I haven't been up there this year but I've climbed that route in different seasons and with the quantity of snow this year I would think there is still snow on that route. There are two sections of 4th class slab that tend to hold snow and there's still a lot of snow in the mountains especially at that elevation. I've climbed that route when it was snowy and the parts that hold snow tend to be easier sections. I would think the traverse face parts are dry but you should be prepared to do some snow climbing. Only 1 way to find out though! If you go up there with a plan b and C you can clearly see the entire room from below and make a decision.
I think parties have been climbing on the east-buttress & east face since early-may, you can check out @SierraMountainGuides on IG, they usually post some fairly current updates/images.
Don't think there is any snow left on either of those routes now, but microspikes or crampons, & probably an axe would be advisable still if descending the MR.
Here is a frame I took when I was driving through Lone Pine on 7/15. E. Face seems bone dry.
