Most snow fell in less than 12 hours overnight into the early morning hours of February 15th. Snow covered roads and blowing snow made travel dangerous, especially for the morning commute. Light snow continued through the day and on the 16th. The Lewiston-Nez Perce County Airport set a new record February 15 snowfall with 3.7 inches, which was previously 0.6 inches in 2019.

Wider weather episode

A winter storm brought widespread snow to the Idaho Panhandle on February 14th and 15th. Light snow continued to linger in the Idaho Panhandle into the 16th. Moderate to heavy snow accumulations, from 4 to 10 inches, fell in the southern half of the Panhandle. This created difficult driving conditions, especially during the morning and evening commutes. Blowing snow, in the Idaho Palouse, limited visibility on roadways, such as Highway 95.
