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

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.”

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.”

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.

Most of the snow fell overnight while western Washington slept, and "the worst is over," says KPLU weather expert Cliff Mass. The metropolitan area of Seattle saw ¾-inch to 3 inches of snow while areas north of the city saw more.

“But for most people, they’ve seen the bulk of what they’re going to get," said Mass, who teaches atmospheric sciences at the University of Washington.

It’s not always easy to predict lowland snow in the Pacific Northwest, but the latest weather models confirm snow is coming on Friday, says KPLU weather expert Cliff Mass.

Snow in the lowlands may snarl Friday's morning commute, says KPLU weather expert Cliff Mass.

“Models are still suggesting that there will be extensive lowland snow on Friday morning, between roughly 1 to 2 a.m. and 10 a.m.,” said Mass, who teaches atmospheric sciences at the University of Washington, on his weather blog.

Our drier-than-usual fall is coming to a mild end as we return to the "old boring stuff," says KPLU weather expert Cliff Mass.

And that means a relatively dry weekend that’s much warmer than the last.

Shivering in the cold snap? The worst has yet to come, says KPLU weather expert Cliff Mass.

‘Colder Air than We’ve Had’

Temperatures will drop even more this weekend, says Mass, who teaches atmospheric sciences at the University of Washington.

“The coldest temperature of this event will occur Saturday and Sunday, and I expect Sunday morning to be ground zero for cold,” he said. "As the low goes by, cold air is going to be moving out—even colder air than we’ve had before.”
