Good morning and happy Monday.
Stay cool, we have a couple days of hot weather ahead. KOMO Weather Warn Days have been enacted for today and tomorrow as the mid-90s creep into the South Sound. Then a cool front will drop temperatures 15+ degrees from Tuesday – Wednesday. A stronger system brings a good chance for fall-like rains by Friday.
Out the door this morning, it was quite warm in Seattle. Our low of 69 tentatively makes today our ‘warmest morning’ yet this year, although many areas in the South Sound dipped into the 50s.
Aside from some pockets of low marine clouds/fog over the Strait and Pacific waters, we’ll have abundant sunshine today and a rapid warmup. Most areas from Shoreline to JBLM will be in the 80s by noon. 3-6 pm, the warmest part of the day for many, we’ll approach 90 for Lakewood and Puyallup. Olympia through Chehalis will heat up to 93-95 degrees while Wenatchee and Yakima approach 100. Forks and Aberdeen even approach 90, meanwhile right along the cool ocean waters of Moclips and Westport, mid-70s.
Tomorrow’s a repeat, and a couple degrees hotter. The marine clouds will be just a little thicker near the Ocean Beaches, a sign that it intends to push inland soon. It will, Tuesday night.
That flips our natural air conditioning on for Wednesday, complete with morning clouds and foggy/misty spots. Afternoon clearing will be temporary as the marine push will be even stronger on Thursday morning. Wednesday and Thursday afternoons fall into the low-mid 70s.
But Friday, bigger changes evolve. We have the chance of widespread soaking rains developing, which would come with clouds and even cooler 60s most of the day. At this point the whole day has the potential to be wet…and fairly gusty. Right now, lowland rains may top an inch, but we’ll have a better idea of these numbers as we get closer.
Have a great week!
