Rain Shadow and Lake Effect
Both of these weather patterns have significant impacts on overall climate and daily weather conditions in the Reno area. The rain shadow effect is responsible for Reno's desert climate, while at the same time we can actually see significantly more precipitation coming down just west of town in the Sierra Nevada.
The huge body of water known as Lake Tahoe affects local weather with a phenomenon known as lake effect. When conditions line up just right, storms passing over Lake Tahoe pick up extra moisture and bring it over to our side of the mountains. This can result in occasional storms with heavy rainfall and/or snowfall in the Reno area.
