We have been melting snow today, with all but the NE corner of South Dakota above-normal temperature-wise, in the 30s and 40s. Rapid City has seen the upper 50s. There are only some high passing clouds coming through, so skies are mostly sunny.
Tonight skies will be mostly clear, although some patchy fog may form due to the snow melt and light winds. It will be a mild night, with lows in the teens to 20s – not too far from normal high temperatures this time of year.
Tomorrow will be mostly sunny across KELOLAND – except for northeastern South Dakota, where it will be partly cloudy. Temperatures will again be mild, in the 30s and 40s. Aberdeen and the northeast will be a little cooler, in the mid 20s. Rapid City will be in the mid 50s. Winds across the area will be light, generally less than ten miles per hour.
On Sunday – big game day – it will continue to be very warm. Sioux Falls and SE KELOLAND will warm into the low 40s – so warm that we could see some Sunday evening rain showers. We’ll be in the 20s in the north to the 30s in central South Dakota. An area of snow will develop in western South Dakota during the day and move east by Sunday night.
Strong north winds will drive colder air our way on Monday, with rain changing to snow in Sioux Falls and the SE – and just plain snow in the north and west. With the brisk winds, highs will only be in the single digits in the north to the teens in the south. It looks like a “couple inch” type of snow for Sunday night and Monday. Most of the snow will occur during the morning hours.
We’ll have additional chances of snow on Tuesday and Wednesday and even into Thursday morning. But it appears that any snows that form in the cold air will be light. But arctic air will also make a return, so we’ll see subzero mornings, with single digits to teens during the days. While the air will be cold, it won’t be as cold as what we’ve had this week.
The center of that cold pool will come through on Thursday and Friday, with teens below in the morning and barely above zero at best Thursday and Friday afternoon. But after that, we expect temperatures to moderate through the following weekend and beyond.
