Weather with Cliff Mass

University of Washington Professor of Atmospheric Sciences and renowned Seattle weather prognosticator/personality Cliff Mass has joined KPLU’s roster of commentators.

"Weather with Cliff Mass", our new five-minute feature hosted by KPLU's environment reporter Bellamy Pailthorp, airs every Friday beginning at 9 a.m. immediately following "BirdNote", and will repeat twice on Friday afternoons during All Things Considered. It is also available as a podcast on kplu.org

The nude cyclists at Seattle’s Fremont parade can look forward to comfortable summer temperatures on Saturday afternoon. And it might even be a bit too hot for runners at the Rock 'n' Roll Marathon, says KPLU weather expert Cliff Mass.

A weak front has passed through, says Mass, and the clouds and sprinkles are expected to subside in time for the summer solstice Saturday.

Friday will bear the worst of the weekend weather, says KPLU weather expert Cliff Mass, but don’t expect sunshine on Father’s Day.

The rain returned on Friday with a “fairly good drenching” — “the first substantial rain” in nearly two weeks — and the clouds are expected to stick around for most of the weekend, Mass said.

It appears the infamous June Gloom will spare us — at least for now.

“Normally this month, we have June Gloom: cloudy skies, temperatures in the 60s. But this year, it’s been unusually nice, [with] temperatures above normal and extraordinary amounts of sun,” Mass said.

It’s time to get out the sunscreen and summer clothes.

KPLU weather expert Cliff Mass says we have a beautiful weekend ahead of us.

Well, it's complicated.

The forecast for our long holiday weekend starts wet, then dries out, then gets downright motley as we move into prime barbecue territory.

The weekend curse is back, according to KPLU weather expert Cliff Mass.

After a week of unseasonably warm and dry weather, reaching up into the 80s more than once, temperatures are set to drop about 10 degrees on Friday, and step down another 10 or so over the weekend.

“First things first,” said KPLU weather expert Cliff Mass. “For Mother’s Day, it looks good.”

Mass predicts sunny skies and temperatures of at least 70 “and maybe even into the low 70s” for Sunday.

But before then, there’s some rain to get through.

It seems the curse of the wet weekend is upon us again.

This week's unseasonably hot transition from April to May is giving way to much cooler temps and heavy rain on Saturday and Sunday, says KPLU weather expert Cliff Mass.

It comes on the heels of a gloriously sunny and hot work week.

Don’t put your parkas away just yet. 

It’s classic April weather this weekend with lots of showers but plenty of sunbreaks, too, according to KPLU weather expert Cliff Mass. 

Saturday, in particular, is going to be nice, says Mass, who teaches atmospheric sciences at the University of Washington.

If you’re planning any outdoor fun this weekend, Sunday’s your best bet, says KPLU weather expert Cliff Mass.

The famous Puget Sound convergence zone has been dumping rain in the greater Seattle area, with some places in the foothills of the cascades getting as much as 4 inches in the space of just six hours on Thursday afternoon. Mass, who teaches atmospheric sciences at the University of Washington, says there will be a break from that today, but not for too long.

Get out your shades and sunscreen: this weekend promises to be mild and very sunny, says KPLU weather expert Cliff Mass.

“It’s gonna be quite good,” said Mass, professor of atmospheric sciences at the University of Washington.

This weekend's rain caused parts of western Washington to see the wettest March on record as was predicted by KPLU weather expert Cliff Mass

"My lawn has turned into a carpet of moss and my deck is now green," Mass said on Sunday.

Friday's steady rain is contributing to what may become a record-breaking March for total rainfall in many places in the Northwest.

KPLU weather expert Cliff Mass says a wet front is coming through western Washington.

Spring has officially arrived, but warmer temperatures have not. Those warmer days lie ahead, but first we’ll have to get through a cool and wet weekend, says KPLU weather expert Cliff Mass.

Just when you thought spring had arrived in the Pacific Northwest, winds and wet weather are sweeping in.

We're in for another wet weekend, says KPLU weather expert Cliff Mass — but not without sun breaks.

