Today's Forecast

Updated Monday 4:15 p.m.

Turkey, yams and pumpkin pie are just part of the Thanksgiving tradition around the Pacific Northwest -- usually stormy weather is a part of it too, thanks to the holiday coming right smack dab in the heart of the rainy season. Looks like this year will be no different.

A series of four storms are set to roll through the Northwest this Thanksgiving week, and the accumulative rainfall may be enough to send some rivers over their banks, especially since snow levels are expected to remain relatively high for the season.

A Flood Watch has been issued for all rivers in King, Pierce, Snohomish, Skagit, Whatcom and Lewis Counties from late Monday night through late Wednesday night -- this is for the first two storms coming in back-to-back. Rain will develop Monday evening and fall with moderate to heavy intensity in the mountains through much of Tuesday-- and into Wednesday.

For the lowlands, models show roughly an inch of rain in the lowlands (much less in the Olympic Rain Shadow areas) but as much as 2-5 inches in the mountains with some isolated spots going well over 5 inches. River forecasters are warning these rivers have the greatest potential for flooding: the Snoqualmie, Tolt, Stillaguamish, middle fork of Puyallup, and Nooksack. Others bearing watch are the Skagit, Snohomish, White and Cowlitz.

For the rest of us, just a rainy period. Rain will continue to fall overnight and through much of Tuesday with lows tonight in the low-mid 40s warming to the low-mid 50s Tuesday.

Rain holds into Tuesday night and Wednesday although perhaps a little lighter rain Wednesday. Highs will stay in the low-mid 50s.

More systems keep chugging through Thanksgiving Day and Friday for more rain at times and blustery winds with highs still in the low-mid 50s.

If you're looking for a place to escape the deluge, head to the Olympic Rain Shadow areas, which models suggest will be in full force for much of the week. Those in Port Townsend and Sequim will wonder why we're talking flooding potential and a soaked Seattle.

Snow levels are well above pass level through Friday so no snow issues for pass travel at least heading out (perhaps coming back Saturday/Sunday, but won't be nearly as much moisture)

More rain in the lowlands Friday but then we begin to wring out to where it's just a few lingering showers Saturday (highs still in the 50s), and then perhaps a dry Sunday and Monday. Temperatures will cool with the clearing skies with highs down into the 40s again with lows in the 30s.

And if you want the super long range forecast inkling, it looks chilly in Pullman for the Apple Cup Saturday and maybe some flurries.
