We had accumulating snow in May last year. Not sure anyone thinks we get a killing snow at any point now. That gfs depiction of 2 to 3 feet was a unique and rare sight for an April snow map. I doubt any snow now bothers the plants. Temps in the low 20's would be painful I guess. But it went down to 21 here twice in the last two weeks and nothing seems too damaged albeit its still not in growing season apparently as nws did not issue a freeze warning.
