Those hoping for sunshine will have to wait a little longer.

Cliff Mass, Atmospheric Sciences Professor for the University of Washington, told “The Jason Rantz” Show on KTTH Thursday that this weekend’s weather will be cooler than normal.

“There will be rain,” Mass said. “By Thursday night, the rain will be coming in. There will be kind of a break on Friday, but then more rain is coming in on Saturday. So there’s going to be a lot of showers, nothing super deluxe, heavy. But we have a series of weak disturbances coming through. So this is going to be a cooler-than-normal period and a wetter-than-normal period through the weekend.”

Mass: ‘No indicator of climate change’

Mass added that temperatures vary every spring and that this weather isn’t out of the ordinary.

“There’s a lot of variability in the weather,” he explained. “Each spring is different than the other springs, so there’s no deep message there about what we’ve seen. There’s no indicator of climate change or something else that could be going on.”

Looking at the amount of rain overall, Mass noted the reservoirs are in good shape.

“Most of the reservoirs, like Seattle, are nice and full,” he said. “On the east side, it’s about, it’s about 75% of normal for the Yakima Basin. So it’s a little bit below normal, but there’s no crisis there. And the fact that we’ve been mild, haven’t gotten hot, means we’re not burning through the water very quickly. So all in all, we’re probably in pretty decent shape for the summer.”
