Chicago, Illinois, US

Good morning, Chicago! Yesterday felt like a freezer with temps plummeting to a brisk -15°C in the morning, but air quality remained good. Today, we're waking up to slightly less frigid conditions, with highs reaching a mild -1°C this afternoon. However, the air won’t be entirely spring-like, as air quality is moderate throughout the day. And for tomorrow, expect to see a slight warm-up with highs nudging just above zero at 1°C! So bundle up, and let’s hope the winds of change start blowing in a bit more warmth as we wade through this chilly winter!
