Wussy right back atcha. 106 and 10% humidity. That's kid's stuff. I've been to Vegas several times... 100 degrees plus and you don't even break a sweat in that dry desert air.
Try 95 degrees and 70% humidity and see how long you last!
Harry I grew up and did my entire career in St Louis. We're talking 98 and 90 percent humidity some summers.
I got tired of breathing through a straw and moved here. Trouble is week before last we had, for us, high humidity (40%) and heat (upper 90's). That created some of the gosh darndest thunder storms I've seen lately.
The desert cannot absorb that much water that fast so we had flooding and roads washed out. Still I wouldn't trade it for the midwest ever again.
