Weather with Cliff Mass

People in the Pacific Northwest have been experiencing a bit of a roller coaster ride weather-wise lately, with temperatures spiking up and down in a manner that KNKX weather expert Cliff Mass says is quite typical for late May. The ride will go uphill this weekend to a predicted high of about 80 degrees on Sunday, just in time for Mother’s Day.

“The weekend is going to be wonderful,” Mass says. The clouds will dissipate later in the afternoon Friday, he says, as temperatures climb to the upper 60s and high pressure builds. Mass says it will stick around for a while.

Here are some upsides to cloudy weather: Cloud cover creates a soft light that's great for photographers. It’s harder to get a sun burn. And clouds can be really fun to look at.

Many of us may need a few reminders that clouds aren't so bad as we enter what could become an extended period in which low clouds and cooler temps dominate in the greater Puget Sound area.

Folks around the Puget Sound region enjoyed a toasty week with temperatures in the 70s starting Tuesday. They even hit the low- to mid-80s in many places in western Washington.  

But the classic northwest “sandals-and-socks” people are now wearing their socks again.

After nearly three weeks of wet weather that was making it look like this month might shape up to be one of the rainiest Aprils on record, sunshine is on its way to the Pacific Northwest. KNKX weather expert Cliff Mass says there’s one last rainy stretch to get through late Friday, but after that, real spring warmth and strong sun is on the way.

If you were hoping April showers would hold off this weekend, don’t hold your breath. Be ready for more of the cool, wet weather that has been persisting in the Pacific Northwest in recent weeks.

‘April showers bring May flowers,’ or so the saying goes. Like Groundhog Day or dozens of sayings you can find cataloged in a Farmer’s Almanac, it’s part of the weather-related folklore that’s been passed down for generations. They hold some truth.

But most meteorologists prefer more scientific observations. For long-term forecasting, the ENSO - or "El Niño Southern Oscillation" - provides some of the most reliable guidance on what kind of weather to expect in winter.

A predominantly cloudy period has dominated in the greater Puget Sound region this past week, with intermittent showers and mostly mild temperatures. That pattern is expected to continue into next week, says KNKX weather expert Cliff Mass – with one exception.

When you think of spring, visions of daffodils and cherry blossoms under warm, sunny skies may come to mind. Turns out the more typical aspects of this season, meteorologically speaking, come from the unstable atmosphere, which produces lots of wet and showery, cool weather.

The vernal equinox marks the official start of spring. That starts Tuesday. But for most folks in the Pacific Northwest, it feels like spring has already arrived.

Time to get out the short sleeves and sunscreen. Warm winds from the south and east are going to push the mercury to nearly summer-like levels in western Washington this weekend, says KNKX weather expert Cliff Mass.

The record cold, wet and snowy weather of late February has subsided. Residents of western Washington can look forward to a classic Northwest weekend, with mild temperatures, partly cloudy skies and just a chance of rain.

“It’s going to be a fairly dry weekend,” said KNKX weather expert Cliff Mass, a professor of atmospheric sciences at the University of Washington.

Don’t put away your hat and gloves. It’s going to stay cold for the next week or so and there will be snow on Friday. That much is certain, says KNKX weather expert Cliff Mass. The rest of the weekend forecast is tricky.

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.
