Really. It hardly rains at all in the summer here. Just sun and heat, sun and heat. Everyone has to water their lawns or they all die. I grew up in New England where we had proper storms in the summer, and I WISH we had them here, if only to get a little wx excitement once in a while.

I lived there for 3 years and we got a ton of storms. I'm quite surprised - eastern washington used to get them relatively often during the summer.
Well, eastern Oregon on the eastern slope of the cascades gets quite a few as well, and I got there often enough to experience them :)
