A weakening frontal system will move across western Oregon and southwest Washington Tuesday afternoon and evening. This front will spread a widespread area of precipitation across most of the area for a few hours beginning early afternoon Tuesday along the
coast, and spreading to areas farther east into the Cascades by Tuesday evening.
Locations at elevations of 500-700 feet and higher could see a slushy inch or two of accumulation. In general, snow accumulation on roadways is expected to be minimal to none, but bridges, overpasses, ramps, and other elevated or exposed road surfaces are the locations most likely to see accumulation, and possibly some local slick spots. Any snow in low elevations below 500 feet should taper off to flurries or change back to very light rain by late evening Tuesday.
Locations in the Coast Range and Cascades Foothills above 500 feet could see 2 to 5 inches of accumulation including the cities of Astoria, Cannon Beach, Tillamook, Netarts, Pacific City, Lincoln City, Newport, Cape Foulweather, Yachats, Florence. Higher elevations above
1200-1500 feet in the Coast Range and Cascades will likely see even higher snow accumulations from 5 to 8 inches. Anyone with travel plans Tuesday afternoon and evening should be prepared for the possibility of winter driving conditions at low elevations, with winter driving conditions a virtual certainty in the mountains above 500-1000 feet elevation.
