I hope you have a set of crampons, ice axe, gaiters and basic snow skills. There is a fair chance they will be required.
My guess you might need at minimum some type of traction device. There are 10 weeks to your trip...more or less. In that time Mother Nature will either be benevolent or a real mother, that is, it will warm and a lot of winter will melt away or it will be cool and June 30th will look like May 1st most years.
