The subzero temperatures and dangerous wind chills that have gripped Chicagoland all week will gradually start to abate soon. But that won't be on Tuesday. Subzero temperatures, with highs in the low single-digits, will persist throughout the area, along with wind chills again plummeting well below zero. A Wind Chill Warning is in effect for Cook County, along with Chicago's northern and western suburbs, until noon Tuesday. That will then switch to a Wind Chill Advisory until 9 a.m. Wednesday. Chicago's southern suburbs are also under a Wind Chill Advisory now. Temperatures will finally climb back into the teens on Wednesday, with the early forecast for next week showing 30s by Monday.
