880 FXUS61 KBGM 131825 AFDBGM Area Forecast Discussion National Weather Service Binghamton NY Issued by National Weather Service State College PA 125 PM EST Thu Nov 13 2025 .SYNOPSIS... Lake effect precipitation for the Finger Lakes into Central NY today through Friday morning. High pressure builds into the region Friday into Saturday before rain moves back in Saturday night into Sunday. Lake effect snow will be possible once again early next week. && .NEAR TERM /THROUGH TONIGHT/... Lake effect precipitation continues today and will persist into tomorrow. Abundant moisture will be available as flow is conducive to a multi lake connection. The difference will be the warmer temperatures today that will produce mostly rain today and limit any snow to the higher elevations. Colder air moves in at 850 mb later tonight and some accumulation will be possible at higher elevations with 2 to 4 inches not out of the question from today through tomorrow, but valley locations will likely only see some wet flakes overnight tonight, with very light if any accumulations. The lake effect snow looks to wind down tomorrow morning as ridging builds in and a subsidence inversion lowers, however, lingering lake effect clouds and a few flurries will be possible across central NY into the early afternoon. && .SHORT TERM /FRIDAY THROUGH FRIDAY NIGHT/... Ridging builds in Friday night and through most of the day on Saturday. A low develops and moves across Southern Canada Saturday night into Sunday morning as lifts a warm front across the region. Temperatures have trended warmer as the high pressure in New England has trended weaker, and any cold air damming likely stays off to our north and east, but will continue to watch how this unfolds with the next few model runs. If cold air can hang around, then there would be potential for a light icing of freezing rain on the Tug Hill and Mohawk Valley area. Precipitable water values get above climatology ahead of the low so rainfall will be more widespread and beneficial rather than showery like recent precipitation events. && .LONG TERM /SATURDAY THROUGH WEDNESDAY/... Low pressure tracks into northern New England Sunday morning and drags a cold front through our region. Lake effect precipitation develops again with the cold air advection on the back side of the front. Ensemble mean 850 temperatures fall below -6C Sunday into Sunday night, so all snow is looking more and more likely Sunday afternoon through Monday. Band organization or duration is uncertain this far out, but snow accumulations is likely somewhere downwind of Lake Ontario and winter weather headlines may be needed at a later time. The long wave trough will likely remain in place through at least Monday and then push east of the Northeast U.S. Tuesday and Wednesday. Flow mid to late week would then turn zonal, so shortwaves and low pressure systems will be much more progressive towards the end of next week, making any details in the forecast very uncertain at this time. There is also a great amount of spread with temperatures as models and ensembles vary greatly with the intensity and track of low pressure systems that move through the central US. If the low track next week is to our west and into the Great Lakes, we would expect warm temperatures for our region and possibly widespread rainfall. Still a lot to sort out and by the start of next week, models should have a better idea on how the pattern will pan out. && .AVIATION /18Z THURSDAY THROUGH TUESDAY/... Steady state Nwrly flow will continue through much of Friday and likely into Friday night with lake effect rain showers at lower elevations (and higher terrain rain/snow or snow showers across CNY today into early tonight). The mean boundary layer flow will veer from about 295 deg to 310 later tonight and Friday, which should help break the upstream connection of moisture off Georgian Bay and decrease areal coverage of the Lake Effect precipitation overnight tonight and Friday. Expect mainly MVFR Cigs and VFR vsbys for the bulk of the period at most or all airfields with brief IFR accompanying lake effect rain/show showers. The lake effect showers will continue to drift just south of RME late today through the middle of tonight, bringing a trend toward mainly VFR conditions there. There will be periods (20-30 percent of the time) when MVFR conditions impact the airfield. SYR should also see rain showers through the day and through the first half of the overnight hours, with MVFR/Fuel Alt conditions likely developing once again late tonight through Fri morning. The NWrly wind should bring more rain showers to ITH and BGM during the afternoon/evening hours with MVFR and Fuel Alt conditions lasting into the overnight hours. AVP and ELM should remain VFR through the day with brief periods of MVFR possible overnight/Friday . Outlook... Friday...Occasional restrictions possible in scattered rain and snow showers, especially at the Central NY terminals. Saturday...Mainly VFR. Sunday...Rain showers possible along with associated restrictions. Monday...Scattered rain/snow showers possible along with associated restrictions. && .BGM WATCHES/WARNINGS/ADVISORIES... PA...None.
