Weather officials are urging residents to avoid unnecessary travel to rural and open areas on Wednesday morning as near whiteout conditions are expected due to gusty winds and blowing snow.
The National Weather Service has issued a winter weather advisory for most of northern Illinois and parts of northwest Indiana, as wind gusts greater than 40 miles per hour could cause blowing snow and blowing snow in the area until Wednesday evening.
The alert described “near ground blizzard” conditions as likely with winds, which will emerge from the west and impact north-south routes.
The advisory will begin at 9 p.m. for McHenry, Lake, DeKalb and Kane counties in Illinois, and expire at 3 p.m. Wednesday. The advisory will begin concurrently in LaSalle, Kendall and Grundy counties, but will not expire until 6 p.m. Wednesday.
In DuPage, Cook and Will counties, as well as Lake and Porter counties in Indiana, the advisory will take effect Wednesday at 3 a.m. and expire at 6 p.m.
In Kankakee County, Illinois, as well as Newton and Jasper Counties in Indiana, a wind advisory will be in effect during these hours.
Strong winds are expected to develop from the south on Tuesday evening, initially affecting east-west routes, but these winds will later shift, affecting north-south routes during the term of the advisory, forecasters will shift later.
These wind gusts could exceed 40 to 50 miles per hour in parts of the council area, causing dangerous travel conditions.
Snow showers on Wednesday morning could only exacerbate the problems, potentially affecting morning commutes and causing dangerous travel conditions in the region.
NWS forecasters are urging residents to consider postponing unnecessary trips to rural and outlying areas.
Another challenge will be to bring temperatures down quickly, as wind chills are likely to fall below zero Wednesday at dawn. High temperatures for the remainder of the work week are not expected to get out of teens, with wind chills near or below zero until Saturday.
