It seems that it was a hotter, drier summer in the southwest and up though the Texas panhandle and therabouts, while the Pacific Northwest had a cold spring and a cool-to-average summer, compared to the record temps we have had the last couple of summers. I wonder how it averages out globally.
It's kind of fun for me to see the reports for high temps this summer from around north America. We were in so many of those places, and I recorded the daily high and general conditions on each day. Either from my RVWS if we were on the road, or the nearest WU station if we were stopped. Joseph mentioned SD. We spent a couple of days there in late July, and it was comfy for us. Whatever the humidity, it is drier than the PNW, and MUCH drier (and cooler) than once we reached Ontario and the entire east coast, until we got back to the Albuquerque area. Then it was just hotter than heck (but a dry heat) until we got home in mid-August.
