Cold air will slowly retreat tonight due to increasing southerly winds of fifteen to twenty-five miles per hour. Lows of single digits and teens below zero will be likely in eastern South Dakota early tonight, but above zero temps will be common in much of KELOLAND by sunrise.
The strong south winds will continue for tomorrow with some areas of Minnesota and Iowa recording gusts to the thirty and forty mile per hour range. Areas of blowing snow will be possible in eastern KELOLAND. Along with the south winds, temperatures will be warmer with highs in the twenties to near thirty in eastern South Dakota to the middle thirties in Pierre and near fifty in Rapid City.
A cold front will quickly sweep through on Friday night to bring in colder air for the weekend. Along with the colder air, flurries and light snow showers will be possible Friday night. Any snow that falls will stay less than a half inch.
Saturday and Sunday will remain cold with highs in the single digits and teens for central and eastern South Dakota; twenties can be expected in the west. This is ahead of the main cold air for Monday. Temps will fall to the teens and twenties below for Monday morning with highs in the single digits and teens below zero Monday afternoon.
After Monday, temperatures will slowly warm above zero for highs with lows in the single digits and teens below zero.
