Bundle up and brace for what could be the coldest weather western Washington has seen in a long while, says KNKX weather expert Cliff Mass.

A blast of Arctic air is headed our way, creating what will be a major cold wave over the next several days. Mass says it’s going to get really wintry around here.

Bundle up and get ready for possible lowland snow in places. KNKX weather expert Cliff Mass says cool air moving in to western Washington will push temperatures below freezing in many lowland areas this weekend, with a chance of snow most likely on Sunday.

Unusually heavy rain and flooding are in the weekend forecast, with the worst hitting Sunday as an atypical atmospheric river sets up from due west and aims its warm plume at western Washington.

KNKX weather expert Cliff Mass says that phenomenon means the rain total by the end of this weekend could be 5-10 inches over the lower slopes of the central Cascade Mountains.

Batten down the hatches and keep your rain gear handy. A Pacific cyclone is headed toward Vancouver Island, British Columbia. While the highest winds will likely hit north of the Canadian border, KNKX weather expert Cliff Mass says people in western Washington will notice it too, especially toward the coast.

This week, an extraordinary offshore storm produced waves in the Northwest that were 30 feet tall and higher in some places places. One even swept a man out to sea near Lincoln City, Oregon, on Thursday.

But KNKX weather expert Cliff Mass says that event is over, and we can expect more run-of-the-mill winter weather in the days to come.

It’s been a wet and blustery week in Western Washington. That’s typical weather for this time of year in the Pacific Northwest, but KNKX weather expert Cliff Mass says this weekend will be fairly dry. With lots of fresh snow in the mountains, conditions are good for winter sports enthusiasts, especially on Sunday.

Rain and cloudy skies have returned to much of the Puget Sound region. KNKX weather expert Cliff Mass says Western Washington can expect more of this showery, gray weather over the next few days. But that’s in contrast to what has actually been a much sunnier winter than usual in the northwest.

If you’ve ever hiked to the top of a mountain and found yourself shedding layers of clothing because of increasing warmth, you’ve experienced a temperature inversion. They’re strongest in winter and can come with some unpleasant side effects, such as the freezing fog and declining air quality the greater Puget Sound region recently experienced in mid-December. Temperatures in the lowlands were near freezing at the time, but hit 55 degrees at Hurricane Ridge in the Olympics.

Are you dreaming of a white Christmas? Keep dreaming, if you’re in western Washington. A couple of feet of snow fell on local ski areas earlier this week, but that’s pretty much over for now. And there’s little prospect of much holiday snow accumulation in the lowlands.

The mountains can be so alluring this time of year, with views of snow-covered peaks all around us. Yet it can be hard to find good conditions for cold-weather fun such as skiing or snowboarding.

Precipitation and warmer temperatures have returned to the northwest. Light rain was falling all around the region Friday morning as fresher air moved in after a week in which a substantial ridge of high pressure had dominated and trapped in smoke all the way from the California wildfires.  Also gone were the freezing fog and black ice.  

KNKX weather expert Cliff Mass says this mild pattern will continue this weekend and into mid-week.

A strong ridge of high pressure has brought a string of sunny days to the Puget Sound, as well as patches of morning fog that is often accompanied by black ice. KNKX weather expert Cliff Mass says he expects that pattern to stick around for quite a while.

Hang in there if the dreary weather in western Washington has been getting you down. It will be wet and cool again this weekend. But then a system of high pressure sets up and KNKX weather expert Cliff Mass expects a major shift in the weather for a least a week.

Have the wet weather and dark days got you down? You’re not alone. Seasonal Affective Disorder, or SAD, is extremely common in the Pacific Northwest. Recent rains and abundant cloudy skies seem to have exacerbated some people’s experience of the lack of light this time of year, says KNKX weather expert Cliff Mass.

We will be seeing a lot of rain into Thursday with the expectation of flooding in certain parts of Western Washington. And the tropical air that has moved into the region brought a record breaking high temperature for Tuesday night as well.

Another weekend dominated by mostly showery weather lies ahead, with the driest conditions on Saturday.

