Sarah speaks no lie, Bob!!!
Hands down, probably the best month to visit, especially with your itineary.
In Colorado, at least in my experience, a good,
light, waterproof shell will go a long way towards your comfort level up high.
I have an 8-year old Marmot Precip shell I still use with a single, long-sleeve shirt underneath or regular cotton t-shirt if it's warm. Works wonderfully.
I used the same jacket treking up the Kahiltna a few years back even.
Bit of advice on Vestal: the class-3 backside 'regular' route is
hard to follow. It's poorly cairned as that entire south side is loose, a bit on the rotten side and crumbly.
Completely opposite from the North Face. Just take care and mark your path or note certain features
(what I do).
Hiking up into Vestal Basin is a bit of a bear too. Lots of deadfall.
You're gonna fall in love with the San Juan's, buddy!
