290 FXUS61 KBTV 290225 AFDBTV Area Forecast Discussion National Weather Service Burlington VT 1025 PM EDT Thu Aug 28 2025 .SYNOPSIS... A cold front is slowly pushing into the region from the west with some much needed beneficial rain. Gusty winds will remain across the channeled valleys today, but should weaken tonight as precipitation and cloud cover increases. Showers and cooler conditions will linger into the weekend, with seasonable temperatures and plentiful sunshine returning for next week as high pressure builds overhead. && .NEAR TERM /THROUGH SATURDAY/... As of 229 PM EDT Thursday...A cold front will continue to slowly approach the St. Lawrence Valley with precipitation expected to begin by mid afternoon across northern New York. Ahead of the front, southerly winds are impressively gusty for modeled soundings. Winds are exceeding the mixed down potential from modeled soundings with gusts up to 30 mph observed on Lake Champlain, and between 20 to 25 mph elsewhere in the St. Lawrence and Champlain Valley. Outside of the main valleys, winds will be breezy with gusts up to 15 mph. As the front moves further into the region tonight, cloud cover should limit higher winds, but channeled flow in the Champlain Valley, could yield some occasional lingering gusty conditions. The front will finally bring some beneficial rainfall to most of northern New York where many locations have missed out on recent rainfall events. Due to the prolonged dryness, the entire region is classified as abnormally dry with portions of the Adirondacks, and central and northeastern Vermont in a moderate drought. As the front moves through, showers will be relatively short lived though, perhaps only for a few hours. However, precipitation amounts through Friday night will range from near an inch in the St. Lawrence Valley to a third of an inch in the Champlain Valley, and around a quarter of an inch east of the Greens. Showers will reach into Vermont by tomorrow morning, with showers continuing into the Northeast Kingdom by tomorrow afternoon as the front weakens. Temperatures overnight tonight will dip towards the upper 40s in the higher terrain, and mid 50s in the valleys, but we should not see a big cool off with precipitation and cloud cover over the area. As the front clear tomorrow afternoon, caa will take over with highs only in the 60s for many locations. Into the mountains, cooler air will push summit level temperatures into the 40s. Lows Friday night will feel closer to fall with everyone away from Lake Champlain feeling temperatures below 50, with some mountain locations potentially dipping into the mid to upper 30s. While confidence is low agriculture interested in the Adirondacks should pay close attention to the forecast for any potential frost/freeze potential. && .SHORT TERM /SATURDAY NIGHT/... As of 229 PM EDT Thursday...Cooler air will continue to filter into the region as caa increases. The upper-level low will slowly cyclonically rotate to the east Saturday, but will leave some lingering shower chances across the higher terrain. Blocked flow amd 925mb temperatures just under 10C, should allow for some light upslope rain showers in the Greens and the Adirondacks. Precipitation amounts will be low however, with only a a few hundreths, particularly along the international border. High temperatures will be about 10 degrees below average with values in the 60s areawide. Clouds will slowly clear out Saturday night which could lead to another good radiational cooling night. Temperatures will fall back below 50 with the potential for upper 30s in the higher terrain Saturday night. && .LONG TERM /SUNDAY THROUGH WEDNESDAY/... As of 229 PM EDT Thursday...Precipitation chances trend lower on Sunday, with any showers more likely across northeastern Vermont. While PoPs are largely 10 to 20% in far northeastern areas, coverage of scattered showers is somewhat uncertain due to model differences in how far north and east the upper level low will be positioned. Otherwise, a large ridge of high pressure still is expected to build into the region from the west. As such, skies will trend sunny, helping temperatures rise several degrees higher than on Saturday, and an extended dry period will commence. Temperatures will largely be near to above normal during the daytime and near to below normal at night with dry conditions and light winds, especially through Wednesday. The only weather of note in the long term is next Thursday as there is a general consensus in the model guidance of another larger trough digging across the western Great Lakes region. Depending on how much moisture return and where cyclogenesis occurs ahead of the trough will determine if rain chances begin in our region that day or is delayed further into the week. The current six hourly PoPs represent a blend of the faster and slower scenarios, such that shower chances are low Thursday morning, and only increase into the 20 to 40% range during the afternoon. The dynamics for this potential low pressure system could supply substantial rainfall, so stay tuned. && .AVIATION /03Z FRIDAY THROUGH TUESDAY/... Through 00Z Saturday...A cold front is driving showers through northern New York from northwest to southeast this evening, with most reported rainfall visibilities 3-6 miles so far. While there could be pockets of heavier rain, we are predicting that visibilities will stay 3 miles or higher with the majority of rainfall over the next 24 hours. Steady, high confidence rain is expected to come to an end at MSS around 08Z, followed by some on and off ceilings 600-800 feet above ground level. SLK will likely follow suit with steady rain ending around 10Z, followed by a mist of 2-6 miles and ceilings 700-900 feet. Ceilings at these NY sites are anticipated to increase again around 14Z to about 1800-2000 feet, then continue to rise towards VFR around 18Z-20Z. Meanwhile, southwesterly to westerly winds will be in place 3-9 knots. Looking at sites farther east, we see lower probabilities of IFR conditions over the next 24 hours. Most likely period of rain will be 11Z-20Z, though PBG would be most likely to see an earlier start time than the others. Ceilings will fall into the 1000-3000 foot range for a period at most sites, returning to VFR levels by tomorrow afternoon. Winds will be turning with the frontal passage, from southerly to more westerly or even northwesterly by the end of the 24 hour TAF period. Outlook... Friday Night: VFR. Slight chance SHRA.
