Wet & Windy: The Next System Arrives in the West

30 Nov 2017, 9:20 pm

Commonly this time of the year you’ll find us writing about wet weather across the western portion of the United States. To no surprise this article will begin with that story, however it will take a bit of a different turn as we then discuss an extended dry stretch coming in for the first full week of December.

A Winter Weather Advisory is in effect through Friday for parts of Washington.

Rain and snow showers will be confined to mainly Washington on Friday with snow falling above 3,500 feet elevation. By Friday night and Saturday, Oregon will get in on some precipitation of both rain and snow variety. Then more of the Western states will see clouds and rain/snow precipitation as the weekend rolls on. See the timeline images below which show each day and where the fronts, clouds, and precipitation will be.

The forecast for midday Friday, December 1 where blue shows snow, green shows rain, and gray shows the cloud cover.
The forecast for Saturday, December 2 where blue shows snow, green shows rain, and gray shows the cloud cover.
The forecast for Sunday, December 3 where blue shows snow, green shows rain, and gray shows the cloud cover.
The total precipitation forecast through early Monday, December 4.

The weather system will also whip up winds along the Sierra Nevada Saturday with gusts to 50 mph. After this system clears out Sunday night, most of the West will enter a dry period of weather for much of next week as a strong and large area of high pressure builds in.

A wind advisory is in effect on Saturday for gusts up to 50 mph across California and Nevada’s higher terrain.
The precipitation forecast for December 6-10, 2017 where brown shows drier-than-average weather and green shows wetter-than-average weather.

This will give the West an unusual break from the near-constant precipitation that can fall right now. This is the wet season for the Pacific Northwest when November to February features a lot rain and snow.
