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

Fall came in with a vengeance this week. An early atmospheric river dumped huge amounts of rain into the Northwest over the last few days, but it’s tapering off just in time for the weekend, says KPLU weather expert Cliff Mass.

“It actually looks like a decent weekend,” Mass said.

Don’t put away that sunscreen just yet.

Temperatures are expected to shoot back up into the upper 70s and even 80s for the last weekend of summer, topping off what will likely go down as the warmest summer in Seattle history.

We may get a rare treat this weekend. There’s a real chance we might catch the Northern Light in western Washington, says KPLU weather expert Cliff Mass.

“Perfect viewing conditions,” Mass said. “The skies are not only clear but they’re dry. The viewing is good; the big question is whether we will actually see them.”

The record-breaking summer isn’t giving way to fall just yet. Another gloriously sunny Northwest weekend is in store, says KPLU weather expert Cliff Mass.

“We will have a really beautiful weekend — no precipitation, clear skies and warming temperatures,” Mass said.

This summer, we’ve already beat the record for the hottest July and August ever in the Seattle area. And this weekend, we can expect to build on that trend with clear skies and warming temperatures pushing toward what will likely be the hottest full summer season on record, says KPLU weather expert Cliff Mass. 

“We’ve been having the best summer on record here in Washington state, and it’s not going away,” Mass said.

It won't be long now. 

Fall is just around the corner, says KPLU weather expert Cliff Mass, and that means the holiday weekend won't be all sun. 

"We'll see a different weekend than we've been used to in the past," he said. "Temperatures are going to drop way back. No more 80s."

Keep the sunscreen and swim trunks handy. The clouds are melting away and the forecast predicts another hotter-than-normal weekend with temperatures above the mid-70s that are typical for this time of year.

KPLU weather expert Cliff Mass says we are experiencing one of the hottest summers on record and could soon chart the hottest one in Northwest history.

A week of rain has turned what was a dry summer into a normal one, says KPLU weather expert Cliff Mass.

But don’t let the clouds and drizzle get you down. Mass says the forecast will progressively warmer and sunnier over the weekend.

Go ahead and gloat. We’ve got one of those hot, sunny August western Washington weekends ahead that make it worth living here despite the long, dark winters.

Low clouds will melt away, says KPLU weather expert Cliff Mass, as temperatures steadily rise over the weekend, hitting 90 maybe even as early as Sunday and certainly by Monday.  

“A warming period is going to happen,” said Mass. “And that’s because a trough that brought us cooler temperatures this week is moving off and a pretty high-amplitude ridge is building in its place.”

There will be plenty of sunshine for Seafair weekend, says KPLU weather expert Cliff Mass, but dry conditions and a chance of lightning could mean trouble for firefighters.

If you love sunshine, Friday’s the day to get out and enjoy it.

The cooling trend we’ve been experiencing will continue this weekend and even bring some rain with it, says KPLU weather expert Cliff Mass.

Make sure you’ve refilled the ice trays. KPLU weather expert Cliff Mass says it’s going to get hot in the days ahead.

Sunny skies on the Fourth of July are not something to take for granted in Seattle. But revelers can count their blessings this year, as the clouds are expected to burn off and give way to a decent day for picnics and fireworks displays, says KPLU weather expert Cliff Mass.

“Much better than some other Fourth of Julys,” Mass said.

Keep your rain gear handy if you’re headed outside this weekend. KPLU weather expert Cliff Mass says we’re starting to pay for the drier-than-usual June we’ve had this year.

But Mass says sunny days are around the corner; things will improve by the Fourth of July weekend.

The nude cyclists at Seattle’s Fremont parade can look forward to comfortable summer temperatures on Saturday afternoon. And it might even be a bit too hot for runners at the Rock 'n' Roll Marathon, says KPLU weather expert Cliff Mass.

A weak front has passed through, says Mass, and the clouds and sprinkles are expected to subside in time for the summer solstice Saturday.
