365 FXUS61 KBTV 060608 AFDBTV Area Forecast Discussion National Weather Service Burlington VT 108 AM EST Sat Dec 6 2025 .SYNOPSIS... Fair weather will prevail through early this morning before lake effect snow showers develop downwind of Lake Ontario for the afternoon and evening. A clipper system will bring a renewed chance of widespread light snowfall late Sunday and Sunday night. A few inches of snow accumulation is expected. Colder conditions return for Monday and Monday, while unsettled weather continues through much of next week. && .NEAR TERM /THROUGH TONIGHT/... As of 1254 AM EST Saturday...A wide range in temperatures early this morning, ranging from the upper teens and low 20s in the larger valleys to the single digits above and below 0F in the Adirondacks and eastern VT. Clouds will gradually increase through daybreak, so temperatures should start to hold steady, especially in the Adirondacks, though eastern VT could see a little additional cooling. Temperatures will warm in earnest through the day today as flow turns to the south/southwest ahead of an upper trough/surface front approaching from the Great Lakes. Highs will be in the low/mid 30s in most areas, though a few of the more sheltered locations in eastern VT may remain in the upper 30s. Still, it will be quite a bit warmer than yesterday. Winds will be a bit on the breezy side, especially in the St Lawrence and Champlain Valleys due to channeling. The winds will also result in lake effect snow showers downwind of Lake Ontario as the cool air moves over the relatively warm waters. The band will waver from the southern St Lawrence Valley toward the western Adirondacks as winds turn southwest and eventually west/southwest. The air/water temperature differential isn`t all that impressive, so showers will be somewhat unorganized and shouldn`t make it too far from the lake. Any accumulation will be an inch or less. Additional shower chances will develop this evening as the aforementioned cold front pushes southward across the region. Both significant moisture and forcing will be lacking, but isolated to scattered snow showers will be possible across the northern Adirondacks and into the northern Greens through about midnight as the boundary moves through. Much colder air will rush in behind the front, and expect northern areas will once again be in the single digits and low teens by daybreak, while southern sections will mainly stay in the teens. Snow will be an inch or less, perhaps a couple of inches over the higher northern summits. && .SHORT TERM /SUNDAY THROUGH MONDAY/... As of 1254 AM EST Saturday...Widespread light snow expected for the start of next week as a weak clipper low treks across the region. Sunday starts out dry with clouds quickly increasing from west to east during the morning and early afternoon hours. Snow will likewise gradually spread eastward, holding off until the late afternoon/early evening in the St Lawrence Valley, and then moving into the remainder of the area overnight. The system is a fairly fast mover, so snow will have ended by daybreak Monday for all but the far Northeast Kingdom. Snowfall will be fairly uniform given lack of strong forcing and light winds through much of the day and into the overnight hours. However, winds will turn to the northwest late Sunday night into Monday behind the system, bringing a reinforcing shot of colder air for the start of the work week. Snow totals will be a general 1 to 3 inches, just enough to freshen the snowpack and perhaps make for some slick travel. Highs on Sunday will range from the upper teens along the international border to the upper 20s/near 30 in south- central VT. Just about everyone will drop into the single digits by Monday morning, with some below zero readings likely in the Adirondacks. Monday will be cold with brisk northwest winds. Highs will only be in the teens with a few spots in far southern sections possibly breaking into the low 20s. Given the breezy winds, wind chills will stay in the -5F to +5F range in most areas during the afternoon. The higher summits will be even colder, as highs will only be in the single digits. This combined with winds gusting to 25+ mph will result in daytime wind chills as cold as -25F. && .LONG TERM /MONDAY NIGHT THROUGH FRIDAY/... As of 107 AM EST Saturday...Another cold night is expected Monday night into Tuesday. High pressure will be shifting east and high clouds will move into the area. Temperatures will range an both sides of zero, with spots in the Dacks reaching -10F. The cloud cover will be the key, as right now the NBM is leaning towards higher clouds which could still allow for more radiational cooling and even colder overnight lows across the region. An upper level trough swings through late Tuesday and brings some chances for some light snow, especially across the higher terrain. Then, a larger system moves through Wednesday night into Thursday, with yet another on late Friday. Temperatures will become more mild and move back towards the freezing mark by midweek, so while the NBM is leaning primarily snow, it is possible that we see some rain and wintry mix in the back half of next week depending on low pressure tracks for each system. && .AVIATION /06Z SATURDAY THROUGH WEDNESDAY/... Through 06Z Sunday...VFR currently at all stations except KRUT which is seeing some MVFR ceilings due to a push low level clouds from the southwest. Surface high pressure will shift off the New England Coast tonight with developing south winds at 4 to 8 knots. These winds will increase on Saturday with localized gusts 15 to 25 knots possible, especially MSS/PBG and SLK. Given the dry air at the surface, any precipitation will have difficulties reaching the ground thru 18Z Saturday with VFR conditions prevailing at all sites. Eventually a few light snow showers may impact SLK/MSS after 21Z with some lowering CIGS toward MVFR conditions expected at KMSS/KSLK/KPBG/KBTV between 22Z - 02Z. Outlook... Sunday: Mainly VFR, with local MVFR possible. Chance SN. Sunday Night: Mainly VFR, with areas MVFR possible. Chance SN. Monday: VFR. NO SIG WX. Monday Night: VFR. NO SIG WX. Tuesday: VFR. Chance SN. Tuesday Night: Mainly VFR, with areas MVFR possible. Chance SN. Wednesday: MVFR/IFR conditions possible. Likely SN, Likely RA. && .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...
