Today's Forecast

Updated Thursday 3:40 p.m.

After taking a few days off, Mother Nature has started poking around the Pacific Northwest again, tossing a few weather systems of note our way that have us chatting wind advisories and mountain snow advisories and potential flooding advisories, on top of the usual "be careful that package on your doorstep might be a fruitcake" advisories this time of year.

Our first weather system is up this evening, bringing steady rains overnight and some gusty southeast winds to the Northwest Interior. A Wind Advisory is in effect until midnight for western Whatcom County, the San Juan Islands, and the Whidbey/Camano Island and Admiralty Inlet areas for gusts up to 45 mph. The rest of the region will be a little breezy at times but nothing concerning.

The system will finally bring some snow to the mountains as well - a Winter Weather Advisory is in effect for the Cascades for about 6-10" above 5,000 feet although a few inches could fall this evening in Snoqualmie and Stevens Pass before it warms up a little there. But for most everyone in the lowlands, rain at times with lows around 40.

Friday will see rain early tapering to showers with highs around 50.

Our next storm is speeding up a touch to where rain will arrive around dawn Saturday and just chalk up the weekend to wet and windy as the storm will stick around for a while. Highs both days will be in the low-mid 50s, so...so much for a lot of that mountain snow that just fell. Instead, we're keeping an eye on river flooding potential by the end of the weekend -- certainly on the Skokomish.

Rain tapers to just a few showers Monday, and then a little light rain returns for Tuesday and Wednesday before we dry out just in time for Christmas. Highs will slowly cool from near 50 on Monday to the mid 40s by Wednesday.

Long range models are now hinting at a colder pattern starting Christmas Day and lingering into the weekend. It's not looking super cold but when it seemingly has been 55 every day in December, low 40s for highs might seem colder than usual :) We'll keep an eye on it but nothing too concerning (or exciting) for now. Looks like occasional breezes and sneaky fruitcakes remain the items to watch out for this week :)
