801 FXUS61 KALY 070137 AFDALY AREA FORECAST DISCUSSION National Weather Service Albany NY 837 PM EST Sat Dec 6 2025 .UPDATE... As of 8:35 PM EST...Quick update was needed as most of the area is seeing widespread low to mid-level clouds, which is resulting in temperatures running several degrees above the previous forecast for many areas. Temperatures are currently in the mid 20s to low 30s for most areas. Current GOES 16 nighttime microphysics RGB satellite product shows widespread cloud cover upstream, so it is unlikely that these clouds will dissipate any time soon. We therefore bumped up temps through the next several hours. Will see how things trend over the next several hours, but temps may even need to be increased a couple degrees more, especially late tonight. There are more breaks of clearing across southern Dutchess and Litchfield Counties, and may therefore cool off quicker than across the rest of the region. Otherwise, previous forecast remains on track with more details below... && .SYNOPSIS... Aside from some passing light snow showers and flurries for western areas this evening, mainly dry and chilly weather is expected for tonight into Sunday morning. A fast moving wave of low pressure will bring a period of light snow for Sunday night, mainly for the Adirondacks. Behind this system, cold and blustery conditions are expected on Monday, which will be followed for unsettled weather through much of the upcoming week. && .SHORT TERM /THROUGH MONDAY NIGHT/... Key Message: - Fast moving low pressure will bring a period of accumulating snow on Sunday evening into Sunday Night. NBM probabilities for seeing 1" or snow or greater are 50% or higher for the western and central Adirondacks and far western Mohawk Valley. Discussion: Through this evening, there may be some scattered snow showers for far western areas, but any accumulation will be just a coating or less and mainly just limited to the far northwestern Adirondacks. Otherwise, the moisture-starved cold front will pass through the region, allowing for temperatures to fall into the teens and 20s for lows tonight. Skies will start out partly sunny on Sunday, but increasing clouds are expected by later in the day, as the next wave of low pressure approaches from the west. This will be a weak storm over the Midwest that will be moving towards the area, although the track of storm (basically right across Upstate New York) will keep the best moisture and forcing mainly north of the region over the North Country and Quebec. As a result, QPF will be rather limited across our area, with the better snow accumulation north of the region. Some light snow may develop by the late afternoon or early evening hours for western areas and will track eastward for the overnight. Most of the activity should be done across our area by 1 or 2 AM based off the latest CAMS and NBM guidance. NBM probabilities have decreased over the past few days, with the only areas over 50% for 1" over the western Adirondacks. Albany only has a 4% chance of 1", with even just a coating now down to 25%, as snowfall may be limited by downsloping, limited QPF and dry low-levels. While some locally slippery spots are possible over the Adirondacks, most areas won`t be seeing any impacts from this light snowfall with this fast moving clipper system. As it departs, colder air will pour into the region, allowing temps to fall into the single digits and teens, with breezy conditions developing by Monday morning. It will be a cold and blustery day on Monday. Despite a mostly sunny sky, temps will only reach the teens and 20s for highs with northwest winds gusting up to 25 mph. Winds chill will be in the single digits at times, especially for the higher terrain. As the high pressure area moves overhead for Monday night, winds will decrease and temps will fall near zero for much of the area for overnight lows, making for another early season frigid night. && .LONG TERM /TUESDAY THROUGH SATURDAY/... With a fast northern stream in place, there will be a few opportunities for unsettled wintry weather through the long term period. On Tuesday, it will be continued chilly with highs still only in the 20s. As the high pressure departs off to the east, southerly winds will increase and clouds will also be increasing ahead of the next storm system, which will be another northern stream clipper system. As with the past one, this will be fairly moisture starved and generally tracking north of the area. Aside from some passing light snow showers (mainly for northern areas) on Tuesday evening, this will generally pass through without much impact. The next system looks to have more of an impact, as a stronger low pressure system will be moving through the Great Lakes for Wednesday. This stronger system will have more moisture associated with it and looks to impact the region from late Tuesday night through Wednesday and into Wednesday evening. While most areas should see some snow initially, the southerly flow ahead of this system will allow for milder air to move in at low levels and aloft as well. Valley areas will likely see a changeover to rain, although there is still uncertainty regarding the exact track and QPF. NBM suggests many areas may see a light accumulation before a changeover occurs as well, with at least a 40% chance for a coating across the entire area and high terrain areas seeing at least a 50% chance for 1" or more. Despite the possibility of rain, surface temps will still be chilly and may just be warm enough (mid to upper 30s) in valley areas for rainfall. Behind this system, more cold air will return for the late week. Models suggest another storm system could impact the region by late Thursday or Friday, although guidance has a lot of variability with the potential storm track. With colder air in place, p-type would most likely be snow, but QPF will depend on exact storm track. The potential for more accumulating snow is there, but this will come into better focus by early next week. Overall, temps for the late week will continue to average below normal levels. && .AVIATION /02Z SUNDAY THROUGH THURSDAY/... Through 00z Monday...VFR conditions as of 6:20 PM EST at all terminals, although skies are becoming BKN to OVC with cigs 3500- 4500 ft. For GFL/POU/ALB, these low-end VFR cigs with BKN to OVC cigs 3500-4500 ft are expected to continue through early tomorrow morning. A brief period of MVFR cigs can`t be ruled out at ALB for a few hours around sunrise. At PSF, cigs trend down from VFR to MVFR within the first few hours of the TAF period, and to MVFR fuel alternate cigs after 06z. Low confidence on if cigs get down to IFR levels at PSF later tonight into tomorrow morning, but based on latest guidance have added a tempo groups to highlight the most likely timeframe of possible IFR conditions. All terminals see improvement by mid-morning, with BKN cigs 4000- 5000 ft at ALB/GFL/POU and cigs 2000-3000 ft at PSF. Conditions then deteriorate tomorrow afternoon and evening as another upper disturbance tracks by. Mainly MVFR cigs expected, except at POU where cigs remain VFR. Some snow showers are also possible after 21z, with the best chance at GFL followed by ALB. Here, have added prob30 groups to highlight that IFR vsbys are expected within snow showers. Winds will generally be at around 5 kt or less through most of the TAF period, except at PSF tonight where west winds will be at 4-8kt. Outlook... Sunday Night: Moderate Operational Impact.
