A clipper will be moving through the Upper Midwest Monday and leave behind 1 to 5" of powdery fresh snow. Winds will be picking up and lead to blowing snow, low visibility, slick roads and bitter wind chills.
There is very good agreement on snowfall totals with this system and the placement of the heaviest snow -- along and east of the Mississippi. Snow will really wind down Monday morning but some lingering snow showers will be possible near and east of the river.

Winds will be sustained between 10 to 20 mph with gusts around 30 Monday and Tuesday. This will create reduced visibility along with slick roads as the new, fluffy snow gets blown around. This could cause some dangerous travel conditions, especially out in rural areas.
Additionally another shot of cold air will be moving in and the wind will create bitter wind chills. Temperatures will be falling Monday morning and by afternoon temperatures will look like this:
Combined with those strong winds it will feel even colder -
Dangerous wind chills will continue in the range of -15 to -30 Monday and through the day Tuesday. Wind Chill Warnings and Advisories have been posted through Tuesday:
