147 FXUS61 KBTV 172328 AFDBTV Area Forecast Discussion National Weather Service Burlington VT 628 PM EST Mon Nov 17 2025 .SYNOPSIS... Persistent northwest flow and a prolonged period of upslope snow across the Adirondacks and Greens will continue through the first half of the week. Snow showers will eventually taper off on Tuesday. Drier weather moves in Wednesday and Thursday. && .NEAR TERM /THROUGH TUESDAY NIGHT/... As of 617 PM EST Monday...Issued a quick update this evening, mainly to increase PoPs across the favored upslope areas in the higher terrain. Radar shows some increased shower activity along the western slopes of the Greens and Adirondacks, and surface observations/web cams show fairly widespread light snowfall in these areas. Have therefore increased precipitation chances to 50-75% in these areas, especially this evening and into the early overnight hours. Accumulations through daybreak will mainly be an inch or less, though the spine of the northern Greens, higher elevations in the Northeast Kingdom, and the High Peaks in the Adirondacks could see 2-4 inches. Valleys will see flurries at most. Otherwise, the forecast is in good shape and no other changes were needed. Previous discussion...As low pressure continues to shift further east of our region, snow shower activity has begun to wind down. Still think that some sort of light snow showers will continue in the high elevations tonight and into Tuesday, but have cancelled headlines because the bulk of the accumulating snow has ended. Any additional accumulations will only be light. Winds will begin to decrease as well with pressure gradient slackening as low moves further away from the region. Until the winds weaken further, blowing snow and lower visibilities will be possible. Minimum temperatures overnight will dip into the upper teens to upper 20s. Winds will continue to gust 15 to 25 mph overnight, and wind chills will be as low as the single digits above zero in the Adirondacks. High pressure will begin to build into the region on Tuesday and lower levels will dry out, then snow showers will completely come to an end. High temperatures on Tuesday will range from the lower 30s to lower 40s. Some peeks of sunshine are expected by the afternoon in the Champlain valley. Lows overnight Tuesday night will be in the teens to upper 20s. && .SHORT TERM /WEDNESDAY THROUGH WEDNESDAY NIGHT/... As of 140 PM EST Monday...Wednesday and Wednesday night will be quieter as high pressure ridges into the area. Will have some welcome sunshine on Wednesday and high temperatures will reach the mid 30s to lower 40s, lows will be in the teens to lower 20s with good radiational cooling. && .LONG TERM /THURSDAY THROUGH MONDAY/... As of 1230 PM EST Monday...High pressure will continue overhead by mid to late week keeping temperatures on the mild side for fall standards. Highs Tuesday and Friday will be in the low 40s with overnight lows in the mid to upper 20s to near 30. Our flow pattern becomes zonal and southerly by Thursday with continued drying, though still cloudy, conditions. Our next system arrives Friday, with new guidance suggesting a drier system with a break in the jet stream. While the GFS shows a single jet streak moving over the region associated with this system, the ECMWF depicts two weaker streaks, one over the North Country, and another to our south more over the Mid-Atlantic. This break is looking more likley in a run to run analysis which would lead to a weaker more scattery system for Friday into Saturday. Ensemble guidance varies from a few tenths to a quarter to half an inch between the EPS and GEFS. Precipitation type variability also remains, though less so in recent model runs. Some shallow residual cold air near the International Border and Northeast Kingdom, and near summits should be able to keep snow for a few hours Friday before a switch to all rain occurs by the afternoon. A wintry mix cannot be ruled out in the cold hollows of the northern portions of the region as well. Furthermore, breaks in the precipitation could lead to some mixed down breezy conditions Friday into Friday night between showers. Gusts right now look to be confined to the higher summits of the Adirondacks and Greens, and locations near Lake Champlain. The system quickly exits the area by Saturday afternoon with some light lingering upslope rain/snow showers in the Adirondacks and northern Greens through the weekend as cyclonic flow persists. && .AVIATION /23Z MONDAY THROUGH SATURDAY/... Through 00Z Wednesday...MVFR/VFR to prevail through the entire TAF period. Light snow showers will persist across the higher terrain overnight, with KEFK/KSLK to see the biggest impacts. Visibility 2-4SM will be possible in any snow at these terminals. Otherwise, only flurries are anticipated, and then it should be mostly confined to the mountains. Ceilings will remain MVFR at most terminals through much of the period, with KPBG and KRUT the only sites expected to remain VFR. Clouds will start to dissipate Tuesday afternoon, so improving conditions to VFR are expected by the end of the TAF period. W/NW winds will remain gusty through much of the period as well, generally 6-12 kt with gusts 20-25 kt. Outlook... Tuesday Night: VFR. NO SIG WX. Wednesday: VFR. NO SIG WX. Wednesday Night: VFR. NO SIG WX. Thursday: VFR. NO SIG WX. Thursday Night: VFR. Chance RA, Chance SN. Friday: Mainly MVFR, with local IFR possible. Definite RA. Friday Night: Mainly MVFR, with local IFR possible. Chance SHRA, Chance SHSN. Saturday: MVFR. Slight chance SHRA, Slight chance SHSN. && .MARINE... A Lake Wind Advisory is in effect for all areas of Lake Champlain with northwesterly winds 15 to 30 knots, becoming westerly with gusts as high as 35 to 40 knots possible. Waves will be around 2 to 5 feet, subsiding slightly to 1 to 4 feet. Strong winds as high as 20 to 25 knots are forecast to continue tonight. && .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. && .BTV WATCHES/WARNINGS/ADVISORIES...
