Forecasters say Illinois is poised to see more frigid weather. And lake-effect snow will hit some of the Chicago area hard.
National Weather Service forecasters in the Chicago area say northern Illinois will see overnight temperatures Monday into Tuesday as low as 4 below zero. Wind chills are forecast at between 15 and 25 degrees below zero with winds of up to 20 mph.
A wind chill advisory is in effect between 3 and 10 a.m. Tuesday for Lake, Kane and McHenry counties. The weather service said wind chills could dip as low as 25 below zero.
"Frost bite and hypothermia can occur in a matter of minutes," the weather service says.
Then the weather service has issued a lake-effect snow warning for eastern Cook County and Lake County, Ind. As much as 12 inches of snow is expected to fall starting late this evening. A lake-effect snow advisory is in effect for Will County.
"The band of heavy snow is expected to be only less than 10 miles wide," the weather service says.
Within that band, as much as 2 inches of snow per hour could fall, limiting visibility.
The National Weather Service in Lincoln, in central Illinois, has issued wind chill advisories for areas around Galesburg, Pekin and Peoria. Wind chill advisories also have been issued for northern Illinois.
The cold weather is expected to stretch through Thursday.
