NATIONAL WEATHER SERVICE ALBANY NY
642 PM EST SUN DEC 14 2025
UPDATE
AS OF 630 PM EST, AREA OF SNOW SHOWERS ACROSS NORTHERN TACONICS
AND SOUTHERN VT CONTINUING TO TRACK SOUTH/SOUTHEAST, PROVIDING A
RENEWED BURST OF SNOW OVER THE NEXT 1-2 HOURS, EVENTUALLY
REACHING THE NORTHERN BERKSHIRES. A QUICK COATING TO UP TO AN
INCH COULD OCCUR, ESPECIALLY ACROSS HIGHER ELEVATIONS OF THE
SOUTHERN GREENS. OTHERWISE, FORECAST REMAINS ON TRACK WITH CLEAR
TO PARTLY CLOUDY SKIES AND VERY COLD/BLUSTERY CONDITIONS.
SYNOPSIS
MUCH COLDER AND BLUSTERY CONDITIONS EXPECTED THROUGH MONDAY.
TEMPERATURES FINALLY TREND MILDER FOR THE END OF THE WEEK WITH
WIDESPREAD RAINFALL LIKELY THURSDAY NIGHT INTO FRIDAY ALONG WITH
GUSTY WINDS.
SHORT TERM /THROUGH MONDAY NIGHT/
KEY MESSAGES:
- THE COMBINATION OF BREEZY WINDS AND FRIGID TEMPERATURES WILL
LEAD TO DANGEROUS FEEL-LIKE TEMPERATURES RANGING FROM -10F TO
-20F TONIGHT INTO MONDAY MORNING.
DISCUSSION:
OUR PARENT TROUGH WILL CONTINUE SWINGING THROUGH THE NORTHEAST
TODAY WITH SOME LINGERING SNOW SHOWERS CONTINUING TODAY,
ESPECIALLY IN THE HIGHER TERRAIN AREAS. THERE WAS EVEN SOME WEAK
HUDSON MOHAWK CONVERGENCE IN THE CAPITAL DISTRICT THAT LED TO
BRIEF ENHANCEMENT OF SNOW SHOWERS THIS MORNING. AS THE MAIN
TROUGH AXIS AND SFC COLD FRONT PUSH THROUGH THE REGION THIS
AFTERNOON, NORTHWEST WINDS WILL TURN BREEZY AND ADVECT AN ARCTIC
AIR MASS INTO THE NORTHEAST. TEMPERATURES TODAY WILL NOT RISE
OUT OF THE 20S AND AS THE CORE THE COLD ADVECTS EASTWARD TONIGHT
WITH 850HPA ISOTHERMS DROPPING TO -15C TO -18C (OR 2 TO 3 STD
DEVIATION BELOW NORMAL PER THE NAEFS), OVERNIGHT TEMPERATURES
WILL TURN FRIGID. PROBABILISTIC GUIDANCE SHOWS GREATER THAN AN
80% CHANCE FOR NEARLY THE ENTIRE REGION TO DROP UNDER 10 DEGREES
BY MONDAY MORNING. WITH NORTHWEST WINDS REMAINING ELEVATED
TONIGHT WITH GUSTS UP TO 15-30MPH (STRONGEST IN THE EASTERN
CATSKILLS, TACONICS, LITCHFIELD HILLS AND BERKSHIRES), THE
COMBINATION OF THE COLD TEMPERATURES AND WINDS WILL RESULT IN
DANGEROUS WIND CHILL OR "FEEL-LIKE" TEMPERATURES FALLING TO -5F
TO -15F LATE TONIGHT THROUGH MONDAY MORNING. WESTERN MA AND
NORTHERN LITCHFIELD COUNTY LOOK TO HAVE THE HIGHEST CHANCE OF
NEARING THEIR COLD WEATHER ADVISORY CRITERIA (-15F AND -10F,
RESPECTIVELY) SO ISSUED THE PRODUCT FROM MIDNIGHT TONIGHT
THROUGH 9AM TOMORROW MORNING. THE EASTERN CATSKILLS ARE ALSO
CLOSE TO THEIR CRITERIA BUT GIVEN THAT THE
-15F VALUES ARE REALLY FOR THE HIGHEST TERRAIN AREAS, WE HELD
OFF. REGARDLESS OF WHETHER OR NOT AN AREA IS IN A COLD WEATHER
ADVISORY OR NOT, DRESS WARMLY AND IN LAYERS FOR YOUR MONDAY
MORNING COMMUTE AND AVOID PROLONGED EXPOSURE TO THE COLD.
