Seattle has had one of the worst Summers in my memory.
Five straight weeks of temperatures 5-15 degrees above normal.
“Normal” is usually in the 70s for this time of year.
We have had a huge high pressure dome just sitting over this region for weeks. It pulls super heated air from the central California valleys straight up into Washington state.
If the high pressure was 100 miles further to the east, it would have pulled 95-100 degree air over the Cascades for days on end.
Instead, the high pressure is mostly over the Pacific, which “cools” it to 85-90 degrees, but with tropical humidity levels.
You can't brush your teeth without breaking into a sweat.
In King County (Seattle), only one third of homes have air conditioning.
I appreciate the feedback. That accounts for the west coast. But North America is pretty big and a heatwave in one region hardly verifies Glowbull Warming of the planet.
