AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BURLINGTON VT
251 AM EST SUN NOV 16 2025
SYNOPSIS
ANY MIXED PRECIPITATION IS EXPECTED TO CHANGE TO RAIN OR SNOW EARLY
THIS MORNING, AND OUR ATTENTION TURNS TO PERSISTENT NORTHWESTERLY
FLOW AND A PROLONGED PERIOD OF UPSLOPE SNOW ACROSS THE ADIRONDACKS
AND GREENS FOR THE FIRST HALF OF THE WEEK. MODERATE TO HEAVY
SNOW AND GUSTY WINDS ARE EXPECTED, ESPECIALLY FOR NORTHWESTERN
SLOPES WITH SNOW ACCUMULATIONS AS HIGH AS 10 TO 18 FORECAST
THROUGH TOMORROW. SNOW SHOWERS WILL EVENTUALLY TAPER OFF BY
TUESDAY.
NEAR TERM /THROUGH MONDAY NIGHT/
AS OF 137 AM EST SUNDAY...
* THE WINTER WEATHER ADVISORY FOR MIXED PRECIPITATION REMAINS IN
EFFECT THIS MORNING FOR THE GREEN MOUNTAINS OF VERMONT AND
AREAS TO THEIR EAST AS THERE CONTINUES TO BE THE POTENTIAL FOR
A GLAZE OF FREEZING RAIN BEFORE DAWN THIS MORNING.
* A WINTER STORM WARNING HAS BEEN ISSUED FOR PORTIONS OF
NORTHERN NEW YORK AND VERMONT, BRINGING UP TO 10-18 INCHES OF
SNOW TO THE NORTHWESTERN SLOPES OF THE ADIRONDACKS AND GREENS.
* A WINTER WEATHER ADVISORY HAS BEEN ISSUED FOR PORTIONS OF
NORTHERN NEW YORK AND VERMONT WITH ACCUMULATIONS OF 2 TO 6
INCHES EXPECTED AND LOCALIZED 7 TO 9 INCHES POSSIBLE IN THE
MOUNTAINS.
* ROADS, AND ESPECIALLY BRIDGES AND OVERPASSES, WILL LIKELY
BECOME SLICK AND HAZARDOUS, MAKING TRAVEL DIFFICULT TO
IMPOSSIBLE FOR THE MONDAY MORNING AND EVENING COMMUTES,
PARTICULARLY IN WINTER STORM WARNING AREAS.
* STRONG WINDS OF 30-40 MPH COMBINED WITH THE WEIGHT OF SNOW ON
TREE LIMBS MAY DOWN POWER LINES AND COULD CAUSE SPORADIC POWER
OUTAGES, PARTICULARLY IN AREAS WE HAVE A WINTER STORM WARNING
IN EFFECT.
TEMPERATURES HAVE REACHED THE 30S ACROSS NORTHERN NEW YORK AND
VERMONT EARLY THIS MORNING. WHILE MOST PARTS OF NEW YORK AND THE
CHAMPLAIN VALLEY HAVE BECOME TOO MILD TO SUPPORT ANY APPRECIABLE
FREEZING RAIN, THERE ARE STILL COLD POCKETS ALONG AND EAST OF
THE GREENS THIS MORNING THAT COULD SEE MIXED PRECIPITATION AS
THE MILDER AIR OVERRUNS COLD AIR TRAPPED AT THE SURFACE, BUT
THE WINDOW FOR THIS POTENTIAL IS CLOSING SWIFTLY AND ANYTHING
THAT OCCURS WILL LIKELY BE ONLY A GLAZE.
DURING THE DAY TODAY, LOW PRESSURE MOVING OFF TO THE NORTHEAST
WILL BE PULLING COLD AIR INTO THE REGION FROM THE NORTHWEST.
HIGHS WILL LIKELY OCCUR EARLY IN THE DAY IN THE MID 30S TO MID
40S FOLLOWED BY TEMPERATURES FALLING THROUGH THE AFTERNOON,
ALLOWING FOR RAIN TO CHANGE OVER TO SNOW IN ALL LOCATIONS BY THE
END OF THE AFTERNOON. ROADS MAY BECOME SLICK AND TRAVEL WILL
BECOME DIFFICULT IN THE ADIRONDACKS BY THE EARLY AFTERNOON, AND
IN THE GREENS LIKELY BY THE END OF THE AFTERNOON TODAY. WINDS
AND COLD AIR ADVECTION WILL BE INCREASING TODAY WITH GRADIENTS
SUPPORTING GUSTS TO 20-40 MPH, PEAKING ON MONDAY MORNING. THIS
COULD RESULT IN SOME BLOWING SNOW ON THE MOUNTAINS AND EXTRA
STRESS ON ANY SNOW-LADEN TREE BRANCHES.
