Seattle weather: Another warm day before cooldown over the weekend

The ghost of summer is not done haunting Seattle yet.

A visage of summer scared the sweaters off the city Thursday with temperatures climbing scarily close to the 70-degree mark, reaching about 68, said National Weather Service meteorologist Dana Felton. But Friday should do us worse.

Don’t let patchy fog belie a sense of fall as the city awakens Friday morning. The wispy veil will draw back by midmorning and give way to partly sunny skies, and we could see temperatures 10 degrees above normal, Felton said.

Normal this time of year is about 60, Felton said, so how does a forecast of highs in the low 70s sound to you? Confusingly sweaty? Understandable.

But an incoming weak weather system will exorcise the near-summer spirit from Seattle come Saturday, returning a more fall-esque chill to the leaf-sprinkled streets.

Temperatures will dive back down to normal with a high of about 62 as the clouds roll back in, Felton said. But the weather system is falling apart on itself, so don’t expect too much accompanying rain.

The system will clear out by Sunday, but a cold mass of air over the city will keep highs around 60, Felton said, and things should remain dry.

If you end up missing the curious resurgent heat of summer by the end of the weekend, Monday will be no relief. Cloud cover hanging over the city will dip us below the average, with highs expected in the mid to upper 50s.
