Thanks to Laura Lilly for catching the Yosemite Conservancy Org's Ahwahnee Meadow webcam image,
which of course changes through the day daily.

30 minutes later, the view of Half Dome was obliterated by the snow/fog...
Weather: 32 degrees at the time (aka freezing)

And a bit later, after the invisibility of Half Dome, a ***HUGE CHANGE again*** ...Just GORgeous.

We had read that Saturday would bring a somewhat severe storm and were glad about our timing.
Would not have been very comfortable lying down on that meadow at that temperature.  :-)
