Fresh blast of cold and unsettled weather to swing through West

A winterlike storm will plunge into the Pacific Northwest on Sunday, bringing a wet end to the Easter weekend and a blustery and snowy start to the week for much of the West.

Seattle to Portland, and coastal areas in between, can expect rain and drizzle to persist through the holiday, with temperatures remaining seasonable for the end of March.

Northwest Short-Range Regional Weather Forecast

As the weekend draws to a close, the storm will shift inland and usher in unsettled weather to much of the West.

"After a ridge looks to provide some warmth and pleasant weather for many over the holiday weekend, the pattern will change early next week with the approach of a significant upper-level trough," AccuWeather Meteorologist Evan Duffey said.

This means locations that are still in the process of digging out from the last winter storm may have to cope with a fresh round of cold and snow.

"The air aloft will cool off significantly, which will then translate to the surface. Along with the cooler air will come Pacific moisture," Duffey said. "Mountain snows will be possible for some of the higher elevations, while rain showers will cross the rest of the West."

Mountain snow and valley rain, with mixed precipitation in between, will spread from the Cascades into the northern Rockies on Monday, spreading south into the central Rockies by Tuesday.

Southern Montana into Wyoming and Utah into the Colorado Rockies look to bear the brunt of the snow this time around. Snowfall amounts will range from six inches to around a foot at the highest elevations.

Folks returning home from celebrating Easter should double check their travel route and forecast to see if they will encounter heavy snow in the mountain passes of the western states.

Along with the rain and snow, gusty northwesterly winds will usher in colder air to the region. High temperatures will drop by 10-15 degrees from the previous few days across much of the Great Basin and Rockies.

The snow boots and winter jackets will be needed through much of the week before temperatures rebound back to more seasonable levels for the start of April.
