PSU also has a rule of thumb type of thing where the odds of a certain type of snow season are based off of when his area records an inch of snow for the first time.
It’s been a while since I saw the post but from what I remember it was something along the lines of if he gets his first inch around December 1st then there’s a good chance of a blockbuster winter, if it’s around this time of December then there’s good odds of reaching climo, but if it’s in the lead up to New Years and beyond then it’s going to be a dead ratter.
