Heavy Snow in Northeast Blue Mountains, Washington

A potent and moist Pacific storm system slammed into the Inland Northwest from the afternoon hours of February 22nd through midday on the 23rd. A combination of moist isentropic ascent coupled with strong orographic flow resulted in heavy mountain snow across the mountains of Eastern Washington. Snow levels started off near valley floors but eventually rose near 3000 feet as warmer air punched into the region. Valley locations across Northeastern Washington received between one to three inches of snow while eight to twelve inches fell in the mountains.
