SYSTEM HEADING INTO FRIDAY NIGHT. DAYTIME HIGHS WILL GENERALLY BE IN
THE 20S TO LOWER 30S, JUST A FEW DEGREES BELOW NORMAL FOR LATE

IS ANEMIC, SNOW AND TEMPERATURES WILL BE FALLING ACROSS MUCH OF
NORTHERN NEW YORK AND VERMONT. SLOW BUT CONSISTENT ACCUMULATIONS
WILL PERSIST THROUGH SATURDAY WITH 1-3 INCHES POSSIBLE. NOTICEABLY,
TEMPERATURES WILL BE DROPPING SHARPLY AS WELL WITH HIGHS WELL BELOW
SEASONAL AVERAGES FOR SATURDAY IN THE TEENS AND LOW/MID 20S. BREEZES

SUB-ZERO WIND CHILL TEMPERATURES FOR SOME LOCATIONS SATURDAY.
LONG TERM /SATURDAY NIGHT THROUGH WEDNESDAY/
AS OF 350 AM EST THURSDAY...MODEL CONSENSUS REMAINS STRONG FOR AN
ANOMALOUSLY STRONG HIGH PRESSURE TO MOVE OVER THE NORTH COUNTRY
SATURDAY NIGHT THROUGH EARLY MONDAY. PROGGED SLP OF 1030-1040MB ARE
COMMON ACROSS MODEL SUITES WITH SOME MODEST TIMING VARIANCES FOR
WHEN THE HIGH TRACKS ACROSS THE REGION. EITHER WAY, THE MESSAGE IS
THAT FRIGID WIND CHILLS ARE LIKELY ON THE LEADING EDGE WITH BREEZES
CONTINUING THROUGH SATURDAY NIGHT, ESPECIALLY FOR ELEVATIONS ABOVE
1000FT, -10 TO -15 APPARENT TEMPERATURES ARE POSSIBLE WITH 0 TO -10
APPARENT LOW TEMPERATURES FOR LOWER ELEVATIONS WITH COLD CONDITIONS

THE ADIRONDACKS AND POTENTIALLY NORTHEASTERN VERMONT. CLOUD COVER MAY
BE A FOIL WITH MODEL TIMING VARIANCES OF APPROACHING MID/UPPER LEVEL
CLOUDS POINTING TO A MODEST CHANCE OF SLIGHTLY WARMER LOWS FOR
NORTHERN NEW YORK SUNDAY NIGHT.
WHILE NO STRONG SYSTEMS ARE EXPECTED NEXT WEEK, UNSETTLED WEATHER IS
PROBABLE ONCE THE HIGH CLEARS OUT BY TUESDAY WITH ISOLATED TO
SCATTERED SNOW SHOWERS. COLDEST TEMPERATURES SHOULD MODERATE BACK
TOWARDS SEASONAL NORMALS TOWARDS MID WEEK WITH PERIODS OF SOUTHERLY
FLOW PROMOTING HIGHS BACK INTO THE UPPER 20S/LOWER 30S BY CHRISTMAS
DAY. QUESTIONS REMAIN FOR CHARACTER OF PRECIPITATION FOR LATE NEXT
WEEK WITH SOME MODELS SUPPORTING ENOUGH WARMING FOR RAIN CHANCES AND
OTHERS KEEPING TEMPERATURES COOLER.
