Winds are diminishing from the fierce gusts we had last night. It will still be “wind chilly” early in the day, mainly due to the arctic air mass overhead. Unfortunately, that cold air will be with us for a few days.
Highs in eastern South Dakota are unlikely to escape subzero today. We’re forecasting a maximum of -3 in Sioux Falls and Aberdeen, despite abundant sunshine.
Clouds will start to move back in tonight, which will again be in the low teens below zero in eastern KELOLAND. Rapid City will be warmer, around 12 for a low, with a chance of light snow.
Skies will be mostly cloudy on Monday, with a slight chance of light snow (mainly north and west of Sioux Falls). Temps will be a little milder, in the single digits to teens East River, while Rapid City basks in 33 degrees.
We have a chance of light snow both Tuesday and Wednesday (New Year’s Day). Not much moisture, but a decent chance we’ll see some snowflakes. Temperatures will probably remain in the single digits for highs East River.
Then things moderate for the end of the week. In fact, temperatures will approach early January normals Friday and Saturday.