THE ADVECTIVE COLD REGIME CONTINUES THROUGH THE DAY ON MONDAY
WITH TEMPERATURES STRUGGLING TO WARM THROUGH THE DAY. IN FACT,
OUTSIDE OF THE MID-HUDSON VALLEY, THERE IS LESS THAN A 10%
CHANCE THAT HIGH TEMPERATURES TOMORROW WILL EXCEED 25 DEGREES.
GIVEN THAT NORTHWEST WINDS REMAIN BREEZY THROUGH THE DAY WITH
GUSTS UP TO 15-25MPH, THE FEEL-LIKE TEMPERATURES WILL REMAIN
CHILLY THROUGH THE DAY IN THE SINGLE DIGITS AND TEENS. A
WEAKENING SHORTWAVE AND SOME ENHANCED MID-LEVEL MOISTURE WILL
PUSH INTO THE REGION MONDAY AFTERNOON RESULTING IN MORNING SUN
FADING BEHIND INCREASING CLOUDS. OVERALL MOISTURE AND FORCING IS
LIMITED SO BEST CHANCE FOR ANY SNOW SHOWERS LOOKS TO BE IN THE SOUTHERN
GREEN WHERE UPSLOPE CAN ENHANCE FORCING FOR ASCENT. EVEN STILL,
ONLY EXPECTING COATING TO 0.5" OF SNOW. BEHIND THE SHORTWAVE,
WEST TO SOUTHWEST FLOW QUICKLY DEVELOPS AND ALIGNS DOWN THE LONG
FETCH OF LAKE ONTARIO. THIS WILL ELICIT A LAKE EFFECT RESPONSE
WITH A SINGLE LAKE BAND DEVELOPING AND BECOMING DIRECTED INTO
NORTHERN HERKIMER COUNTY (MAINLY NORTH OF ROUTE 28) BY 21 UTC
MON - 00 UTC TUES. WITH INVERSION HEIGHTS REMAIN RATHER HIGH
NEAR 700HPA MONDAY EVENING, THE BAND LOOKS TO PRODUCE MODERATE
TO HEAVY SNOW FOR FEW HOURS WITH THE HREF SHOWING 10 TO 30%
CHANCE FOR 1" PER HOUR SNOWFALL RATES FROM 00-04 UTC. BY 06 - 09
UTC, MOISTURE STARTS DWINDLING AND INVERSION HEIGHTS SLOWLY
START DROPPING SO THE BAND BEGINS TO WEAKEN BEFORE FALLING APART
BY EARLY TUESDAY MORNING. TOTAL SNOWFALL AMOUNTS LOOKS TO RANGE
2 TO 5 INCHES BUT GIVEN THAT MOST ACCUMULATIONS WILL REMAIN
NORTH OF OLD FORGE, WILL LIKELY NOT NEED A WINTER WEATHER
ADVISORY. OTHERWISE, MONDAY NIGHT REMAINS CHILLY IN THE SINGLE
DIGITS AND TEENS ALBEIT NOT QUITE AS COLD AS SUNDAY NIGHT AS THE
CORE OF THE ARCTIC AIR ESCAPES TO OUR EAST.
LONG TERM /TUESDAY THROUGH SUNDAY/
KEY MESSAGES:
- TEMPERATURES TREND MILDER MIDDLE TO END OF THIS NEXT WEEK.
- INCREASING CONFIDENCE FOR WIDESPREAD PRECIPITATION, MAINLY
RAIN, ALONG WITH GUSTY WINDS LATE THURSDAY INTO FRIDAY.
DISCUSSION:
QUIET WEATHER ENSUES TUESDAY THROUGH WEDNESDAY AS ZONAL FLOW AND
SFC HIGH PRESSURE BUILDS OVER THE NORTHEAST. A PROGRESSIVE YET
MOISTURE STARVED SHORTWAVE TROUGH TRACKS ACROSS THE NORTHEAST
FOR WEDNESDAY INTO WED NIGHT BUT NOT EXPECTING MORE THAN SOME
BRIEF SNOW SHOWERS MAINLY FOR AREAS NORTH AND WEST OF THE
CAPITAL DISTRICT GIVEN VERY LACKLUSTER MOISTURE.
