AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BURLINGTON VT
142 PM EST MON NOV 17 2025
SYNOPSIS
PERSISTENT NORTHWESTERLY FLOW AND A PROLONGED PERIOD OF UPSLOPE
SNOW ACROSS THE ADIRONDACKS AND GREENS IS EXPECTED FOR THE
FIRST HALF OF THE WEEK. SNOW SHOWERS WILL EVENTUALLY TAPER OFF
BY TUESDAY.
NEAR TERM /THROUGH TUESDAY NIGHT/
AS OF 130 PM EST MONDAY...AS LOW PRESSURE CONTINUES TO SHIFT
FURTHER EAST OF OUR REGION, SNOW SHOWER ACTIVITY HAS BEGUN TO
WIND DOWN. STILL THINK THAT SOME SORT OF LIGHT SNOW SHOWERS WILL
CONTINUE IN THE HIGH ELEVATIONS TONIGHT AND INTO TUESDAY, BUT
HAVE CANCELLED HEADLINES BECAUSE THE BULK OF THE ACCUMULATING
SNOW HAS ENDED. ANY ADDITIONAL ACCUMULATIONS WILL ONLY BE LIGHT.
WINDS WILL BEGIN TO DECREASE AS WELL WITH PRESSURE GRADIENT
SLACKENING AS LOW MOVES FURTHER AWAY FROM THE REGION. UNTIL THE
WINDS WEAKEN FURTHER, BLOWING SNOW AND LOWER VISIBILITIES WILL
BE POSSIBLE. MINIMUM TEMPERATURES OVERNIGHT WILL DIP INTO THE
UPPER TEENS TO UPPER 20S. WINDS WILL CONTINUE TO GUST 15 TO 25
MPH OVERNIGHT, AND WIND CHILLS WILL BE AS LOW AS THE SINGLE
DIGITS ABOVE ZERO IN THE ADIRONDACKS.
HIGH PRESSURE WILL BEGIN TO BUILD INTO THE REGION ON TUESDAY
AND LOWER LEVELS WILL DRY OUT, THEN SNOW SHOWERS WILL COMPLETELY
COME TO AN END. HIGH TEMPERATURES ON TUESDAY WILL RANGE FROM
THE LOWER 30S TO LOWER 40S. SOME PEEKS OF SUNSHINE ARE EXPECTED
BY THE AFTERNOON IN THE CHAMPLAIN VALLEY. LOWS OVERNIGHT TUESDAY
NIGHT WILL BE IN THE TEENS TO UPPER 20S.
SHORT TERM /WEDNESDAY THROUGH WEDNESDAY NIGHT/
AS OF 140 PM EST MONDAY...WEDNESDAY AND WEDNESDAY NIGHT WILL BE
QUIETER AS HIGH PRESSURE RIDGES INTO THE AREA. WILL HAVE SOME
WELCOME SUNSHINE ON WEDNESDAY AND HIGH TEMPERATURES WILL REACH
THE MID 30S TO LOWER 40S, LOWS WILL BE IN THE TEENS TO LOWER 20S
WITH GOOD RADIATIONAL COOLING.
LONG TERM /THURSDAY THROUGH MONDAY/
AS OF 1230 PM EST MONDAY...HIGH PRESSURE WILL CONTINUE OVERHEAD
BY MID TO LATE WEEK KEEPING TEMPERATURES ON THE MILD SIDE FOR
FALL STANDARDS. HIGHS TUESDAY AND FRIDAY WILL BE IN THE LOW 40S
WITH OVERNIGHT LOWS IN THE MID TO UPPER 20S TO NEAR 30. OUR FLOW
PATTERN BECOMES ZONAL AND SOUTHERLY BY THURSDAY WITH CONTINUED
DRYING, THOUGH STILL CLOUDY, CONDITIONS. OUR NEXT SYSTEM ARRIVES
FRIDAY, WITH NEW GUIDANCE SUGGESTING A DRIER SYSTEM WITH A
BREAK IN THE JET STREAM. WHILE THE GFS SHOWS A SINGLE JET STREAK
MOVING OVER THE REGION ASSOCIATED WITH THIS SYSTEM, THE ECMWF
DEPICTS TWO WEAKER STREAKS, ONE OVER THE NORTH COUNTRY, AND
ANOTHER TO OUR SOUTH MORE OVER THE MID-ATLANTIC. THIS BREAK IS
LOOKING MORE LIKLEY IN A RUN TO RUN ANALYSIS WHICH WOULD LEAD TO
A WEAKER MORE SCATTERY SYSTEM FOR FRIDAY INTO SATURDAY.
