229 FXUS61 KALY 030700 AFDALY AREA FORECAST DISCUSSION National Weather Service Albany NY 200 AM EST Wed Dec 3 2025 .SYNOPSIS... Dry conditions expected today as a small area of high pressure builds in. An Arctic cold front approaching from the Great Lakes and southeast Canada will move across our area late Wednesday night into Thursday, bringing snow showers and some snow squalls along with gusty winds. In wake of the cold front, a bitterly cold air mass will move in Thursday night into Friday with dry conditions. Below normal temperatures will continue into the weekend, with just a low chance of snow showers mainly west of the Hudson Valley. && .SHORT TERM /THROUGH THURSDAY/... Key Messages: - Increasing potential for scattered snow squalls and gusty winds Thursday associated with an Arctic cold front passage. - In wake of the Arctic front, bitterly cold temperatures will take hold Thursday night into Friday. Discussion: As of 200 AM, radar showing light snow over S. VT continuing to shift east and will taper off over the next 1-2 hours as the storm departs into the Canadian Maritimes. Otherwise, mostly cloudy skies in place across the rest of the area with temperatures in the 10s and 20s. Surface ridging extending NE from the mid Atlantic region will result in dry conditions today. Breaks in the clouds are likely, especially in the Hudson Valley. Temperatures will be chilly with highs around 10 degrees below normal(upper 20s to mid 30s) for early Dec. Clouds will increase tonight ahead of an Arctic cold front approaching from the NW. Some snow showers will develop mainly after midnight across the W. Adirondacks in advance and along the Arctic front. The rest of the area looks dry through the night with lows in the mid 10s to mid 20s. As the Arctic front progresses SE across our area on Thu, there is increasing potential for scattered snow squalls developing along the front. Conditions look favorable with forecast soundings indicating steepening low level lapse rates and deep mixing along with ~50-80 J/Kg SBCAPE. Snow squall parameter values are elevated through the afternoon. Temperatures start out just above freezing(lower to mid 30s) in the Hudson Valley, but will drop sharply along the front, so snow squalls could result in impacts on driving conditions despite minor accumulations of < 1" in most areas. The W. Adirondacks and W. Mohawk Valley could get 1-3", but not enough for any headlines. W-NW winds will also get quite gusty Thu afternoon along and behind the front. At this time will mention peak gusts of 25-35 mph across most of the area, but could end up being higher if deeper mixing is realized and taps into stronger winds aloft. Temperatures should drop into the 10s to 20s prior to sunset with the gusty winds making it feel colder. && .LONG TERM /THURSDAY NIGHT THROUGH TUESDAY/... Key Message: - High confidence in below normal temperatures continuing through early next week. Discussion: High pressure builds in from the west Thu night, although there will still be a bit of a breeze into the evening. Once temperatures cool considerably with the high moving overhead later at night into early Fri morning, the winds should become near calm. So while bitterly cold temperatures are anticipated(especially with a fresh snow pack), the lack of overlap with winds should preclude issuance of any Cold Weather Advisories at this time. Will continue to monitor trends. Low temperatures range from 0 to -5F in the higher terrain to 0 to 5F in lower elevations. This will be the first frigid air mass of the season. Dry conditions will persist on Fri, with temperatures "warming" into the upper 10s to mid 20s as high pressure shifts east off the coast. A storm system is expected to track well south of the region across the southern mid Atlantic region Fri night. Most guidance has snow suppressed to our south with just a 20% chance from the NBM south of Albany. Tempertures will remain chilly, but not as cold as Thu night. Below normal temperatures are favored to continue over the weekend and through early next week. A weak disturbance may bring a few light snow showers to areas west of the Hudson Valley on Sat. Then another Arctic cold front is expected to move through late Sun into Sun night. So temperatures will plunge to well below normal levels again Mon into Tue. A clipper system may bring some snow on Tue. && .AVIATION /07Z WEDNESDAY THROUGH SUNDAY/... Through 06z Thursday...Lingering snow showers remain near KALB and KPSF for the first couple hours of the TAF period, and could lead to intermittent MVFR vsby reductions. There are areas with VFR conditions as of 12:10 AM EST and the trend will be for improvement as we head through the rest of the night. However, ALB/GFL/PSF could see periods of MVFR and possibly fuel- alternate cigs through the next several hours to around daybreak. There is also some uncertainty if a brief period of fog/mist could occur at GFL around sunrise if winds become calm there as skies begin to clear. Will also mention low confidence in how long MVFR cigs linger at PSF into this morning. Can`t rule out some brief IFR cigs at PSF, but based on latest obs we have removed the prevailing IFR cigs from the previous TAF. By mid-morning, low to mid-level clouds will diminish. High clouds increase through the day and into tonight, but VFR conditions should prevail at all terminals from mid-morning through the end of the TAF period. N/NW winds at 5-10 kt switch to the W/NW at 5-10 kt around daybreak, then diminish to around 5 kt this afternoon as they turn to the south. S/SE winds of around 5 kt then expected this evening through the end of the TAF period. Outlook... Thursday Night: Low Operational Impact. Breezy. NO SIG WX. Friday: No Operational Impact. NO SIG WX. Friday Night: No Operational Impact. NO SIG WX. Saturday: No Operational Impact. NO SIG WX. Saturday Night: No Operational Impact. NO SIG WX. Sunday: No Operational Impact.
