The barometric pressure in Roanoke varies throughout the year. It can rise and fall significantly within a short period. This affects the weather conditions.
Roanoke is situated in the Blue Ridge Mountains of southwest Virginia. The surrounding mountains influence the atmospheric pressure. They block and redirect air masses.
The mountains create a rain shadow effect. Moist air from the east is forced to rise, cool, and condense. This results in precipitation on the eastern side.
The valley where Roanoke is located remains relatively dry. The air is drier and warmer than in the surrounding mountains. This difference in air masses creates unique weather patterns.
