Storm Center Update - Sunday PM

An Arctic cold blast has already started, and will be most noticeable through the workweek. We'll start on MLK Day with snow West River, mostly during the daytime hours. The bulk stays along I-90, and the heaviest looks to be in the Black Hills. By later in the afternoon, Pierre looks to pick up some snow. The southeast will be impacted tomorrow night but mostly early on Tuesday morning. It will be tougher for Aberdeen to fight off drier air to get some snow.

This system will not be a drought buster. Many areas will see between 1-2" of snow. Some locally heavier totals are possible around Pierre and the Black Hills.
The areas that do get snow will be even colder during the week. Highs will not break 20 on many days, though Thursday looks to be one of the coldest. Lows below zero are something to watch for, especially the farther north you go.

We have another chance for light snowfall late Wednesday/early Thursday for Sioux Falls and Pierre. Signs are pointing to warmer temperatures returning in time for next weekend.
