That's what it's going to be in the Southwest US next week, too. A little bit early in the summer for those extremes, but not unheard of. But up there?!? Where you are?!? Holy misery!
You know the drills for you and the dogs. Lots of clear fluids, pace your physical activities, don't go out in the noon-day sun, Ahhhhhh! GAZEBO! Avec a petit fan, perhaps?
