I lived in Las Vegas from 2003-2005, and it snowed. On one occasion, the phones were ringing off the hook because it actually stuck, and the kids were able to make snowmen. The strip always felt a good 5 degrees warmer than where we lived in Summerlin. I actually wore my winter coat from the East Coast in the winter, but, I could still hike in the warmth of the day. In the summer, we were able to see an egg bubble up and semi-fry on a piece of black asphalt. I live on the East Coast and the biggest difference to me was the lack of humidity.
