I`ve only ever known snow on Christmas Day once in my life so no, I don't think we'll get it. I`d love to see it but I have a 200 mile drive back to work after Boxing Day and don't fancy encountering treacherous roads.
According to the Guardian, snow has fallen in Scotland on Xmas day 37 times since 1960; 16 in N Ireland and 16 in Wales. While England is split norf and sarf; the good old North of the country has had 26 white Christmasses compared to the South's 10. Food for thought.
