I'd be more concerned w/ fruit tree buds. Down here weve seen the damage of late season cold. Fruit trees - Peach/cherry trees were devastated a couple years back.
Remember, snow is an insulator and helps ground plants/shrubs.
Blizz that is some crazy stuff were it to verify. Just peeked at overnights, and yeah, while progressive in nature, there is plenty of cold close enough for a well timed event to break for some late season love from above, and a few decent chances are showing.
