Midwest snowstorm to impact drivers heading into 2021 (with forecast video)

A strong winter storm will likely slow down supply chains, freight movement and business operations this week across several Midwest states.

The combination of snow, ice and gusty winds will cause mostly minor to moderate disruptions to surface and air transportation from the Central Plains to portions of the Great Lakes. Major cities within the potential impact zone include Kansas City, Missouri; Omaha, Nebraska; Des Moines, Iowa; and Milwaukee and Green Bay, Wisconsin. Major interstates within this zone include I-80, I-90, I-35, I-39 and I-43.

A complex storm system in the western U.S. will slowly move across the central U.S. Tuesday through early Thursday (New Year’s Eve), producing moderate snowfall and gusty winds, as well as some sleet and ice.

Ice buildup of a tenth to two-tenths of an inch is possible, especially in the southern half of the potential impact zone within Nebraska, Kansas, northern Missouri and northwestern Illinois. Snow accumulations will reach 5 to 10 inches in many areas within the zone, with the highest totals likely in Iowa and southern Wisconsin. Stronger winds — gusts ranging from 30 to 40 mph — will cause significant blowing snow and occasional whiteout conditions.
