Seattle weather

Western Washington’s unseasonably high temperatures will be subsiding, but KPLU weather expert Cliff Mass says you may want to keep the shorts and sunglasses handy.

“I’d keep them around,” Mass said, though he added that many people will be needing them less over the weekend. He said Friday will still be very warm and sunny.

“Maybe not quite as warm as yesterday, in some places,” he said, but the air above us is still “warmer than we generally see till the middle of summer.”

A mostly cloudy scenario is in store this weekend, with rain only coming into the picture late Sunday and cooling mostly holding off till then too. So if you like grey skies and mild temps, it’s a great time to get outdoors.

“Today is going to be a perfect day for anything,” says Cliff Mass of Friday’s mix of sun and clouds.

“Temperatures are going to get up into the low 60s in many places away from the water — very nice day, plenty of sun, a few high clouds,” he said, summarizing it as “a spectacular spring day.”

Statistically speaking, it generally is the driest time of year in western Washington. Because of this, late July into early August is the most popular time for outdoor weddings and family reunions in the region.

But showers are in the forecast this weekend. If you were thinking of getting outdoors, you’ll have to travel east over the mountain passes, advises KPLU weather expert Cliff Mass. He says there’s a band of precipitation approaching from the west that will definitely dampen the region, pretty much anywhere west of the Cascades.

Stormy weather is not unusual this time of year. But the wind has blown in an all-time record high December temperature.

The National Weather Service says 66 degrees were charted Wednesday at Sea-Tac Airport. It’s the warmest for any December going back to 1945, when record keeping began. That caught the attention of KPLU weather expert Cliff Mass.

Most of the snow fell overnight while western Washington slept, and "the worst is over," says KPLU weather expert Cliff Mass. The metropolitan area of Seattle saw ¾-inch to 3 inches of snow while areas north of the city saw more.

“But for most people, they’ve seen the bulk of what they’re going to get," said Mass, who teaches atmospheric sciences at the University of Washington.

Drizzly skies are expected to yield to warmer temperatures and some sun this weekend, because of an upper level trough over us and that’s causing upward motion and clouds, says Cliff Mass, KPLU’s weather expert.

Expect progressively warmer weather over the weekend and through Tuesday, says KPLU weather expert Cliff Mass.

Mass, a professor of atmospheric sciences at the University of Washington, says the heat wave hitting the western U.S. is heading our way. He expects highs around 90 on Monday and Tuesday from Seattle to Bellingham, and temperatures in the lower 90s in the south Sound.

Scientists have confirmed what many suspected about this year’s weather. It was the coldest spring on record for Washington and one of the cloudiest.
