Billings, Montana – A more active winter pattern is expected to take shape across Montana, North Dakota, and South Dakota beginning Thursday, with conditions favoring above-average chances for snowfall through the following Wednesday.
According to the National Weather Service Climate Prediction Center, the northern Plains are expected to see increased storm activity during the Jan. 15–21 period. Colder air will be firmly in place across the region, allowing multiple systems to generate snow more efficiently as they track through the northern Rockies and into the Plains.
In Montana, snow chances will be elevated statewide, with repeated impacts possible from west to east. Communities including Billings, Great Falls, Havre, and Miles City could see several rounds of snowfall during the period. Travel along Interstate 90, U.S. 2, and Highway 87 may be impacted at times, especially when snow coincides with gusty winds that reduce visibility and create drifting in open areas.
Across North Dakota, snow potential is highest across central and western portions of the state. Areas such as Bismarck, Minot, Williston, and Dickinson may experience multiple snow events, with slick conditions developing along U.S. 83, Highway 2, and Interstate 94. Strong winds across open terrain could lead to blowing snow and rapidly changing road conditions.
In South Dakota, snow chances are elevated across the western and central parts of the state. Rapid City, Pierre, and surrounding areas could see accumulating snow affecting travel on Interstate 90 and U.S. 14. Open prairie areas may be especially vulnerable to drifting snow during windier periods.
Temperatures during this stretch are expected to support snow lingering on untreated roads, increasing the risk of extended travel issues between systems. Ranchers, truck drivers, and commuters should be prepared for repeated winter disruptions.
Residents across Montana and the Dakotas are encouraged to monitor updates closely, prepare vehicles for winter travel, and allow extra time during snow events. While exact timing and totals remain uncertain, winter weather advisories are increasingly likely as individual systems approach during the Jan. 15–21 window.
