Forest Park's weather is affected by its location near Lake Michigan, which helps regulate air pressure. In winter, cold air from Canada presses down, making air pressure high. In summer, warm air from the Gulf of Mexico rises, making air pressure low.
The park's flat geography doesn't block air masses, so air pressure changes smoothly. This means weather patterns can move quickly, bringing sudden changes in temperature and humidity.
In spring and fall, air pressure changes rapidly, causing unstable weather with rain and wind. In winter, high pressure brings cold and clear skies, while summer's low pressure brings warm and humid air.
Forest Park has a humid continental climate, with large temperature differences between winter and summer. This means air pressure changes greatly between seasons, leading to varied weather patterns throughout the year.
