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.
  • There may be a few slick spots due to freezing drizzle, but it is not expected to be widespread.

Futurecast 2

  • Late Sunday through Monday morning, snow bands are expected to increase in intensity along and south of I-90.
  • Counties along the Nebraska border will likely see some of the heavier snow bands.
  • Heavy, wet snow will likely transition into light, drier snow as temperatures drop into the 20s.

Futurecast 3

  • Monday afternoon will feature heavy snow bands along the Nebraska border, with a few of those bands creeping up into the Black Hills and locations along I-90 in western South Dakota.
  • 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.

Snow Total

  • A distinct band of heavy snow accumulations are expected stretching from Fall River County ENE through Oglala Lakota County and through the central portion of the state.
  • There will likely be a sharp cutoff of snow accumulations somewhere through Meade, Ziebach or Haakon County.
