The Fox Valley is shivering from an icy cold blast Thursday morning that comes on the back of a sizable snowstorm.
The storm dumped about 7 inches of snow by Wednesday afternoon, causing dozens of spinouts and crashes in the area and more than 550 canceled flights.
Then temperatures plummeted overnight to about 5 below zero, with wind chills below 20 below zero.
A wind chill warning is in effect until 10 a.m. Thursday for McHenry, Kane and Kendall counties, the National Weather Service said.
Thursday will stay cold, with highs reaching 6 to 10 above, with a wind chill of 10 to 20 below, the weather service said.
Another round of snow is possible Saturday and Sunday night.
The latest round of snow and cold follows a brutal January that ranked as the area’s third snowiest and 10th coldest on record, the weather service said. Residents suffered through 33.7 inches of snow and a frigid average temperature of 15.7 degrees, more than 8 degrees below normal.
