NY AND MOST OF WESTERN NEW ENGLAND. HOWEVER, WINTER WEATHER
ADVISORY FOR LITCHFIELD COUNTY CT REMAINS IN EFFECT FOR 7 AM
THROUGH 10 PM SUNDAY. ALSO, ADDED IN MENTION OF PATCHY FOG

INCREASE ONCE AGAIN LATER TONIGHT.

SHOWERS AND FLURRIES BY THIS EVENING. SNOW COVERED ROADWAYS AND
LOW VISIBILITY WILL CONTINUE TO MAKE FOR LOCALLY HAZARDOUS
TRAVEL THROUGH THE EARLY EVENING.
2) A COASTAL LOW PRESSURE SYSTEM WILL BRING A LIGHT SNOW
ACCUMULATION TO SOUTHEASTERN AREAS FOR SUNDAY INTO SUNDAY
EVENING ALLOWING FOR SOME HAZARDOUS TRAVEL OVER NORTHWESTERN
CONNECTICUT.
3) BELOW NORMAL TEMPERATURES ARE EXPECTED FOR MUCH OF NEXT WEEK
ALONG WITH OPPORTUNITIES FOR SNOWFALL FROM BOTH LAKE EFFECT AND
PASSING CLIPPER SYSTEMS.
DISCUSSION
KEY MESSAGE 1...
AS A RESULT AN APPROACHING UPPER LEVEL TROUGH AND WARM ADVECTION
WITHIN THE SOUTHWEST FLOW ALOFT, STEADY SNOWFALL HAS BEEN
ONGOING THIS MORNING. THIS SNOWFALL HAS BEEN LIGHT TO
OCCASIONALLY MODERATE AT TIMES, WITH THE HEAVIEST TOTALS MAINLY
SOUTH AND EAST OF THE CAPITAL REGION. TOTALS HAVE RANGED
GENERALLY IN THE 1 TO 3 INCHES SO FAR, ALTHOUGH SOME SPOTS HAVE
ALREADY SEEN UP TO 5 INCHES, MAINLY OVER THE BERKSHIRES.
BASED ON RADAR IMAGERY AND CAMS, THE STEADY SNOWFALL SHOULD BE
WINDING DOWN OVER THE NEXT FEW HOURS, AS THE BEST LIFT SHIFTS
NORTHEAST OF THE REGION. MOST OF THE STEADY SNOW WILL TAPER TO
SNOW SHOWERS AND FLURRIES BY THE MID TO LATE AFTERNOON HOURS. A
FEW ADDITIONAL INCHES ARE POSSIBLE (MAINLY FOR EASTERN AREAS)
THROUGH THAT TIME. STORM TOTAL AMOUNTS WILL GENERALLY BE IN THE
2 TO 6 INCH RANGE, BUT A SPOTS IN SOUTHERN VT AND THE BERKSHIRES
MAY SEE 7 OR 8 WITHIN THE HIGHEST TERRAIN. THROUGH THE EARLY
EVENING HOURS, SNOW COVERED ROADWAYS AND REDUCED VISIBILITY WILL
MAKE TRAVEL HAZARDOUS, ESPECIALLY ON UNTREATED ROADWAYS AND ACROSS
THE HIGHER TERRAIN. FOR MOST AREAS, LIGHT WINDS SHOULD PREVENT
MUCH BLOWING AND DRIFTING FROM OCCURRING, ALTHOUGH SOUTHERLY
WINDS MAY BE LOCALLY STRONGER WITHIN THE IMMEDIATE HUDSON
VALLEY. AS SNOW TAPERS OFF, TEMPS MAY WARM INTO THE MID 30S IN
VALLEY AREAS, WHICH MAY ALLOW FOR SOME MELTING AS WELL. WINTER
WEATHER ADVISORY WILL REMAIN IN EFFECT FOR MUCH OF THE REGION
THROUGH 7 PM THIS EVENING.
KEY MESSAGE 2...
AN AREA OF LOW PRESSURE WILL BE DEVELOPING OVER THE SOUTHEASTERN
US TONIGHT AND IT WILL BE QUICKLY LIFTING NORTHEAST OFF THE
EASTERN SEABOARD FOR SUNDAY. AT THE SAME TIME, A COLD FRONT WILL
BE PASSING ACROSS UPSTATE NEW YORK FOR TONIGHT. THE COMBINATION
OF SOME WARM ADVECTION AHEAD OF THE DEVELOPING COASTAL LOW,
AIDED BY A STRONG JET STREAK ALOFT AND THE APPROACHING SURFACE
FRONT AND UPPER LEVEL TROUGH TO THE WEST WILL ALLOW ANOTHER AREA
OF LIGHT STEADY SNOWFALL TO DEVELOP FOR LATE TONIGHT AND INTO
SUNDAY MORNING, MAINLY FOR SOUTHEASTERN AREAS (THE CATSKILLS,
MID HUDSON VALLEY, TACONICS, BERKSHIRES AND NW CT). SOME
ACTIVITY MAY REACH AS FAR NORTHWEST AS THE CAPITAL REGION. AS
THE COASTAL LOW CONTINUES TO STRENGTHEN, AN ADDITIONAL SURGE OF
LIGHT SNOW WILL SPREAD NORTHWEST INTO OUR AREA FOR LATER SUNDAY
INTO SUNDAY EVENING. AGAIN, THIS WILL PRIMARILY IMPACT
SOUTHEASTERN AREAS, GENERALLY FROM THE CAPITAL REGION ON SOUTH
AND EAST. MOST SNOW SHOULD BE DONE IN OUR AREA BY THE LATE
EVENING HOURS ON SUNDAY.
