Just got back today (Monday) from the Kearsarge Pass area. The switchbacks leading up to and down from the pass on either side should not be a problem; they have thin strips of snow along the trail that are easily bypassed if need be, and they are not dicey by any means. Your problem will be the approach to the saddle where you first gain views of the pass; particularly the rocky section right before Gilbert Lake and the trail right after it and up to the saddle; there is snow on a good part of the trail, particularly on the switchbacks right below the saddle. When I hiked up Friday and Saturday the snow was soft and passable, but by today when I hiked back down from Flower Lake, the slushy snow had frozen into ice for a good part of the trail, and this was the middle of the day; fairly slippery in parts, and I expect the switchbacks below the saddle were the same. It is forecast to be below freezing even in the daytime for Thanksgiving, so my thought is you will need some sort of traction device at the very least; I think crampons might be overkill lower down, but good for the switchbacks. It depends on how comfortable you are with this kind of terrain. Expect intermittent snow and ice and clear trail. I hiked down the pass and to just east and above Bullfrog Lake; patches of foot deep snow in some places but nothing spectacular. Fairly dry in most areas. The lower trail bypassing Kearsarge Lakes is another matter; looked like more snow in that area and the Lakes are frozen. Can't really say much about Mt. Bago and the need for crampons, but figure it'll be fairly icey this weekend. It looked to have some sections that were fairly free of snow, but this is observation from a distance. Hope this helps.
