Following a soaking November and interior snow this past weekend, residents of the northwestern United States can look forward to an extended period of dry weather.
Seattle; Portland, Oregon and San Francisco and Redding, California all received above-average rainfall last month. Over 8.5 inches of rain was recorded at Seattle-Tacoma International Airport, where about 6.5 inches usually falls in November.
However, a major shift in the weather pattern will become apparent this week to residents and tourists alike as dry weather prevails.
“An extended stretch of dry and tranquil weather is in store for this week,” AccuWeather Meteorologist Kyle Elliott said.
A large area of high pressure, which maintains generally clear and calm weather and blocks incoming storms, will preside over the northwestern United States this coming week.
As a result, warmth and sunshine are expected to build back into the region.

Inland valleys could accumulate pollutants this week with no rain or wind to wash them out.
“As the week progresses, the increasing stagnation of the air mass may lead to poor air quality in the deepest valleys, making outdoor activities dangerous for sensitive groups such as young children, the elderly and those with respiratory conditions such as asthma,” Elliott warned.
This calm regime will also promote potentially dense morning valley fog. Where overnight temperatures dip below freezing, slick conditions could make morning travel dangerous.
"The fog may fail to break in the afternoon in some valleys, which would limit the amount of warming that can take place," AccuWeather Senior Meteorologist Kristina Pydynowski said. "In these type of situations, we typically see mountain areas sunny and warmer than the foggy and colder valleys."
"On the flip side, temperatures would not plummet as much as in the valleys where the sky is clear for a time at night," she said.
Ski bums can enjoy a string of early season blue bird days in the Cascades of Washington and Oregon and the northern Sierras of California, where feet of snow have accumulated on the summits.
“A lack of wind combined with mainly sunny skies will make the air ideal for outdoor activities such as hiking, biking and even skiing,” Elliott said.
This week will be the perfect chance for home and business owners to decorate for the holidays and prepare their property for the winter season.
