Areas of snow will move through KELOLAND with winds picking up speed through the day, leading to areas of blowing snow. The heaviest snowfall will be in the northeast corner of SD where a winter weather advisory has been posted until 3pm. 1-3” will be possible in Sisseton, Britton, and Webster. Otherwise, temps will be falling this afternoon in many areas as winds increase behind this clipper system. The strongest winds will be in western SD where gusts will be near 50mph. Areas of blowing snow can be expected, so travelers should be alert to localized problems.
Temperatures will be much colder tomorrow with highs only in the mid teens in the east, with readings near 30 in Rapid City. The cooler weather will be temporary in the west as a warm front develops and heads east through Saturday. We’ll likely see a big contrast in temperatures this weekend with highs near 50 in Rapid City, with mid 20s in Aberdeen. Pierre and Sioux Falls will be in between in the mid 30s to around 40 by Sunday.
Next week is looking very interesting. By Thursday, the long-range data is suggesting a powerful storm moving into the plains. That track can certainly change, but most of the data actually agrees on a storm affecting KELOLAND. Stay tuned, I’m sure we’ll more on this later today.
