The cold temperatures are gone, for real

Awww - we're all ready for a little sun and warmth.

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.

We're stuck! Expect 10 days of off-and-on rain, even some snow

Spring is in the future, but so is the rain.

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."

Forecast: Showers ahead (but revel in the spectacular clouds)

Lenticular clouds make Mt Rainier's classic crown
Mike Kelley Flickr

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.

Enjoy Sunday, possibly glorious weather ahead

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.

Snow? Looking likely for Sunday, but only a dusting for most

Just a dusting for most, but there will be some snow.
Shannon Kringen Flickr

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.

Soggy start to weekend, but some nice skiing ahead

Not for wimps: Now, that's what a real storm front looks like ... on the plains of Nebraska.
Michael Cornelius flickr

It's too wimpy to call it a storm, but wind and rain will dominate through tonight and tomorrow, says KPLU weather expert Cliff Mass.

The winds will be hard to miss along the Washington coast, getting up to 60 mph. But, as Mass explains, the coastal mountains tend to cut down those winds by the time they reach Puget Sound, leaving us with merely blustery conditions.

By Sunday, it should dry out, and skiers will find a lot of fresh snow waiting for them in the mountains. Next week appears to offer more mild temperatures with occasional rain showers.

Light rain falling, but can we trust those weather 'models'?

Rain and more rain ... back to normal.
Kevin Dooley Flickr

You can call it light rain or "the good rain" (after local author Tim Egan), but either way, it’s the signature of the great Northwest. And it's here through much of the weekend.

That's the forecast from KPLU expert and UW professor Cliff Mass.

Forecast calls for sunshine with subtleties

There will be sunshine.

Today’s forecast calls for sunshine, says KPLU’s weather scientist Cliff Mass. And, as scientists are bound to do, he also notes some interesting details not as obvious as the sun in the sky.

“We may have a lot of sunshine but there are a lot of subtleties going on in the next few days that are worth talking about,” Mass said.

Heading outdoors? Saturday's the day ... plus how the windstorm created a geyser at Ivar's

Winds and a high tide sent a surge of water this week toward this Ivar's Restaurant in Mukilteo -- strong enough to erupt through the floorboards.

The weather is so normal, it's almost boring, at least to atmospheric scientists like the UW's Cliff Mass.

"Unfortunately, next week, we just have one minor system after the other coming through," says Mass. "No real severe weather. No big snowstorms or windstorms."

With the morning fog burning off Friday, Mass sees sunshine through this afternoon.

Rain, big winds in forecast; Cliff Mass: 'We messed up'

A truck drives around a downed tree in Tacoma, Wash., on Friday. Thick ice brought down trees and power lines in the region overnight, following two days of snow and ice storms.
The Associated Press

The big melt continues all day and through the evening, as temperatures settle into the 40's.

KPLU and UW weather expert Cliff Mass says "it should feel quite warm" and generally stay above freezing for the next few days.

Given what's already on the ground – and with heavy rains tonight – it's a recipe for a mess.

Snow? Probably yes, for most of western Washington

A vision of things to come ...
Adam DeClercq Flickr

But not too much. 

"It's not going to be the big snow-storm," says KPLU weather expert, and UW professor, Cliff Mass.

The areas most likely to get a couple inches of snow are the so-called "convergence zone," between north Seattle and Everett, and in the Bellingham area. For everyone else, Mass says it will be "hit and miss" depending on so many factors that it's hard to generalize.

Mild, maybe some sun, and then back to dry, dry, dry

Dave Morrow Flickr

"No major storms, no major weather, as far as I can see."

That's weather expert Cliff Mass's summary for western Washington. Mild, perhaps a shower or two Friday night, and a chance of sun on Sunday.

Rain, rain and more in the forecast - but, embrace the weather and you'll be fine

Count the raindrops, go Singing in the Rain, or join the "surface data revolution" to beat the winter blues. It will be rainy, cold and stormy in the week ahead.

"It was like Palm Springs around much of the Northwest" recently, says KPLU's weather man, Cliff Mass. But that will be shifting soon. 

"Unfortunately, we're about to make a major shift into a much rainier pattern - a much more normal pattern."

Dry December continues, but inversion is breaking up

Dry and cold, often means frost
Daveybot flickr

A drought in December? It's been record dry this month, so far, says KPLU weather-meister Cliff Mass. In the meantime, we'll get a few showers, and possibly a glorious Saturday.

The off-shore pressure "ridge" is still there, keeping all the storms away from the Northwest. But, it's weakening, and the "inversion" -- which led to stagnant air, burn-bans, and so much fog -- appears to be breaking up.

Balmy in the mountains, giving way to a little rain

An inversion traps cold air and fog in the lowlands, while sunshine reins on the hills above Bellevue, Wash.
Peter Brenda

If you had the time to take a hike today, or hit the ski slopes, you'd find it's maybe 20 or 30 degrees warmer when you climb above 3,000 feet, says KPLU weather expert Cliff Mass.

That's because the atmospheric inversion is extreme today, trapping cold air in the cities of Puget Sound-opolis, while the warm air is trapped above.

Mass says it won't last. A bit of rain will break up our unusual dry spell, starting late on Saturday. Then, on Tuesday, the inversion ends, as a storm starts to mix the air.
