The barometric pressure in South Pittsburg, Tennessee, is influenced by its location in the southeastern United States. Pressure systems moving from the Gulf of Mexico and the Atlantic Ocean impact the city. These systems bring changes in pressure that affect the weather.
South Pittsburg is situated in a valley surrounded by the Cumberland Plateau to the west and the Appalachian Mountains to the east. The city's valley location creates a unique microclimate. The surrounding mountains force air to rise, cool, and condense, resulting in precipitation.
The city's landscape also generates a rain shadow effect. Moist air from the Gulf of Mexico is blocked by the Cumberland Plateau, resulting in drier air from the northwest. This mix of air masses creates a varied and unpredictable weather pattern in South Pittsburg.