WITH LOWS FORECAST IN THE UPPER TEENS TO LOWER 30S SUNDAY
NIGHT, THIS COULD RESULT IN SOME SINGLE DIGIT WIND CHILLS IN THE
ADIRONDACKS AND TEENS/LOW 20S ELSEWHERE AS WELL AS BLOWING SNOW
ON MOUNTAIN PASSES. MONDAY WILL FEATURE SNOW SHOWERS BECOMING
MORE SCATTERED WITH HIGHS IN THE UPPER 20S AND 30S. SNOW RATIOS
MAKE FORECASTING SNOW AMOUNTS SLIGHTLY TRICKY, AS MODEL BLENDS
ARE PRODUCING RELATIVELY HIGH RATIOS FOR THE SCENARIO, BUT
HIGHER RESOLUTION MODELS ARE ALSO SHOWING SOME SUPPORT FOR THIS
SOLUTION. AT THE MOMENT, THINKING RATIOS START THE EVENT TODAY
IN THE 3 TO 11 TO 1 RANGE, ENDING MONDAY AROUND 13 TO 15 TO 1.
BY THE END OF THE DAY MONDAY, WE ANTICIPATE SNOW ACCUMULATIONS
WILL HAVE REACHED AS HIGH AS 10 TO 18 INCHES ON NORTHWESTERLY
SLOPES, THOUGH WIDER VALLEYS WILL LARGELY MISS OUT ON THESE HIGH
SNOW AMOUNTS WITH PERHAPS A HALF AN INCH TO 2 INCHES AT THE
LOWER ELEVATIONS.
SHORT TERM /TUESDAY/
AS OF 137 AM EST SUNDAY...UPSLOPE SNOW AND GUSTY GRADIENT
WINDS WILL LIKELY CONTINUE MONDAY NIGHT AND TUESDAY MORNING AS
LOW PRESSURE CURLS INTO ATLANTIC CANADA, THOUGH MUCH LESS
WIDESPREAD WITH COVERAGE AND INTENSITY DECREASING. AN ADDITIONAL
TRACE TO 3 INCHES IS POSSIBLE (HIGHEST AMOUNTS IN THE NORTHERN
GREENS) THROUGHOUT THE NIGHT AND EARLY MORNING WITH LOWS MONDAY
NIGHT IN THE UPPER TEENS TO UPPER 20S AND HIGHS TUESDAY IN THE
30S TO AND LOWER 40S.
LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/
AS OF 137 AM EST SUNDAY...START OF THIS PERIOD (TUESDAY NIGHT) STILL
UNDER NW CYCLONIC INFLUENCE FROM DEPARTING CANADIAN MARITIMES LOW
WITH SOME WEAK UPPER LEVEL AND SURFACE RIDGING ACROSS THE AREA FOR
WEDNESDAY THROUGH THURSDAY.
IT WILL BE DRY THROUGH THIS PERIOD BUT CONTINUED SEASONABLY
COLD...AKA 5 DEGS BELOW NORMAL FOR HIGHS BUT NEAR NORMAL FOR LOWS
DUE TO CLOUDS.
THEREAFTER, FOUR CORNERS SYSTEM LIFTS TOWARD CENTRAL CONUS BY FRIDAY
WITH OVERRUNNING POSSIBLE AS EARLY AS EARLY FRIDAY MORNING. AS UPPER
LEVEL AND SURFACE REFLECTION MOVES ACROSS OH RVR VLY AND GREAT LAKES
ON FRIDAY WILL SEE INCREASE IN PRECIPITATION CHANCES. INITIALLY,
THERE IS ENOUGH MARGINALLY COLD AIR FOR SOME MIXED SNOW AND RAIN,
PERHAPS SOME ICY MIX BUT HAVE TIME TO REFINE THAT PART OF THE
FORECAST FOR EARLY FRIDAY BUT STORM TRACK AND SOUTHERLY FLOW SHOULD
KEEP THINGS LIQUID FOR MUCH OF FRIDAY WITH COLD AIR ADVECTION ON THE
BACKEND TO REINTRODUCE RAIN-SNOW SHOWERS FRIDAY NIGHT- SATURDAY.
AVIATION /08Z SUNDAY THROUGH THURSDAY/
THROUGH 06Z MONDAY...CHANGING CONDITIONS THIS TAF PERIOD. WIDESPREAD
WINTRY MIX HAS EXITED THE AREA WITH MAYBE SOME RESIDUAL AT KEFK
THROUGH 12Z. MVFR-IFR CONDITIONS, MAINLY CIGS ACROSS THE REGION
WILL CONTINUE THROUGH 12Z WITH GRADUAL IMPROVEMENT POSSIBLE IN
THE WIDER VALLEYS LIKE KMSS,KPBG AND KBTV. UPSLOPE -SHSN WILL
DEVELOP IN NORTHERN NY 12-16Z AND THEN OVERSPREAD INTO VT
16-20Z. THIS WILL ALLOW FOR VFR-MVFR FOR WIDER VALLEYS BUT
LIKELY IFR-MVFR FOR TAF SITES NEAR THE HIGHER TERRAIN DUE TO
VSBY AND CIGS.
IT WILL BECOME BREEZY FROM THE WNW AT 15-25+KTS FOR THE DURATION
OF THE TAF AND LIKELY CONTINUING THROUGH MONDAY.
