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.
