CHICAGO (CBS) — Chicago’s weather roller coaster will take another tumble starting tomorrow; with temperatures that will be more than 20 degrees colder, and a mix of sleet and freezing rain coming through.

Temperatures have been above freezing for more than two days, reaching the 50s on Monday, after Chicago endured more than two days of temperatures below zero last week, but the recent mild stretch comes to an end overnight.

By Tuesday morning, temperatures will be in the low 20s, and won’t get above about 30 the rest of the day. It will be mostly cloudy and dry during the day, but around sunset, a mix of sleet and freezing rain will develop.

The National Weather Service has issued a winter weather advisory from 6 p.m. Tuesday through 6 a.m. Wednesday for most of northeastern and north central Illinois, due to the sleet and freezing rain.
