It's a challenge we play up here every year. Snow can actually fall in September and we had 3 MAJOR snowstorms up until Memorial Day just a few years back. My sister-in-law refuses to turn it on until Oct. 1st - I am weak and I caved. The overnight temperature was about 34 and the daytime high barely into the 60's. The house got down to 65 degrees and I turned the heat on.......
From Skaneateles Lake - the most beautiful of the Finger Lakes...people don't expect the state of NY to be so cold and snowy. We get Lake Effect snow from 2 of the Great Lakes.
