NWS Binghamton, NY wrote its last area forecast discussion before the first event at Feb 26, 5:40 PM EST, 50 minutes earlier.
Area Forecast Discussion National Weather Service Binghamton NY 540 PM EST Wed Feb 26 2025 .SYNOPSIS... A system moving through the area this evening through Thursday will bring periods of rain, snowfall, and a wintry mix with potential for some freezing rain for some areas in Central New York. This will be followed by another low pressure system this weekend bringing additional chances for rain and snow. High pressure builds into the region for the first part of next week. && .NEAR TERM /THROUGH THURSDAY NIGHT/... 535 PM Update... There are some returns on radar though conditions are currently too dry for rain to reach the ground. Temperatures remain in mid 30s to mid 40s at this time. With cloud cover over most of the region, the cooling of temps was slowed down slightly through the evening hours. This then resulted in more rain expected for the main precipitation type later this evening. These were minor changes as the previous forecast was doing well. 235 PM Update... With temperatures that have proven guidance to be under-performing, precipitation types will more likely stay on the side of rainfall and a wintry mix, rather than as snowfall. Overall snowfall totals through Thursday have lowered, with areas east of I-81 barely pushing a half inch. Precipitation will start as rainfall, pushing southwest to northeast, and transitioning to a wintry mix as it spreads over Central NY and NE PA after 10 PM. The most difficult aspect of the overnight forecast will be any chances for freezing rain to occur. The 850 0C line surges northward, and there will be a period in the overnight hours where the chances for freezing rain increases for a couple of hours, mainly for northern portions of Central NY. There would most likely only be up to a glaze of accumulation, which will also likely wash away Thursday morning as precipitation transitions back to rainfall with temperatures increasing. Going into Thursday, our area will be in the deep warm sector of this system, and temperatures will surge into the mid 40s to low 50s, with rain showers continuing for most of the day. Rainfall intensity will decrease through the day, with areas ending a quarter to a half inch of overall precipitation, which includes any rainfall and snowfall an area may receive. This system passes us later in the day Thursday, and flow switches westerly. Colder air will begin to filter in that evening, and lingering precipitation will transition back to a wintry mix briefly, before temperatures fall below freezing overnight and precipitation transitions back to snow. Lingering snowfall is most likely over the northern portions of Central NY Thursday night as westerly flow coaxes lake enhancement to occur, and these areas could see a half inch of snowfall overnight Thursday. && .SHORT TERM /FRIDAY THROUGH SATURDAY NIGHT/... 245 PM Update Fairly active weather period with a strong clipper system, strong cold front, chance for snow squalls and lake effect snow showers. After a brief warm up early Saturday, much colder temperatures return by Saturday night. There will be some lingering lake effect snow showers Friday morning in the cold west-northwest flow with 850mb temperatures around -13C, but QPF and snow amounts look light. High pressure briefly builds in late Friday morning through the afternoon hours, with a short period of dry weather. It will be cold with highs in the upper 20s to 30s...except some lower 40s for the Chemung and Wyoming Valleys. By late Friday afternoon or evening snow, mixed with rain in the valleys will overspread Central NY and the northern tier of NE PA out ahead the next, potent clipper system. The low pressure system will pass just north of most of the CWA; except perhaps northern Oneida county. This will mean fairly strong warm advection overnight into Saturday morning as the southerly flow develops ahead of it. Therefore temperatures should rise overnight through the 30s. The initial snow will mix with or change over to rain for most of the area, except along and north of I-90 in Oneida county, where it remains below freezing at the surface and aloft (-3C at 850mb) through the night and into Saturday morning. AT this point in time, most of CNY is expected to see 1 inch or less of snowfall Friday night into Saturday morning, with little to no accumulation in NE PA. The exception will be Oneida County, where Utica to Rome is forecast to see 1-2 inches of wet snow and northern Oneida county could be in for 2 to 5 inches of snow. There is still uncertainty in just how mild it will get Saturday morning and early afternoon out ahead of the cold front. Kept the official forecast close to the NBM, which usually does well in these brief warm sector situations. Forecast highs are expected to reach the mid-30s to mid-40s over the area, and even some upper 40s for the Wyoming Valley and Delaware river Valley locations of NE PA. A sharp, strong cold front then moves through the area from west to east Saturday afternoon. Along this cold front there will be snow showers and even a chance for scattered snow squalls due to steep low level lapse rates, modest instability (100 J/kg MUCAPE 0-2km layer) and sharp pressure rises. Boundary layer and surface temperatures will ultimately play a big role on how impactful these snow showers and squalls may be Saturday afternoon into the evening. Eventually, as cold air advection increases the precipitation will transition to lake effect snow showers Saturday evening and overnight. We are expecting a fairly good lake effect response, as parameters look favorable for multibands and showers in a 300-330 degree flow. Eventually the deeper 700mb moisture looks to exit the area late at night, which should decrease the intensity and coverage. At this time, additional accumulations are expected to be on the lighter side, generally a dusting to 2 inches across CNY. It turns blustery and much colder Saturday night with NW winds 10-20 mph gusting up to 30mph. Overnight lows dip down into the single digits to mid-teens for most locations. && .LONG TERM /SUNDAY THROUGH WEDNESDAY/... 255 PM Update This period starts off with generally quiet but a much colder weather pattern to round out the weekend and into early next week. Some lingering lake effect snow showers or flurries will be around for the favored CNY locations Sunday, Sunday night and even Monday morning. Otherwise, it is looking dry and partly cloudy across the rest of the region. Sunday is very cold, some 15 degrees below average, with highs only forecast to reach the 10s to mid-20s for CNY...with upper 10s to upper 20s in NE PA. Very cold Sunday night with lows potentially below zero in the colder spots of Oneida county, single digits to lower 10s elsewhere. A surface high pressure system builds into the area on Monday which may allow for more sunshine away from the lake effect zones. Temperatures begin to moderate, but still slightly below average. It is forecast to turn much milder, back into the 40s for Tuesday and at this time it likely to remain dry. The next potentially stronger weather system approaches the area from the midwest heading into the middle of next week. Current data suggests periods of rain, winds and much warmer temperatures as the strong low passed west of us into the central Great Lakes region. && .AVIATION /00Z THURSDAY THROUGH MONDAY/... VFR conditions across all terminals will continue until the overnight hours. A few terminals have some gusty northwesterly winds which will taper off in the next few hours. A system bringing rain and a mix of rain and snow will move through, impacting terminals SW to NE starting between 03Z and 07Z. The biggest forecast challenge is the lowest category some terminals will fall too. Confidence for IFR conditions after 04Z for BGM, ITH, and ELM is moderate, while SYR and RME, confidence remains low, and we chose to leave it out of the 18Z TAF package. This may be added to the 00Z package, if guidance continues supporting it. Fuel Alt/IFR conditions continue for all terminals for the majority of the 18Z TAF period. Confidence was too low to provide a timing for conditions to improve, but will likely be sometime after 15Z. Outlook... Thursday...Chance for daytime rain showers that change to snow showers overnight and associated restrictions (moderate confidence) Friday...Scattered snow showers and associated restriction, mainly at CNY terminals (moderate to high confidence) Saturday... Scattered daytime rain showers that become snow showers overnight, restrictions possible. Sunday...Chance for lake effect snow showers/ Finger Lake snow showers at KSYR, KRME, KITH and KBGM with restrictions. Monday...Mainly VFR. && .BGM WATCHES/WARNINGS/ADVISORIES... PA...None.
