Cam, viewing the webcam daily sets, Mt Whitney has been virtually cloudless the past several days, so pretty balmy weather, but likely chilly. I think you are going to have a really windy experience at Horseshoe Meadows tomorrow, so be prepared with warm clothing.
With that chance of snow, and if you can adjust your schedule, you might inquire when you pick up your permit about trading your permit for Friday. It looks like Friday will be calm and clear.
That snow prediction is for a light dusting, so you you are prepared, it shouldn't affect the trail. We would sure like to hear how it turns out!
