There is never really too much snow on Skyline. During March, there will be a lot of people up there weekly and a well beaten track will be put in. Just don't go during or after a storm unless you know the way.
The worst snow I've experienced was after a storm once and the snow level reached down to the 4,000 ft level. Since it was a weekday, I broke trail with snow hip deep at times, but you probably (emphasis on probably) won't experience anything worse than that. If you go on a weekend, the very fit locals go routinely and will 99% of the time have broken in a nice trail for everyone.
Nice job!
I have to do that hike one day...I could have a slot of time to do it in early March, but I am assuming there will be too much snow above 8000ft then huh?
