In 2012, it was 94 degrees on a September day in Las Vegas, yet it snowed at Mount Charleston.

The snow fell at 8500 feet, which is 6400 above Vegas (2100 elevation).
6400 feet in elevation is typically a 35 degree temperature difference, so obviously such snow was highly unusual given Vegas being 94.
