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.

A small storm of drizzle spoiled Seattle’s chances to break what KNKX weather expert Cliff Mass viewed as a significant record.

Thursday morning’s precipitation was just enough to be considered a "trace" of rain and cancel the chance for a rain-free July. But there is still a chance to continue a dry-day streak.

Drizzle and light showers fell in a few places this week, especially in the south end of the Puget Sound region. But for most of the region, including Seattle, rain has been missing for more than a month.

KNKX weather expert Cliff Mass says there’s a good chance the emerald city will break a record with this dry spell.

There will be plenty of sunshine and opportunities for enjoying the outdoors this weekend, especially in and around Seattle. KNKX weather expert Cliff Mass says the city "is known to have the best summer in the United States."

We'll have highs in the upper 70s for Friday and Saturday for the whole region, with no precipitation and hardly any clouds.

If you have been enjoying the warm sunny skies of Seattle lately, you’re not alone. So many of us revel in the long stretches of dry weather that are so favorable for outdoor activities.

This weekend will offer more of that wonderful weather, with just a few morning clouds that should burn off in the afternoons.

“The bluest skies you’ve ever seen are in Seattle” — so goes the corny Perry Como TV tune from the late '60s. But it’s still true nearly 50 years on. The weekend forecast includes more of that great weather – only sullied by a few clouds coming in from the ocean over the weekend. And the blue skies will be back in time for July 4th festivities.  

He says Friday’s weather will be “perfect – sunny, absolutely dry, highs in the lower 80s. So, it’s going to be the warmest day of the weekend – so, really wonderful.”

If you like heat, this is the weekend for you in the Pacific Northwest. Just in time for the official start of summer, temperatures are about to zoom all the way up to near 90 degrees.

“And I think some people will see record temperatures this weekend,” said KNKX weather expert Cliff Mass, who was quick to clarify that these would only be for a single day in question, which are "not such a big deal. “

Do you know the term "Juneuary"?  That’s what many people living in the Pacific Northwest call this time of year because of a combination of factors that make the month of June less than spring-like. There’s the typical low cloud cover, shared with the rest of the coast all the way into Northern California and often referred to as "June Gloom." And then there are periods of heavy rain that sometimes hit unexpectedly. That’s what happened on Thursday, when an atmospheric river hit the coast. (You can learn more about that by listening to the podcast of this conversation.

Keep those layers handy and also a rain poncho or parka if you’re doing anything outdoors this weekend. It’s typical June weather in the Northwest, which had a nice stretch of beautiful weather lately, but has now entered a period of mixed weather that some people like to call "Juneuary."

The temperatures have dropped and there are lots of clouds around. KNKX weather expert Cliff Mass says this is typical for the time of year we’re in.

Friday: Mixed And Cool

Keep those layers and light parkas handy. The weather this weekend in the Pacific Northwest offers a normal mix of cloudy skies, drizzle and temperatures ranging from early morning lows in the 50s to highs as warm as mid 70s next week.

KNKX weather expert Cliff Mass says there was a weak cold front coming in off the coast, cooling things down early Friday.

Get out your sunscreen, shades and maybe power up a grill or three. The weather for Memorial Day weekend in Western Washington will be extremely pleasant for most people.

“Warm again, temperatures getting up into the 80s before the weekend is over,” said Mass, who teaches atmospheric sciences at the University of Washington.
