Mass: Soak Up The Sun This Weekend Before Ridge Begins To Shift

Start planning your weekend. The forecast looks sunny, dry and warm, says KPLU weather expert Cliff Mass.

“Temperatures in the lowlands will reach lower 50s in some places. And some spots along the coast might even see lower 60s,” said Mass, who teaches atmospheric sciences at the University of Washington.

The sun will stick around all weekend, Mass said, adding we might see some morning clouds but not any precipitation. 

“So expect clouds in the morning, breaking out in the afternoon and temperatures getting up into the upper 40s for most of the lowlands for Saturday and Sunday,” Mass said.

Monday will start with a sunny morning before things start to change.

Models show the ridge will likely begin shifting next week, which means we might see some rain return, but “nothing serious at all,” said Mass.

“We’re going to start getting some modest weather systems, some weak fronts. They’ll bring some clouds, maybe some light rain — probably some rain as we get into Tuesday, Wednesday, Thursday,” he said.
