It's warm today

We've had a series of lovely sunny days lately, and this morning was the first time this year that I've walked to work without a warmth-layer of clothing on. It was 62 F when the radio woke me at 6am. By the time I got to my desk after my half hour walk, I was sweating. So today it seems like summer, and I ain't complaining. I am skeptical, however. The rule of thumb in Seattle is that the rain stops on July 5th (i.e., right after it has rained on your Fourth of July barbecue.) This can't last ... can it?
