AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE ALBANY NY
624 AM EST SAT DEC 13 2025
SYNOPSIS
AN APPROACHING DISTURBANCE WILL BRING SNOW SHOWERS TO AREAS
FROM MAINLY I-90 NORTH TODAY. ANOTHER DISTURBANCE WILL BRING A
LIGHT SNOW ACCUMULATION TO AREAS MAINLY SOUTH OF ALBANY TONIGHT
INTO EARLY SUNDAY. AN ARCTIC COLD FRONT WILL PUSH THROUGH ON
SUNDAY, RESULTING IN COLDER AND BLUSTERY CONDITIONS RETURNING
SUNDAY NIGHT INTO MONDAY.
SHORT TERM /THROUGH SUNDAY/
KEY MESSAGES:
- HIGH CONFIDENCE IN BELOW NORMAL TEMPERATURES CONTINUING
THROUGH THE WEEKEND.
- A DISTURBANCE WILL BRING LIGHT SNOW TO AREAS MAINLY SOUTH OF
ALBANY TONIGHT INTO EARLY SUNDAY. THERE IS A 40-70% CHANCE OF
AT LEAST 2" OF SNOW.
DISCUSSION:
AS OF 200 AM, RADAR AND WEBCAMS INDICATING A FEW LEFTOVER LAKE
EFFECT FLURRIES OVER THE NW ADIRONDACKS, OTHERWISE DRY
CONDITIONS IN PLACE WITH SATELLITE IMAGERY SHOWING PLENTY OF
CLOUDS FROM AROUND I-90 NORTH. WATER VAPOR SHOWS A POTENT LEAD
SHORT WAVE (ASSOCIATED WITH A LARGER UPPER LOW/THOUGH OVER THE
UPPER GREAT LAKES) MOVING THROUGH MICHIGAN/LAKE HURON AT THIS
TIME. THIS SYSTEM WILL CONTINUE TO TRACK EAST ACROSS OUR AREA
TODAY, BRINGING SNOW SHOWERS FROM AROUND MID MORNING INTO THE
AFTERNOON. SNOW SHOWERS WILL BE SCATTERED AROUND THE I-90
CORRIDOR, BUT MORE WIDESPREAD IN THE W. MOHAWK VALLEY AND SW.
ADIRONDACKS WHERE S-SW UPSLOPE FLOW ALOFT WILL ENHANCE LIFT.
MOST OF THE AREA WILL HAVE < 1" OF SNOW, WITH 1-2" IN THE SW.
ADIRONDACKS. TEMPERATURES WILL REMAIN SLIGHTLY BELOW NORMAL
TODAY, WITH HIGHS MAINLY IN THE UPPER 20S TO MID 30S. A
SOUTHERLY BREEZE WILL GUST AROUND 10-20 MPH AT TIMES.
SOME BRIEF LAKE EFFECT SNOW SHOWERS WILL MOVE ACROSS PARTS OF
THE W/SW ADIRONDACKS EARLY THIS EVENING AS WESTERLY FLOW BRIEFLY
ALIGNS. THEN, AS THE UPSTREAM POSITIVELY TILTED UPPER
LOW/TROUGH OVER THE GREAT LAKES STARTS TO SHIFT SE, A POTENT
SHORT WAVE ROUNDING THE BASE OF THE TROUGH TRACKS INTO THE OHIO
VALLEY. FORCING AHEAD OF THIS DISTURBANCE ALONG WITH LIMITED
CYCLOGENESIS OFF THE MID ATLANTIC COAST WILL BRING A PERIOD OF
STEADY LIGHT SNOW TO AREAS MAINLY SOUTH OF ALBANY FROM LATE THIS
EVENING TO EARLY SUN MORNING. NOT MUCH CHANGE FROM THE PRIOR
FORECAST, WITH 1-2" SNOW FOR AREAS SOUTH/EAST OF ALBANY AND
< 1" FROM ALBANY NORTH/WEST. NBM PROBS FOR > 3" ARE ONLY 20-40%
FOR SE AREAS, SO THERE IS HIGH CONFIDENCE THIS WILL BE A MINOR
EVENT. THE SNOW WILL BE DRY/FLUFFY TOO WITH SNOW-LIQUID RATIOS
OF 15:1 TO 20:1. LOWS WILL RANGE FROM THE SINGLE DIGITS IN THE
MOUNTAINS TO 10S/LOWER 20S IN THE VALLEYS.
THE STEADY LIGHT SNOW SE OF ALBANY SHOULD TAPER OFF AN HOUR OR
TWO AFTER SUNRISE, WITH MAINLY DRY CONDITIONS THEREAFTER. THE
ONLY EXCEPTION WILL BE SCATTERED SNOW SHOWERS DEVELOPING ALONG
AN ARCTIC COLD FRONT THAT WILL PUSH SOUTHWARD ACROSS THE AREA
DURING THE AFTERNOON. THE SNOW SHOWERS SHOULD MAINLY BE TIED TO
AREAS WEST OF THE HUDSON VALLEY. HIGHS WILL RANGE FROM THE 10S
TO UPPER 20S. TEMPERATURES WILL DROP CONSIDERABLY AS AN ARCTIC
AIR MASS FILTERS IN SUN NIGHT. LOWS EXPECTED TO RANGE FROM
AROUND 0F TO AROUND 10F, BUT A PERSISTENT NW BREEZE WILL RESULT
IN WIND CHILLS OR FEELS-LIKE TEMPERATURES AS COLD AS -15F IN
HIGHER TERRAIN AREAS AND -5F TO +5F IN LOWER ELEVATIONS. SOME
MOUNTAIN AREAS COULD GET CLOSE TO COLD WEATHER ADVISORY. WILL
CONTINUE TO MONITOR TRENDS. WITH THE NW FLOW, ANY LAKE EFFECT
SNOW SHOULD BE LIMITED TO CENTRAL NY.