KNKX weather expert Cliff Mass says that would be a great day to head for the passes and enjoy some wintery fun. Stormy weather earlier this week dumped several feet of snow in the Cascades, allowing all the big ski areas to open.

Keep your rain gear handy. A mostly sunny start to the weekend on Friday provided a brief respite from the cold, wet and dark skies that are typical for mid-November in the Northwest, but KNKX weather expert Cliff Mass says don’t be fooled.

Wet snow was on the ground Friday morning in many places around Puget Sound, as cold air surged in from British Columbia.

“Particularly if you were away from the water or at 500 feet or above,” said KNKX weather expert Cliff Mass.

“Perfect fall weather,” is in store through the end of the month in the greater Puget Sound region, says KNKX weather expert Cliff Mass.

Halloween should offer ideal conditions for trick or treaters. Expect dry skies and warmer than normal temperatures, with some low clouds and morning fog this weekend. After that, a dramatic shift is in store, so enjoy it while you can.

Stormy weather that took out power for tens of thousands of residents in the Pacific Northwest this week made national headlines as The Washington Post commented on the fascinating “river in the sky” that has been dumping rain on the region.

If the cool and cloudy weather that’s been dominating in the Puget Sound region this week has got you down, hang in there. KNKX weather expert Cliff Mass says the weekend forecast is “improving” and there will be a fair amount of sun poking through, especially on Sunday.

An abundance of crisp blue skies have ushered in a relatively dry start to fall this year in the Pacific Northwest, providing a stunning backdrop as the leaves begin to turn. Some sunnier afternoons allowed folks to keep wearing their shorts and sandals. But KNKX weather expert Cliff Mass says there are some sure signs of autumn.

Seattle saw the mercury hit 86 degrees on Thursday, breaking another daily heat record as people all over the Puget Sound region donned their shorts and sandals and experienced one last taste of summer-like weather.

Residents of the greater Puget Sound region have already been feeling the transition to fall with a shift down to lower temps and more clouds last week. But Friday marks the official end of summer, with the autumnal equinox on the calendar.

Fall doesn't technically start until Sept. 21, but it's arriving early this year as a front moves into the region this weekend. KNKX weather expert Cliff mass says it'll bring cooler temperatures and rain.

The eerie tinge to the air that deposited showers of ash in many areas of the Puget Sound region Tuesday seems to be subsiding. KNKX weather expert Cliff Mass says the worst of the smoky skies is over, pushed out by the approach of an upper level trough and cooler air moving in from the ocean.

It’s been a hot summer in the Pacific Northwest, and this Labor Day weekend won’t change that trend at all.

“It's going to be warm and dry,” says KNKX weather expert Cliff Mass, who teaches atmospheric sciences at the University of Washington.

Lots of sunshine and warmer temperatures are in the forecast all over the Puget Sound region. Once again, the mantra is “no rain.” And if you’ve been feeling like this has been a very dry summer – you’re right.

KNKX weather expert Cliff Mass says he’s sure we’ll at least tie the record for the driest summer in Seattle history, going all the way back to 1914.

Cloudy weather and milder temperatures have come back to the Puget Sound region recently.  We’ll have partly cloudy skies, no rain and temperatures in the mid-70s this weekend.

But come Monday, skies will clear over most of the region, just in time for the total eclipse.

Seattle's weather is about to revert to its more normal, pleasantly mild and occasionally moist summer pattern.

Rain in the weekend forecast should wash out the gritty smoke from British Columbia's wildfires that has plagued the region for more than a week now. The precipitation will also put an end to the long dry spell the city has experienced.

The National Weather Service issued an excessive heat warning for western Washington and Oregon Wednesday and said the highs in Seattle on Thursday could hit 95 (35 Celsius) while Portland could reach 105 (40.5 Celsius).

Seattle’s above-normal temperatures have been tempered somewhat by a grimy layer of smoke from British Columbia’s wildfires that moved in Tuesday. The influx has made air quality in and around the Emerald City worse than Beijing’s.

Even as the air cools a bit over the weekend, the temperatures will stay far above normal, with the haze dissipating only somewhat and quite slowly, says KNKX weather expert Cliff Mass, a professor of Atmospheric Sciences at the University of Washington.
