AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BINGHAMTON NY
710 PM EST SUN DEC 7 2025
SYNOPSIS
A WEAK SYSTEM WILL PUSH THROUGH THE REGION TODAY WITH LIGHT SNOW
EXPECTED ACROSS CENTRAL NEW YORK. THE WEATHER PATTERN WILL
REMAIN ACTIVE, WITH SEVERAL CLIPPER SYSTEMS BRINGING CHANCES FOR
LIGHT SNOW OVER THE NEXT WEEK.
NEAR TERM /THROUGH MONDAY NIGHT/
FORECAST REMAINS ON TRACK THROUGH THE PERIOD. A WEAK SHORTWAVE
IS MOVING ACROSS THE AREA, KICKING OFF SCATTERED SNOW SHOWERS TO
OUR WEST THAT ARE SLOWLY MOVING INTO THE CWA. SHOWERS ARE
EXPECTED TO INCREASE THIS AFTERNOON, ESPECIALLY ACROSS AREAS
NORTH OF THE SOUTHERN TIER. A COLD FRONT WILL PUSH THROUGH LATE
THIS AFTERNOON/EARLY EVENING WHICH WILL SHIFT WINDS TO THE WNW
AND KICK OFF LAKE EFFECT SNOW SHOWERS, FIRST MOVING THROUGH THE
MOHAWK VALLEY AREA, THEN SLIDING INTO THE FINGER LAKES REGION
TONIGHT AS THE WINDS BECOME MORE NWERLY. LIGHT SNOW SHOWERS ARE
EXPECTED TO STICK AROUND INTO THE EARLY MORNING HOURS BEFORE
HIGH PRESSURE BUILDS IN FROM THE WEST AND ENDS THE PRECIP. SNOW
AMOUNTS TODAY AND TONIGHT WILL BE LIGHT, WITH 1-2 INCHES
ENCOMPASSING AN AREA FROM CAYUGA TO CORTLAND TO ONEIDA COUNTY.
LOCALIZED AMOUNTS APPROACHING 3 INCHES WILL BE POSSIBLE ACROSS
HIGHER ELEVATIONS SOUTH OF THE MOHAWK VALLEY IF A FEW LAKE
EFFECT SHOWERS TRAIN OVER THE SAME AREA. A TRACE TO AN INCH WILL
BE POSSIBLE FOR THE REST OF THE AREA NORTH OF THE SOUTHERN
TIER.
BEHIND THE COLD FRONT, VERY COLD AIR WILL DROP LOWS TONIGHT
INTO THE SINGLE DIGITS NORTH OF THE SOUTHERN TIER AND LOW 10S
OVER AND SOUTH OF THE SOUTHERN TIER. HIGH PRESSURE BUILDING IN
FORM THE WEST ON MONDAY WILL REINFORCE THE COLD AIR ADVECTION
AND KEEP HIGHS ON MONDAY IN THE TEENS FOR MOST AND LOW 20S IN
THE VALLEYS OF NEPA. MONDAY NIGHT WILL BE THE COLDEST OF THE
WEEK AS THE CENTER OF THE SURFACE HIGH SITS RIGHT OVER THE AREA.
RADIATIONAL COOLING COMBINED WITH THE ALREADY COLD AIRMASS WILL
ALLOW TEMPS TO FALL INTO THE LOW SINGLE DIGITS FOR MOST, WITH
-0S ACROSS HIGHER ELEVATIONS EAST OF I-81. LUCKILY THE WINDS
WILL BE MOSTLY CALM BUT THEY ARE EXPECTED TO PICK UP A LITTLE
BIT BEFORE SUNRISE, WHICH WOULD PUSH WINDCHILLS TO 0 TO -9
ACROSS THE REGION.
SHORT TERM /TUESDAY THROUGH WEDNESDAY NIGHT/
HIGH PRESSURE MOVES EAST OF THE AREA TUESDAY MORNING AS THE NEXT
SET OF SHORTWAVES MOVE INTO THE GREAT LAKES AND UPPER MIDWEST.
WINDS WILL BECOME SOUTHERLY ON TUESDAY AND PUSH WARMER AIR INTO
THE REGION FROM THE SOUTH. STRONG SOUTHERLY WINDS OF 10-20MPH
WITH GUSTS UP TO 30MPH WILL PUSH TEMPS INTO THE MID 20S BY MID
AFTERNOON. A WEAK SHORTWAVE EXITING THE EASTERN GREAT LAKES
COMBINED WITH ISENTROPIC LIFT FROM THE WAA WILL KICK OFF
SCATTERED SNOW SHOWERS ACROSS THE AREA IN THE AFTERNOON AND
EVENING. SOME LAKE ENHANCED SHOWERS WILL STICK AROUND NORTH OF
THE SOUTHERN TIER INTO THE OVERNIGHT HOURS.
A MUCH STRONGER SHORTWAVE WILL BE RIGHT ON ITS TAIL, MOVING INTO
THE AREA ON WEDNESDAY. A SURFACE LOW WILL DEVELOP OVER THE GREAT
LAKES TUESDAY NIGHT AND THE CENTER OF THE LOW WILL TRACK NORTH
OF OUR CWA ACROSS ONTARIO ON WEDNESDAY. PRECIP WILL MOVE IN ON
WED MORNING AS SNOW, THEN CHANGE TO AN ELEVATION BASED
RAIN/SNOW MIX AS TEMPS CLIMB INTO THE MID TO UPPER 30S BY THE
AFTERNOON FOR MOST OF THE AREA. A CHANGE BACK TO ALL SNOW WILL
RETURN DURING THE EVENING AS A COLD FRONT MOVES THROUGH THE AREA
FROM THE NW. LAKE EFFECT SNOW SHOWERS WILL REMAIN DURING THE
OVERNIGHT HOURS ACROSS CNY.
