Wednesday Speed Bump: Snow/Rain showers, then warming trend

Snow will move in from northeastern Wyoming into the Black Hills, transitioning to mostly rain for South Dakota

  • Showers will start moving in from Northeastern Wyoming this morning into this afternoon, with temperatures starting out in the 30s and 40s.
  • Breezy northwesterly winds will accompany the advancing cold front and drop temperatures into the lower 30s – so not terribly cold but enough where you’ll want to dress for slightly cooler weather this morning.

  • Around 10 AM areas of the Northern Hills, Bear Lodge Mountains and I-90 corridor between Sundance and Sturgis could see a few bursts of rain/snow activity.
  • This is when we expect to receive most accumulations, if any at all. Most areas of the South Dakota Plains will be hard pressed to see much snow activity.

  • By Wednesday evening we are in the 20s and 30s, with most activity pushing off East.
  • Mostly clear skies and breezy Northwesterly winds will require a good jacket for the evening.

  • Not overall impressive numbers for accumulations, but if you like a passing snow showers outside your window this is your kind of day.
  • Portions of the Black Hills including Deerfield, Cheyenne Crossing, Spearfish Canyon and the Bear Lodge Mountains could see a 1″-2″ mark – but overall low accumulations are expected.
  • Most areas of South Dakota could have some light accumulations on grassy surfaces and vegetation, as the ground is too warm for larger amounts.
  • Bridges and overpasses could still be slick, so just be vigilant.

  • By Thursday temperatures recover in the 30s and 40s, and a general warming trend will take place going into the weekend.
  • A slight chance of some flurries in Northeastern Wyoming from Thursday night into Friday will be the only action we get until next week.


You guys know the drill, make sure you are driving the conditions! Could have a few slick roads in the Northern Hills and out towards Northeastern Wyoming. Things looking very nice for the weekend though! Make sure to enjoy it. February is generally our colder time of the year and we may not get many opportunities to enjoy mid 50s…

Happy 77th Anniversary to the world record chinook wind event in Separfish! 49° temperature change in less than 2 minutes… i’d say that’s pretty good wouldn’t you say?

Be safe out there! -Brant
