Billings, Montana – A prolonged and potentially harsh winter pattern is expected to dominate eastern Montana as the New Year approaches, with strong signals for frequent snow, bitter cold, and hazardous travel from Dec 27 through Jan 9.
Large-scale atmospheric patterns favor repeated intrusions of Arctic air into the northern Plains during this period. According to the National Weather Service in Billings, colder-than-average temperatures are likely to persist, allowing most precipitation to fall as snow. Eastern Montana, including Yellowstone, Rosebud, Custer, and Powder River counties, shows a strong signal for multiple snow events rather than a single major storm.
Snowfall is expected to arrive in several waves, increasing the risk of recurring travel disruptions. Open terrain combined with gusty winds may lead to blowing snow and sharply reduced visibility, particularly along I-90, I-94, US-87, and US-212. Even modest snowfall could create dangerous conditions when paired with strong winds and falling temperatures.
Arctic cold outbreaks during the period may drive wind chills well below zero, raising concerns for livestock, infrastructure, and anyone traveling long distances. Brief warmups are possible between systems, but temperatures are expected to trend below seasonal norms overall, increasing the risk of icy roadways during overnight hours.
The Montana Department of Transportation urges drivers to prepare for rapidly changing conditions, carry winter survival kits, and avoid unnecessary travel during active snow and wind periods. Residents are encouraged to protect exposed pipes, check heating systems, and ensure livestock have adequate shelter.
While short breaks between systems are expected, the overall setup supports a cold, snowy, and high-impact start to 2026 across Billings and much of eastern Montana, with winter hazards persisting into early January.
