I’ve noticed over the years that the low moisture lake effect snow has a problem sticking during the day as you get into late winter and the sun angle gets higher. I remember probably about 25 years ago there was some very heavy lake effect snow squalls in early March. We had bare ground before that and every time it snowed hard, the ground would get covered but as soon as there was a lull, it melted. So we never gained anything. Also, a lot of times the cloud cover is actually quite thin during lake effect snow which doesn’t help either.
