Winter Weather Advisories posted for portions of the Black Hills

Light to moderate snow accumulations are expected this evening across portions of the I-90 corridor through northeast Wyoming and the Black Hills

  • A Winter Weather Advisory has been issued by the National Weather Service for portions of Meade, Lawrence, Butte, Weston and Crook County.
  • This Advisory starts at 9 PM this evening and goes until 6 AM Friday, looking at 2″-5″ inches of snow during that time.

  • An additional Winter Weather Advisory has been issued for portions of Campbell and Crook County in Wyoming.
  • This will be for slightly less amount of 1″-4″ and the possibility of snow covered roads.

  • By 9 PM this evening, a distinct band of snow is expected to set up West to East across Northeastern Wyoming and the northern Black Hills – following the I-90 corridor.
  • Some of these snow bands could be heavy at times, with low visibility and slick road conditions – use caution.

  • This energy will eventually push into Western South Dakota by the early morning hours of Friday.
  • Friday morning commute could have snow bands along the I-90 corridor between Spearfish and Rapid City, heading South along SD-79 towards the Nebraska border.

  • By late morning, most snow bands will have pushed out of the region, save for a few stubborn spots here or there.
  • Friday evening’s forecast calls for much cooler and breezy conditions – but mostly clear skies otherwise.

  • Here are some preliminary amounts that can be generally expected across the Black Hills region by Friday morning.
  • These amounts could still shift around – so don’t take these as gospel necessarily.
  • Regardless of where snow accumulations might shift, we aren’t expecting large amounts overall – the exception being a few heavy pockets in the northern Hills where upslope enhancement could play a few tricks.

We’ll be sure you keep you updated on any further developments! -NC1 Weather Team
