The barometric pressure in Shawnee, Oklahoma, fluctuates constantly. It changes with the weather patterns that pass through the city. Pressure rises when high-pressure systems dominate the weather. It falls when low-pressure systems move in.
Shawnee is situated in a relatively flat area of central Oklahoma. The surrounding landscape is characterized by rolling hills and vast prairies. This type of terrain allows air masses to move freely. They can sweep across the region unobstructed, influencing the local pressure.
The nearby Arbuckle Mountains, about 30 miles to the south, have a slight impact on the air flow. They can deflect or redirect air masses, causing pressure changes in Shawnee. However, their effect is limited due to their relatively low elevation.
