Good evening, Chicago! Yesterday was a bit of a rollercoaster with temps ranging from the 37s to nearly 49°F, all under partly cloudy skies and acceptable air quality. Fast forward to today, and we've bumped our afternoon highs up to 58°F with clear skies and the air quality remaining in the satisfactory zone. Tomorrow, however, it looks like we'll be cooling down again with overnight lows dipping to the mid-20s. Better grab your heavy coats as the chill sets in! With all that fresh air around, don't forget to enjoy the winter scenery!
