Rain continues to in eastern KELOLAND, coming in from the east and southeast due to a low pressure system spinning along the Minnesota/Iowa border. We expect to see amounts around ¾” today and tonight in Sioux Falls and along both side of I-29. Brisk north winds accompany the rainfall, and temperatures are in the 40s under the cloud cover. Sunshine dominates western KELOLAND, where temperatures are in the 60s.
Tonight we’ll see more rain, mainly in SE KELOLAND, with lighter amounts in NE South Dakota. Western South Dakota will be partly cloudy. Lows will be in the 30s, a little warmer where clouds remain.

With partly cloudy skies in the afternoon, temperatures will be near-normal, in the upper 50s to around 60. Western South Dakota may get a few showers in the morning, and a few flakes of snowfall may mix with the showers in Rapid City.
A Winter Storm Warning is posted for the Black Hills, which could get 4-8 inches of snowfall through noon on Friday.
