Weather with Cliff Mass

Puget Sound Energy

Winds that toppled trees and caused about 150,000 power outages around the Puget Sound region have subsided, but they made for some exciting weather Thursday night, says KPLU weather expert Cliff Mass.

Replace your wool hat and gloves with your rain gear. We’re back to warm and wet weather, says KPLU weather expert Cliff Mass.

The rain will settle in Friday and temperatures will rise into the 50s, says Mass, setting the stage for the rest of the weekend.

The week before Thanksgiving is normally the wettest, stormiest part of the year in the Pacific Northwest. And true to form, the rains and wet clouds are back, says KPLU weather expert Cliff Mass.

“If you look at the records going back decades, this is the week: ground zero for storms and wetness here in the Northwest. And it may not disappoint,” Mass said.

Keep your hats and scarves handy. The clear skies and cold temperatures we’ve been experiencing will continue through the middle of next week, says KPLU weather expert Cliff Mass.

Sick of the howling winds that swept through Thursday? KPLU weather expert Cliff Mass has good news: “We’re not going to see that the rest of the weekend, and early next week, just the opposite.”

This weekend will start off wet and cloudy, but the rain will give way to milder conditions, says KPLU weather expert Cliff Mass.

Mass says things will steadily improve over the weekend, with each day a bit better than the last.

A warmer planet will certainly cause more intense rains in the Northwest and we should start getting ready for that now, says KPLU weather expert Cliff Mass.

Fall is in the air, and you’ll want to keep a raincoat handy, says KPLU weather expert Cliff Mass.

Mass says we can expect a big transition to deep autumnal clouds and rain early next week. But the weekend forecast is not as wet as predicted a few days ago, and Sunday should bring a break from the rain.

The weekend forecast is more complex than usual, thanks to something called a dirty ridge moving in, says KPLU weather expert Cliff Mass.

Sunny Friday Before Dirty Ridge Moves In

Friday will be a "very, very nice day" with sun and temperatures reaching the lower 70s, thanks to a ridge of high pressure in the skies above.

“A perfect fall day – well above normal," Mass said.

But he says on Saturday, something called a dirty ridge is expected to move in, bringing dueling weather regimes with it. A dirty ridge is an area of high pressure that’s not strong enough to push out all the clouds and rain. As a result, it will allow two weather regimes to settle in over the region.

It may be tempting to attribute current weather trends like the record warmth and early rains on climate change caused by humans. 

But KPLU weather expert Cliff Mass says a newly-published paper should give us pause. It shows that the global warming of approximately 1 degree Celsius on the U.S. West Coast since 1900 appears more likely to be the result of natural variations than of human inputs of greenhouse gases.

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.

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.
