Morning Fog Gives Way to Sunny Weekend: Light snow expected Sunday evening

Patchy freezing fog and low visibility will give way to a sunny weekend, with light snow accumulations expected Sunday night

  • Areas of freezing fog and low visibility are patchy this morning, with the I-90 corridor between Sturgis and Rapid City seeing some very dense fog in the early morning hours.
  • Things will clear up nicely late this morning and afternoon, with temperatures reaching the 40s and abundant sunshine.

  • A tower cam shot from Tilford shows some pretty good fog in that region.
  • Slow down, and while its still dark out keep your brights turned OFF.

  • Friday night is expected to be clear with temperatures in the 30s, with a nice recovery on Saturday with 40s and 50s across the region and partly cloudy skies.
  • Westerly winds along the eastern foothills should keep things warmer than the surrounding areas, where 40s are more likely for high temperatures.

  • The first part of Sunday looks dry, but temperatures won’t recover into the 40s like we’ve been used to – it may struggle to even reach the mid 30s.
  • A more potent cold front will push Southward, dropping temperatures into the teens by Sunday evening and bringing the chance for snow across the region.

  • So far it looks like snow will be moving through the Northeast Wyoming, Northwest South Dakota and the Northern Hills between 3-6 PM
  • Areas to the South and East of the Black Hills, including Rapid City, may not see a snowflake until after dark.
  • Some of this also might start out as a mix, rather than straight snow.

  • By 10 PM – 2 AM light to moderate snow bands will be crossing most of our region, with some areas seeing slick roads and low visibility.
  • Most snow activity will be ending by around 3 – 6 AM, pushing Southeast of our area and leaving behind colder temperatures for Monday morning in the single digits and teens.

  • It would seem areas Northeast of the Black hills towards North Dakota could see some light to moderate accumulations – around 2″-4″ in places like Harding and Perkins County.
  • Areas South may struggle to see anything about 1″-3″, including the Black Hills and Rapid City.
  • There could be travel impacts with slick roads and icy bridges – but overall this is expecting to be a low impact system.

  • Monday through about Thursday of next week looks to be colder than normal, with temperatures in the 20s and 30s for highs and possibly single digits overnight.
  • Most of the arctic air will miss us to our East, so areas of Faith, Philip, Kadoka and East River will see generally colder temperatures and should be ready to bundle up for negatives and single digits.
  • The Black Hills and areas West will certainly be colder than this last week, but we aren’t expecting the polar plunge that some areas East of us could receive.


Next week looks cold and unsettled, but nothing significant so far on the long range models. Northwest flow looks to persist going into the next week and a half, which is a recipe for quick moving cold snaps and bursts of light accumulations here or there. We’ll monitor those conditions closely as we approach the holidays as we know travel plans are important (Thanksgiving anyone?). Be safe with the low visibility this morning, as some of that fog you’re driving through could be freezing fog! Thanks for checking in. – Brant
