I have heard she was in a bad state. Can't confirm, but supposedly someone had to always be near her when the kids were around. Dad goes to get take out and this happens. It's just such a tragedy.
I haven't had all or nothing seasons last several years. Been sort of consistent except 19-20 which was meh. However, my snowfall seemed to come in 3-5 week stretches vs spread out.
I also took Ray's point under the climo regression idea. IOW, eventually at some point Climo tries to even out and eventually get back to the long term norms. I think that is what Ray meant by odds.
