After Monday's brief break from below-average temperatures, winter weather returns tonight with one to three inches of snow possible.
After 10 p.m. rain will transition into snow across much of northern Illinois. Snow could become heavy at times, and increasing wind speeds may lead to blowing or drifting snow overnight, according to the National Weather Service.
Tonight's low is expected to fall to 21 degrees, with wind gusts up to 35 mph. The temperature will continue to drop to 19 degrees by 9 a.m. Wednesday, and wind gusts may reach 30 mph, the weather service said.
Snow will linger through Wednesday morning, with continued blowing snow expected across much of the area, the weather service said.
Wednesday night's low will be around 5 degrees, with wind chills values as low as -4.
There is also an increased risk of localized flooding due to ice jams on area streams.
