AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BINGHAMTON NY
737 PM EDT WED OCT 29 2025
SYNOPSIS
RAIN MOVES INTO THE REGION TONIGHT AS LOW PRESSURE APPROACHES
FROM THE SOUTH. WIDESPREAD SOAKING RAIN IS EXPECTED ON
THURSDAY. LOW PRESSURE EXITS TO THE NORTH ON FRIDAY, BUT
UNSETTLED WEATHER WILL CONTINUE WITH GUSTY WINDS AND SCATTERED
RAIN SHOWERS. A COOL NORTHWEST FLOW PATTERN THEN PERSISTS
THROUGH THE WEEKEND, WITH SCATTERED LAKE EFFECT SHOWERS.
NEAR TERM /THROUGH THURSDAY NIGHT/
RAIN PUSHES INTO THE REGION FROM THE SOUTH LATE TONIGHT AND
EARLY THURSDAY MORNING. SURFACE LOW PRESSURE TRACKS ACROSS
CENTRAL NY ON THURSDAY WITH A WIDESPREAD SOAKING RAINFALL
EXPECTED. DRY ANTECEDENT CONDITIONS IN PLACE TAKES AWAY ANY
FLOODING CONCERNS WITH THIS HEAVY RAINFALL, HOWEVER, LOCALIZED
URBAN FLOODING ISSUES COULD ARISE DUE TO CLOGGED DRAINS AND
CULVERTS FROM LEAF DEBRIS. ALONG WITH THE RAIN ON THURSDAY,
SUSTAINED EASTERLY WINDS OF 10-15MPH GUSTING TO 25 MPH PICK UP
IN THE MORNING AND LAST INTO THE EVENING. WINDS WILL LIGHTEN UP
AS THE CENTER OF THE LOW MOVES OVERHEAD THURSDAY NIGHT.
MUCH NEEDED RAIN WILL FALL ACROSS THE AREA, WITH THE 1-2 INCHES
OF RAIN IS EXPECTED FROM THE FINGER LAKES THROUGH THE SOUTHERN
TIER AND INTO THE SOUTHERN CATSKILLS. FARTHER NORTH, 0.75-1 INCH
OF RAIN IS EXPECTED INTO THURSDAY EVENING.
SHORT TERM /FRIDAY THROUGH SATURDAY NIGHT/
LOW PRESSURE MOVES OFF TO THE NE ON FRIDAY. BY FRIDAY MORNING
WE WILL BE IN THE SW QUADRANT OF THE LOW WHICH WILL INTRODUCE A
WIND DIRECTION CHANGE AND WE WILL SEE WINDS SHIFT FROM EASTERLY
TO WNW. TO GO ALONG WITH THIS SHIFT, THE PRESSURE GRADIENT
TIGHTENS AND WIND SPEEDS WILL INCREASE. STRONG WINDS ARE EXPECTED
FRIDAY INTO EARLY SATURDAY MORNING. GUSTS UP TO 45 MPH WILL BE
POSSIBLE, ESPECIALLY ACROSS THE HIGHER TERRAIN. WINDS REMAIN
GUSTY OVERNIGHT INTO SATURDAY MORNING, WITH GUSTS OF 35 TO 40 MPH
POSSIBLE. WE WILL KEEP A CLOSE EYE ON HOW THE LOW PRESSURE
CENTER DEVELOPS AND TRACKS. IF THE LOW DEEPENS A LITTLE MORE
THAN CURRENTLY FORECAST, WINDS WILL BE STRONGER AND A WIND
ADVISORY MAY BE NEEDED FOR PARTS OF THE AREA ON FRIDAY INTO
FRIDAY NIGHT.
A COLD FRONT WILL PUSH THROUGH THE AREA ON FRIDAY MORNING.
COOL NW FLOW WILL SET UP AND REMAIN THROUGH MUCH OF THE WEEKEND.
