This is Late August. Until the next snow storm, there should be no snow anywhere on the main trail, except maybe for a little patch just before the summit. And that one always has a deep groove through it where the thousands of hikers have walked all summer.
As for the Mountaineer's Route, no snow except the center of the main chute below the notch. But that is usually avoided by staying on the rocks on the left side as you go up.
