A blustery storm system moving into the region will bring showers through Western Washington from Thursday afternoon into the upcoming weekend and beyond.

Seattle got a taste of nice and warmer-than-typical weather for Wednesday and much of today, but get ready to break out the scarves and heavier jackets.

Friday will be blustery with highs only getting into the middle 50s.  The normal Seattle high is 59 degrees.

A large pool of cold air to our northwest over Alaska will slide southeast by the weekend.   This is not frigid air, but significantly cooler than what we've been used to this month.

Over the weekend, we'll have occasional lowland showers, and even an occasional rumble of thunder closer to the coast.   Daytime highs will struggle to get much about 50 degrees Saturday and Sunday.

In the mountains, the snow levels will fall to between 2,500 and 3,000 feet by Saturday and stay there throughout the weekend.   

Heavy snow is not expected through our Cascade passes, but there will be a few inches of the white stuff at Snoqualmie Pass, mainly accumulating off the highway.

Slightly more snow will fall at Stevens Pass Saturday and Sunday, but major travel headaches still look unlikely as snow isn't likely to fall in one heavy "burst."   

Still, check with KIROTV.com and the WSDOT for the latest pass conditions before traveling through the mountains.

 

The jackets and scarves are here to stay... at least for a while

Longer-range forecasts indicate this colder and wetter forecast continues through most of next week.   Mountains will continue to get occasional light to moderate snows while the lowlands see often-dreary October rain showers.

We will be able to catch a "break" from time-to-time with areas of sunshine, though as we go through the second half of October, it will certainly feel like Fall!

A far cry from our incredible September and early October!
