The National Weather Service has issued a Winter Storm Warning for Yosemite from 4 p.m. Friday to 7 a.m. Saturday. The snow level is projected to begin at around 5000 feet Friday afternoon, but drop to 4000 feet—the elevation of Yosemite Valley—Friday night. Exact snow levels are difficult to forecast, so a slight fluctuation could mean rain instead of snow, but it seems likely that the Valley will get at least a dusting. Forecasters are predicting two to four inches of snow at 4000 feet, four to eight inches above 5000 feet.
For photographers, the big question is when the storm will clear. It looks like it might clear sometime during Friday night, meaning Saturday morning could be beautiful. Or not. It’s always unpredictable! But whenever it clears there will probably be great conditions for photography.
