True. We moved from NNJ to BGR in January 1973 right after their snowiest December on record, and immediately had 40s when the normal is 20s. Got a moderate snow in late month, quickly extirpated in a torch/deluge, and that was it for real winter. The next winter began with the snow-to-downpour event in mid-Dec that had us with RA+ and 56° while my parents in NNJ were at 15 with IP (and western SNE was hammered by ZR), and 1973-74 was only saved from being BGR's least snowy by post-equinoctal storms. Mid-90s in July 1974 then 102 on Hot Saturday the following summer - never had a real "Maine winter" month until Dec 1975, our last in BGR.
The effect didn't carry over to our Jan 1 move to Ft. Kent - the minima for 9th-13th were -33, -36 ,-24, -41, -37.
