The storm responsible for a swath of heavy snow from the Rockies to the North Central states early this week will draw in much colder air and gusty winds.
The storm and expanding cold air will disrupt travel and other daily activities through midweek.
Through Tuesday, the storm will bring enough snow to shovel and plow in Minneapolis, Wausau, Wisconsin, and Marquette, Michigan, and in other towns and open country in between.
The heaviest snow will fall over central Minnesota, northern and western Wisconsin and the Upper Peninsula of Michigan through Tuesday.
A broad area of 6- to 12-inch snowfall is forecast from central Minnesota to northern Michigan with locally 18 inches to fall within this swath.
Major highways that will be impacted by the storm include interstates 35, 90 and 94.
The combination of snow, wind and plunging temperatures from Wyoming and Colorado to northern Michigan will make for dangerous travel into midweek. Road conditions will transition from wet and slushy to snow-covered and icy.
Winds in this area during and following the storm will gust between 20 and 40 mph. The gusty winds will cause significant blowing and drifting of the snow on the ground in open areas. This could make it even more difficult for crews trying to clear roadways.

AccuWeather MinuteCast®--Know When Snow Will Arrive
Over the Upper Midwest, temperatures during much of the storm will hover in the 20s but will plummet into the teens at night. AccuWeather RealFeel® Temperatures will plunge to near and below zero in the immediate wake of the storm.
Sidewalks and road surfaces with patches of snow or slush will rapidly freeze up.
The storm will spare Chicago, Indianapolis and Detroit, but a small amount of snow and a freeze-up can make some surfaces slippery in Omaha, Nebraska; Des Moines, Iowa; Madison, Wisconsin; and Lansing, Michigan.
The brief period of snow will affect eastern Nebraska and parts of central Iowa Monday night, southern Wisconsin on Tuesday and part of central Lower Michigan Tuesday evening.
The storm has left a swath of snow ranging from a coating to nearly 8 inches over much of South Dakota. Temperatures have plunged into the single digits and teens in parts of Montana, Wyoming and North Dakota as of Monday morning.
The most severe cold in the wake of the storm will continue to take aim at the northern Rockies and northern Plains but will plunge farther south over the Central states.
The bitterly cold plunge will send temperatures to the single digits and below zero in some locations of South Dakota, Nebraska and Colorado.
RealFeel Temperatures will plunge well below zero from the northern and central Rockies to the northern Plains.
Along the Front Range of the Rockies, the action of cold air blowing uphill will squeeze out more moisture in the form of snow, while the parent storm moves away and blasts the Upper Midwest.
Snow, slippery travel and plummeting temperatures will not spare Denver in this event into Wednesday.
If you must travel, make sure you and your vehicle are prepared for snow and cold.
In addition to roads becoming rapidly snow-covered and icy, life-threatening temperatures are possible for those not properly dressed and become stuck on the road in the open country from the central and northern Rockies to part of the Upper Midwest.
