CHICAGO -- An Ice Storm Warning (scarlet-shaded area on the headlined map) for freezing rain mixed with sleet and snow is in effect until mid-morning for a good portion of the Chicago area along and north of Interstate-80.
At the same time, additional snow accumulation is expected today and tonight in northern counties bordering Wisconsin. A Wind Advisory kicks-in beginning at 2PM CST this Tuesday afternoon continuing well past midnight tonight.
Extremely dangerous conditions for outdoor activities and travel will exist area-wide. The Tuesday morning commute will be slowed by slick roads and snow-covered highways, and movement outdoors made extremely hazardous due to glaze covering a good portion of northeast Illinois into northwest Indiana.
Several schools across the area are closed or opening late due to the hazardous conditions.
Metra Electric train service has been suspended until further notice. Metra suggest customers seek alternate transportation at this time. South Shore Line train service has also been suspended due to weather.
As of 6 a.m., ComEd is reporting more than 7,000 power outages in Cook County alone. More outages expected.
Temperatures will hover around 32-degrees this morning, then fall into the 20s this afternoon, so not much melting will go on – thus the afternoon/evening commute will also be slowed.
The center of an intensifying low pressure system will track south of Chicago into Lower Michigan Tuesday, heading into Ontario Canada later Tuesday night. A wintry mix of freezing rain/sleet and snow will lay out to the north of the low-pressure track, covering the Chicago area.
A Wind Advisory is issued for the entire Chicago area later Tuesday/Tuesday night as the storm center pulls away, strengthening west to northwest winds eventually gusting 40 mph or higher will direct much colder air into our area, changing all precipitation to snow showers and potentially causing widespread ice-laden tree damage and subsequent power outages. As you go north, storm total snowfall looks to gradually increase from 1 to 2-inches along the Interstate-80 corridor to the 4 to 8-inches far north.
