Of the data I have from 2009-2019, there was a white Thanksgiving every year except 2009, 2012, 2015.
2017 appears to have been somewhat marginal in the snow department, but I'll allow it since it showed 1" depth that year. LOL
So 70% chance based on this small sample size. 18" on the ground for Turkey Day 2018. That is pretty epic.
