Truckee's mountainous location makes its air pressure lower compared to cities at lower elevations. This means air rises, cools, and condenses, resulting in more precipitation.
Truckee's surrounding Sierra Nevada mountains block some air masses, directing others to rise and cool, causing more snow and rain.
In winter, cold air from the north dominates, bringing low air pressure and heavy snowfall. In summer, warm air from the southwest brings high air pressure and dry weather.
