Salem's barometric pressure varies throughout the year, influenced by its location in the Midwestern United States. The pressure changes with the seasons, responding to temperature and humidity shifts. This fluctuation affects the local weather, leading to distinct seasonal patterns.

The city of Salem is situated in a region of rolling hills and vast plains, which impacts the atmospheric pressure. The nearby Mississippi River Valley creates a pathway for air masses to move into the area. These air masses bring different weather conditions, influencing the local pressure. The surrounding hills and plains also disrupt airflow, causing pressure changes.

The terrain around Salem creates a unique microclimate, leading to variations in pressure within the city. As air masses move over the hills, they are forced to rise, causing pressure to drop. This, in turn, affects the local weather, resulting in unpredictable changes.
