On a somewhat related note, it is going to be that warmer and wetter than normal this week weather wise for my locale, however, Environment Canada also lists for Christmas Day and Boxing 1982 as the warmest with it being 54.5 F and 50.5 respectively. Also, the wettest Christmas weeks were in 1941 with 1.4 inches of rain received on Christmas Eve, 1.02 inches on Christmas Day 1979, and 1.25 on Dec 29 1940.
I get the impression that the media likes to portray years past as having picture perfect Christmas season weather, however, as one can see, weather extremes have gone on for forever and December has always been very up and down (at least in my locale). BTW, I converted the numbers to make things easier for people here.
I’d expect some climate disruption from 5-7 years of full-out World War II...
But I haven’t seen any references to it.
