Cooler temps, clouds and wind gusts ushered out the record warmth Seattle area residents experienced in May, which also tied a record for lack of rain. All that changed on Friday as marine air surged in and cooled things off.
“So a little bit breezy this morning,” said KNKX weather expert Cliff Mass on Friday.
He says the first day of the weekend will start with partly cloudy skies and a little bit of sunshine in the afternoon and high temps in the upper 60s.
Mass, who teaches atmospheric sciences at the University of Washington, says people here should expect Saturday to be the best day of the weekend.
“We’ll have some clouds, maybe a few sprinkles in the north and over the Cascades, but nothing serious,” he said.
Temperatures probably will get up to the lower 70s in the mid-sound, so a pretty decent day. But he says on Sunday things will start going downhill.
“An upper-level trough will be approaching and it’ll probably be dry in the morning, but then clouds will thicken. And I think there’s a very good chance of precipitation later in the day on Sunday,” Mass said, adding that he expects about a tenth to two tenths of an inch of the wet stuff.
“So this is going to be the heaviest rain we’ve had yet for the last month.”
Mass says Monday will still be cloudy. Then it looks like it will improve next week.
“Pretty typical weather, but I think we will see some real rain later on Sunday,” he said.
As for the rest of the month, Mass says he isn’t expecting much more rain, just the mild and hazy weather that he often refers to as "June Gloom."
“We’ll have plenty of clouds and maybe even a few sprinkles,” Mass said.
