818 FXUS61 KBGM 221707 AFDBGM Area Forecast Discussion National Weather Service Binghamton NY 1207 PM EST Sat Nov 22 2025 .SYNOPSIS... Several weak frontal disturbances will keep our weather unsettled through the weekend, with chances for rain and wet snow showers at times. There will be plenty of clouds around this weekend, with near average temperatures. High pressure returns, bringing seasonably mild weather and more sunshine for Monday. The next weather system arrives later on Tuesday into Wednesday bringing periods of rain and warmer temperatures. && .NEAR TERM /THROUGH SUNDAY NIGHT/... A weak wave of low pressure is passing by to our south across the Mid-Atlantic early this morning. This will spread a period of steady, light to moderate rain across NE PA and the NY Southern Tier through daybreak; perhaps lingering until mid-morning in NE PA. Rainfall amounts will be up to a quarter inch in NE PA, fading to less than a tenth of an inch for the southern tier...and none further north in Central NY. After this wave of low pressure and rain shield moves away, our area will be under a modest cold air advection, NW flow regime the rest of today. 850mb temperatures fall to -5C this afternoon...which will allow lake effect/upslope stratus clouds to lingering much of the day; there could be a few occasional breaks in the overcast...and some partial clearing is expected by mid to late afternoon for the Wyoming Valley region of NE PA. Cooler with highs in the 40s areawide today. Tonight features partly cloudy skies, becoming mostly cloudy late; otherwise dry and seasonably chilly with lows down into the 20s. The clipper system is trending a bit stronger and further south for Sunday. This will mean mainly cloudy skies along with scattered snow and rain showers in the morning, with PoPs increasing to likely by the afternoon and early evening across Central NY. With 850mb temperatures aloft warming to around -2 or -3C during the day, surface temperatures should rise into the 40s for daytime highs. These mild temperatures should prevent any snow accumulation during the daytime hours. With that said there is a slight chance for a light dusting or coating of snow before about 9/10 AM if the snow shower activity arrives fast enough, as surface temperatures will still be near or below freezing until this time. Precipitation amounts are forecast to be light; less than a tenth of an inch on Sunday. Slightly breezy southwest winds turn west-northwest late in the day, between 8-15 mph. && .SHORT TERM /MONDAY THROUGH TUESDAY NIGHT/... Behind the cold front winds shift northwesterly and 850mb temps fall to around -6 to -8C Sunday night. This will be just cold enough to start up a minor lake effect response off of Lake Ontario and perhaps the Finger Lakes. Have high chance to likely PoPs for the first half of the overnight period, fading to chance or slight chance late at night into early Monday morning as high pressure approaches. Once again, precipitation amounts are expected to be rather light; under a tenth of an inch. The rain showers eventually mix over to mostly lingering snow showers as it cools down into the upper 20s to mid-30s overnight. High pressure moves over the region of Monday, bringing decreasing clouds and seasonable temperatures. It looks to stay dry Monday night with increasing mid and high level clouds ahead of the next, incoming weather system. Tuesday morning could end up dry, before rain moves in later in the day. Seasonable temperatures continue with highs in the 40s. Periods of rain/showers lingering Tuesday night...with very mild overnight low temperatures holding in the upper 30s to mid-40s out there. && .LONG TERM /WEDNESDAY THROUGH FRIDAY/... This period starts off rather warm on Wednesday, with a deep southwesterly flow and warm air advection over the forecast area. It will still be mainly cloudy with chances for showers as the cold front approaches from the west later in the day or overnight. Thanksgiving Day is trending colder, with 850mb temperatures potentially hovering around -8C through the day. Expect mostly cloudy and breezy conditions on Thanksgiving with a chance for lake effect snow or lower elevation rain showers. Westerly winds gusts up to around 25 mph and daytime highs only reach the upper 30s to mid- 40s. Cold air advection continues to strengthen over the area Friday into Saturday with 850mb temps hovering between about -10C to -12C in this timeframe. There is high chance to low end likely PoPs for lake effect snow showers over the area. Exact details such as lake effect orientation, amounts and extent remain uncertain this far out in time. Otherwise it will be partly to mostly cloudy, breezy and seasonably cold out there for the end of the upcoming workweek and into next weekend. && .AVIATION /18Z SATURDAY THROUGH THURSDAY/... VFR conditions expected at all terminals through the 18Z TAF period. Gusty winds for some terminals will decrease in the late afternoon hours. Outlook... Sunday...Scattered rain/snow showers and associated restrictions possible. Monday...Mainly VFR. Tuesday into Thursday...Chance for rain showers and associated restrictions. && .BGM WATCHES/WARNINGS/ADVISORIES... PA...None.
