The Brief Bitter cold continues today with sunshine but highs stuck in the teens. Lake-effect snow is expected to develop near the lake Friday morning, with shifting bands that could disrupt travel. The snow focus moves toward northwest Indiana into the weekend, with colder-than-normal temperatures lasting into next week. This will be the beginning of lake-effect snow, which will move into Chicagoland during the morning and have at least some impact on the commute. By Friday night, the focus is squarely on Northwest Indiana, where a Winter Storm Watch is in effect.