After a record-breaking week of strong rain, Friday will bring a bit of reprieve. But the rain will return this weekend, even in the mountains, says KPLU weather expert Cliff Mass.

Still, there is good news: come next week, we’ll start transitioning into spring.

Soak in Friday’s sun and spring-like temperatures while you can, because they won’t stick around this weekend, says KPLU weather expert Cliff Mass.

Mass says snow is once again in the forecast for parts of western Washington.

The weekend forecast includes chances of snow, but nothing's for certain, says KPLU weather expert Cliff Mass.

"This is a hard one," said Mass. “There’s a lot of uncertainty here. I’ll tell you that right in the beginning.”

We’re getting the “weather we need,” so get ready for a wet and windy weekend, says KPLU expert Cliff Mass.

“Our water supply was well below normal,” said Mass, who teaches atmospheric sciences at the University of Washington. “Very rapidly, the snowpack is getting replenished in the mountains. The reservoirs are filling. And by the end of this week, I don’t think we’ll have to worry water for this summer or the coming fall.”

Just how much longer will this cold snap last?

“Only through the end of the weekend,” said KPLU weather expert Cliff Mass.

And the Seattle area likely won’t see snow before it’s over.

Olympia and points south could see a dusting of snow on Thursday night, but not enough to accumulate, says the National Weather Service.

The region might see more snow on Saturday, but exactly where and how much remain unclear, according to KPLU weather expert Cliff Mass.

“You can do anything you want over this weekend,” said KPLU weather expert Cliff Mass. “No storms, no nothing. And in fact, there will be some sun.”

Things will dry out late Friday, and temperatures will reach the mid-40s in the lowlands, said Mass. Saturday will add partial sunshine.

Come Super Bowl Sunday, there will be “no weather around here to be worry about,” said Mass. Things will be fairly dry for most of the day.

“Then things get more interesting,” he said.

Start planning your weekend. The forecast looks sunny, dry and warm, says KPLU weather expert Cliff Mass.

“Temperatures in the lowlands will reach lower 50s in some places. And some spots along the coast might even see lower 60s,” said Mass, who teaches atmospheric sciences at the University of Washington.

Ready for spring? Head to the coast or the top of a mountain, says KPLU weather expert Cliff Mass.

The reason: “The diabolical ridge is over us right now,” says Mass, who teaches atmospheric sciences at the University of Washington.

Global warming behind the recent polar vortex? Nonsense, says KPLU weather expert Cliff Mass.

“There’s really no basis for this,” said Mass, adding there's a lot of misguided hype on both sides of the issue.

This weekend will bring heavy rain, strong winds and snow in the mountains, says KPLU weather expert Cliff Mass.

“You can expect everything this weekend,” said Mass, who teaches atmospheric sciences at the University of Washington.

The year 2013 was “kind of a boring year,” says KPLU weather expert Cliff Mass. “Nothing really extraordinary.”

We saw average temperatures, no extreme storms and not much snow — much less excitement than Mass had hoped for. Even the few tornados we saw were not unusual, he says.

Still, Mass admits, “we had some interesting details.”

Aaron Brethorst

Go out and play this weekend, and don’t worry about getting wet, says KPLU weather expert Cliff Mass.

"There's going to be no rain, no snow, no nothing on Saturday and Sunday," said Mass, who teaches atmospheric sciences at the University of Washington.

"'In fact, shocking: we're going to have sun,” he said, “no doubt about it, because of the strong ridge of pressure over us.”

Dan Pickard

If you got caught in the fog on Thursday, you were not alone. KPLU weather expert Cliff Mass says he, too, got a bit lost in the muck on his way to the airport. 

Good News: No Burn Ban

The fog that lingered near Tacoma and Lynnwood will melt away soon, says Mass, who teaches atmospheric sciences at the University of Washington.

And there's a 50 percent chance of rain in the forecast, which is probably why there is no burn ban at the moment.

"There's a weak front approaching," said Mass, adding the front will cause the fog to dissipate.
