Sioux Falls, SD
It’s a very cold day in KELOLAND once again, with morning lows dropping down into the teens and 20s below zero. Aberdeen dropping to -27 during the 5 a.m. hour. With the cold start, temperatures will be slow to rise during the day. Highs will be a couple of degrees either side of zero in most areas with light winds.
Developing clouds in the mid to late afternoon will lead to light snow tonight and tomorrow in much of KELOLAND. This will not be a heavy snow, but a broad 1-3” snow looks likely, with the heaviest amounts forecast in NW IA. Some local amounts could top 4” south of Sioux Falls considering the fluffy nature of the snowfall.
Look for another drop in temperatures on Monday with wind chills returning to -15 to -30. The other story late Monday into Tuesday will be stronger NW winds. We are still monitoring the strength of the wind, but areas of NE South Dakota and western MN may see gusts to 40mph. That would create some blowing snow, so be advised of that and monitor further forecasts later today and tomorrow.
The cold snap will continue into early next week, although daytime highs should be a little warmer. We should see a better warming trend by Thursday or Friday with highs reaching back into the teens and 20s East River, with some upper 30s again in the far west.