LONG TERM /SUNDAY NIGHT THROUGH FRIDAY/
KEY MESSAGE:
- COLD TEMPERATURES PERSIST THROUGH EARLY NEXT WEEK, WITH A
WARMUP EXPECTED MID TO LATE WEEK.
- A STORM SYSTEM MAY BRING WIDESPREAD PRECIPITATION, INCLUDING
MAINLY RAIN, LATER NEXT WEEK.
DISCUSSION:
A COLD AIR MASS WILL REMAIN ENTRENCHED ACROSS THE REGION
THROUGH EARLY NEXT WEEK, RESULTING IN BELOW NORMAL TEMPERATURE
CONTINUING. THE NEXT CHANCE OF SNOW SHOWERS ARRIVES LATE MON
P.M. INTO MON NIGHT, AS ANOTHER DISTURBANCE APPROACHING FROM THE
GREAT LAKES TRACKS SE ACROSS OUR AREA. WILL MENTION SCATTERED
SNOW SHOWERS FOR MOST, BUT MORE WIDESPREAD ACTIVITY EXPECTED
WEST OF THE HUDSON VALLEY DUE TO LAKE EFFECT/UPSLOPE
ENHANCEMENT. SOME SPOTS IN THE W. ADIRONDACKS COULD GET 1-2" OF
SNOW, WITH < 1" ELSEWHERE. SOME BRIEF LAKE EFFECT MAY OCCUR
BEHIND THIS SYSTEM INTO EARLY TUE, THEN DRY CONDITIONS TAKE HOLD
WITH SURFACE RIDGING MOVING IN, ALTHOUGH IT WILL REMAIN COLD.
A MORE ZONAL FLOW REGIME ALOFT DEVELOPS BY WED, WITH A
DEVELOPING SW FLOW EXPECTED TO RESULT IN MILDER TEMPERATURES AT
LEAST GETTING BACK TO NORMAL LEVELS WED AFTERNOON (LOWER 30S TO
LOWER 40S). EVEN WARMER TEMPERATURES COULD OCCUR ON THU AS
SOUTHERLY FLOW STRENGTHENS AHEAD OF A POTENTIALLY STRONG COLD
FRONT APPROACHING FROM THE WEST. NBM MAINTAINING HIGHS IN THE
UPPER 30S TO MID 40S, WHICH SEEMS REASONABLE AT THIS TIME.
PRECIP CHANCES ALSO RISE CONSIDERABLY THU INTO THU NIGHT. AT
THIS TIME TEMPERATURES LOOK WARM ENOUGH FOR RAIN AT LOWER
ELEVATIONS, BUT THERE COULD BE SOME SORT OF WINTRY MIX OR SNOW
IN SOME HIGHER TERRAIN AREAS. WILL MENTION RAIN/SNOW FOR NOW DUE
TO UNCERTAINTY AND REFINE FORECAST DETAILS AS WE GET CLOSER.
TEMPERATURES LOOK TO COOL BACK DOWN BY FRI IN WAKE OF THE COLD
FRONT. DEPENDING ON EVENTUAL STRENGTH OF WINDS ALOFT, WINDS
COULD GET QUITE GUSTY IN THE WESTERLY COLD ADVECTION REGIME.
AVIATION /11Z SATURDAY THROUGH WEDNESDAY/
THROUGH 12Z/SUN...VFR CONDITIONS WILL CONTINUE INTO THE MORNING
HOURS TODAY, THEN AN APPROACHING DISTURBANCE WILL BRING LOWERING
CIGS AND SOME SNOW SHOWERS BETWEEN 16-21Z/SAT, MAINLY TO
KGFL/KALB/KPSF, WHERE SOME MVFR CIGS AND/OR VSBYS COULD OCCUR.
BRIEF IFR VSBYS ARE POSSIBLE AT KGFL. MAINTAINED PROB30 GROUPS
WITH THIS UPDATE. MIXED VFR/MVFR CIGS ARE THEN EXPECTED AFTER
21Z/SAT WITH THE HIGHER CONFIDENCE FOR MVFR CIGS AT KPOU/KPSF
AS THIS DISTURBANCE BRINGS A PERIOD OF SNOW TO THESE SITES
BEGINNING 02-04Z/SUN. IF SNOW BECOMES STEADY ENOUGH, VSBYS
COULD LOWER TO IFR AT KPOU/KPSF AS WELL. THE NORTHERN EDGE OF
THE PRECIPITATION COULD BE NEAR KALB, BUT KEPT THIS TAF DRY FOR
NOW. WIND WILL BECOME SOUTH TO SOUTHWESTERLY AT 5-10 KT
TODAY WITH A FEW GUSTS TO 20 KT, MAINLY AT KALB/KPSF. WIND WILL
THEN BECOME WEST TO SOUTHWESTERLY AT 5-10 KT AFTER 00Z/SUN.