TOTAL SNOWFALL THROUGH SUNDAY WILL BE LIGHT FOR MOST PLACES (A
COATING TO TWO INCHES FOR MOST SPOTS). SLIGHTLY HIGHER TOTALS
ARE EXPECTED IN FAR SOUTHEASTERN DUTCHESS COUNTY, BERKSHIRE
COUNTY AND LITCHFIELD COUNTY, WHERE 2-3 INCHES IS EXPECTED. A
FEW SPOTS IN FAR SOUTHERN LITCHFIELD COUNTY MAY SEE AROUND 4
INCHES. BASED ON EXPECTED TOTALS, HAVE ISSUED A WINTER WEATHER
ADVISORY FOR LITCHFIELD COUNTY. SOME HAZARDOUS TRAVEL IS
POSSIBLE, MAINLY SUNDAY MORNING AND AGAIN LATE SUNDAY.
KEY MESSAGE 3...
A COLD PATTERN IS EXPECTED THROUGH MUCH OF THE UPCOMING WEEK
THANKS TO A LARGE UPPER LEVEL TROUGH CENTERED OVER THE
NORTHEASTERN US. WITH THE COLD AIR IN PLACE, LAKE EFFECT SNOW
WILL LIKELY DEVELOP AND PERSIST THROUGH MUCH OF THE WEEK AS
WELL AND A FEW FAST MOVING CLIPPER SYSTEMS WILL ALSO IMPACT THE
REGION AS WELL.
A CLIPPER SYSTEM WILL BE MOVING THROUGH EARLY IN THE WEEK, WHICH
SHOULD ALLOW FOR A BAND OF LAKE-EFFECT SNOW TO DEVELOP AND
IMPACT THE WESTERN ADIRONDACKS FOR MONDAY NIGHT INTO TUESDAY.
DEPENDING ON THE PERSISTENCE OF THE BAND, A LAKE EFFECT SNOW
WARNING MAY BE NEEDED FOR NORTHERN HERKIMER AND HAMILTON
COUNTIES DURING THIS TIME, AS A SINGLE BAND OF LAKE-EFFECT
LOOKS TO DEVELOP. 850 HPA TEMPS WILL BE CLOSE TO -20 C AS WELL,
MAKING FOR RATHER FRIGID TEMPS. MOST AREAS WILL BE DOWN INTO THE
SINGLE DIGITS AND TEENS ON MONDAY NIGHT AND GUSTY WESTERLY WINDS
WILL MAKE IT FEEL EVEN COLDER. WIND CHILL VALUES WILL LIKELY BE
BELOW ZERO FOR MANY AREAS. HIGHS ON TUESDAY WILL ONLY BE IN THE
TEENS TO LOW 20S, MAKING FOR A RATHER FRIGID DAY AS WELL.
THE NEXT CLIPPER WILL PASS THROUGH AROUND WEDNESDAY NIGHT OR
THURSDAY WITH SOME WIDESPREAD SNOW SHOWERS. BEHIND THIS SYSTEM,
ANOTHER ROUND OF COLD TEMPS AND LAKE EFFECT LOOKS TO OCCUR ONCE
AGAIN FOR THE LATE WEEK.
AVIATION /06Z SUNDAY THROUGH THURSDAY/
THROUGH 06Z MONDAY...PATCHY LOW CLOUDS WITH IFR CIGS STILL
LINGERING IN THE HUDSON VALLEY AND AFFECTING KALB/KGFL/KPOU.
THE LOW CLOUDS SHOULD START TO SCOUR OUT BETWEEN 07Z-09Z, AS A
SURFACE TROUGH APPROACHES FROM THE WEST AND MIXES OUT THE LOWER
CLOUDS. SO OTHER THAN PATCHY MIST WITH 5-6 SM VSBY BENEATH THE
THICKER MID LEVEL CLOUDS OVERNIGHT, CIGS ARE EXPECTED TO
IMPROVE TO VFR LEVELS. HOWEVER, THE NEXT DISTURBANCE WILL
ALREADY BE APPROACHING BY 11Z-12Z WITH LIGHT SNOW EXPECTED TO
DEVELOP. BEST CHANCE FOR IFR CONDITIONS THIS MORNING WILL BE AT
KPOU/KPSF, WITH SOME OCCASIONAL IFR POSSIBLE AT KALB AND MVFR
AT KGFL. THERE MAY BE YET ANOTHER BRIEF BREAK IN THE SNOW THIS
AFTERNOON, BEFORE SNOW RE-DEVELOPS TOWARDS 23Z AS A DEVELOPING
STORM OFF THE COAST STRENGTHENS AND SPREADS SNOW BACK INTO THE
AREA. IFR CONDITIONS EXPECTED THIS EVENING AT KALB/KPOU/KPSF,
WITH MAINLY MVFR AT KGFL. WILL CONTINUE TO MONITOR TRENDS WITH
THIS ACTIVE 24 HOUR PERIOD AHEAD. WINDS WILL BE LIGHT AND
VARIABLE BECOMING NORTH-NORTHWEST AROUND 5 KT THIS AFTERNOON.
