There's no sign
of a post-Christmas mild spell, though, with the 25th to 31st being the
coldest part of the month.


In the 80's and early 90's the post Christmas week was usually the one
where the first snowfall proper would come in. There was certainly a
good few years (10+) where it occured more often than not.

Christmas was rarely white, Hogmany rarely green.
