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

Snow in the Cascade mountains is the deepest in America these days, says KPLU weather expert Cliff Mass, and the weather pattern is likely to stay the same well into next week.

And, as for the dusting of snow, ice and sleet around portions of the Puget Sound lowlands, that should all melt off by this afternoon, says Mass, a professor of Atmospheric Sciences at the University of Washington.

The next storm front is headed our way for Saturday morning, says KPLU weather expert Cliff Mass, a professor of Atmospheric Sciences at the University of Washington. And Sunday afternoon could get a warmer, wetter blast.

But, what's really intriguing him is the Monday forecast.

"The computer models don't agree," says Mass. Some bring the storm system's center north of Puget Sound, other models send the storm south.

"This is fairly strong ... so it could bring winds, even winds here to Seattle," on Monday, he says.

The weather pattern has shifted, and that means less rain, more chills, says Atmospheric Scientist Cliff Mass, of the University of Washington.

The pattern is giddy news for mountain ski areas, all of which should be open with light, fluffy snow this weekend, he says.

Don't worry, though, the snow should stay away from the Puget Sound lowlands, although the higher foothills may get a dusting tonight or Saturday morning.

At least three or four more days of rainstorms are headed to the northwest. They'll cycle through approximately every 18 hours, says KPLU weather expert Cliff Mass, a professor of Atmospheric Sciences at the University of Washington.

Those late November storms are a tradition in the northwest. But after some Friday rain, the trend is drying out, says KPLU weather expert Cliff Mass, a professor of Atmospheric Science at the University of Washington.

In this week's weather talk, Mass explains why late November gets more inches of rain than any other period of the year. Hint: It has to do with the jet-stream, heading at us from Asia. After November, that "atmospheric hose" is pointed farther south in Oregon and northernmost California.

We're entering the wettest two-week period of the year, says Cliff Mass, KPLU weather expert and professor of Atmospheric Sciences at the University of Washington. And this year should not disappoint.

The rain we've been hearing about this weekend will really just be light showers, says Mass, unless you're on the coast or in northwest Washington, where you'll get blasted with high winds.

That's right, KPLU weather expert Cliff Mass says those who live in "these low spots, places where the wind doesn't get into, these hollows" could see temperatures in the 20s early Saturday morning.

The heavy rain we saw earlier this week was part of an "atmospheric river" carrying moisture across the Pacific, but it's gone now, and off-and-on showers will be the norm for the next few days, says Cliff Mass, KPLU's weather expert and a professor of Atmospheric Sciences at the University of Washington.

Northwest dampness comes as the rest of the country is drying out, and Mass says that's good news for President Obama. He cites research that shows Republicans do better when it's rainy on Election Day, and Democrats do better when it's dry.

Lots of rain in the forecast, but a surprising break is coming on Sunday - at least if you're north of the Tacoma area.

The pattern has shifted, and rain is here to stay, says KPLU weather expert Cliff Mass, a professor of Atmospheric Sciences at the University of Washington.

By this evening, we'll be in an "occasional showers" mode, which means you might find dry spells this weekend to rake leaves and be outside.

Want to avoid getting caught in a shower? Mass suggests using the local weather radar, to check the latest status.

Expect light, misty rain for much of today, says KPLU weather expert Cliff Mass, professor of Atmospheric Sciences at the University of Washington. And a much stronger front is approaching on Saturday night -- bringing heavy showers on Sunday.

Don't credit global warming. And don't call it karma. Sometimes, weather patterns just lock in place, says KPLU weather expert Cliff Mass.

Today, the pattern is perfection. Sunny, clear skies, with temperatures in the upper 60s, occasionally breaking 70, says Mass, a professor of Atmospheric Sciences at the University of Washington. And seven days in a row of that, stretching through next Thursday. It could change at the end of next week, but maybe not, he says.

Yes, this morning's brief showers showed that in fact our fabulous summer is at an end (but there will be more sunny days to come), says KPLU's weather expert Cliff Mass.

Mass added that forecasters were blindsided by this morning's rain across the region, but they are back on track with predictions of a front moving in this afternoon. That front too will bring some rain, but the clouds will burn off probably by Saturday evening and Sunday will be sunny.

Greg Johnson, a Puget Sound weather aficionado, was recently called out by KPLU’s own weather expert Cliff Mass for a unique video that shows the development of superior mirages during the day. And, with our string of sunny days, there has been plenty of opportunity to see the mirages this summer.

He seems like your ordinary scientist, but KPLU weather expert and University of Washington professor of Atmospheric Sciences Cliff Mass has been moonlighting. He can be found in courtrooms, as a favorite expert when the weather may determine guilt or innocence.
