Fall has arrived, and with it, a slight chance of rain in the Puget Sound region.
Cool marine air from a weather system off the coast blew into the Seattle area Thursday, gathering strength, scrubbing out smoke that blanketed the region this week and possibly bringing rain Friday, according to the National Weather Service in Seattle.
It won’t be much precipitation, according to meteorologist Kayla Mazurkiewicz, but it could dampen lingering fire danger from what turned out to be the driest Seattle summer on record.
Seattle recorded just a half-inch of rain over the 93 days of summer, the weather service said.
Thursday marked the start of astronomical fall, and once we get past Friday, we could be in for a few days of mild early fall weather with mostly sunny skies and highs in the mid-70s, Mazurkiewicz said.
Enjoy it if you can. On Monday, the sun will set around 7 p.m. and after that we’ll begin losing daylight fast.
The amount of daylight and twilight Washington gets doesn’t increase or decrease at a steady pace from one day to the next, either. Rather, it changes slowly near the solstices in December and June and quickly near the equinoxes in March and September.
At our latitude of 47.6 degrees, Seattle feels the extremes of the solstices more than nearly any other city in the contiguous 48, with 16 hours of daylight and two hours of nautical twilight on our longest day and only eight hours of light on Dec. 21.
“In California, and other places, where the days and nights don’t fluctuate so much, it’s not that big of a deal,” Justin Shaw of the Seattle Weather Blog has explained, “but here we are descending down a mountain and picking up speed as we go.”
