBG AS FLOW OVER THE MOUNTAINS BECOMES BLOCKED. HAVE INDICATED
3-5SM VISIBILIITES FOR BTV AND PBG...THOUGH CAN'T RULE OUT IFR
VISIBILITIES ESPECIALLY FOR BTV. WEST WINDS WILL BECOME NORTHWEST
AROUND 7-10KTS DURING THE OVERNIGHT.

CEILINGS WILL CONTINUE TO STAY BROKEN/OVERCAST VFR/MVFR FOR THE
TAFS ON THURSDAY. EXPECT MOUNTAIN SNOW SHOWERS TO ALSO CONTINUE
TO AFFECT MPV AND SLK ON THURSDAY WITH POSSIBLE MVFR/IFR
CONDITIONS BUT HAVE ALSO SHOWN VCSH AT MSS...PBG AND BTV.
NORTHWEST WINDS CONTINUE AROUND 7-10KTS FOR THURSDAY.

OUTLOOK 00Z FRIDAY THROUGH MONDAY...

A VERTICALLY STACKED AREA OF LOW PRES AND THE ASSOCIATED CYCLONIC
UPSLOPE FLW WL RESULT IN OCCASIONAL SNOW SHOWER ACTIVITY THRU 06Z
FRIDAY. THIS COMBINED WITH SEVERAL EMBEDDED S/W'S WL PRODUCE
PERIODS OF SNOW SHOWERS WITH OCCASIONAL IFR LIKELY AT SLK/MPV AND
MVFR CONDITIONS POSSIBLE AT BTV/MSS/RUT/PBG. THE GREATEST CHC FOR
IFR CONDITIONS AT BTV/RUT/PBG WL BE ON THURSDAY. OTHERWISE...SFC
RIDGE AND IMPROVING CONDITIONS ARE ANTICIPATED ON FRIDAY. FROM
FRIDAY NIGHT THROUGH SUNDAY THERE WILL BE MORE CHANCES FOR SNOW
SHOWERS AND MVFR CONDITIONS. AT THIS POINT HARD TO PINPOINT
POSSIBILITY FOR IFR CONDITIONS WITH THIS SNOW. MONDAY WILL SEE A
RETURN TO HIGH PRESSURE.
