A stormy pattern returning to the northwestern United States will bring rounds of rain and slower travel to the region into next week.
The large area of high pressure that kept the region rain-free and warm this past week has weakened which has opened the door for storms with clouds and rain to roll ashore.
While the weekend will not be a washout by any means, area residents will dodge on-and-off showers and locally heavier downpours into Monday.
Saturday may feature the most dry breaks of the weekend along the Pacific Northwest coast.
The greatest threat of rain will arrive Saturday night into Sunday morning along the Washington and Oregon coasts as a storm moves onshore.
"This storm will move farther inland on Sunday, spreading rain showers into the valleys of Washington and Oregon, and even some mountain snow across the Cascades," AccuWeather Meteorologist Brandon Zapolski said.
Several inches of snow could fall across the Cascades before winding down on Sunday night.
Snowfall will have a difficult time sticking to the roadways during the day due to the recent warmth and strong sun. Still, motorists should remain vigilant for slick spots especially during the overnight and early morning hours.
The threat for flash flooding will remain low in the milder valleys, but pooling of water is possible in poor-drainage areas.
Low cloud ceilings could force minor delays at the airport.
"There could be some minor travel delays on the roads and in the air as a result of the rain and mountain snow, but the bigger concern will be disruptions to outdoor activities," AccuWeather Meteorologist Matt Rinde said.
Anyone heading to the Tacoma Rainiers minor league baseball games in Tacoma, Washington, should bring along rain gear as wet weather could force delays on Saturday night and Sunday.
Increased clouds and rain will put an end to the record warmth that prevailed across the region. After nearly hitting 90 degrees Fahrenheit last week, both Portland, Oregon, and Seattle will struggle to reach highs in the low 60s, which is more typical for this time of year.
Drier air is expected to move into coastal regions on Tuesday before more wet weather arrives at midweek.
The cycle of storms moving ashore every few days is expected to continue through the middle of next week, Zapolski explained.
