The Chicago area is bracing for multiple rounds of lake-effect snow on Friday, potentially disrupting both morning and evening commutes. A winter weather advisory has been issued for Lake, DuPage, and Cook counties through Friday afternoon, according to the National Weather Service.
Lake-Effect Snow Threat
The first wave of lake-effect snow is expected to impact northeastern Illinois Friday morning. Areas closest to Lake Michigan are likely to experience the most significant impacts, though slick road conditions and reduced visibility could extend into the western and southern suburbs.
Later in the day, a winter storm watch will be in effect for central and southern Cook County. Snowfall rates could reach 1-to-2 inches per hour, potentially accumulating 4-to-6 inches in parts of Chicago and its immediate southern suburbs before the bands shift eastward toward Indiana.
North winds are forecast to drive intense lake-effect snow bands into northwest Indiana, with the possibility of these bands extending along the Illinois-Indiana border. The heaviest snowfall is expected closest to the lake, potentially impacting the evening commute in northeastern Illinois and especially northwest Indiana, with snowfall rates of 1-to-2 inches per hour in the most intense areas.
Hazardous Travel Conditions
High temperatures are expected to remain in the teens, contributing to potentially hazardous travel conditions due to slick roads. The NBC 5 Storm Team also warns that blowing snow could further reduce visibility.
Saturday may see lingering lake-effect snow in northwest Indiana during the morning before gradually diminishing. Temperatures are expected to rise into the low-to-mid 20s, a welcome change from recent conditions.
Looking Ahead
Sunday could be even warmer, with highs potentially reaching the upper-20s. However, a clipper system is expected to bring additional snow to the Chicago area, possibly continuing into Monday morning. Forecast models suggest temperatures in the coming work week could return to seasonal averages, with highs potentially reaching the low-30s.
