Barometric pressure

Dulles is located in a valley surrounded by mountains. The Blue Ridge Mountains are to the west and the Piedmont Plateau is to the east. The valley shape creates a unique microclimate.

The mountains influence the atmospheric pressure. They block cold air from the northwest and warm air from the southeast. This leads to a mix of cold and warm air masses.

The nearby Potomac River also affects the atmospheric pressure. It brings moisture from the Atlantic Ocean, which interacts with the cold air from the mountains. This creates a humid and unstable air mass.

These factors combined lead to a dynamic weather pattern in Dulles. The pressure can fluctuate rapidly, causing changing weather conditions.
