A wintry mix Wednesday, highs in the 30s

CHICAGO — An Ice Storm Warning has been issued for much of the Chicago area that will impact at least a portion of the evening commute Tuesday into early Wednesday morning.

Freezing rain possibly mixed with sleet and wet snow early in the process will overspread most of the Chicago area Tuesday night into early Wednesday morning, beginning in the westernmost sections later this afternoon. Ice accumulations of a quarter-inch or more will make travel or outdoor activity extremely dangerous, especially on untreated surfaces. Accumulation of ice will likely damage trees and cause downed power lines leading to power outages.

Temperatures will be warm enough in central Illinois to have that area experience all rain, but readings will hover below freezing (25 to 30-degrees) most of the area north of roughly a Pontiac to Kankakee to Valparaiso line. A Winter Weather Advisory for Freezing Rain (purple-shaded area on the headlined map) is in effect to show a transition from the warmer rain area to the south and the colder freezing rain/sleet area to the north. Rain should end from the west early Wednesday morning.
