The storm that began as rain in Chicagoland will change to snow later Thursday, when a wind-driven, rapid freeze-up will lead to slippery travel.
While a severe arctic outbreak and excessive snowfall will not occur in Chicago, it will get cold enough, fast enough with high winds to cause problems.
As a blizzard wallops areas from Omaha to Green Bay, rain and increasing wind will affect the Chicago area from into Thursday afternoon. However, a sharp change to cold weather with high winds and snow is forecast to occur during the Thursday evening rush hour.
Bursts of snow will leave between 1 and 3 inches around Chicago. It is possible blizzard conditions develop for a brief time Thursday evening. A layer of ice and slush that forms on untreated surfaces can make for very slippery and dangerous travel conditions.
According to Chief Meteorologists Elliot Abrams, "If folks want to see a foot of snow they may only have to drive 80 miles to the west in the blizzard Thursday over northwestern Illinois or 80 miles to the east in lake-effect over northwest Indiana Friday."
Motorists should expect delays and very slippery conditions to spread eastward Thursday night.
Flight delays are possible, not only from the period of snow and icy conditions that can occur, but also from the high northwest wind gusts that can range between 50 and 70 mph.

There is the potential for power outages, downed trees and minor property damage.
The plunging temperatures, high winds and snow squalls will slice eastward over Indiana, Ohio and Michigan Thursday night, potentially resulting in a similar rapid freeze-up on untreated surfaces.
In addition, the combination of heavy lake-effect snow and near hurricane-force wind gusts will make for whiteout conditions in the snow belts of northern Indiana, western Michigan and northeastern Ohio through Friday.
Strong winds will remain a problem Friday in Chicago, Milwaukee, Detroit, Indianapolis, Cincinnati, Cleveland, Buffalo and Pittsburgh.
Another powerful storm could affect the Midwest around the same time next week (Dec. 26-27).
As the death toll climbs early this week, thunderstorms will continue to disrupt rescue and recovery efforts across the Kathmandu Valley.
Severe thunderstorms and heavy rain will continue to push eastward across the upper Gulf Coast and re-fire farther west in Texas into Monday night.
Severe storms pummeled parts of eastern Texas Sunday into early Monday morning with softball-sized hail, damaging winds and tornadoes.
Temperatures are starting off on a cool note before milder air moves in for the middle of the week in much of the Northeast.
Bouts of heavy rain will once again visit the Southeast this week, bringing the threat of flooding and travel delays.
