50 shades of gray to start the work week.
On December 8th, 1971, Tucson saw its largest snowfall on record. A whopping 6.8″ fell after midnight at Tucson International Airport. Major issues ensued. Here’s a brief recap from NWS Tucson:
The heavy snow snarled traffic, closed the airport, downed power lines and damaged or destroyed 3000 trees, some of them 20 years old. Slush on the runway forced the closure of the Tucson International Airport and cancellation of flights between 6 AM and 11 AM. At the time, the airport did not own a snow plow.
What caused this rare desert snowstorm? The morning of December 8th, 1971 showed a very cold mid-level low pressure center in northwestern Arizona. This remarkable air mass can easily support low elevation snow.
Only question is whether the ongoing precipitation can sync up with the cold air for a long period of time. In my time in Tucson, a winter pattern like this usually sees a brief switch-over to snow. This event was one of the few that became a prolonged all-snow event.
Above are some photos from viewer Troy Van Zandt at the intersection of Beverly & San Francisco. If you lived in Tucson & have pictures from that day, drop me a line at firstname.lastname@example.org. I’d love to show off your snow pics!
Autumn 2018 actually felt the part for the Sonoran Desert.
The 70s strike back, but only for a limited time.
Sunshine to start the week, but an unsettled finish awaits.
Over the river and through the woods to grandmother’s house today?
