A powerful winter storm is forecast to bring heavy snow, gusty winds, and ice accumulation to western South Dakota and northeastern Wyoming, making travel nearly impossible by Friday morning. The National Weather Service has issued a Winter Storm Warning, with snow totals ranging from 6 to 12 inches in the Black Hills and surrounding areas. Blowing snow and icy conditions are expected to significantly reduce visibility and make secondary roads difficult to navigate throughout the day.

Why it matters

This storm has the potential to severely disrupt travel and daily life across a wide swath of the region, with the possibility of power outages, school and business closures, and dangerous driving conditions. The combination of heavy snow, strong winds, and ice accumulation poses a serious threat to public safety and could isolate some rural communities.

The details

The storm is expected to bring 6 to 12 inches of snow to the Black Hills region, with 7 to 12 inches across the plains and 4 to 6 inches in parts of Crook County, Wyoming. Ice accumulation up to one-tenth inch is also possible. Blowing snow driven by wind gusts up to 35 mph may reduce visibility sharply, especially along Interstate 90 and Highway 85. Rural areas from Faith to Buffalo and Eagle Butte could experience drifting snow and icy patches, making secondary roads difficult to navigate.

  • The Winter Storm Warning begins as early as 3 a.m. Friday in the Black Hills and continues through early Saturday.
  • The worst conditions are expected to occur through the morning commute on Friday.
