Sammamish-Issaquah Weather Forecast: Breezy, Rainy Weekend Ahead

ISSAQUAH, WA — An incoming weather system is heading to western Washington, and is forecasted to bring much stormier weather, at least for the next week.

The National Weather Service updated their forecast Friday, saying they expect the system to bring breezy winds, rain, and even the possibility of snow in some of the foothills and valleys.

The good news: the weekend will not be a total bust. Meteorologists say the weather system won't be arriving until late Saturday night and into early Sunday for most. But when it does, all bets are off and it will be bringing rain and wind to the lowlands, and snow in the mountains.

Some places, like Mount Baker and Snoqualmie Pass, could see up to a foot of snow, and forecasters are advising everyone to avoid the passes if possible, because conditions could become hazardous fairly quickly.

While it likely won't stick around, the National Weather Service also predicts there's a chance for snow in the Cascade Foothills, around Hood Canal, and north of Everett.

As for the breezy weather, that will be at its worst along the coast and San Juan Islands, which could see winds up to 35 mph — strong enough to knock down trees and power lines. Around Puget Sound should be calmer, with winds ranging from 10 to 20 mph.

By Monday the winds should be gone, but forecasters say to expect scattered showers accompanied by high surf along the coast. Then Tuesday, another system will be on the way in, bringing a second round of lowland rain and snow in the upper elevations, which could last through Thursday.

Here is the 5-day forecast for the Seattle region from the National Weather Service:

• Saturday looks to be mostly sunny after some patchy fog in the morning. Afternoon highs should stick in the lower-to-mid 40s. Clouds and a slight chance of rain return in the evening and lows will dip into the 30s. East winds are forecast between 10 to 25 mph, with gusts up to 25 mph.
• Sunday will begin with rain likely in the morning and another chance for precipitation in the afternoon. High and low temperatures are forecast in the 40s, with a south wind Sunday night.
