I started March 13 last year, and hit two snowstorms. The first was just before the smokies (March 30) and dropped about 2-3" Where I was, but several inches more just a few miles north on the trail (where it was higher elevation, actually in the Smokies.) It was a lot of fun, got to make mini-snowmen and stuff. The second was April 15, and it dropped a lot more snow, drifts around 2’ deep. While post-holing wasn’t much fun, I still wouldn’t say carrying crampons or snowshoes is really needed. There’s only a small chance that you’d use them if you had them, and you could just as easily stop in a shelter and wait a day or two for other people to pack the snow down
IMHO, the best idea is to carry plenty food, water, and clothes which will are nice to have regardless of snow levels. Most importantly, use your brain, don’t walk if you don’t think it’s a good idea.
