Forecasters say an active weather pattern will continue this weekend through Thanksgiving Day.
A series of three pacific frontal systems will bring periods of heavy rain and snow to the mountains. Latest forecast
Rainfall Saturday would likely to exceed an inch, especially from Ocean Shores northward, said KING 5 Meteorologist Jim Guy.
“A Flood Watch has been issued for Mason County. We'll have to keep an eye on the Skokomish River,” said Guy.
Up to 2 inches of precipitation is expected Saturday through Sunday in the mountains, with up to 5 inches of additional precip likely Sunday night through Monday night.
It will be breezy at times through the holiday, with highs around 50 through Wednesday but in the mid- to upper-40s on Thanksgiving Day.
The snow level will fluctuate between 3,000 and 5,000 feet over the next week with a lot of precipitation. The National Weather Service says the higher mountain roads - including Washington Pass on the North Cascades Highway, Mount Baker Highway and the road to Paradise in Mount Rainier National Park - could receive heavy snow Sunday night through Monday night. The Lower Passes – Snoqualmie, Stevens and White - will probably get a mixture of snow, rain and freezing rain.
Travelers should expect mainly rain in the passes Monday and Tuesday, but snow levels will likely fall to about 4,000 feet Tuesday night and Wednesday. That means snow will begin falling in Stevens and White passes. Wednesday night, snow levels will drop to about 2,500 to 3,000 feet and that means snow at Snoqualmie pass.
