773 FXUS61 KBTV 090526 AFDBTV Area Forecast Discussion National Weather Service Burlington VT 1226 AM EST Tue Dec 9 2025 .SYNOPSIS... Dry, but very cold conditions will continue to prevail across the region tonight into tomorrow morning before south winds begin to increase during the day tomorrow. Several rounds of snow are expected throughout the week, with the most widespread precipitation expected to occur Wednesday into Wednesday night. After a brief warm up mid week, colder temperatures will return by week`s end. && .NEAR TERM /THROUGH WEDNESDAY/... As of 648 PM EST Monday...Updated forecast to lower overnight minimum temperatures a bit as temperatures area already dropping sharply. Lows will reach the teens below zero in the coldest spots of the Greens and Dacks. Most over Vermont should dip below zero, with the warmest temperatures expected along Lake Champlain. Previous discussion follows. Dry but cold conditions are expected to continue tonight into the first portion of the day tomorrow as the region remains under the influence of high pressure. Despite the sunshine across the region this afternoon, temperatures have only warmed into the single digits and teens as of 1 PM this afternoon. The cold conditions will continue through the overnight hours, with a fresh snowpack and mostly clear skies allow for ideal radiational cooling. Current forecast currently shows overnight lows dropping to near to below zero areawide, with portions of the Adirondacks and Northeast Kingdom close to -15F, although these values could change if cloud cover moves into the region faster than anticipated. A gradually warming trend is expected during the day tomorrow as winds become more southerly ahead of a weak shortwave expected to pass through the region Tuesday night. Channeling in the Champlain Valley will allow for breezy conditions, with gusts up to 30 mph possible, while elsewhere gusts will likely remain under 20 mph. The southerly flow will allow for warmer temperatures compared to today, with highs in the upper teens and 20s. The shortwave, and any associated precipitation, will arrive Tuesday evening, with just a light dusting of snow expected in most locations, with a possible inch or so expected across the higher terrain and portions of St. Lawrence County. This system will quickly exit the region by Wednesday morning, with the next system quickly following behind for Wednesday. && .SHORT TERM /WEDNESDAY NIGHT/... As of 119 PM EST Monday...The active period of weather will continue as another system moves into the region, bringing widespread precipitation to the region. The latest guidance continues to support widespread snowfall across the region, with more limited potential for some rain to mix into the broader valleys during the afternoon. South winds ahead of the low will allow daytime temperatures to rise into the low to mid 30s, but given cold profiles, would anticipate most of the precipitation to fall as snow. Winter Weather Advisories may be needed for portions of northern New York and areas along the Green Mountains with snowfall amounts of 4 to 6 inches possible, with locally higher amounts possible across the summits. Elsewhere, 1 to 4 inches of snowfall are expected, but trends will need to be monitored as we get closer as any changes in thermal profiles will likely impact snowfall accumulations. Hazardous travel conditions will be possible, especially during the Wednesday evening commute, so any travelers will need to use caution. && .LONG TERM /THURSDAY THROUGH MONDAY/... As of 119 PM EST Monday...Upslope and lake effect snow showers are expected to linger on Thursday and Thursday night as surface low pressure pulls northward from the Gulf of St. Lawrence through Newfoundland and Labrador and flow continues out of the west across the forecast area. Global deterministic models continue to show disagreements between one another on location and track of an upper level low pressure during this period, which could impact how widespread and persistent the snow showers are. Regardless, snow should be relatively light and temperatures Thursday and Friday look to swing back below seasonal normals. Highs forecast in the 20s and lower 30s, and lows those nights will likely fall back into the single digits to mid teens. Temperatures keep trending downwards into the weekend and early next week under moderate cold air advection with highs only reaching the mid teens to lower 20s and lows getting down as low as negative single digits above and below zero. Model consensus is not super strong during this period either pertaining to our next quick clipper type system that could bring additional snowfall to the region, and the timing and track of the system would also impact the timing and strength of cold air. It`s difficult to identify the clipper system itself on model solutions, and it may come down to more orographically enhanced snow showers with an upper shortwave than a real defined surface feature. && .AVIATION /05Z TUESDAY THROUGH SATURDAY/... Through 06Z Wednesday...TAF challenge in the next 6 hours will be if some low stratus clouds could develop at BTV/MPV or EFK and produce localized intervals of IFR cigs. Crntly temp dwpts spread is large, but GOES 19 nighttime microphysics imagery shows some lake enhanced clouds building over the central/southern Lake Champlain area at this time. Given this development have tempo`d btwn 09-12z 2SM BR BKN004, to cover this probability given satl trends. Otherwise, VFR conditions prevail with developing south/southwest 10 to 15 knots gusts 15 to 25 knots likely after 15z today. A band of light snow with mvfr vis and vfr cigs develops after 00z across our northern NY taf sites and spreads into VT toward 03z Weds. Outlook... Wednesday: MVFR/IFR conditions possible. Definite SN. Wednesday Night: Mainly MVFR, with local IFR possible. Chance SHSN. Thursday: VFR. Chance SHSN. Thursday Night: VFR. Slight chance SN. Friday: Mainly VFR, with local MVFR possible. NO SIG WX. Friday Night: Mainly VFR, with areas MVFR possible. Slight chance SN. Saturday: Mainly VFR, with areas MVFR possible. Chance SN. && .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...
