Matt just posted an image on his co-worker's Flickr stream of the weather in Kansas over the next few days, and it's *hot*. But you know, I miss that! Northern California had it's two week "heat wave" about a month ago, and it's been a lot cooler ever since. I'm not sure if I need it to be 100F or anything, but I definitely think August should have a few sweltering days in it. Just to really give you a nice memory of Summer that you can take with you throughout the rest of the year.
Oh, I also miss thunderstorms too, but that's a whole other thing. :-)
