It has been a hot and sometimes sweaty 4 days! Check out the PDX numbers:
At McMinnville, Troutdale, and pretty much all of the Willamette Valley it has been 4 days at/above 90. Whew…time for a cooldown. Sure enough, we are finally getting drier air/lower dewpoints along with a weak marine push this evening. That should drop the valley temperatures a good 8-10 degrees tomorrow keeping high temperatures below 90.
The bad news is that we have another heat wave on the way later this week. This one is a little different because it’s brought on by a bit more of a “fall pattern”. A cool shot of air drops into Montana; that’s high pressure to our east Thursday and Friday. Then we get easterly wind over the Cascades and through the Gorge. Not a strong wind like mid-fall but enough to push our temperatures way up. Right now it looks to me that we’ll see high temps in the 95-100 degree range both Thursday/Friday.
So much for a “cool” summer (which wasn’t cool anyway); it appears August is going to end up very warm. As of now we’ve seen 8 days at/above 90 in Portland, and we have at least 3-4 more.
