What a gorgeous November day! Highs got close to, or above 60° along Interstate 90 and most of us got back close to normal. It’s been the first really quiet day in quite awhile and we expect a calm evening, too. There is a trough coming in from Montana tonight that will bear watching. The center of it will stay north of KELOLAND and the big change will be the wind tomorrow and the sharp cool-down by Monday.
The clouds coming from that will help slow down a quick chill early this evening. After midnight, we’re not expecting much more of a cool-down.
The strongest core of winds tomorrow will be just ahead of the encroaching cold front. That will warm us up in eastern KELOLAND BUT it will FEEL colder. We’ll keep fair skies in places for much of the day, despite the front coming in. There is very limited moisture behind the front but limited chances at a snowy mix come to the Hills early Monday. This thin band moves east into Aberdeen and Pierre late in the day but should remain light.
The second wave of the storm arrives Tuesday, now a touch farther west into SD. This looks more on the snowy side than it has in past days, but the moisture itself is trending downwards. Even Sioux Falls could see some snow if things continue to get colder. By Wednesday, much of the moisture is pushing east of the area.
The rest of the workweek will be cool, especially in the mornings. There are a few subtle signs of a weak warming trend next weekend.
