Barometric pressure in Mount Vernon is influenced by the city's proximity to the Pacific Ocean and the surrounding mountains. It tends to be relatively low due to the oceanic influence. This leads to a fluctuation in pressure, resulting in changing weather conditions.
Mount Vernon is situated in the Skagit Valley, surrounded by the Cascade Range to the east and the Olympic Mountains to the west. The valley's unique layout creates a rain shadow effect, blocking moisture-laden air from the Pacific. This results in a drier climate than expected, given the city's coastal proximity. The nearby mountains also disrupt airflow, creating an orographic effect that amplifies precipitation.
