Climate - The climate in Wyoming changes with the topography. Generally the western mountains and basins receive large amounts of precipitation and create a rain shadow for eastern Wyoming. Most of the precipitation occurs during the winter months and falls in the form of snow. Temperatures are cooler in this region than the eastern part of the state, because of the generally higher elevation.
The eastern and lower elevations of Wyoming have been known for the constant wind that blows from west to east. During the winter this may be a Chinook, which warms the region. Temperatures in eastern Wyoming can be extreme. Summer days may reach 100 degrees F cooling quickly after sunset. Winter temperature lows can reach below zero with the wind adding to the intensity.
