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

The forecast for today and tomorrow calls for sun and low to mid-70s temperatures, says KPLU weather expert Cliff Mass. But, the sun and clear skies will give way on Sunday and Monday to clouds and temperatures at least 10 degrees lower.

Basically, we’re still transitioning into the “June gloom.”

You can blame a ridge of pressure over the Pacific for pushing a layer of cool, cloudy marine air over western Washington, says KPLU weather expert Cliff Mass.

The rumors of imminent warmth are confirmed, by KPLU weather expert Cliff Mass.

"The whole weekend is going to be extraordinary," says Mass, professor of atmospheric science at the University of Washington.

Today, KPLU's weather expert Cliff Mass and science reporter Keith Seinfeld touch on the forecast – cloudy through most of Saturday, then getting better through Monday – and then take up a common thread throughout NW weather history: grousing.

Here's a weather report from 1855 published in the Puget Sound Courier:

"Well, March went out, April came in, and with it, cold, wet, disagreeable weather, and a universal spirit of discontent, and a disposition to 'growl'"

"Throughout the entire month, and even up to this, the last day of May, it has been precisely the same, and some amongst us profess to be so thoroughly disgusted with the weather .... that they threaten to leave the Territory altogether."

Yet another weekend that beats the work-week, when it comes to sunshine--that's the forecast from KPLU weather expert Cliff Mass, of the University of Washington.

But, it won't exactly be warm and sunny.

April showers will dry out today, and by Saturday, most of western Washington should see sunshine. But, we're not so sure about Sunday.

If you've been enjoying sunshine and how the light plays off the blossoms or the water -- there's more in store this weekend. But, it's not "normal," says KPLU weather expert Cliff Mass.

"It's been drier than normal this month. From April first until now, we are over an inch below normal, in terms of rainfall. We have been warmer than normal this past week," he says.

That continues through Sunday, with temperatures reaching the lower to mid-60s.

A few scattered showers on Friday--and some puffy cumulus clouds--will dry out for Saturday.

"It should be a glorious day. And interestingly enough it should be warmer in western Washington than eastern Washington, which is not the normal situation this time of year," says KPLU weather expert and UW professor Cliff Mass.

The sunshine should stick around Sunday, but there's a bit of a debate among meteorologists over what happens Sunday evening and next week.

This March was Portland's wettest month ever, with a record-breaking 7.73 inches of rain. And, records fell throughout most of Washington last month, as well, reports KPLU weather expert Cliff Mass.

What happens when a river runs into a mountain?

An atmospheric river, carrying dense clouds of moisture from the tropical Pacific, has been colliding with our mountains, and all that moisture has been dropping like a waterfall.

It's true, says KPLU weather expert Cliff Mass, of the University of Washington. It will feel like spring from here on out.

We had clear skies starting this morning, and temperatures will approach 60 on Saturday, says Mass. Expect a few clouds on Sunday, but still a pleasant day.

Sure spring is coming next week, but KPLU's weather expert Cliff Mass says we'll be seeing plenty of rain and even some snow this weekend and it doesn't get any better for days to come.

Mass explains on his blog: "Last winter we were securely in La Nina conditions and the region experienced a miserable, cold, wet spring that lasted into mid summer.   Horror to all soccer and Little League parents.

"This winter we have also been in a La Nina and since early February we have been colder and wetter than normal, with snowpack surging in our mountains. Yes, it appears we are dealing with  the revenge of La Nina."

Weekend weather will be cloudy with showers off and on ... a pretty classic Northwest late winter forecast, says KPLU weather expert Cliff Mass of the University of Washington. Rain should arrive by dinner-time.

Watch for a bigger storm on Monday, particularly on the coast, where winds could hit 50 mph.

The clouds we've seen so far this week have been pretty interesting. Cloud watchers got a great show yesterday of "lenticular" clouds.

Mass says they look like stacks of plates -- and may have helped set off the UFO craze.

On his blog, KPLU weather expert Cliff Mass writes:

Sunday should be great....sunny, much warmer air...many will see the mid-50s.   A big ridge over us....   Plan to get outdoors!

 

In general, warmer temperatures are in store, beginning this evening, says Mass in his weekly weather conversation with KPLU. You can expect a little of everything on Saturday, before it clears out on Sunday.

Next week, Mass says it will be cooler and wet again, fitting with the La Nina pattern that's settled in place.

That's the forecast as of Friday morning, from KPLU and UW weather expert Cliff Mass.

"I don't know if you'll wake up to it, but Sunday morning into Sunday, during the day there will be some snow showers," says Mass.
