The barometric pressure in Tonopah varies throughout the day. It changes depending on weather systems that move into the region. Low pressure systems bring storms and cloudy skies. High pressure systems bring clear skies and fair weather.
Tonopah is situated in a high desert valley. The surrounding mountains create a rain shadow effect. Moist air from the west is blocked by the Sierra Nevada mountain range. This results in a dry climate with little precipitation.
The valley's elevation also affects the atmospheric pressure. Cold air from the north settles in the valley. This creates a high pressure system that dominates the region. The resulting clear skies and fair weather make Tonopah a popular spot for stargazing.
