Winter Storm Warnings in Jackson, Wyoming
Tucked against the western slope of the Teton Range, Jackson sits in a natural snow trap that generates some of the most impressive seasonal snowfall totals in the American West. Analyzing 13 years of data spanning 2012 through 2024, the area averages 128.9 inches (327.4 cm) of snowfall annually — a figure that reflects both the town's elevation and its exposure to persistent Pacific moisture systems funneled through mountain terrain.
Snowfall is not evenly distributed across the season. February, December, and January tend to deliver the heaviest accumulations, when atmospheric conditions most reliably produce multi-day events. On average, Jackson experiences roughly 0.8 heavy-snow days per year — infrequent, but meaningful enough that residents and visitors should take any watch or warning seriously when one is issued.
Winter storm warnings in Jackson indicate that dangerous accumulations, blowing snow, or severely reduced visibility are expected to create hazardous travel conditions. What qualifies as a warning-level event here may differ from thresholds used in lower-elevation or warmer-climate regions — the National Weather Service calibrates criteria to local geography and historical patterns. Average winter overnight lows hover around 12.3°F (-11.0°C), meaning fresh snow quickly compacts into ice on roads, amplifying the risks that accompany any significant storm.
