135 FXUS61 KBTV 122337 AFDBTV Area Forecast Discussion National Weather Service Burlington VT 637 PM EST Wed Nov 12 2025 .SYNOPSIS... Cool and showery weather conditions will continue to prevail across the region, with a mix of rain and snow showers expected. Showers will gradually taper off and become limited to the summits, with quiet weather expected much of the day Sunday. The potential for rain, with some freezing rain in the Adirondacks and areas east of the Greens remains possible Sunday before we return to elevation dependent rain or snow showers. && .NEAR TERM /THROUGH THURSDAY NIGHT/... As of 627 PM EST Wednesday...Sent out a quick update, mainly to increase PoPs through the overnight hours. Snow showers continue to drift across the region at this hour, especially in northern sections. Precipitation has mainly been snow, though so far impacts have not been as significant as the past couple evenings. This is mostly due to slightly warmer temperatures, allowing roads to generally remain wet. However, roads may become icy in any areas that drop to freezing or below. So motorists should use caution this evening and overnight tonight. Previous discussion...Cool and showery weather will continue across the region the next several days. An area of low pressure centered over southern Ontario will continue to approach the region this evening, reinvigorating chances for showers tonight, especially across more northern areas. Southerly flow across the region has allowed for slightly warmer temperatures within the valleys compared to the last few days, which will allow for more rain or a rain snow mix to fall, while snow will continue across the higher summits. As the low pulls further east from the region, showers will gradually become more orographically influenced. Snowfall amounts remain largely similar to the previous forecast, with a coating to 1" expected in the lower valleys, 1-2" along foothills, 2-5" for the favored northwestern slopes and 5-10" across the northern summits. Temperatures overnight tonight will be milder compared to previous nights, with lows generally in the 20s to mid 30s. Another day with temperatures in the 30s to lower 40s is expected for Thursday, which will continue to allow for rain within any showers in valley locations. && .SHORT TERM /FRIDAY THROUGH FRIDAY NIGHT/... As of 157 PM EST Wednesday...Some lingering showers can be expected throughout the day Friday, primarily tied to the higher summits. As moisture thins throughout the day, chances for showers even across the higher summits will wane, with relatively quiet weather expected Friday night. Snowfall accumulations across the higher terrain will be fairly minor during this time frame given the decreasing showers and moisture. Daytime highs on Friday will continue to be on the cool side, with temperatures reaching into the 30s to near 40. Overnight lows will be quite chilly, with most places dropping into the teens and 20s. && .LONG TERM /SATURDAY THROUGH WEDNESDAY/... As of 157 PM EST Wednesday...Focus for the extended is on Saturday evening into Sunday as low pressure tracks towards the region. The position and trajectory of the low support cold air in place with a warm frontal passage likely overnight. Model thermal characteristics and the synoptic pattern are indicative of freezing rain chances, especially east of the Green Mountains where coldest air will pool before being scoured out by southerly flow. Big questions remain for duration of freezing rain in the Champlain Valley where channeled winds will likely deepen the warm layer more quickly shifting precip character more towards rain. Still, surface temperatures will be cold to start with, so some freezing rain remains possible. Continued southwesterly flow will favor warming profiles Sunday switching most locations to rain with higher elevations possibly remaining all snow. The system will pass with temperatures falling again Sunday night with more chances of snow on the backside of the system. Model output favors cold temperatures to remain over the region with mean long wave troughing centered over the Northeast. This pattern will support continued shower chances with potential for upslope showers on western slopes. Temperatures are likely to range in the 30s to low 40s for highs with 20s in general for overnight lows outside of the Adirondacks where upper teens are more likely. . && .AVIATION /00Z THURSDAY THROUGH MONDAY/... Through 00Z Friday...There is a mix of conditions across northern New York and Vermont as widespread showers spread eastward. Generally expect MVFR to prevail with occasional drops in both ceilings and visibility to IFR. The most likely sites to see IFR conditions will be KSLK/KMSS/KMPV/KEFK. Precipitation will mostly fall as snow, but rain may mix in from time to time, mainly at KMSS/KPBG/KBTV. Showers will wind down 04z-08z, lingering longest in the northern Green Mountains. Anticipate MVFR to prevail at all terminals once the precipitation ends. South/southwest winds generally less than 10 kt this evening though localized gusts to 20 kt will be possible at KMSS and KBTV. Winds light and variable overnight, then trending toward W/NW and increasing to 7-14 kt after 14z. Showers will be possible in the higher elevations again on Thursday, but coverage not enough to include mention in the TAFs at this time. Outlook... Thursday Night: Mainly VFR, with areas MVFR possible. Chance SHSN. Friday: Mainly VFR, with areas MVFR possible. Chance SHSN. Friday Night: Mainly VFR, with areas MVFR possible. Slight chance SHSN. Saturday: Mainly VFR, with local MVFR possible. Chance FZRA. Saturday Night: MVFR/IFR conditions possible. Definite RA, Chance FZRA. Sunday: Mainly MVFR, with areas IFR possible. Likely SHRA, Likely SHSN, Definite FZRA. Sunday Night: Mainly VFR, with areas MVFR and IFR possible. Likely SHSN. Monday: Mainly VFR, with areas MVFR possible. Chance SHSN. && .MARINE... Southerly winds on Lake Champlain continue to be between 20 and 25 knots sustained, with occasionally higher gusts. Winds will gradually diminish this evening as they shift to become more westerly. && .BTV WATCHES/WARNINGS/ADVISORIES... VT...None. NY...None. && $$ SYNOPSIS...Kremer NEAR TERM...Hastings/Kremer SHORT TERM...Kremer LONG TERM...Boyd AVIATION...Boyd/Hastings MARINE...Kremer
