Heavy Snow in East Slopes of the Oregon Cascades, Oregon

The Clear Lake SNOTEL measured an estimated 9 inches of new snow in a 24 hour period ending at 1100 PST on 12/20.

An upper level weather system pushed a cold front into the Pacific Northwest late Dec. 18th, where the frontal boundary had stalled across southeast Washington and northeast Oregon through Dec. 20th where the stationary frontal boundary had weakened in the afternoon. As a result, bands of rain, freezing rain, and snow were produced across portions of the forecast area during the 19th and 20th, with snow being reported across the lower elevations in the Columbia Basin and mountain locations across southeast Washington and northeast Oregon.
