049 FXUS61 KBTV 061755 AFDBTV Area Forecast Discussion National Weather Service Burlington VT 1255 PM EST Sat Dec 6 2025 .SYNOPSIS... A few scattered snow showers will be possible today, mainly in the Adirondacks and northern Vermont, while a disorganized front crosses south. Some areas have popped above freezing today, but cool air will return tomorrow. A clipper system will bring a renewed chance of widespread light snowfall late Sunday and Sunday night. A coating to a few inches of is expected. Colder conditions return for Monday and Monday, while unsettled weather continues through much of next week. && .NEAR TERM /THROUGH SUNDAY NIGHT/... As of 1251 PM EST Saturday...A cold front will shift southeastwards tonight. Southwest flow is feeding some moisture off Lake Ontario, and will help produce a broken strip of snow showers with little in the way of accumulations outside areas farther out of Lake Ontario or north slopes. Even then, may just an inch in St. Lawrence County in NY or near spots like Jay Peak in VT. The cold front swings through with a reinforcing shot of cold air. It`ll take some time for temperatures to cool, but we`ll see steadier drops after 4 AM towards teens and single digits above zero. On Sunday, the boundary is going to stall, and then lift back north as a warm front along a Clipper type low. Despite struggling to fall below 1010mb, the dynamics associated with this system feature increasing FGEN and deformation, but nothing impressive in the upper level pattern or elevated lapse rates. Additionally, the best moisture moves out before the upper trough pivots through. The dendritic growth layer will be modestly large given the cool conditions. So there will be light snow, and ratios will probably approach 20:1, maybe even 25:1. With about 0.05-0.20" of QPF forecast, that should net anywhere between 1-4" of snow with localized amounts around 5" across the Dacks and higher summits of northern Vermont. Cold air will again get reinforced behind the system, and we`ll see near 0 to teens for min temperatures. With the light snow and cold weather, it may be wise to plan a few extra minutes for commuting and have coats and everything on hand. && .SHORT TERM /MONDAY THROUGH MONDAY NIGHT/... As of 1251 PM EST Saturday...Snow will taper off Monday. North flow will persist, and temperatures will linger in the 10s, except a few 20 readings in southern Vermont. With fresh snow, we have the potential for another night of early season temperature readings below 0. There will be some clouds this time around, but it`ll arrive relatively late. So we could drop off before we level out. This will likely place Monday night/early Tuesday temperatures at or just above 0 in the broader valley, and approaching -10 F in cold spots. We`ll see how low the perennial cold spot at the Adirondack Airport in Saranac Lake gets. && .LONG TERM /TUESDAY THROUGH SATURDAY/... As of 1251 PM EST Saturday...A unsettled period of weather is expected to continue throughout next week as several disturbances pass through the region, bringing many chances for precipitation. The first shortwave will pass through the region Tuesday afternoon into the evening, bringing some light snowfall to the region, especially across northern New York and the higher terrain of the northern Green Mountains. Temperatures on Tuesday will be on the cool side, with highs generally in the 20s and overnight lows Tuesday night in the teens to low 20s. The next system will move out of the Great Lakes towards the region along the St. Lawrence Valley, bringing another round of widespread precipitation for Wednesday into Thursday. Snowfall is expected at the onset of for all locations, but temperatures during the day Wednesday look to warm enough for a transition to a rain/snow mix or rain within the broader valleys with some warm southerly winds, while higher elevations will likely remain cold enough to remain snow throughout the entire event. The active pattern will continue, with yet another system impacting the region Friday, with even more chances for precipitation. At this time frame, there is still plenty of uncertainty with the track and evolution of this feature, so details will still need to be fine tuned as we get closer. After the brief warm up to near-normal temperatures for Wednesday, temperatures look to trend back to the cooler side for the later half of the week, with highs in the 20s to low 30s and overnight lows in the single digits and teens. && .AVIATION /18Z SATURDAY THROUGH THURSDAY/... Through 18Z Sunday...VFR conditions currently prevail across all terminals this afternoon. These conditions will continue over the next several hours. Some MVFR ceilings will possible for a period overnight, generally between 00Z and 09Z, with conditions improving back towards VFR for the remainder of the forecast period at most terminals. Some light snow showers will be possible this afternoon and evening, primarily at KMSS and KSLK, although the scattered nature of the precipitation will make it tricky to determine overall impacts. If any showers pass overhead, MVFR and even IFR reductions in visibilities may be possible. Winds this afternoon continue to be south to southwesterly, with gusts of 25 knots at some of the valley sites like KMSS and KBTV due to channeling. Winds will continue to be on the breezy side for the next several hours, gradually becoming more northwesterly as the night progresses. Winds are expected to become lighter after 06Z or so. Outlook... Sunday Night: MVFR and IFR. Definite SN. Monday: VFR. NO SIG WX. Monday Night: VFR. NO SIG WX. Tuesday: VFR. Slight chance SHSN. Tuesday Night: Mainly VFR, with areas MVFR possible. Chance SN. Wednesday: Mainly MVFR and IFR, with areas VFR possible. Likely SN, Definite RA. Wednesday Night: Mainly IFR, with areas MVFR possible. Likely SHSN. Thursday: VFR/MVFR conditions possible. Chance SHSN. && .EQUIPMENT... NOAA Weather Radio station WXM-44, transmitting from Mt. Ascutney, Vermont, on frequency 162.475 MHz is non-operational at this time. NWS technicians have diagnosed the problem, but repairs will likely not be able to occur for quite some time due to circumstances beyond our control. Therefore, the time of return to service is currently unknown. The following NOAA Weather Radio transmitters may be able to provide service during this outage: WWG 50 from Burke Mtn, VT at 162.425 MHz and WNG 546 from Hanover, NH at 162.525 MHz. Equipment malfunctions at the Colchester Reef meteorological station will likely leave it inoperable for an extended period of time. This site is not serviced by the NWS. Technicians do not currently have an estimated return to service for this station. Use extra caution when navigating the broad waters of Lake Champlain, and please contact us if you observe winds significantly deviating from the forecast. && .BTV WATCHES/WARNINGS/ADVISORIES...
