what's the average snowfall in flagstaff arizona
Flagstaff, Arizona The annual snowfall averages 100.3 inches (254.76 cm), placing Flagstaff among the snowiest incorporated cities in the United States.[28] Overall, the city features an average of 277 days without measurable precipitation each year. Despite snowstorms often being spread weeks apart, snow often covers the ground for weeks after major winter storms due to the low night temperatures refreezing the snowpack, even when daytime temperatures are above freezing. The maximum daily snow cover has been 83 inches (210.82 cm) on December 20, 1967, although the mean maximum for a full winter is only 20 inches (50.80 cm) and the lowest maximum only 6 inches (15.24 cm) in the dry winter of 1955–56. However, due to the infrequent and scattered nature of the snowstorms, persistent snow pack into spring is rare.[10] One notable exception occurred during the severe winter of 1915–16, when successive Pacific storms buried the city under over 70 inches (177.80 cm) of snow, and some residents were snowbound in their homes for several days.[29]
