Clouds will thicken this evening and tonight with developing light snow in western, central, and northeast South Dakota. The snow amounts will stay less than an inch. Temperatures will fall to the single digits and teens below zero early tonight in eastern South Dakota, and then slowly warm. I wouldn’t be surprised to see many locations in the single digits above zero by sunrise.
Clouds will remain for Monday with scattered light snow likely. While many locations will have snow amounts remaining below an inch, parts of northeast South Dakota, from Watertown to Aberdeen and northeast will have a chance for an inch or two. Highs will be in the teens and twenties for much of the area.
Tuesday will bring a better chance for light snow. The accumulations will be a little more than Monday with amounts of one to three inches possible for just about everyone. Highs on Tuesday will be in the single digits and teens.
New Year’s Day will be cold with highs in the single digits and teens. There’s still a chance for snow that day, and then we’ll have dry skies until Sunday. Temperatures will slowly warm beyond Wednesday.
