Hey, I summited yesterday (10/7). Until reading some posts today, I hadn't realized incredibly lucky my group was in being able to summit, with the snow early last week and rapidly changing conditions. We went up without crampons with the mindset that we could always turn around.
My group (of 2 others) began hiking at 4am (from portal), reached the switchbacks around 8-9, trail crest at 10, and summited at noon. We spent an hour recovering at the top (left at 1) and reached trail crest at 2:15. It was snowing heavily on the camp side of the crest, and we hiked out through snow all the way down to Lone Pine Lake (around 5:15). On the way up, the switchbacks were not bad (couldn't have used crampons - not enough snow/ice), except for one patch of ice by the cables. On the way down, the fresh snow helped our traction. We made it up and down with poles only, and others made it without poles. We did not have crampons.
Since we didn't stick around in the snow to be able to give a condition report, I can't tell you how the switchbacks will be on Monday. However, there is lots of fresh snow from yesterday afternoon, and I can only imagine it freezing. I doubt that anyone will even think about trying to get up there today without crampons, but I guess I don't know for sure. I have some pictures, if you can tell me a way to share them, or I can email them to you if you want.
