Midweek Wintry Mix Brings Snow, Ice, and Wind to Northeast Before Warming Trend

Timing the Transition

The precipitation shield moves in from west to east starting Wednesday evening, likely around dinnertime in New York's North Country and reaching Vermont's Northeast Kingdom by approximately 9 p.m. Snow will be the initial precipitation type before mixing with and changing to sleet and freezing rain overnight. The Champlain Valley and areas west of the Green Mountains are expected to switch to plain rain first. Colder air will linger longer east of the Greens, meaning freezing rain could persist into the Thursday morning commute in those locations. By mid-morning Thursday, lingering wintry precipitation should change to rain as temperatures climb.

Precipitation Breakdown: Snow, Ice, and Rain

Most locations will see only a brief period of snow, resulting in accumulations generally under 2 inches. Higher elevations could pick up slightly more, perhaps up to 4 inches, but the subsequent rain and sharply rising temperatures will quickly compact and melt any accumulation.

The main concern regarding precipitation is the potential for freezing rain, creating icy surfaces. Areas most likely to experience icing include those along and east of the Green Mountains in Vermont (including the NEK), parts of the Adirondacks in New York, and Grafton/Sullivan counties in New Hampshire. Ice accumulations are forecast to be light, generally a glaze up to a quarter-inch, but this is sufficient to make untreated roads and walkways slick.

Wind Factor

Alongside the precipitation, gusty southerly winds will develop late Wednesday night and persist into Thursday morning. The strongest gusts, potentially reaching 40-50 mph or slightly higher, are anticipated in the northern Champlain Valley, the Champlain Islands, and along the northern slopes of the Adirondacks and northern New York.

Temperature Roller Coaster

After the wintry start, temperatures will climb significantly on Thursday. Highs are forecast to reach well into the 60s across western Vermont, while eastern areas will also warm well above freezing by the afternoon, aiding in melting any ice or snow.
