Winter Storm will Impact Travel Thru Tuesday Evening

A powerful winter storm system will bring a significant, long-duration snowfall event to much of South Dakota, Minnesota, Iowa and Nebraska today and tomorrow. With 6 to 10 or more inches of snow likely over the next couple of days and wind gusts to 20 or 25 mph tomorrow into tomorrow night, travel will be impacted. A Winter Storm Warning is in effect for much of our region – including the Sioux Falls metro area – through Tuesday evening.

The storm will begin with areas of light freezing drizzle this morning. That will quickly change to snow that will become heavy at times by later this morning and will continue through the afternoon. Our heaviest snow will fall during the day today with 4 to 6 inches possible today alone. Snow that falls today will be relatively wet and heavy but will become lighter and fluffier as temperatures drop slightly this afternoon. Snow, while a bight lighter, will continue to fall through tonight and tomorrow with an additional 2 to 4 inches possible through tomorrow evening.

The wind will be relatively light both today and tonight, however, it will increase tomorrow. Gusts to 25 mph are possible by tomorrow afternoon through tomorrow evening and that will create areas of blowing snow at times, especially in rural areas.

First Winter Storm of the Season Friday

I have two big things to talk about this morning. First, the cold and windy weather that we will experience today. Second, and most would say a bigger deal, the potential for a winter storm that will impact areas along and south of I-90 tomorrow.

I’ll start with today. The big takeaway in regards to today is BUNDLE UP because it is not going to be pleasant at all. Today will be windy, cold and blustery all day. Definitely the coldest weather we’ve had to deal with so far this season. High temperatures will only reach the 30s with strong westerly wind gusts to 50+ mph. A Wind Advisory is in effect for most of South Dakota, Minnesota, Iowa and eastern Nebraska today. Throw the wind and the cold together and it’s gonna feel like temps are in the upper teens to low 20s.

Now the snow: A fairly powerful system that rolled across the Pacific Northwest yesterday will move into our neck of the woods and bring accumulating snow to locations along and south of I-90 during the day tomorrow. As of right now, I think that there will be a band of 5 to 8 inches of accumulation, however, at this point there is a lot of uncertainty as to where that heaviest snow band will be. Our latest data suggests that the heaviest snow will fall south of Sioux Falls, somewhere between US Highway 18 and the Missouri River. If that scenario pans out, Sioux Falls and the I-90 corridor would receive about 2 to 4 inches. That said, our model data has been very inconsistent with the track of the storm, so the snow accumulation forecast will likely change a bit over the next 24 hours. One thing that is clear, the wind will not be a significant factor with this system. The wind should hold at at about 5 to 15 mph through the duration of this storm, perhaps increasing to 10-20 mph for a short while on Friday evening.
