Travel will become very difficult with slick and snow covered roads, localized blowing snow, and areas of poor visibility. This includes travel on I-90 and I-94. Difficult travel conditions will likely impact the morning and evening commutes on Friday.

There will be extremely low temperatures with this winter storm. Wind chills are expected to be around -10 below zero over the weekend, and the actual low temperature on Monday night could be -15 below zero.

The National Weather Service also warns of possible "ice jam formation" through early next week, and could cause flooding along rivers and streams. Those who have equipment and livestock near waterways should move them to higher ground, and away from "adjacent low lying areas."

Freeze-up ice jams tend to be short-lived but can result in rapid water rises and localized flooding where they occur. -National Weather Service.
