Wider weather episode

An arctic front briefly dropped down into eastern Washington and north Idaho on January 13th and 14th. Light snow accompanied this frontal passage with generally 1 to 3 inches of snow accumulation around the region. However the front stalled along the Washington/Oregon border and promoted an extended period of light snow which left a swath of heavier accumulations over the Lewiston area.
