Snow will increase Friday across Central Oregon and the higher elevations, lingering through Friday. 1-4 inches of accumulation will be possible across the lower elevations of Central Oregon, with 2-5 inches possible across the east slopes of the Oregon Cascades. Travelers should be prepared for slick roadways and occasional restrictions in visibility in the heavier snow showers.
A low moving into the area will introduce instability along with moisture into the Inland Northwest. The combination of the two will produce rain showers this evening for most of northeast Oregon and eastern Washington. Thursday a cooling trend starts, and the precipitation becomes more persistent with the introduction of mountain snow. This will persist through the weekend, with the heaviest amounts of precipitation are anticipated around south-central Oregon.