OUR ATTENTION THEN TURNS TO NEARLY FULL LATITUDE TROUGH TRACKING
ACROSS THE COUNTRY FOR THE MIDDLE TO END OF NEXT WEEK. LARGE
SCALE RIDGING AMPLIFIES ACROSS THE NORTHEAST WED NIGHT INTO
THURSDAY AHEAD OF IT WITH STRONG SOUTHWESTERLY WINDS USHERING
IN A MUCH MILDER AIR MASS INTO THE REGION. WITH A 75 TO 90%
CHANCE FOR HIGH TEMPERATURES TO EXCEED 40 DEGREES ON THURSDAY,
IT WILL FEEL QUITE MILD GIVEN THE COLDER THAN NORMAL DECEMBER
WE HAVE ENDURED (ALBANY MONTH TO DATE AVG TEMPERATURE IS -8F
BELOW NORMAL). BESIDE MILDER TEMPERATURES, WE WILL NEED TO
MONITOR GUSTY SOUTHERLY WINDS AS THE LATEST PROBABILISTIC
GUIDANCE SHOWS 40 TO 70% CHANCE FOR WIND GUSTS TO EXCEED 35MPH
OVER THE 24-HR PERIOD FROM 1AM THURS TO 1AM FRI. AS THE INCOMING
TROUGH BECOMES NEUTRAL TO EVEN SLIGHTLY NEGATIVELY TILTED,
STRONG HEIGHT FALLS COMBINED WITH IMPRESSIVE MOISTURE TRANSPORT
WILL LIKELY RESULT IN WIDESPREAD RAINFALL THURS NIGHT INTO EARLY
FRIDAY. GIVEN THE MILD AIR MASS AHEAD OF THE TROUGH AND LATEST
TRENDS SHOWING THE MAIN COLD FRONT HANGING BACK UNTIL EARLY
FRIDAY, P-TYPE IS LIKELY MAINLY RAIN. LOCALLY MODERATE TO HEAVY
RAIN RATES LOOK POSSIBLE GIVEN THAT THE STRONG KINEMATICS LOOK
TO DIRECT A MOISTURE PLUME OUT OF THE GULF INTO THE NORTHEAST;
HOWEVER, FLOODING LOOKS UNLIKELY AS EVEN THE 90TH PERCENTILE 24
HOUR PRECIPITATION AMOUNTS ARE UNDER 2 INCHES AND THE INCOMING
WARMTH WILL LIKELY NOT BE STRONG ENOUGH OR LONG-LIVED ENOUGH TO
RIPEN/MELT THE EXISTING SNOW PACK. COOLER TEMPERATURES AND
STRONG, GUSTY WINDS RETURN FOR FRIDAY AS THE MAIN COLD FRONT
MARCHES THROUGH USHERING IN ANOTHER CANADIAN AIR MASS. WILL NEED
TO MONITOR NORTHWEST WIND GUSTS ON FRIDAY AS LATEST
PROBABILISTIC GUIDANCE SHOWS 40 TO 70% CHANCE FOR 40MPH OR
HIGHER GUSTS FROM 1AM FRI TO 1AM SAT.
AVIATION /00Z MONDAY THROUGH FRIDAY/
THROUGH 00Z/TUE, MAINLY VFR CONDITIONS ARE EXPECTED, ALTHOUGH
SOME BRIEF MVFR VSBYS/CIGS COULD OCCUR THIS EVENING AND AGAIN
LATER TONIGHT AT KPSF AS SOME SNOW SHOWERS PASS THROUGH EARLY,
AND ADDITIONAL MVFR-LEVEL PATCHES POTENTIALLY DEVELOPING LATER
TONIGHT. AS AN UPPER LEVEL DISTURBANCE TRACKS ACROSS THE TAF
SITES MONDAY AFTERNOON, MAINLY VFR LEVEL CLOUDS ARE EXPECTED.
HOWEVER, CAN NOT RULE OUT SOME MVFR CIGS/VSBYS AT KPSF IN THE
AFTERNOON AS SOME SNOW SHOWERS/FLURRIES MAY DEVELOP.
WEST/NORTHWEST WINDS 8-14 KT WITH OCCASIONAL GUSTS OF 20-25 KT
EXPECTED THROUGH MIDNIGHT. WINDS MAY DECREASE AFTER MIDNIGHT AT
KGFL AND KPOU, ALLOWING FOR POTENTIAL LOW LEVEL WIND SHEAR AS
WINDS AROUND 2000 FT AGL REMAIN STRONG FROM THE NORTHWEST AT
30-40 KT. WEST/NORTHWEST WINDS 8-14 KT WITH GUSTS OF 20-25 KT
WILL THEN REDEVELOP MONDAY MORNING AND WILL PERSIST THROUGH
EARLY AFTERNOON, BEFORE GRADUALLY BACKING INTO THE WEST TO
SOUTHWEST AND DECREASING TO 5-10 KT BY SUNSET.
