Rock Springs is in a high-pressure zone due to its location in a valley, surrounded by mountains, which traps warm air and creates high pressure.
The city's geography, with the Sierra Madre Range to the south and the Uinta Range to the north, blocks moisture from the Pacific Ocean, leading to dry air and high pressure.
In the winter, cold air from the Arctic brings low pressure, causing cold and snowy weather. In the summer, warm air from the Gulf of Mexico brings high pressure, leading to hot and dry weather.
Rock Springs has a semi-arid climate, meaning it's dry with low humidity, which contributes to its high-pressure weather patterns and clear skies most of the year.
