Extended interview with Cliff Mass

"We have an extraordinary weekend ahead," says KPLU's weather expert Cliff Mass. "And In fact, it's probably not going to rain until at least next weekend as well."

Friday will warm up to lower 70s with “no precipitation anywhere,” says Mass, a professor of atmospheric science at the University of Washington. “And it just cranks up over the weekend."

Mass: Back to cooler and wetter days, but be thankful for normal

Be thankful for normal, even if it's not sunny and warm, says Cliff Mass, KPLU's weather expert and a professor of Atmospheric Sciences at the University of Washington.

"The interesting thing about this spring is it's been really normal. It's really normal to have some periods where it's above normal and below normal," says Mass, adding he's not quite a prophet of doom; maybe the "prophet of deterioration."

Cliff Mass investigates landslides, finds possible culprit

There's more rain in the forecast tonight and this weekend -- with some real downpours expected Saturday in the fabled "convergence zone" of south Everett.

The rain should arrive after 4pm today, for much of the Puget Sound region, says Cliff Mass, professor of Atmospheric Sciences at the University of Washington (and KPLU's weekly weather expert).

Could that mean more landslides, like the ones that have derailed trains south of Everett, or pulled away a home on Whidbey Island?

Weekend forecast: Warm April showers to melt snowpack

Those showers that blew in on Thursday will keep blowing our way through Sunday, says KPLU weather expert Cliff Mass, a professor of Atmospheric Sciences at the University of Washington.

“And that’s a big change,” he says. “The first real rain that we’ve had in a long time happened last night (Thursday), where a lot of people got about a half an inch. But it’s not the end."

And, because it's been warmer rain, the snowpack in the mountain passes is melting quickly, he says, losing about 20 inches.

Mass says another front will arrive late Friday.

Glorious weekend, then drier-than-normal spring

First, the good news: enjoy this weekend, which is shaping up to be wonderfully mild and full of sunshine with highs in the 60s across Western Washington.

After that, be ready for plenty of twists and turns. April is the month of frequent weather changes, says Cliff Mass, professor of atmospheric sciences at the University of Washington.

The two hallmarks of April:

Snow on the third day of spring has some people wondering: what gives?

Well, actually, spring here began a long time ago, says KPLU weather expert Cliff Mass.

“The problem we have here in the Northwest is spring lasts too long,” says Mass, professor of Atmospheric Sciences at the University of Washington.

Thank the rain shadow, get ready for Gore-Tex weekend

Expect more of what we've been seeing all week — "clouds, showers, breaks," says KPLU weather expert Cliff Mass, a professor of atmospheric science at the University of  Washington.

"Wear Gore-Tex or some raincoat," says Mass, adding, "There will be plenty of breaks."

The temperatures will remain mild until Saturday evening when colder air will head into the region. The new front will bring some welcome snow to Cascade ski areas, says Mass.

"The freezing level will drop from 4,000 to 5,000 feet, to 1,000 – 1,500 feet," he says. "They can easily get 2 to 6 inches."

Fog burning off leaves classic "Northwest mild"

Fog burns off, leaving sunshine in its wake, this weekend. That's the forecast for Friday and Saturday, says Cliff Mass, professor of Atmospheric Science at the University of Washington and KPLU's weather expert.

Fires, on the other hand, leave us with smoke, and in this week's weather conversation, Mass explains how that can affect the flavor of wine. (Click the "listen" button above, and check-out Mass' blog.)

Seattle's boring winter gets zesty this weekend

It's nothing like the major storms across the midwest and eastern U.S., but western Washington is tasting a little bit of winter, finally.

"After one of the most boring winters that I can ever remember, we are going to be getting heavy rain, good snow. We'll be getting some winds gusting up to 30 to 50 miles per hour, and big waves along the coast," says KPLU weather expert Cliff Mass, a professor of Atmospheric Sciences at the University of Washington.

Clouds come and go this weekend, with Sunday looking nicer

Morning clouds should give way to afternoon sunshine Friday in many Puget Sound neighborhoods. But some unpleasant weather is headed our way for Saturday, especially in the Seattle-to-Everett area.

That's the immediate forecast from KPLU weather expert Cliff Mass, a professor of Atmospheric Sciences at the University of Washington.

  [Feb. 11th Update -- Audio problem fixed]

While the Northeast struggles with a massive snowstorm, the same forces are keeping it mild on the West Coast, says KPLU weather expert Cliff Mass, a professor of Atmospheric Sciences at the University of Washington.

What are those forces? High pressure and low pressure. Okay, it's more complicated than that, but there is a high pressure "ridge" over the west, which forces a "trough" toward the east.

Damp, not too cold -- a classic NW weekend

For a weather forecaster, this weekend is looking "pretty boring," says Cliff Mass, professor of Atmospheric Science at the University of Washington and KPLU's weather expert.

Some showers will blow through, but nothing dramatic. The mountains should get a little snow, but not enough to snarl traffic on the passes. Sunday should be a bit drier.

And what about snow in the city this winter?
