You might find my reply to Avi helpful. We actually started out wanting to do the same as you (JMT NOBO) but decided to bail out through Whitney Portal. The west side of Whitney was doable—I think easier than what you might encounter on passes farther north on the JMT. Whatever your trip ends up being, wishing you happy trails!
Super useful. I am tentatively looking at an August 8th start from Kearsarge Pass.....really praying that we are done with snow and ice in a month's time!
I will keep checking. Thanks for sharing your feedback.
