633 FXUS61 KALY 140759 AFDALY AREA FORECAST DISCUSSION National Weather Service Albany NY 259 AM EST Fri Nov 14 2025 .SYNOPSIS... After a few leftover lake effect rain and snow showers today, high pressure builds overhead resulting in a chilly night tonight. Then, our next disturbance approaches tomorrow into tomorrow night leading to widespread rain showers with periods of freezing rain in parts of the southern Adirondacks, Upper Hudson Valley, and southern Vermont. We turn cooler Sunday through early next week with breezy conditions and additional lake effect snow showers. && .SHORT TERM /THROUGH SATURDAY NIGHT/... Key Messages: - There is a 30 to 60% chance for at least a glaze of ice from freezing rain in the southern Adirondacks, Upper Hudson Valley and southern Vermont late Saturday afternoon into Saturday night. Discussion: Broad mean troughing aloft continues today with winds aloft backing more to the west/southwest. This will result in more fragmented lake effect snow bands limited to the far western Mohawk Valley and northern Catskills with skies giving way to sun over the Hudson Valley. However, as one final shortwave rotates through the southern periphery of the trough this afternoon, winds will veer to the northwest and elicit increased cloud coverage and additional lake effect rain and snow showers, mainly focused in the southern Adirondacks, northern/eastern Catskills, Mohawk Valley, Upper Hudson Valley into western New England. Otherwise, it will once again finish cooler than normal with temperatures rising into the low to mid 40s (upper 40s in the mid-Hudson Valley) with slightly breezy winds. Heading into tonight, strong subsidence builds into the Northeast behind the departing shortwave with ridging from the Great Lakes sliding eastward. This should allow initial partly cloudy skies this evening to give way to clearing. Winds become light and variable and with the ridge axis still positioned to our west, northwest winds will maintain cold and dry air advection. Probabilistic guidance continues to show at least a 60-70% chance for most of eastern NY and western New England to fall under 25 degrees tonight. Values drop to under 40% in the mid-Hudson Valley and southern Litchfield County. Therefore, there is medium to high confidence that we will have a chilly night tonight (coldest in the Adirondacks and southern Greens where there is snow on the ground) with overnight lows ranging from the upper teens to upper 20s. Most of Saturday will be dry as sfc high pressure remains overhead under increasing clouds as moisture spills overtop the ridge axis. Guidance continues to show a shortwave trough in western Ontario deepening, eliciting a sfc low in the eastern Great Lakes that tracks eastward Saturday afternoon. As its associated warm front lift north and eastward, increased warm air and moister advection will result in a precipitation shield that expands and spreads from west to east into eastern NY and western New England mainly between 21 and 00 UTC. Despite the chilly start to Saturday, temperatures during the day should rise into the mid to upper 40s with even pockets of 50 in valley areas. However, with such a dry air mass in place with dew points in the 20s, initial precipitation should lead to cooling temperatures due to wet-bulbing processes. While most should see plain rain through the event, expecting a wintry mix in the southern Adirondacks into the Upper Hudson Valley and southern Vermont where temperatures look to cool towards freezing shortly after sunset into the evening hours. Guidance continues to favor initial rain/sleet mix becoming mainly freezing rain as the warm nose aloft strengthens but the low-levels remain cool (especially in sheltered and valley areas). This can result in a glaze of ice on elevated and cooler surface with even some roads becoming slippery Saturday evening as temperatures hover near freezing. The highest chance for freezing rain is mainly before Midnight after which temperatures gradually warm supporting a transition to plain rain. Should confidence in freezing rain increase, winter weather advisories may needed. Steadiest precipitation expected through 06 - 09 UTC, then the cold front looks to push eastward, ushering in drier and cooler air and transitioning steady rain to showers. && .LONG TERM /SUNDAY THROUGH THURSDAY/... Key Messages: - There is a 50 to 75% for 24 hour maximum wind gusts Sunday and Monday to exceed 35mph with the highest probabilities down the Mohawk Valley, Capital District, northern/eastern Catskills, into western New England. - Increasing confidence for continued below normal temperatures early next week with renewed lake effect snow chances Sunday into Monday, especially in the Mohawk Valley and western Adirondacks. Discussion: We enter into a chilly and windy pattern for the first half of the week as the sfc low from Saturday/Saturday night undergoes cyclogenesis and rapidly deepen as it exits into the Canadian Maritimes. The will likely result in strong west-northwest flow in its wake and induce cold air advection for Sunday into Monday as broad troughing stretches from the Great Lakes into the Northeast. Such a set-up favors not only a lake effect response but potentially even a multi-lake connection, depending on the exact flow regime. The highest chance for more organized lake effect snow bands that extend well inland looks to be Sunday night into Monday but the exact locations where these bands impact will be contingent on the wind direction. A more westerly wind orientation will direct the bands down the Mohawk Valley while a more northwesterly direction will shift the bands a bit south into the northern/eastern Catskills. In addition to lake effect bands, confidence is increasing in upslope snow showers developing over the southern Greens. The lake effect signal looks to become disrupted and weakens Tuesday into Wednesday as additional shortwaves rotate within the mean troughing before ridging builds eastward. Besides the lake effect snow showers, confidence is increasing in windy conditions Sunday into Monday as probabilistic guidance shows 50-70% chance for 24 hour max wind gusts to exceed 35 mph due to the deepening low to our east, steep low and mid-level lapse rates, and tightening sfc pressure gradient. Slightly higher confidence for 35mph+ wind gusts on Sunday when the pressure gradient is tightest. Strongest winds look to be focus down the Mohawk Valley into the Capital District and western MA due to channeled flow. With at least a 60% chance for temperatures to fall under 40 degrees on Monday, the combination of chilly temperatures and breezy winds will likely make Monday the coolest day of the week but temperatures remain seasonably cool the rest of the week. && .AVIATION /08Z FRIDAY THROUGH TUESDAY/... Through 06z Saturday...ALB/GFL/POU remain VFR as of 12:15 AM EST, with MVFR cigs at PSF. Expecting VFR conditions to prevail at ALB/GFL/POU through the entire TAF period, with mainly SCT to occasionally BKN cigs between 4000-6000 ft through the TAF period. There may be more clearing after sunset Friday evening. At PSF, MVFR/fuel alternate cigs expected through early to mid-morning trending to low-end VFR (SCT to BKN at 3000-5000 ft) through the remainder of the TAF period. Have included a VCSH group at POU for the first few hours of the TAF period with some light lake effect showers around, and have included VCSH groups this afternoon/evening at ALB/POU/PSF where a few additional isolated light lake effect rain/snow showers will be possible. Otherwise, winds will be at 5-10 kt from the W/NW from now through the day today with some gusts of around 15kt possible this afternoon. Winds become light and variable by 00- 03z Friday. Outlook...
