In the Northwest, another “atmospheric river” storm is poised to make landfall in western Washington state with rain on Thursday, National Weather Service speak.
“West of Washington is likely to see a prolonged spell of rain with abundant moisture in the Pacific, leading to moderate to heavy rainfall over Thanksgiving,” the weather service said.

“Seattle has recorded a whopping 8.40 inches of rain so far in November, 174% of normal through November 23,” said AccuWeather meteorologist Alyssa Smithmyer.
Unlike the Pacific Northwest, the vast majority of the West will enjoy dry weather “through the end of Thanksgiving and into Black Friday thanks to an enhanced dome of upper high pressure extending from California to Great Plains.” Weather service said.

Weather.com Meteorologist Orelon Sidney said that interspersed snow and rain were also likely across parts of New England on Friday.
The new cold front is likely to bring the lowest temperatures of the season so far across much of the Midwest and Northeast on Friday, AccuWeather said.
For his trip home over the weekend, on Saturday, more rain will hit Texas, while Seattle will still be subject to rain delays, Sidney said. On Sunday, she said trouble spots would include the Great Lakes and the Ohio Valley, where light snow is possible.
