Picture 1

  • The National Weather Service in Rapid City has issued a Winter Storm Watch for the following Counties: Fall River, Oglala Lakota, Jackson, Bennett, Todd, Mellette and Tripp County.
  • A Winter Storm Watch means that the timeline and impacts of a potential winter storm are still coming together, but confidence is increasing of an impending event for the area highlighted.

Futurecast 1

  • The timeline so far brings mixed precipitation to the area sometime Sunday afternoon
  • Most areas north of I-90 will see little of this system Sunday.
  • Any rain or sleet will quickly transition over to all snow as temperatures dip below the freezing mark.

  • Winds will begin picking up out of the North and Northwest, bringing gusts up to 35 MPH and wind chill factors in the single digits and close to zero.

Futurecast 4

  • By Monday evening we are transitioning from a mostly snow event to a blowing snow event, with gusty winds driving powdery snow across portions of the Black Hills Region.
  • Snow will continue to be heavy as you push into the central portion of the state Monday evening.
  • Through Tuesday morning, gusty winds will create areas of blowing and drifting snow, before eventually dissipating by Tuesday afternoon and evening.
