The barometric pressure in Modesto is influenced by the city's location in the Central Valley of California. Pressure changes frequently due to temperature fluctuations. This causes air to expand and contract, resulting in pressure shifts.
Modesto is situated near the Sierra Nevada mountain range to the east and the Coast Ranges to the west. These mountain ranges create a rain shadow effect. As a result, air is forced to rise, cool, and condense, leading to pressure changes. The surrounding landscape also contributes to the formation of high and low-pressure systems.
