Winter temperatures in Yellowstone National Park often hover near 0°F during the day (and can dip well below zero!), with highs into the 20s. Sub-zero overnight temperatures are common. The lowest temperature recorded in Yellowstone was -66°F near West Yellowstone in February 1933. Annual snowfall averages near 150 inches in most of the park, and at higher elevations 200–400 inches of snowfall have
been recorded. Occasionally, warm Chinook winds will push daytime temperatures into the 40s, causing significant melting of snowpack, especially at lower elevations.
