Palmdale is situated in the Antelope Valley. The valley is surrounded by mountains. The San Gabriel Mountains are to the south. The Sierra Nevada Mountains are to the west.
The mountains influence the weather in Palmdale. They block moist air from the ocean. As a result, the air is dry. The mountains also create a rain shadow effect. This means that most precipitation falls on the west side of the mountains, not in Palmdale.
The dry air and rain shadow effect contribute to Palmdale's high barometric pressure. Palmdale's location in the valley also helps to trap the air. This increases the pressure even more.
