a cold front moved through the region on November 2nd. This

strongest winds occurred across south central Washington. A wind
sensor 8 miles northwest of West Richland reported a wind gust up to
68 mph during the afternoon on the 2nd. A wind sensor at Vista Field
in Kennewick reported a wind gust to 63 mph. A weather spotter four

large tree fell due to the wind, knocking out the power.
A moist weather system moved into the region November 15th and
16th. While many lower elevations reported snow, snow levels lowered
to around 4000 feet, leading to snow in the higher elevations of the
Blue Mountains. The Touchet snotel site reported a total of 11
inches of snow in 24 hours. And a cocorahs observer 4 miles
northwest of Meacham reported a snow total of 8 inches in 15 hours.
