Weather with Cliff Mass

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.”

Western Washington winters are relatively mild. We rarely see snow in the lowlands. But when it does snow, things freeze over in a hurry. 

Why does that happen? It has to do with our mild temperatures, says KPLU Weather expert Cliff Mass.

Uncertainty shrouds forecast models for the Thanksgiving weekend, says KPLU weather expert Cliff Mass, but two things are for certain: there will be snow—possibly in the lowlands, and it will get much colder. 

But first, the good news: neither of those things will have started as people head out of town on Wednesday, says Mass, who teaches atmospheric sciences at the University of Washington and pens a popular blog

It may be chilly out there, but it’s also unusually dry for this time of year, says KPLU weather expert Cliff Mass.

“It’s really startling,” said Mass, who teaches atmospheric sciences at the University of Washington. “We’re in a most amazing pattern. I mean, this could be the wettest, stormiest time of the year, and it’s going to be basically dry over the next few days. In fact, I think probably the next week, we’re not going to see any precipitation.”

We may see a few clouds Tuesday and Wednesday, but then we’ll have wonderful weather for Thanksgiving, says Mass.

Batten down the hatches and get ready for a cold and gusty weekend, says KPLU weather expert Cliff Mass.

Mass says a major system in the Gulf of Alaska is headed our way, and will hit the lowlands with strong winds and the mountains with snow.

"Today is the calm before the storm," says KPLU weather expert Cliff Mass.

The first big storm of the season will hit the Northwest on Saturday, and it's expected to produce winds strong enough to cause power outages and trigger snowfall in the mountains at elevations low enough to cover the passes.

Why did we have such a long stretch of fog? Blame the inversion, says KPLU weather expert Cliff Mass.

Foggy days in the fall aren’t uncommon in the Northwest, but the recent long stretch—the so-called “Fogtober” and “Fogmageddon” that Mass said will finally leave us Sunday—is quite rare.

Fogmageddon will end on Sunday, “pretty much guaranteed,” says KPLU weather expert Cliff Mass.

The very dense fog hanging around the region this morning bodes well for a long sunny day ahead, and the week will continue with that pattern, says KPLU weather expert Cliff Mass.

“As I mentioned before, that’s a tremendously good sign,” said Mass, who teaches Atmospheric Sciences at the University of Washington. He says the densest fog usually means the sunniest afternoons.

“The clouds, the cold air, that low foggy layer is actually very shallow today and I expect it to burn out much quicker than it has in the past,” he said, predicting that it should be completely sunny outside by 11 this morning, with temperatures going up to around 60.

Late September and early October are the foggiest time of the year in the Northwest, according to Cliff Mass, KPLU weather expert and professor of atmospheric sciences at the University of Washington.

Why is that? Mass says fall in the Northwest brings all the right ingredients.

The clouds and light rain that have been darkening skies in southern King County should give way to dry weather and partly cloudy skies later today. And that’s just the first glimmer of nice fall weather in a week that promises to bring lots of mid-October sunshine.

That’s according to KPLU weather expert Cliff Mass, a professor of atmospheric sciences at the University of Washington.

“By this afternoon it’ll be partly cloudy,” Mass said, and “completely dry in all of western Washington.”

The first frost of the season hit the northwest Friday morning on both sides of the mountains, but skies will be sunny for much of the weekend.

Enjoy it while it lasts, since it will turn rainy again on Monday, says KPLU weather expert Cliff Mass, a professor of Atmospheric Sciences at the University of Washington.

Cliff Mass says his jaw dropped when he looked at the satellite image of an approaching system.

That wet front due to arrive on Saturday is “so extensive, so wide, and so intense” for a September storm, says Mass, KPLU weather expert and professor of Atmospheric Sciences at the University of Washington.

Good news: summer's not over just yet! There are still some blue skies left in the forecast, says KPLU weather expert Cliff Mass. 

"About two and a half days, to be exact," says Mass, who teaches Atmospheric Sciences at the University of Washington.

The worst is over is now, says KPLU weather expert Cliff Mass.

“The heaviest rain, and certainly the lightning is over for the time being,” said Mass, professor of Atmospheric Sciences at the University of Washington.

And the good news, says Mass, is that things will get better—eventually.
