Since Buffalo is in their top 5 highest snowfall ever this season, it seems they chose to include their highest snowfall instead of lowest snowfall. Their rank for Buffalo also reflects the highest and instead of lowest. It's the only one on the list like that, see the footnote on the bottom left.
It doesn't make sense to have Buffalo ranked the same way as the rest since it's one of their snowiest winters ever. But the rank for the "least snowiest" would be #136 and 1918-1919 25.0" for the record.
There is a typo on there though somewhere else
