Yeah, Tom, people like to scream about wind chill but don't think about that convection oven effect out here. Roofing as a newcomer?! You got a big brass set my friend!! <lmao> Back in the '90s Phoenix rebuilt the area where their "official" temperature station was at the airport...GOOD shade (there is a difference), lots of grass to keep it cool. The official Phoenix temperature dropped to about what Tucson's was...until the Tucson weather people pulled the same stunt. It is a given fact here: if you are at a picnic in July, just gotten your plate of food stacked high, drink and EVERYTHING else in your other hand, and are walking to the nearest shade to sit and eat, you WILL be attacked by a Dust Devil that has at least enough force to bend your plate. PLOP Sandblasted AND still hungry. Jon
