Storms will bring more rain and mountain snow across the northwestern United States through the weekend.
Storms have brought rain to much of the Pacific Northwest every day since Feb. 10, dropping 1 to 3 inches of rain from Seattle to Portland, Oregon. More than 9 inches of rain has fallen in Quillayute, Washington.
Following a round of rain on Thursday, another storm will bring rain during Friday into Saturday morning. This storm will not bring enough rainfall to raise the risk of flash flooding.

Those heading to and from work will have to deal with wet roads through Friday. Those traveling on the highways should lower their speeds to reduce the risk of hydroplaning.
This storm will continue to usher in cooler air that will cause snow levels to drop to pass levels.
"The storm Friday into Friday night will bring a fresh 6-12 inches of snow to the Cascade Mountains," said AccuWeather Senior Meteorologist Kristina Pydynowski. "Travel conditions will deteriorate on I-90's Snoqualmie Pass later Friday into Friday evening as snow levels drop."
"Following the rain and mountain snow on Friday and Friday night, the Northwest will turn quiet with a dry period through Sunday morning," AccuWeather Meteorologist Ryan Adamson said.

Saturday will turn out dry for most in the Pacific Northwest as spotty showers diminish.
"A new storm will approach the Pacific Northwest on Sunday with more rain and mountain snow," Adamson said.
Rain will be the steadiest during the afternoon and taper off into Monday morning.

A ridge of high pressure is forecast to build across the West Coast for next week, causing any storms to remain in the Pacific Ocean or track northeastward into western Canada.
There could be a couple of weak systems bringing spotty showers during the week, but no areas of moderate or heavy rain are expected.
Dry weather could stretch to the end of the week. If it does, it would be the longest stretch of days between storms for Seattle and Portland since between Feb. 6 and Feb. 9.
