White Christmas
Will Lewiston, ID have a white Christmas?
Lewiston, Idaho had snow on the ground on Christmas morning in 3 of the 21 Christmases measured from 1996 to 2025. The last white Christmas there was in 2017.
Measured at Lewiston Airport, 3 miles south of Lewiston. That station is far enough from Lewiston, or high or low enough, that this is its own record rather than a call for the town. A white Christmas is an inch or more of snow on the ground at the Christmas morning reading, the line NOAA uses, counted from the station's own daily record.
The forecast for Christmas morning in Lewiston starts on this page on December 18.
