I have mused on a 16 year cycle of severe winter weather beginning in 1947.
The next event was 1963 with 1979 after that.
The theory falls apart at that point because the next event should have been 1995 and as far as I recall that was not a severe winter.
Moving forward the next event in the cycle should have been 2011 - following December 2010 - but of course the severe weather tailed off before January began!
