Weather updated Friday January 21 -David Lovejoy
The weather last week was cool and calm, with light snowfall on Tuesday and the delayed passing of our lingering cut off low. Still, Snowbowl recorded 3“ of new snow at 10,800’ on Wednesday morning January 19.
Since then, a steep wave of high pressure over southern California is steering a short wave low towards our region, dropping southward from the Great Basin. Although the storm is cool and on the dry side, due to its northerly overland path, it will intensify as it transforms into a closed low pressure cell before impacting Arizona. On Friday afternoon through Saturday, San Francisco Peaks could get 3-6 inches of snow at 10,800’ along with strong southwest, shifting to to northeast winds in the range of 20-35 mph. Snow line will be 5000-5500 feet.
Drying and gradually warming weather will follow, characterizing the up coming workweek with a return to seasonally normal temperatures. Regretfully, no precipitation producing storms are evident on the horizon. A dry short wave low will cool temperatures and produce breezy weather on Tuesday and Wednesday, but after this, the California high appears to be spreading its influence over the entire Southwest.
Snowslide SNOTEL reports 30” (76 cm) of snow at 9,730' on Friday, January 21. So far this winter, we have had a total of 81" (206 cm) of snowfall at 10,800' with a 46" (117 cm) undisturbed settled base depth reported by Arizona Snowbowl on January 21.
