More Cold And Showery Weather This Weekend; Snow Possible On Sunday

Saturday should provide a respite from the bout of rain and snow showers that have been hanging around Western Washington this week. Best to get out and enjoy it if you can, says knkx weather expert Cliff Mass. On Sunday, the threat of snow showers returns, although temperatures will stay warm enough to keep much of the white stuff from sticking. Get Outdoors On Saturday "The best day is going to be Saturday, no doubt about it," said Mass, explaining that a small ridge of high pressure is set to build over the region that day, bringing pleasant conditions with it. "Temperatures will climb into the mid-40s. You'll see a little bit of sun. It'll be a dry day. Everybody's going to be happy on Saturday," he said. Tricky Forecast Sunday On Sunday, Mass says the weather gets "more interesting." He says late Saturday and into Sunday morning, an upper-level trough of low pressure starts bearing down, pushing temperatures low enough to freeze some of the precipitation. "We're going to be right

A Mild And Only Partly Rainy Weekend Ahead As Northwest's Wet Weather Heads For California

The plume of moisture that was aimed at Western Washington earlier this week, bringing huge amounts of rain to the Northwest, is now over California. That means a relatively mild President's Day here, while the Golden State is getting doused. "All the weather's going to California," said knkx weather expert Cliff Mass.

Wind And Rain, But The Sun Will Return To Western Washington

It's a cloudy, rainy Friday with lots of wind expected. But the weather system should clear by the start of the week and bring warmer temperatures and sunshine. "Some places will get winds gusting to 30 to 40 miles per hour, maybe even a few higher gusts," knkx weather expert Cliff Mass said. "It's the breeziest it's been for a while. So keep that in mind if you're around trees or you're worried about your power going out." Mass says Saturday will be a transition day with temperatures getting into the mid 40s and it'll be partly cloudy. "Sunday, the ridge builds up even more and the temperatures will be in the mid- to upper 40s. I think there will be some sun," said Mass. "A really decent day, the nicest day we've had." By Monday, Mass says temperatures will reach into the 50s and it'll feel like spring. And we might consider getting used to those milder days based on a new study by the National Oceanic and Atmospheric Administration. "It took a look at a global-climate model

As Wet Weather Returns To The Pacific Northwest, Is There Big Snow On The Way?

A burst of snow hit the Puget Sound region Thursday night, mixing with rain overnight in areas from Olympia to Bothell to Bellingham. An even bigger snow event could hit the region on Monday, but knkx weather expert Cliff Mass says it's too soon to say whether that will in fact take place. Mass says the air above the region has been cold enough for snow. So when a band of precipitation came up from the south Thursday night, it quickly morphed into the white stuff of winter. "We had a burst of snow that lasted in many places only 15 minutes, but laid down about a half an inch of snow, " Mass said. "So it was all white outside my house, I was pretty excited." But he says temperatures on Friday will be warming up, as a much stronger area of low pressure approaches from the southwest, pushing much warmer air over the region. Mass says some areas around the Sound will keep seeing snow, because of the barrier created by the Olympic Mountains. That means more snow in Bellingham, for example,

Back To Northwest Normal: Showery And Mild Around Puget Sound This Weekend

Relatively mild temperatures and typical damp, showery weather will continue this weekend, providing more relief from the cold spell that lasted through last weekend. And next week will be drier while remaining warm, says knkx weather expert Cliff Mass. "We're talking about normal weather," said Mass, predicting temperatures in the mid- to upper 40s and showery skies from Friday through Sunday. "Typical for this time of the year," he said. Scattered Rain Showers This Weekend Mass says a series of weather systems will be rotating through this weekend. "We have this deep low-pressure center right off the coast. And pulses of moisture will be just circulating around," he said. He says Friday morning's dry skies will be disrupted by a band of showers coming in later in the day. "Another one should come through later in the afternoon on Saturday and another one on Sunday," Mass said, but "after that, things really dry out." Dry Next Week He says a ridge of higher pressure will develop from

