It is still very snowy, and will be until mid June. Technical snow climbing right now. For the most current information on the snow pack and conditions you can call the Lost River Ranger District at this number (208) 588-3400.
I've been checking the IDT road cam's quite regularly. My guess is the true "summer" conditions won't happen until July at the earliest. Meaning 3 season gear will get the job done, crampons and ice ax not required.
Click on the cam that is between Challis and Arco.
