Mass: 2013 Was 'Kind Of A Boring Year,' But With 'Some Interesting Details'

Tim Durkan

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.”

Lifting Fog, Persistant Ridge And Mysterious Cloud Patterns Over Seattle

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.

Jennifer Strachan

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.

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

Mass: 'Most Amazing Pattern' Defies Tradition, Brings Dry Spell

Rob McNair-Huff

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.

"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.
