Two rounds of snow and the coldest air of the season are headed our way this weekend. Here's the scoop:
The First Round:
The first round of snow will roll in late tonight and continue through most of the day tomorrow. I expect about 1-2 inches in Sioux Falls with 2-4 inches possible along the US Highway 14 corridor. Wind will not be an issue with this round. It will be the type that falls and sticks to roads and sidewalks, so slippery roads will be a problem throughout the day tomorrow.
Hour by Hour Forecast:
Round two will kick in late Saturday and continue through Sunday. This event is still several days away, however, as of right now it looks as though we could see 2 to 4 inches of accumulation in places. Because it will be colder, the snow will be fluffier and more easily blown. There will be some wind late Sunday, so blowing snow could be an issue.
Here's our preliminary forecast for round two. There will likely be changes to this over the next couple of days. Stay tuned.
In addition to the snow, we're also expecting the coldest air of the season by early next week. On Monday morning, actual lows will be in low the single digits in Sioux Falls and across the tri-state area, the single digits below zero across northern South Dakota. Wind chill will be well below zero for everyone.
