Sioux Falls, SD
Some of the coldest air since 1997 is coming to KELOLAND. Starting with today, stronger NW winds will go down a bit this afternoon, but areas of blowing and drifting snow will continue in parts of NE SD and SW MN. High temperatures for today have already been reached as temperatures continue to fall through the day.
The worst of the cold will arrive tonight as another arctic front plunges south. Highs tomorrow will stay below zero in both Sioux Falls and Aberdeen and wind chills will drop to -40 in the northeast. Sioux Falls will likely see wind chills in the -30 range much of the afternoon. Winds will be strongest in Rapid City tomorrow at 25-45 mph and areas of light snow. All of this will add up to dangerously cold weather with wind chill warnings in effect for most of KELOLAND.
The wind chill will be even worse by Monday morning as the mercury drops into the 20s below zero East River. We expect widespread -40 to -55 wind chills through the day…with some spots in the northeast close to -60 at times.
The wind chill will remain very cold Tuesday morning, but we expected the mercury to rise above zero late in the day. This warmer trend will continue into Wednesday and Thursday as temperatures return to the teens and 20s for highs. In fact, the new weather data is pointing toward significantly warmer weather by next weekend with widespread 40s and 50s possible in KELOLAND. That’s the light at the end of the tunnel for now.
