I saw this idea somewhere else and thought that it would be interesting to do for the main media outlet control city (KMCN-Macon, GA) in my region. The analysis regarded Christmas weather by the decade with each 10 year period daily high/low for the date forming the decade average. Unlike some other cities in the region, Macon's weather history is only documented completely from 1900 onward.
1900s High 56.6 Low 39.3
1910s High 57.0 Low 37.3
1920s High 57.3 Low 35.5
1930s High 61.7 Low 39.5 (the early 30s featured some of the torchiest Christmases on record)
1940s High 53.5 Low 39.5
1950s High 57.4 Low 40.6
1960s High 54.2 Low 32.3
1970s High 60.6 Low 40.0 (the early 70s also had warm Christmases)
1980s High 54.9 Low 37.9 (it was either blistering cold or insanely warm every Christmas in Macon this decade)
1990s High 53.5 Low 30.6
2000s High 56.2 Low 37.8
2010s High 60.1 Low 39.0
2020s High 53 Low 30.6 (so far)
I found it interesting that the Christmas weather for the immediate Central Georgia area has actaully somewhat trended colder in the last forty years compared to how things were in the earlier half of the twentieth century. I know that we all are upset over the recent deficit in terms of wintery precipiation, but there's been other periods in the not so distant past (at least in my general area) that were largely devoid of continuous winter storms. For example, my grandmother was born in 1936 and she's stated several times that she cannot remember it ever snowing when she was growing up outside of when she was extremely young (the famous January 1940 storm) and this time period would correlate with the noted snow drought that the southern half of Georgia had during most of the 1940s-1950s. On the flip side, my great grandfather (her father) was born in 1899 and he would often tell stories about how it routinely snowed when he was younger. This would correlate with the decade from 1895-1905 that argubably is the most active in history for the southern half of Georgia in terms of wintery precipiation. These patterns seem to be so cyclical in nature at times, everything just has to align up perfectly.
