Hereford is surrounded by mountains to the east and west. The San Rafael Valley lies to the south. The surrounding landscape affects the atmospheric pressure. The mountains block moisture from the Gulf of California. This keeps the air dry and contributes to the high pressure.
The valley allows cool air from the north to enter the area. This cool air sinks, causing the pressure to rise. The unique combination of mountains and valley shapes the local climate.
