Nearby bodies of water can increase the possibility of rainfall in an area because as water evaporates it enters the atmosphere as water vapor. This brings topography into play. As the moisture in the air reaches higher elevations of topography, it becomes difficult for water to remain in the atmosphere and it precipitates out as rainfall or snowfall. Because of this release of moisture from the atmosphere, areas following mountainous regions tend to see little rain/snowfall.
Hope this helps!
