The barometric pressure in Collegedale, Tennessee is measured in inches of mercury. It rises and falls with changes in the weather. When a low-pressure system approaches, the pressure drops. As the system departs, the pressure increases.

Collegedale is situated in a valley surrounded by the Appalachian Mountains. The mountains block air masses from the east. This blockage causes air to rise, cool, and condense, resulting in precipitation. The valley's shape also contributes to temperature variations.

The surrounding mountains influence the atmospheric pressure in Collegedale. They force air to rise, creating an area of low pressure near the city. The pressure difference drives winds into the valley. These winds bring weather systems from the west and southwest.
