Most probable are amazingly blue skies, with the possibility of
late-day clouds building to a point that may or may not produce a
shower, maybe even a bit of hail. Mt. Whitney often generates its own
turbulent weather, so best to get up there early in the day.

Night-time temps are likely to be around the freezing point.

Last year produced a lot of unusual weather around that time that
persisted for two or three weeks.  Rain/snow and below average temps.
Good places to check the forecast when you get up there are