ENSEMBLE GUIDANCE VARIES FROM A FEW TENTHS TO A QUARTER TO HALF
AN INCH BETWEEN THE EPS AND GEFS. PRECIPITATION TYPE VARIABILITY
ALSO REMAINS, THOUGH LESS SO IN RECENT MODEL RUNS. SOME SHALLOW
RESIDUAL COLD AIR NEAR THE INTERNATIONAL BORDER AND NORTHEAST
KINGDOM, AND NEAR SUMMITS SHOULD BE ABLE TO KEEP SNOW FOR A FEW
HOURS FRIDAY BEFORE A SWITCH TO ALL RAIN OCCURS BY THE
AFTERNOON. A WINTRY MIX CANNOT BE RULED OUT IN THE COLD HOLLOWS
OF THE NORTHERN PORTIONS OF THE REGION AS WELL. FURTHERMORE,
BREAKS IN THE PRECIPITATION COULD LEAD TO SOME MIXED DOWN BREEZY
CONDITIONS FRIDAY INTO FRIDAY NIGHT BETWEEN SHOWERS. GUSTS
RIGHT NOW LOOK TO BE CONFINED TO THE HIGHER SUMMITS OF THE
ADIRONDACKS AND GREENS, AND LOCATIONS NEAR LAKE CHAMPLAIN. THE
SYSTEM QUICKLY EXITS THE AREA BY SATURDAY AFTERNOON WITH SOME
LIGHT LINGERING UPSLOPE RAIN/SNOW SHOWERS IN THE ADIRONDACKS AND
NORTHERN GREENS THROUGH THE WEEKEND AS CYCLONIC FLOW PERSISTS.
AVIATION /18Z MONDAY THROUGH SATURDAY/
THROUGH 18Z TUESDAY...A MIX OF MVFR AND VFR CONDITIONS EXIST
ACROSS THE REGION AS UPSLOPE SNOW CONTINUES BUT BEGINS TO
WEAKEN. UPSLOPE SNOW SHOWERS AT SLK/MPV/EFK WILL CONTINUE
THROUGH AT LEAST 00Z, AND PERHAPS TO 06Z AT EFK, HOWEVER, THE
INTENSITY OF THE SNOW IS BEGINNING TO WAIN AND TAPER DOWN. VSBYS
HAVE GENERALLY BEEN TO 3SM, WITH A FEW MINUTES POSSIBLE OF IFR
AT SLK, BUT NOT LONG ENOUGH TO MENTION IN THE TAF. VSBYS SHOULD
CONTINUE TO IMPROVE TOWARDS 6SM OVER THE NEXT FEW HOURS WITH
ONLY PROB30 GROUPS USED FOR ANY MORE MODERATE SNOW SHOWERS.
CEILINGS WILL REMAIN MVFR TO NEAR 2000FT AGL AT SLK/EFK/MPV AND
AT TIMES MSS, THROUGH THE TAF PERIOD. THERE COULD BE SOME
OCCASIONAL BREAKS AT MSS AT 3000FT AGL TOWARDS 06-12Z, BUT
PREVAILING CIGS SHOULD REMAIN MVFR. WEST/NORTHWEST WINDS WILL
CONTINUE TO BE BREEZY FOR THE NEXT 6HRS BEFORE GUSTS WEAKEN
TOWARDS 10-15KTS BY EARLY TOMORROW. WITH FROUDE NUMBERS STILL AT
OR ABOVE 1.25, FLOW WILL BE MOSTLY UNBLOCKED WHICH GIVES HIGHER
CONFIDENCE TO PREVAILING VFR CONDITIONS THROUGH THE TAF PERIOD
IN THE VALLEY SITES OF PBG/BTV/RUT. BRIEF LLWS NEAR THE MOUNTAIN
SUMMITS MAY LEAK TOWARDS SLK TONIGHT, BUT IT WILL BE SHORT
LIVED. IMPROVEMENTS AT ALL SITES TO VFR LOOK LIKELY BY THE END
OF THE TAF PERIOD TOMORROW.
