February 6th

2020: A stalled atmospheric river was followed by a shortwave trough bringing record breaking moderate to heavy precipitation. This led to a mix of heavy rain and wet snow which caused sharp rises in small streams and creeks across parts of the central Idaho Panhandle into the Camas Prairie.

Most school districts cancelled school on February 24th. Eastern Washington snowfall amounts over the three day period in these mountain zones ranged from one to three feet. Several rounds of heavy snow also impacted the upper Columbia Basin and Spokane area mainly on the 23rd and 24th but due to the highly convective nature of the snowfall, storm total snowfall amounts varied from four to fourteen inches.
