The amount of snow a desert receives would depend upon where the desert is located. Some deserts never, or rarely, receive snow. Others my receive a few inches of snow each year that, usually, is quickly melted or evaporated. The qualifying factor is that the region receives less than 10 inches (250 mm) of precipitation (rain and melted snow) per year on average. Since 10 inches of snow equates to about 1 inch of rain, a desert could, theoretically receive about 100 inches (250 cm) of snow and still be considered a desert.
Some deserts see very little snow ever. Others, such as the Sonoran and Chihuahuan Deserts may receive an inch or more during the winter but it usually disappears in hours. Cold winter deserts, such as the Great Basin and Colorado Plateau, have parts that may receive several feet of snow during a particularly bad winter.
