We haven't had snow conditions in early November in many years. I agree that Yosemite in winter is magical. Winter, however, means January-February. Maybe as early as Christmas. I go up in early November for fall photographs. The image below was taken on 11/15 a couple of years ago.

In November, the waterfalls will not be in ice and snow, they will be dry, except for the largest which may or may not have flow.

The comment about elevation is well taken which is why I mentioned it. That could be a problem.
