How do the Rocky Mountains affect Denver's weather?

The Rocky Mountains significantly influence Denver's weather by acting as a barrier to moisture-laden air masses coming from the west. This results in orographic lifting, which causes precipitation on the western slopes while leaving Denver relatively dry. Additionally, the mountains can create localized weather patterns, leading to rapid temperature changes and sudden storms in the Denver area. Overall, the Rockies contribute to Denver's semi-arid climate and variability in weather conditions.