RAIN SHOWERS CONTINUE ON FRIDAY AS WRAP AROUND PRECIP FROM THE
DEPARTING LOW WILL BE ENHANCED BY COLD AIR MOVING ACROSS THE
GREAT LAKES. THIS PRECIP WILL SWITCH TO ALL LAKE EFFECT BY
SATURDAY MORNING, WITH THE FINGER LAKES INTO THE MOHAWK VALLEY
SEEING SCATTERED RAIN SHOWERS. THESE LAKE EFFECT SHOWERS WILL
LAST THROUGH SATURDAY NIGHT. TEMPS SATURDAY NIGHT WILL BE IN THE
MID TO UPPER 30S FOR MOST, WITH LOW 40S IN THE WYOMING VALLEY
AND NORTHERN FINGER LAKES AND LOW 30S ACROSS NORTHERN ONEIDA
COUNTY AND CAN'T RULE OUT A FEW SNOW FLAKES SATURDAY NIGHT.
THE TRICK OR TREAT FORECAST LOOKS PRETTY GLOOMY FOR THOSE
PLANNING ON PARTAKING IN THE FESTIVITIES. STRONG WINDS WILL
CAUSE WIND CHILLS TO BE IN THE MID 30S ACROSS MUCH OF THE AREA,
WITH SCATTERED RAIN SHOWERS ALONG AND NORTH OF THE SOUTHERN
TIER.
LONG TERM /SUNDAY THROUGH WEDNESDAY/
THERE REMAINS A LOT OF UNCERTAINTY THROUGH THE LONG TERM PERIOD.
ALTHOUGH HIGH PRESSURE BUILDS INTO THE REGION ON SUNDAY, COOL
WESTERLY FLOW MAY CONTINUE TO KICK OFF LAKE EFFECT SHOWERS. MODEL
SOLUTIONS ARE EXTREMELY VARIED ENTERING THE BEGINNING OF NEXT
WEEK AS THEY ARE HAVING A HARD TIME RESOLVING THE EVOLUTION OF
ANOTHER DEEP TROUGH DIGGING INTO THE SOUTHERN MISSISSIPPI
VALLEY ON SUNDAY. SOME GUIDANCE DIGS IT DEEP INTO THE GULF COAST
AND CUTS IT OFF FROM THE FLOW, WHILE OTHERS DIG IT TO THE SE US
AND PUSHES IT OFF SHORE, AND STILL OTHERS KEEP IT MUCH WEAKER
AND PROGRESSIVE, PUSHING IT THROUGH THE SE AND INTO THE ATLANTIC
WITHOUT DEVELOPING ANYTHING.
WHILE THIS FEATURE IS DEVELOPING, ANOTHER SHORTWAVE IS PROGGED
TO MOVE INTO THE GREAT LAKES ON MONDAY INTO TUESDAY. THIS
SHORTWAVE COULD BRING LIGHT RAIN SHOWERS TO THE AREA OR, IF IT
IS ABLE TO PHASE WITH THE DEEP LOW OVER THE SE US, WE COULD SEE
ANOTHER SOAKING RAIN EVENT. THERE IS WAY TOO MUCH UNCERTAINTY TO
SAY WITH ANY SKILL WHICH WAY THE FORECAST WILL TREND. BECAUSE
OF THIS, NBM GUIDANCE WAS USED WHICH BRINGS SHOWERS ACROSS THE
AREA MONDAY THROUGH WEDNESDAY.
AVIATION /00Z THURSDAY THROUGH MONDAY/
VFR CONDITIONS CONTINUE THROUGH THE LATE EVENING HOURS. A
SYSTEM WILL MOVE INTO THE REGION FROM THE SOUTH LATE TONIGHT.
CEILINGS WILL GO FROM MVFR TO IFR WITH AVP SEEING RESTRICTIONS
FIRST BY 06Z. IN ADDITION TO THE CEILING RESTRICTIONS, STEADY
RAIN SHOWS WILL REDUCE VISIBILITIES SOME. THE RAIN AND
ASSOCIATED RESTRICTIONS CONTINUE THROUGH AT LEAST 00Z FRIDAY.
WHILE EAST-NORTHEAST WINDS ARE CURRENTLY LIGHT, THEY WILL
GRADUALLY BECOME MORE BREEZY. WINDS PICK UP TO 10 TO 15 KTS WITH
GUSTS UP TO 25 KTS. LOW-LEVEL WIND SHEAR IS ALSO POSSIBLE AT
AVP, BGM AND ITH AFTER 12Z. WINDS AT 2000 FT AGL WILL BE
EASTERLY AT 40 TO 50 KTS.
