Icy Mix to Coat Roads From St. Louis to Chicago Tonight
A potent storm lifting through the Ohio Valley tonight will generate everything from snow to severe weather with the wintry precipitation battle ground lying from St. Louis to Chicago tonight.
After an outbreak of severe weather over the Mississippi Valley, the same storm will spread precipitation northward into the Ohio Valley and Great Lakes tonight.
An icy mix will develop late this afternoon into tonight from Springfield and St. Louis, Mo. through Chicago, Ill. and Kalamazoo, Mich.
AccuWeather.com meteorologists are concerned that a prolonged period of sleet and freezing rain across parts of this corridor can lead to dangerous road conditions.
According to AccuWeather.com Expert Senior Meteorologist Brian Wimer, "The potential exists for someone around Chicago or in the suburbs to pick up as much as an inch of sleet."
Not only will the icy conditions cause problems initially, but the precipitation is then expected to changeover to a period of snow late tonight which could accumulate up to an inch or so on top of whatever ice ends up falling.
Farther to the north and west, all snow will fall from Kansas City and Columbia, Mo. through Rockford, Ill. and Milwaukee, Wisc.
Across this region, upwards of 1-3 inches of snow can accumulate tonight into Sunday morning, leading to snow covered roadways and slick travel conditions, especially with the heaviest falling during the nighttime hours.
Travel late this afternoon into tonight will become slow and difficult across Interstate 70 from Kansas City to St. Louis. Also, Interstate 44 from Springfield to St. Louis.
Farther north, Interstate 55 from Springfield, Ill. to Chicago will become slick after sunset.
Stay tuned to AccuWeather.com for the latest information on the winter weather heading through the central part of the country.
Most of the wintry precipitation will taper off by Sunday morning, but sharply colder temperatures will move in behind this system for the end of the weekend into a good part of next week.