NORTHERN ONEIDA COUNTY IS EXPECTED TO REMAIN COLD ENOUGH FOR
SNOW TO CONTINUE TO FALL THROUGH THE DAY ON WEDNESDAY, WITH
LAKE ENHANCED SHOWERS REMAINING THROUGH THE OVERNIGHT HOURS.
THE SW FLOW THAT IS EXPECTED TO BE DOMINANT THROUGH THE DAY WILL
PROVIDE UPSLOPE LIFT INTO THE AREA THAT WILL HELP ENHANCE
SNOWFALL CHANCES. CURRENTLY, 2-5 INCHES IS FORECAST TO FALL
OVER THIS AREA THROUGH WED EVENING, WITH MORE POSSIBLE DURING
THE OVERNIGHT HOURS. ENSEMBLE GUIDANCE IS SHOWING A 60-70% CHANCE FOR
GREATER THAN 4 INCHES OF SNOW ACROSS FAR NORTHERN ONEIDA COUNTY
DURING THIS PERIOD. WE WILL BE MONITORING HOW THIS DEVELOPS AS
A WINTER HEADLINE MAY BE NEEDED FOR THE AREA DURING THIS PERIOD.
HINDRANCES TO THIS WOULD BE WARMER AIR THAN CURRENTLY MODELED
MOVING INTO THE REGION, LIMITING SNOWFALL CHANCES, OR A
DIFFERENT TRACK TO THE LOW WHICH WOULD ALTER SNOW AMOUNTS ACROSS
THE REGION.
LONG TERM /THURSDAY THROUGH SUNDAY/
LAKE EFFECT SNOW SHOWERS SHOULD STICK AROUND THE AREA THURSDAY
WITH -12 TO -15C 850MB TEMPS FLOWING OVER LAKE ONTARIO. THE WIND
FIELD LOOKS TO VEER WITH HEIGHT, WHICH WOULD KEEP SHOWERS MORE
CELLULAR THAN BANDED ACROSS AREAS NORTH OF THE SOUTHERN TIER.
AFTER THURSDAY, GUIDANCE VARIES GREATLY AS TO HOW THE NEXT
SHORTWAVE WILL IMPACT THE REGION. WHAT LOOKED LIKE BETTER
CHANCES FOR IMPACTFUL SNOW YESTERDAY NOW PUSHES ANY LARGE LOW
PRESSURE SYSTEM EAST OF THE AREA AS THE TROUGH AND JET STREAM
DO NOT AMPLIFY UNTIL THEY ARE OVER THE ATLANTIC. WILL HAVE TO
CONTINUE TO MONITOR THE DEVELOPMENT OF THIS SYSTEM, BUT SNOW
SHOWERS ARE POSSIBLE FRIDAY NIGHT INTO SATURDAY, WHETHER IT BE
FROM A LOW PRESSURE SYSTEM OR A COMBO OF PASSING SHORTWAVE AND
LAKE EFFECT SNOW. NO MATTER HOW THIS PLAYS OUT, ARCTIC AIR IS
EXPECTED TO SPILL INTO THE AREA FROM THE NW SOMETIME SAT
AFTERNOON OR EVENING.
AVIATION /00Z MONDAY THROUGH FRIDAY/
A FRONT IS MOVING THROUGH THIS EVENING BRINGING A NARROW BAND OF
SNOW SHOWERS TO THE REGION. NY TERMINALS WILL LIKELY SEE IFR OR
NEAR IFR VIS WITH THE FRONTAL PASSAGE DUE TO THE SNOW WITH A
TEMPO ADDED AS THE RESTRICTIONS SHOULD BE LESS THAN AN HOUR. DRY
AIR AND WARMER TEMPERATURES AROUND AVP MAY HELP KEEP
RESTRICTIONS TO MVFR AT WORST SO NO IFR WAS INCLUDED IN THE TAF.
DRY AIR BEHIND THE FRONT SHOULD SCATTER OUT THE CLOUDS BY AROUND
6Z AT ALL TERMINALS BUT SYR AND RME WHERE LAKE EFFECT CLOUDS
AND SNOW CONTINUE TILL CLOSER TO 12Z. SOME UNCERTAINTY REMAINS
AT ITH AS WINDS LOOK FAVORABLE FOR SOME LAKE EFFECT SNOW SHOWERS
LATER AFTER 6Z BUT THE FETCH ACROSS LAKE ONTARIO IS LOW SO THE
SNOW SHOWERS MAY NOT MATERIALIZE. AN AMENDMENT WILL BE MADE IF
IT LOOKS LIKE SNOW IS DEVELOPING AS IFR RESTRICTIONS COULD
OCCUR LATER THAN FORECAST.
VFR CONDITIONS EXPECTED 12Z ONWARD WITH HIGH PRESSURE IN PLACE.
OUTLOOK...
MONDAY NIGHT...VFR EXPECTED.
TUESDAY...VFR IN THE MORNING TO EARLY AFTERNOON HOURS. THEN, RESTRICTIONS
POSSIBLE IN SCATTERED SNOW SHOWERS LATE AFTERNOON, EVENING AND
OVERNIGHT.

THURSDAY AND FRIDAY...RESTRICTIONS POSSIBLE WITH SNOW SHOWERS
POSSIBLE IN THE AREA.
