Track the barometric pressure in Tucson hour by hour and stay informed about how it will change over the next 6 hours.
The barometric pressure in Tucson varies throughout the year due to the city's location in the Sonoran Desert. Pressure changes are influenced by the seasons and weather fronts. During storms, pressure drops, and during fair weather, it rises.
The pressure is also affected by the surrounding mountains, which block or redirect air masses. Tucson is surrounded by four mountain ranges: the Santa Catalinas, the Tortolitas, the Santa Ritas, and the Rincons.
These mountains create channels for air to flow through, which influences the local pressure. They also create a rain shadow effect, resulting in dry air and clear skies.
