1st accumulating snowfall of season to fall in parts of midwestern US through Friday

A storm will lay a swath of snow and slick travel across the Midwest through Friday, with some areas expected to pick up their first accumulating snowfall of the season.
Enough snow is expected to fall to create slick conditions for drivers and make snow shoveling necessary in some communities.
After whitening Kansas City, Missouri, and bringing the first snowflakes of the season to St. Louis on Thursday and Thursday night, the storm will continue to track northeastward into the Great Lakes region to end the week.
Into Friday afternoon, the core of the snow is expected to sweep through northern Missouri into southeastern Iowa and northern and central Illinois, including Chicago.
“With the snow coming when low temperatures are at or below freezing, snow will likely stick to roads, especially bridges and overpasses,” said AccuWeather Meteorologist Ryan Adamson.
“This will be the first measurable snow (0.1 of an inch or more) of the season in some areas, so drivers may not yet be acclimated to driving in winter conditions,” Adamson noted.
If you haven’t done so already, make sure your vehicle is ready for the cold and snow.
Madison, Milwaukee and Green Bay, Wisconsin; and Chicago are among the cities that can receive their first measurable snow of the season with this event, as a coating to an inch or two of snow is expected to accumulate.
These cities received their first snowflakes of the season in October, but amounts were under 0.1 of an inch.
“The snow will lift northward across Michigan on Friday afternoon, with as much as 3-6 inches expected in the northern Lower Peninsula and the Upper Peninsula,” Adamson said.
Up to a foot of snow could fall where snow bands pivot around on the back side of the storm and are enhanced by lakes Michigan and Superior.

A separate area of snow showers will sweep out of the northern Plains and may briefly whiten Iowa at the end of the week, but this batch of snow will be more of a nuisance compared to what will be ongoing in Michigan.
Where snow falls lightly during the day, accumulations will be mainly on grassy and elevated surfaces, as opposed to roadways. However, any heavier burst of snow can quickly create a slippery covering on untreated paved surfaces and heighten the risk of vehicle spinouts.
Snow will exit Chicagoland in time for Friday afternoon and evening commuters, but the gusty winds will make for turbulent takeoffs and landings for airline passengers out of O’Hare and Midway.
While calmer weather will move into much of the region on Saturday, lake-effect snow will continue to stream off of lakes Michigan and Superior.
The lake-effect snow machine will also be in full force in the Northeast at the start of the weekend.
