El Niño

Go ahead and gloat. We’ve got one of those hot, sunny August western Washington weekends ahead that make it worth living here despite the long, dark winters.

Low clouds will melt away, says KPLU weather expert Cliff Mass, as temperatures steadily rise over the weekend, hitting 90 maybe even as early as Sunday and certainly by Monday.  

“A warming period is going to happen,” said Mass. “And that’s because a trough that brought us cooler temperatures this week is moving off and a pretty high-amplitude ridge is building in its place.”

This summer in the Pacific Northwest will be warmer than average, according to the National Weather Service.

The supercomputers at the Weather Service's Climate Prediction Center have crunched long-term trends to produce an outlook for June, July and August. For most of the Northwest, the forecast gives a strong probability of above-normal temperatures.
