The barometric pressure in Evans City varies throughout the day and night. It changes depending on the weather systems that pass through. The pressure rises when high-pressure systems dominate and falls when low-pressure systems approach. This fluctuation affects the weather patterns in the city.
Evans City is situated in a valley surrounded by hills. The nearby hills and mountains influence the flow of air into the valley. As air rises over the hills, it cools, and the pressure changes. This orographic effect contributes to the variability in atmospheric pressure.
The valley's shape and surrounding terrain also impact the weather patterns. The hills create a tunnel effect, trapping and redirecting winds. This can lead to unique weather conditions in the city compared to surrounding areas.
