Enough cold air will roll in with a slow-moving storm to unleash snow in areas where temperatures were in the 40s and 50s F to end this past week.
Despite the prior mild conditions, snow will fall at a fast enough rate for roads to transition from wet to slushy and snow-covered in a matter of minutes.
“People venturing along portions of interstates 25, 29, 70, 80, 90 and 94 may run the risk of getting stuck or encountering dangerous conditions,” AccuWeather Senior Meteorologist Alex Sosnowski said.
A narrow swath from eastern Colorado to Nebraska, southeastern South Dakota, northwestern Iowa, southern Minnesota, north-central Wisconsin and the Upper Peninsula of Michigan will be buried under 6-12 inches of snow, with localized amounts up to 18 inches.
Snowfall rates of 1-2 inches per hour with localized blizzard conditions are possible.
“Even where only light snow falls, increasing winds will cause extensive blowing and drifting snow,” Sosnowski said.
Roadway visibility could be a quarter of a mile or less at the height of the storm.
Denver will pick up enough snow to shovel and plow by the time the storm winds down on Sunday night.
In Minneapolis, snow will pick up throughout Monday and lead to treacherous commutes, especially during the evening hours.
“While the heaviest snow is expected from central Nebraska to the Upper Peninsula of Michigan, a separate area of snow may develop on Monday night and bring a quick couple of inches and slippery travel from around Madison, Wisconsin, to Traverse City, Michigan,” AccuWeather Senior Meteorologist Kristina Pydynowski said.
After receiving rain and even a rumble of thunder from the storm on Monday, enough cold air may sweep into Chicago for the storm to end as a bit of snow on Monday night…..more here
