Chicago Weather: Your Ultimate Guide To Understanding The Windy City's Climate - The Heatwave of 1995 was a devastating event that claimed the lives of over 700 people in Chicago. Temperatures soared above 100°F (38°C) for several days, and high humidity levels made the heat feel even more oppressive. This event underscored the importance of preparing for extreme heat and ensuring vulnerable populations have access to cooling centers and other resources. One of the most famous extreme weather events in Chicago's history is the Great Chicago Fire of 1871.

However, it also contributes to the "lake effect," a phenomenon that can lead to heavy snowfall and sudden temperature changes.
For example, the frequency and intensity of extreme weather events have increased in recent years. Heatwaves are becoming more common, and the city is experiencing more intense rainfall events. These trends are consistent with global climate patterns and highlight the importance of understanding how climate change may affect Chicago weather in the future.
