Weekend forecast: Warm April showers to melt snowpack

Those showers that blew in on Thursday will keep blowing our way through Sunday, says KPLU weather expert Cliff Mass, a professor of Atmospheric Sciences at the University of Washington.

“And that’s a big change,” he says. “The first real rain that we’ve had in a long time happened last night (Thursday), where a lot of people got about a half an inch. But it’s not the end."

And, because it's been warmer rain, the snowpack in the mountain passes is melting quickly, he says, losing about 20 inches.

Mass says another front will arrive late Friday.

“And this will be pretty wet one. So showers will pick up by dinnertime. It will be raining through the night,” he says, adding winds will pick up in the Northwest part of the state and along the coast.

Come Saturday, there will be more showers, both in the mountains and in the lowlands.

“There will be breaks,” says Mass. “And then on Sunday, I expect a lot more (sun breaks). So Sunday will be a much better day.”

Mass says the mountains will see fresh snow again late Sunday when temperatures are expected to drop.
