Look for a dose of sunshine this weekend, before gray returns

Expect the clouds to burn off later today, but you'll have to wait until Saturday for the really nice weather, says Cliff Mass, professor of Atmospheric Sciences at the University of Washington and KPLU's weekly weather expert.

Typical June weekend? Clouds, burning off late in the day

Don't expect to see much sunshine on Friday, as clouds and a weak front move through western Washington. In fact, brief episodes of drizzle are possible.

But, the sun could peak through at the end of the day, says Cliff Mass, professor of Atmospheric Sciences at the University of Washington. And that reflects a typical June pattern, he says.

Glimpses of sunshine this weekend, then chance of 80 next week

If the clouds and showers seem dreary, fear not: warm and sunny days lie ahead, says weather expert Cliff Mass.

Friday will start off with more of the same: “A lot of low clouds, but those will be burning off by mid-day,” says Mass, professor of Atmospheric Sciences at the University of Washington.

By Friday afternoon, temperatures will near 70, says Mass.

“But unfortunately, a weak weather system is approaching us,” says Mass, adding the system will likely arrive Saturday afternoon.

Mass: Some rain, some sun this Memorial Day weekend

Rain showers will be coming and going this weekend. That's the big picture, but Cliff Mass, professor of Atmospheric Sciences at the University of Washington, says the weekend won’t be a total washout.

“Memorial Day weekend is generally not the best,” he says. “We have a really nice period sometime in the early to mid-May most years, and we’ve had it.”

Now, Mass says, we’re starting to see the infamous “June gloom syndrome,” which he says involves “a lot of low clouds and sprinkles.”

If you liked the light rain falling this morning, you'll get a bit more on Saturday, and possibly Sunday morning, says Cliff Mass, professor of Atmospheric Sciences at the University of Washington.

On the other hand, if you're looking for some good outdoor times, Mass says we should dry out Sunday afternoon.

All you need is a quick look out the window to see a gorgeous day in store for Friday, with none of those morning clouds we've been seeing all week.

The day is the last “almost perfectly sunny and warm” day we’ll see this weekend, says Cliff Mass, professor of atmospheric science at the University of Washington.

"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."

Coming soon to Puget Sound area: 'Extraordinarily warm period'

Sick of the dreary weather? Fear not—a big change is coming, says KPLU weather expert Cliff Mass.

“The cold and rain is going to turn into warmth and sun pretty soon,” says Mass, a professor of atmospheric science at the University of Washington.

Cliff Mass investigates landslides, finds possible culprit

Keith Seinfeld — Fri, 12 Apr 2013 16:33:58 +0000

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?

Cliff Mass: How video game graphics could help save lives

What does a weather guy know about video games?

Cliff Mass has watched his kids play them plenty, and they gave him an idea that could help save lives.

“Some of these games have superb graphics. They have weather in them, even—storms and windstorms, and rain, and damage from storms,” says Mass, a professor of Atmospheric Sciences at the University of Washington.

Those sophisticated graphics gave him a thought: What if we used them to simulate exactly what the forecast is predicting?

Weekend forecast: Warm April showers to melt snowpack

Keith Seinfeld — Fri, 05 Apr 2013 16:12:37 +0000

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."

Glorious weekend, then drier-than-normal spring

Keith Seinfeld — Fri, 29 Mar 2013 16:05:33 +0000

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 or no snow, Northwest spring began months ago

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"

Keith Seinfeld — Fri, 08 Mar 2013 17:11:49 +0000

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.)
