Rain, snow and cold air will return to the Northwestern states into Thanksgiving.
A storm system will dive southward along the West Coast into Tuesday before tracking eastward across the Rockies into Thanksgiving Day.
The strength and track of this storm system will determine which locations will receive the heaviest snowfall on the cold side of this system.
The amount of moisture available with this system will be much less than the previous storms this month across the Pacific Northwest. While much of the lower elevations will deal with periods of rain, the threat for flash flooding will be low.
“Snowflakes will mainly just make an appearance in Seattle and Portland, Oregon, on Monday night,” AccuWeather Senior Meteorologist Kristina Pydynowski said. “The low elevations east of the Cascades have the better opportunity to receive accumulating snow on Tuesday into Wednesday, especially in eastern Oregon.”
