Recreational Forecast
Mountain Forecast:
If you’re planning to hike, ski, or travel through mountain passes today, winter gear will be essential from the start, and you may want to allow extra time for cold conditions. The cold is being reinforced by a high-pressure system settling in from the north, pulling Canadian air south into the region. With that setup in place, temperatures won’t climb much today. Highs at elevation will remain in the single digits, with only the warmest lower elevations reaching the lower teens. Outside activities will be interrupted by showers moving north-northeast during the evening, beginning in the Adirondacks, then crossing the Greens and reaching New Hampshire before midnight. Freezing rain likely on the eastern slopes with ice accumulations between 0.2 and 0.4 with locally higher amounts possible. The icing could lead to downed tree damage and icy trails. Warm air will spread through the region promoting warmer temperatures at higher elevation than the surface. Wintry mix will withdraw into the peaks mid morning leading to widespread rain becoming more scattered in the afternoon. Once the cold front cross early Monday evening, rain will transition into snow and temperatures will free fall into the single digits and below zero overnight. A brief period of dry weather before sunrise and sunset but wrapped around moisture will deliver onther round of light showers Tuesday.
Wind At Lower Elevations:
Light winds are expected to continue through the weekend. Winds off the Atlantic this afternoon with starting to increase, switching to southerly this evening after the warm front passes. Wind picks up slightly to less than 10 mph. Wind will be nearly calm along the surface but southerly tomorrow as snow becomes likely. Winds over Lake Champlain will face a funneling effect ebcoming breezy before the cold front sweeps through, deliveing windspread gusty west winds. Breezy Tuesday between 15 to 25 mph winds with nearly 50 mph wind gust around the peaks. Due to the combination of high winds and cold temperatures, a Wind Chill Advisory will take effect at 4AM EST Tuesday morning.

Detailed Discussion
An upper-level longwave trough organizes the lower levels into a rapidly deepening low-pressure system over the Great Lakes this afternoon. Warm, moist air blows north, so air temperatures will be around or above freezing, but untreated roads will stubbornly remain below freezing. Reaching the Adirondack by the evening, moderate freezing rain spreads across the Greens through the overnight hours. As the warm air builds, freezing rain will retreat into the peaks during the morning, transitioning into widespread rain. Along the northern SLV and deeper valleys east of the Adirondacks and Greens, including the NEK, freezing rain accumulation may reaching upto .2 inches, and less than half inch in the eastern Adirondacks. Decent instability across the Midwest promotes continuing development through Monday evening. Cold front crosses Monday evening with snow showers possible Monday early evening. The dryslot occludes more snowfall, but wrapped around moisture will generate light showers on Tuesday as conditions become gusty.
