Very Slick Commute: Northern Hills, I-90 corridor slick with graupel and sleet

The atmosphere is layered with pockets of warm and cold air, allowing freezing drizzle, sleet, graupel and snow to leave roads slick this morning

  • Sleet, rain, graupel and snow continue for portions of the norther hills and northern foothills this morning.
  • This has resulted in slick roads in Lawrence County and along I-90 through Sturgis and Tilford
  • Some areas of Rapid City are also seeing slick roads as temperatures hover around 32°

  • As soon as you start heading North of Rapid City or North on 385 from 44, you start running into problems.
  • Take it slow, give yourself extra time and don’t assume the roads are just wet – it could turn icy with little time.

  • The snapshot of Sturgis along I-90 shows continued upslope enhancement and a mix of snow, rain and everything else.
  • If you need to commute through the Northern Hills on I-90 this morning, keep these conditions in mind.

  • Temperatures hover right around the freezing mark for most of the area just before 5 AM – so don’t assume roads are just wet.
  • Eventually we could see temperatures reach the high 30s and possibly low 40s outside of the Black Hills – but higher elevations will still hover right around freezing for the most part.

  • A Winter Weather advisory continues this morning until 11 for areas of the Northern Hills and Bear Lodge Mountains.
  • Obviously, this does not mean areas outside of this advisory can’t still see impacts – particularly I-90 between the Wyoming border towards Rapid City.

  • Snow will continue for the outline areas through portions of today, with on and off rain/snow showers in Rapid City and outlying areas.
  • Breezy conditions could also be associated with these showers – making for a cool and slightly blustery day.

Over the next couple hours i’ll be sure to keep this page updated with the latest on this morning’s road conditions and more, stay tuned! -Brant
