I've done Palm Springs 3 times... I've never had a wind problem. One year it was really hot, another freezin' cold and another cold in the morning and hot by afternoon but no wind. Guess I was lucky.
I'm still thinking about driving out that morning and maybe doing the 50... I have so many friends doing the ride might be fun to tag along. I've never done the 50 always the century. I hear the 50 course is nice...
