Chicago's First Snowflakes Expected This Week
Chicago and northwest Indiana are bracing for their first snowflakes of the season as colder weather moves into the region. According to the National Weather Service (NWS), lake-effect rain showers will begin Thursday, spreading inland across northeastern Illinois and northwestern Indiana. By Thursday night, rain may mix with snow, particularly in northwest Indiana, with slushy accumulations possible on grassy and elevated surfaces. The lake-effect band is expected to shift eastward into Indiana by Friday, with snow mixing with rain at times. Conditions will improve by Saturday, with drier weather returning Sunday. This marks the start of the winter season for the area, as Chicago's average first trace of snow typically occurs on October 31. Source time: not specified.
