Chicago has begun the workweek with cool and breezy conditions, attributed to a cold front moving across the region. Meteorologist David Yeomans from CBS News indicates that temperatures north of Interstate 80 are unlikely to exceed the 40s°F (4-9°C). The presence of gusty winds intensifies the chill, making it feel colder than the actual temperature. This weather shift is a notable departure from recent warmer conditions, with the cold front bringing a significant temperature drop. Residents can anticipate a refreshing breeze throughout the day but should dress in layers to accommodate the cooler temperatures.
