Hmmm Interesting. 
I also have a overnight permit starting August 8(till August 10).
This is my third straight year to summit the Whitney.
First year was Day hike and last year was overnight hike and camped out at
Trail Camp. My this year plan is about same as last year. (starting Whitney Portal around 9 and camping at Trail Camp on Aug. 8.)
I just checked the weather and it forecasts clear Monday night thru Friday. about 50'F at Trail Camp
At dawn, plan to hit the 99 switchback and be at Summit before 10 am and come back down all the way to Portal.Back up plan (if rain/t storm): Aug 10 Attempt. One more night in Mountain.I have done Grand Canyon Rim to Rim hiking and almost hike every week past 5 years.We may see each other on the trail.
