333 FXUS61 KBGM 151924 AFDBGM Area Forecast Discussion National Weather Service Binghamton NY 224 PM EST Sat Nov 15 2025 .SYNOPSIS... A cold frontal boundary will move through the region tonight bringing a round of rain showers. Colder air will move into the region Sunday and Monday with some lake effect snow showers. Weak low pressure slides to our south Tuesday night with high pressure building in for the middle of next week. && .NEAR TERM /THROUGH SUNDAY NIGHT/... Low pressure will track through northern New England tonight. Enough lift and moisture will lead to the development of fairly widespread showers by evening. A slight amount of elevated instability is showing up on modeled soundings as well which is already resulting in a thunderstorm or two across the Finger Lakes. The potential for thunder should extend further east early this evening. Temperatures should stay steady through most of the night. The cold front pushes through Sunday morning. Cold air advection will start up with west-northwest flow off of Lake Ontario. This should promote the development of rain and snow showers in the afternoon that change to snow showers. Model soundings once again have an inverted V look showing the potential for some strong 30-40 mph wind gusts during the afternoon hours as well. A heavier snow shower with the wind could reduce visibility quite a bit, so a snow squall or two can`t be ruled out after sunset. Impacts of any snow accumulations should hold off for the most part till the evening hours when some slick spots could form. Given the slight amount of instability showing up it may be tough for the snow showers to organize into bands off of Lake Ontario. That and some changes with wind direction will lead to some variability with the locations of the lake effect snow keeping maximum totals fairly light at any one location. Temperatures should fall into the 20`s. && .SHORT TERM /MONDAY THROUGH MONDAY NIGHT/... Broken lake effect snow showers/ bands should continue through Monday night. Temperatures warming to near and above freezing may reduce snow ratios closer to 10:1 compared to the typical 15:1 with lake effect. Additional light accumulations should occur in spots that see more persistent snow showers. Total snow accumulations may creep into the 4-6 range for a few spots in Madison, Onondaga and Cayuga county. However, these totals will be over a 36 hour plus window. With that in mind, did not issue a headline for snow at this time. Temperatures generally in the 20`s and 30`s. && .LONG TERM /TUESDAY THROUGH SATURDAY/... Lake effect snow showers should decrease early Tuesday as high pressure builds into the region. A fairly notable northward trend has occurred with a weak area of low pressure passing to our south Tuesday night. A fair cluster of ensemble and operational models now bring measurable precipitation into NE PA Tuesday night. With temperatures falling below freezing some light snow accumulation could occur if the northward trend continues. Daytime temperatures though should warm well into the 30`s and 40`s through Thursday. High pressure should lead to a fairly quiet Wednesday and Thursday. Warm air advection behind the high pressure should result in a gradual warning trend late this week. NBM guidance is likely to fast bringing in showers Thursday, so lowered pops and raised temperatures based off of the southerly flow pattern. Rainfall from the next system should move in Friday. && .AVIATION /18Z SATURDAY THROUGH THURSDAY/... While conditions are VFR at the start of the TAF period, ceilings will gradually lower to MVFR to Fuel Alternate as the rest of the afternoon progresses as rain showers move into the area. There is also a low chance for thunder, but confidence is not high enough to include in the TAFs at this time. MVFR to Fuel Alternate restrictions are expected to continue through most of the remainder of the TAF period (at least through 18Z Sunday), although it is possible that KAVP and KELM return to VFR by mid-morning Sunday. There is chance for some IFR ceiling restrictions this evening as well, mainly at KBGM, KSYR, and KRME. Southerly winds at 10-15 kts are expected this afternoon before winds start gusting up to 20kts overnight tonight and then up to 30kts by Sunday afternoon. LLWS is also expected for a brief window this evening. Outlook... Sunday afternoon...Rain and snow showers, transitioning to all snow showers. Restrictions expected in any steadier snow showers. Monday...Scattered rain/snow showers possible along with associated restrictions. Tuesday...Lingering lake effect rain/snow showers with restrictions still possible; especially CNY terminals. Wednesday through Thursday...Mainly VFR. && .BGM WATCHES/WARNINGS/ADVISORIES... PA...None. NY...None. && $$ SYNOPSIS...MWG NEAR TERM...MWG SHORT TERM...MWG LONG TERM...MWG AVIATION...BJG