Cold Blue Skies Again This Weekend, But Rain Returning To Western Washington On Monday

Clear skies and cold temps have been dominating the weather in Washington lately, and that pattern is expected to continue for the next couple of days. "They go together; that's the bargain, the meteorological deal," says knkx weather expert Cliff Mass. "These really cold days and cold nights tend to be clear," he says of the Northwest winter. The lack of clouds let most of the warmth created by the sun radiate out to space, especially at night. Around the Puget Sound region that's been allowing the temps that come with the blue skies to dip all the way in the teens in some places. Jet Stream Aimed At California Mass says a key factor in our dry weather – as well as all the rain and snow that have been making headlines in Oregon and California this week — is a shift in the location of the atmospheric river off the West Coast, which funnels in moisture from Hawaii. "Essentially the jet stream, which is typically over us this time of year, has moved south," Mass explains. "And on the

Northwest Dry Spell Coming To An End With Warmer Temps And Possible Snow On Saturday

The cold, dry air that's been pouring into the Northwest and keeping temps well below freezing is coming to an end this weekend. But before the Arctic air completes its exit and things warm up all the way, there's a possibility of snow in many areas, says knkx weather expert Cliff Mass. "We have to get through a bit of cold for the next day or two," said Mass, a professor of atmospheric sciences at the University of Washington. Very Cold Friday Morning He says Friday dawned with extremely low temperatures, especially in the eastern suburbs of Seattle, where some places saw the mercury dipping as low as the mid-teens. "So this is unusually cold air that's been over us. And that's going to hold in for at least another day," Mass said. He says Friday will bring one last sunny day to the region, with cool, dry air. But he says temperatures will probably reach the upper 30s. "So a little bit warmer; the air's been warming up a bit aloft." Transition Late Saturday Saturday will start

Brace For Possible Snow On New Year's Eve, Then A Major Cold Wave In Washington

With partly sunny skies and temperatures expected to get into the low 40s on Friday in western Washington, knkx weather expert Cliff Mass says enjoy it while you can. "Wow – that's going to seem warm in a few days," he said of Friday's temps. A major and sustained cold spell is expected to start over the weekend, with a good chance of snow showers in many parts of the region on New Year's Eve.

Slight Chance Of True White Christmas; Watch Out For Slippery Travel Conditions

A white Christmas is a rarity in the greater Seattle area, but it's not out of the question this year. A mix of snow and rain is expected in most places around the Puget Sound region. That could make for some treacherous driving conditions, says Ted Buehner with the Seattle office of the National Weather Service. Snow Possible Friday Buehner says a Pacific weather system is easing inland on Friday, bringing rain to the lowlands and snow up in the mountains. The some cooler air behind it will nudge snow levels below 1,000 feet Friday night and into early Saturday. "So any lingering precipitation could fall as snow," he said. "Most of it will fall in the Cascades and the foothills, but some lowland areas may get some flurries or light snow with light accumulation." Highs on Friday will be around 40 degrees, which is about 5 degrees below average for this time of year. Lows will drop close to freezing. Clearer, Colder Saturday On Christmas Eve, highs will be in the 35-40 degree range. Any

Cold Snap Ending With Possible Lowland Snow On Sunday, But It Won't Last

With high temperatures predicted to remain below freezing in many places around the Puget Sound region on Friday, this weekend is starting with some of the coldest weather people here have seen in quite a while, says knkx weather expert Cliff Mass. "This is the coldest air that we've had over our region probably in the last three years," said Mass, who is a professor of atmospheric sciences at the University of Washington. He expects places near the water will get into the low 30s, just above freezing, but some places away from the water or near mountain gaps will stay much colder, especially on Friday. "Today's the coldest day and it's going to be a sunny day," Mass said. "There'll be plenty of sun and that'll make it seem a lot better." Cloudier Saturday He says expect similar weather on Saturday morning. "Maybe slightly warmer, but not much, so, back in the low 20s, some teens in Western Washington, colder up by Bellingham," Mass said. Then clouds will start rolling in later in the
