A wintry mix of precipitation is expected across the Pacific Northwest and Northern Rockies through Sunday afternoon as a series of systems move across the region. Snow will transition to freezing rain across portions of Oregon on Friday. Snowfall accumulations of 3-6 inches are expected for the valleys of Oregon and 6-12 inches in the higher elevations. The highest elevations may see over a foot of snow. In addition, freezing rain of up to 0.2 inch is expected. Further east from eastern Oregon to western portions of Montana and Wyoming, 6-10 inches of snow are possible with as much as 15 inches in the higher elevations.

Dense sea fog is forecast to form off the Texas coast after midnight due to light to gentle winds and plentiful moisture across the region. Visibilities less than two miles are possible through Friday morning before winds increase out of the north-northeast.
Excessive Rainfall Possible for Northern California on Friday
As the upper level low that brought snow to the Sierra Nevadas on Thursday continues to track into the Pacific Northwest, ample moisture will spread across California and southern portions of the Pacific Northwest. Showers will become steadier and intensify through the day. Rainfall accumulations of 1-3 inches are forecast. Given recent heavy rainfall, localized flooding and runoff will be a concern.
Major Cities in Region: Eureka, CA, San Francisco, CA, Sacramento, CA, Fresno, CA
