Rain has turned to snow at my house in Mariposa, elevation 2700 feet. We already have an inch on the ground, and the radar shows more on the way. I just talked with Gabe at The Ansel Adams Gallery and he said they’ve received about four or five inches so far in Yosemite Valley (elevation 4000 feet). This is the first snow of the season—always a welcome event! Wherever you live you can see this fresh snow on the Yosemite web cams.
The National Weather Service predicts 7 to 11 inches of snow in Yosemite Valley today, with the storm ending late this afternoon or this evening. For photography, that makes the timing tricky. If the storm breaks up before sunset there could be spectacular light and clouds late in the day. If it waits until after sunset - which seems more likely - and clears overnight, there will be fresh snow in the morning, but probably no mist, as cold temperatures will inhibit mist formation. It will still be beautiful though.
I photographed this manzanita outside my office in January 2008. If the snow keeps falling it will look like this again soon!
This storm is so cold that it may snow in the Central Valley. Is it snowing where you are?
