Barometric pressure in Park Forest, Illinois changes throughout the year. It is influenced by the city's location in the Midwest. Pressure systems from Canada and the Gulf of Mexico move into the region, causing shifts in pressure.
Park Forest is situated about 30 miles south of Lake Michigan. The lake's presence helps moderate the city's climate. The surrounding landscape is mostly flat, with some slight elevation changes. This terrain allows air masses to move freely into the region. The city's proximity to the lake also leads to increased moisture in the air.
The combination of the lake's influence and the flat landscape contributes to changes in atmospheric pressure. This, in turn, affects the weather patterns in Park Forest. The city experiences a mix of cold arctic air from Canada and warm, moist air from the Gulf of Mexico. This clash of air masses leads to varying weather conditions throughout the year.
