242 FXUS61 KALY 210606 AFDALY AREA FORECAST DISCUSSION National Weather Service Albany NY 106 AM EST Fri Nov 21 2025 .SYNOPSIS... A weather system to our north brings low chances for precipitation in the western Adirondacks and Mohawk Valley today. Otherwise, dry conditions continue today. For tonight into tomorrow morning, a weather system to our south continues to trend further southward for low chances of precipitation across the Mid-Hudson Valley, southern Taconics, and Litchfield Hills. Dry conditions are in store for Saturday. Sunday is looking to be unsettled for the western Adirondacks and Mohawk Valley region as a weather system arrives from the north. A gradual warming trend for next week with chances for precipitation returning Tuesday into Thanksgiving. && .SHORT TERM /THROUGH SUNDAY NIGHT/... For this morning...Cold temperatures start the day with temps ranging in the teens and 20s. Clouds continue to increase this morning with dry conditions in store. Very low chances (less than 15%) for a light snow shower in portions of the western Adirondacks and Mohawk Valley between 5 AM and 8 AM, otherwise dry conditions continue. For this afternoon and tonight...An approaching weather system from the northwest brings low chances (15-30%) to the western Adirondacks and Mohawk Valley through the early evening hours. Then dry conditions return as this system heads northward. Elsewhere, dry conditions are in store for today with mostly cloudy skies. For late tonight into the very early morning hours tomorrow, low chances (15-25%) for light rain showers across the Mid-Hudson Valley, southern Taconics, and Litchfield Hills as a weather system moves through to our south. latest high resolution model guidances and National Blend of Model data (NBM) continues to trend further southward for accumulating precipitation amounts. Very light amounts of a trace to 0.05 inches across the Mid-Hudson Valley, southern Taconics, and Litchfield Hills could occur but latest probabilities are very low as the trend of the weather system is to stay just to our south and move through quickly. Dry conditions are in store by daybreak for Saturday morning. Dry conditions are in store for a pleasant, but chilly Saturday. As a cold airmass continues overhead, highs range in the low 30s to 40s. Low temperatures range in the teens and 20s. Once the sun sets, temperatures fall quickly as skies are mostly clear but should hover in the 20s as clouds increase for Sunday morning. For Sunday, low to medium chances (15-50%) for light snow showers in the western Adirondacks and Mohawk Valley as a weather system arrives from the northwest. This weather system stays just to our north where the most favorable locations to see a light dusting to a half of an inch of snowfall is in the western Adirondacks. For the Mohawk Valley, temperatures could stay cold enough for snow showers during the morning hours but as we head into Sunday afternoon with temperatures warming above freezing, snow showers transition over to light rain showers. At this forecast period for the Mohawk Valley, chances for these showers are between 15-30% as the weather system is favored by the latest forecast models to stay to our north. By Sunday night, the weather system heads further northward and dry conditions return for Sunday night into Monday morning. Elsewhere across eastern New York and western New England, dry conditions continue for Sunday with highs in the 30s and 40s. && .LONG TERM /MONDAY THROUGH THURSDAY/... Key message: - Mild with rain Tuesday into Wednesday, then turning colder and breezy by Thanksgiving Day. Discussion: A northern stream short wave with limited moisture could bring some light rain/snow showers Sun into Sun night, mainly for higher terrain areas north/west of the Capital District. Temperatures look slightly below normal. Dry weather with seasonable temperatures expected Mon into Mon night, as surface high pressure drifts east across the area. The next chance of widespread precip arrives on Tue into Tue night, as a progressive open wave upper trough approaches from the south/west, with an associated warm front. There is a good likelihood of at least some measurable precip, with NBM probs showing 20-40% for > 0.50" so it does not look overly heavy. Also temperatures should be warm enough for rain across most of the area, although brief mixing with snow may occur in the highest elevations of the S. Adirondacks. The parent cyclone looks to track well north of our area on Wed, so our region may get into a pseudo warm sector prior to the system`s cold front passage. NBM guidance showing high temperatures in the mid to upper 50s in most lower elevation areas. Additional showers are expected along the cold front Wed P.M. In wake of this system, colder air is expected to filter in Wed night into Thu bringing gusty west winds, below normal temperatures and lake effect snow in some favored areas. && .AVIATION /06Z FRIDAY THROUGH TUESDAY/... Flying conditions are currently VFR across the region. IR satellite imagery shows a large area of high clouds moving across the region from the west. In addition, some lower stratus clouds are moving across the Southern Tier of New York. Some additional lower clouds can also be seen well upstream over southern Ontario and far western New York. These clouds will spreading towards the area for the late night hours, so will allow for stratus clouds to build into the area from the west between 07z-11z. KPOU may be the first site impacted by stratus based on satellite trends, with the other sites later in the overnight hours. Within the stratus, flying conditions will either be high-end MVFR or low-end VFR, with cigs around 2500-3500 ft. Winds will continue to be calm through the rest of the overnight hours. After sunrise, these lower stratus clouds will stay in place for a portion of the day There may be some improvement back to low-end VFR for KALB/KPOU, but the other sites will likely stay MVFR with the stratocu staying in place. Southerly winds will be 5 to 10 kts on Friday. At this point, will mention a VCSH at KGFL, but none of the other sites, as any brief showers will be fairly isolated and have little to impact on visibility. Behind a cold front, winds will switch to the west for Friday night around 5 kts or so. Some drier air will start working into the area, so there may be some improvement in ceilings for all sites, although KPSF may still continue to be MVFR even into Friday night. Otherwise, it will be dry with no precip on Friday night. Outlook... Saturday Night: No Operational Impact. NO SIG WX. Sunday: No Operational Impact. NO SIG WX. Sunday Night: No Operational Impact. NO SIG WX. Monday: No Operational Impact. NO SIG WX. Monday Night: No Operational Impact. NO SIG WX. Tuesday: Moderate Operational Impact. Chance of SHRA. Tuesday Night: High Operational Impact.
