Snow buries northern Arizona; flurries delight in desert

A series of storms dropped more precipitation in Flagstaff than the city had during last summer's monsoon season. 

The mountainous northern Arizona city recorded its driest monsoon seasons on record in 2020 and 2019. 

The snowfall measured as water easily topped the 1.78 inches that fell as rain from mid-June to September. 

More snow is expected overnight into Tuesday before the storm moves out, even in lower-lying areas. 

A blast of cold will follow in its footsteps.

Snow levels will crash down to around 2,000 feet! 

By the end of the event Tuesday evening, many higher elevation neighborhoods will have a snow depth of 1-3 feet with several inches of snow at the lower levels.

As the showers taper off and the winter storm makes its exit, it’ll leave a calling card of extra cold temps. 

Wednesday morning wakeup temperatures could fall to freezing for several Valley neighborhoods with some below zero readings up north!

Another low pressure system will have its sights set on Arizona at the end of the workweek and into the weekend. 

This will send in another round of rain and snow for the state.
