I will let others comment on what ice and snow may remain in two weeks and what equipment would be needed to deal with them. I don't do winter hiking.

Mountains can have any kind of weather any time of the year without much warning. Bring layers and a waterproof, windproof outer shell.


I can second that. I did Whitney last year in August and the thunderstorms would roll in around noon almost like clock-work the 3 days we were there. It is NOT fun to get caught in a hail-storm close to the summit. We ended up start the hike on summit day at 1:30 am. Summited by 11am and just about missed the thunderstorm at the top. Still got hit by crazy hail on the switchbacks on the way down.
