While measurable snow remains rare in the Valley of the Sun, the white stuff has accumulated on a handful of occasions – most notably in January 1937.
The greatest snowfall on record, 1.0 inch, was reported at the Federal Building (today the United States Post Office), at Central Avenue and West Fillmore Street. Four inches fell in parts of the metro area and lingered for several days in the shade.
Rumor has it in 1898, an unknown author purported the city’s heaviest snowfall (recalled by its oldest resident) would have measured six inches had the flakes not melted quicker than they fell.
