It was cool at the trailhead with sunny skies, and light breezes. I doubt the wind was ever over 30mph even on top, and the temps were probably in the 20s. At the trailhead, I left a water bottle out overnight to help guesstimate the low temp. Both my buddy and I agreed it was probably in the 20s at our campsite about a half hour before the "official" sunrise.
The snow was nearly non-existent, and the only solid "ice" we saw was in the bottom of the summit windbreak shelter. Based on the best weather data I could find for the past few weeks, there would be less snow now than when we were there. Unless there have been recent storms, I'm sure you could still go with regular footwear.
