Good evening, Chicago! Yesterday, we experienced a pleasant range of 8 to 23 degrees, with air quality consistently rated as "Good." However, today’s chill has settled in, with highs only reaching a brisk 7 degrees under cloudy skies, but don’t worry, the air remains just as satisfactory! Looking ahead to tomorrow, we might see the first sign of winter returning with temperatures dipping to just 1 degree and the possibility of snow flurries. So bundle up, as this is one forecast that could really *snowball* into a chilly surprise! Keep those jackets handy, or you might end up in a frosty *forecast*!
