I was going to mention earlier that October 2019 was the 4th coldest on record at SLE behind only 1919, 1893, and 1949.
It was also the coldest September-November at SLE since 1985. Another fun note, 1985 was the coldest calendar year on record at SLE. At the time it was the driest year on record too, though that has since been surpassed by 2013.
