It happens every year. As the summer wanes and fall sets in, people start thinking about the coming winter and how much snow we’ll get, especially in the mountains.

In the Pacific Northwest, that can mean dreams of snowy ski slopes or how much snow pack we’ll have to fill reservoirs and water dry streams when the spring melt comes.

Fall got off to a glorious start in most of western Washington, with the first week offering consistently clear blue skies and mild temps in most places, most days.

That pattern continued Friday morning, with the promise of more clear weather through Saturday.

Friday is officially the final day of summer, marked by the fall equinox. Showery weather is ushering in the transition in western Washington, though it’s expected to make way for some glorious conditions next week.

Heavy rain hit many parts of western Washington overnight and into Friday morning – a change welcomed by many, after what was reportedly the state’s third-driest and third-hottest summer of the century.

The good news is that air quality has improved dramatically, and we no longer have to worry about breathing in smoke from wildfires. The bad news is that the clouds and showers moving in with a rapid cooldown this weekend are just the beginning of what will likely be several months of cooler fall weather.

“Summer is over,” said KNKX weather expert Cliff Mass.

After weeks of air quality issues throughout from wildfire smoke and high temperatures nearing 90 degrees, changes are coming. We've been seeing smoke clearing out and cooler temperatures rolling in over the last week.

A cloudy start to Friday with slightly cooler temperatures signaled a return to more normal conditions in the Puget Sound region after a week in which air quality reached its worst levels ever for a 24-hour period, measured by the particulate matter in the air.

Enjoy the warmth while you can. After a long string of warmer-than-usual, sunny skies in the greater Puget Sound area, cooler temps and rain are in the weekend forecast.  

KNKX weather expert Cliff Mass says Friday will be the last really warm day for a while.

Cloudy skies, cool marine air and patches of drizzle greeted folks in the Puget Sound region Friday morning for a second day.

The filtered light and soft cloud layer signaled a return to more typical weather after nearly three months of dry skies and above-normal temperatures. The days of temperatures in the 90s are done, says KNKX weather expert Cliff Mass, a professor of atmospheric sciences at the University of Washington.

It’s been hot in the Pacific Northwest, with nearly two weeks of clear blue skies and temperatures near 90 degrees. There has been no rain in sight, just a glorious backdrop for mountain and water views, perfect weather for swimming or running through sprinklers.

Expect more of that over the weekend and through Monday at least, says KNKX weather expert Cliff Mass, a professor of atmospheric sciences at the University of Washington.

A mild and cloudy Friday will give way to gradually warmer temps, with sunny skies by Sunday and hot weather in the 90s Monday and Tuesday.

That’s all we’re telling you about the specifics of the forecast this week because we have something to celebrate. It’s been 5 years since I started hosting the show, so we thought it would be a good time to pull back the curtain on what we’re aiming for with the segment and why.

Where there’s heat, there is often fire. The fire risk on both sides of the Cascade Mountains is high in the week ahead, as temperatures will be zooming up as high as 90 degrees after a rather dry June.

If the cloudy and sometimes dark skies of late have been hard on you, just hang on a bit.  KNKX weather expert Cliff Mass says “an improving trend” is ahead. 

Residents of the Pacific Northwest should soon be enjoying a long stretch of sunny skies. They have even  inspired music - like the 1969 TV tune about “the bluest skies you’ve ever seen” are  in Seattle.

Cloudy skies and cooler-than-normal temperatures will dominate in the week ahead, a continuation of the weather pattern many refer to as “June gloom” for the gray or “Juneuary” when the cloud cover comes with cold air.

It’s the kind of ‘blah’ weather that can disappoint people who expect blue skies in June. But the gray, at least, is pretty typical. KNKX weather expert Cliff Mass says it’s going to stick around for a while.

Cooler weather has settled in all around the Puget Sound region after a rapid drop in temperatures that started Wednesday night.

KNKX weather expert Cliff Mass says there will be a bit more sun peeking through the clouds in the days ahead. But overall, summer is starting with a mellower feel than the recent heat wave that pushed temps into the mid- and upper-80s.

Last week brought heavy rain showers with cooler temps and even some snow to the mountains in places. But that’s changing as high pressure builds over the region, allowing a big warmup just in time for summer solstice celebrations this weekend and Father’s Day on Sunday.

This May, people living in the Puget Sound region experienced a lot of warmth and a month so dry, it matched the record for the driest May on record. The dry spell actually began in mid-April, so it lasted about 6 weeks.

That was changing Friday as clouds rolled in and skies began to darken. KNKX weather expert Cliff Mass says folks here had better keep their rain gear in reach.

Cooler temps, clouds and wind gusts ushered out the record warmth Seattle area residents experienced in May, which also tied a record for lack of rain. All that changed on Friday as marine air surged in and cooled things off.

The mix of sun and clouds in the Memorial Day weekend forecast should not come as a surprise to people living in the greater Puget Sound region.

Late May weather here often brings a tantalizing mix of sunny warmth with clouds that can quickly yield to cooler skies as drizzle or cool marine air pushes in.

But the weekend forecast should be mostly drizzle-free, says KNKX weather expert 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.
