LoisW, throughout all the next week, weather is running a heat wave. Whitney summit LOWS are in the mid-40s, with highs in the upper 50s. There will be almost no difficulties encountered by your trip dates.
Everyone: We REALLY need new pictures of the trail conditions! If you go, and can snap off some pictures, send them my way -- email me (view my profile, or just email them to the "Contact Us" link at the bottom of every page here. Particular spots: + Above Trail Camp, first snow on the trail + At the cables, looking up, and then looking back. + At the top switchback where people have trouble crossing the snow at the top of the chute. + Any even slightly difficult spots between Trail Camp and the summit.
