Beginning during the early morning hours of December 31st and lasting into the morning of January 1st, 2020 a moist northwesterly flow off the Pacific enhanced over a warm front into widespread snow over the Northeast Mountains and the northeastern Columbia Basin of far eastern Washington including the Spokane area. Heavy snow accumulations were noted in these areas during the morning hours before temperatures increased to above freezing and began melting the accumulation. While lighter amounts were noted across the Okanogan Highlands, the orientation of the flow promoted a precipitation shadow over the Cascades and areas in the western and central Columbia Basin.
