Oh, you guys made me spit my coffee out I was laughing so much at the "So does this mean that H**L has frozen over?" over comment. I still remember the post card I had hanging on my fridge during most of the time I lived in AZ:
"Tempe Arizona... Home of the Sun Devils; two miles from H**L" (showing a half dead coyote lying on the ground).
Seriously, I remember many mornings in the 30s as I was going to work. It did usually warm up more than you're describing, but it DOES get cold in the valley. Too bad it gets warm more of the time.

Still no snow here in greater Boston. Heavy rain, temperature hovering at 32.9 so no ice.
