Sheridan, Wyoming – Rain changing to snow Monday evening could quickly turn roads slick across the Montana–Wyoming border region, creating hazardous travel along Interstate 90 and nearby highways through Wednesday morning.
According to the National Weather Service in Billings, a Winter Weather Advisory begins at 4 p.m. Monday for southern Big Horn County in Montana and the Sheridan foothills of northern Wyoming. Snowfall totals between 1 and 3 inches are expected in lower elevations including Sheridan, Ranchester, Dayton, and Lodge Grass, with up to 5 inches possible across the higher hills south of Sheridan along I-90. The advisory remains in effect until 8 a.m. Wednesday.
Forecasters say precipitation will likely begin as rain Monday afternoon before temperatures drop during the evening, allowing roads to freeze and snow to accumulate overnight.
In the nearby northeast Bighorn Mountains, including Story and Burgess Junction, heavier snowfall between 4 and 8 inches is expected with wind gusts up to 30 mph Tuesday. Snow-covered stretches of U.S. Highway 14 could lead to difficult travel through higher terrain.
Farther north in Montana, additional winter weather advisories remain in effect early Monday across central and north-central parts of the state, including Great Falls, Lewistown, and Havre. Those areas could see up to 3 inches of additional snow with wind gusts reaching 45 mph before conditions improve later in the morning.
Drivers are urged to slow down, allow extra travel time, and check current road conditions through the state’s 511 systems before traveling. Additional updates or advisories may be issued as the system continues through midweek.
