The last time I went to get these peaks, I had driven through horrible snow and the nerves just got bad enough that my body determined that it wasn't happening that day.  I hiked in to marcy dam and turned around.  This attempt, I came in from upper works.  It was a very wet day, and was predicted to be a wet day with on and off drizzle in the morning and warming temps in the afternoon.  The drive in had a couple spots of black ice, but it wasn't a horrible drive in.
