After A 'Normal' Week, Things Will Heat Up Again

Apr 29, 2016

"The atmosphere has been very kind to us," KPLU weather expert Cliff Mass said. "The weekend is going to get progressively sunnier and warmer as we go on."

Friday will be cloudy with some modest rain, but as we get later in the day the front will move out and the rain will come to an end. We'll see 60s and 70s over the weekend for our highs and Mass says by Monday we could see temperatures into the 80s. But it won't be as warm as our record-breaking heat from earlier this month. Mass says it's been a "normal" week.

Why did we have such a long stretch of fog? Blame the inversion, says KPLU weather expert Cliff Mass.

Foggy days in the fall aren’t uncommon in the Northwest, but the recent long stretch—the so-called “Fogtober” and “Fogmageddon” that Mass said will finally leave us Sunday—is quite rare.

Fogmageddon will end on Sunday, “pretty much guaranteed,” says KPLU weather expert Cliff Mass.

The very dense fog hanging around the region this morning bodes well for a long sunny day ahead, and the week will continue with that pattern, says KPLU weather expert Cliff Mass.

“As I mentioned before, that’s a tremendously good sign,” said Mass, who teaches Atmospheric Sciences at the University of Washington. He says the densest fog usually means the sunniest afternoons.

“The clouds, the cold air, that low foggy layer is actually very shallow today and I expect it to burn out much quicker than it has in the past,” he said, predicting that it should be completely sunny outside by 11 this morning, with temperatures going up to around 60.

The clouds and light rain that have been darkening skies in southern King County should give way to dry weather and partly cloudy skies later today. And that’s just the first glimmer of nice fall weather in a week that promises to bring lots of mid-October sunshine.

That’s according to KPLU weather expert Cliff Mass, a professor of atmospheric sciences at the University of Washington.

“By this afternoon it’ll be partly cloudy,” Mass said, and “completely dry in all of western Washington.”

In some places, such as eastern Washington farms, they actually use giant fans to disrupt the inversion that causes stagnant air (which is what we've been experiencing for a week, and can leave frost on fruit trees).

But, KPLU weather expert and UW professor Cliff Mass says those fans won't work in western Washington, because the natural forces creating the inversion are too strong. Instead, he suggests taking a hike.
