Sheridan, WY – Northern Wyoming heads into the holidays under an “equal chances” temperature outlook, but forecasters say residents should still expect several opportunities for snow from December 20 through January 2. With Christmas and New Years falling inside this period, the region may see classic winter conditions for holiday travel.
According to NOAA, northern Wyoming—including Sheridan, Cody, Buffalo, Gillette, and the Bighorn Mountains—sits within a broad EC temperature band covering much of the western and central U.S. While this does not signal a strong warm or cold trend, the region’s late-December climate heavily favors snow, especially at higher elevations and during overnight hours.
Precipitation is also forecast in an equal-chances zone, meaning totals should remain near seasonal norms. In northern Wyoming, “seasonal” typically means frequent light to moderate snowfall, with the potential for heavier bursts when stronger systems pass through. Mountain areas may see significant accumulations, while basin regions could experience both snow and occasional mixing depending on temperature swings.
Communities along I-90, U.S. 14, and U.S. 16 should prepare for slick roads, periods of reduced visibility, and gusty winds, especially where snowfall interacts with open terrain. The Bighorn Mountains are likely to see more consistent and heavier snow, raising confidence in a White Christmas for higher elevations.
Lower elevations—including Sheridan, Buffalo, and Cody—will likely see several rounds of snow, though mixing remains possible when temperatures briefly moderate.
If timing aligns, northern Wyoming may enter 2026 with a fresh blanket of snow and continued wintry conditions.
Travelers are advised to monitor updated forecasts as storm timing and intensity become clearer.
