My Winter Snow Events file has been updated to cover Winter 2006/07 (I think it's unlikely that we will get any snow in the first half of May). With a score of just 11, Winter 2006/07 was the most snowless, along with 1997/98, since 1991/92.
For those not 'in the know', the Winter Snow Events was largely inspired by L.Bonacina's 1875-1975 (recently extended to 2004) categorisation of past winters. I attempted more of a numerical/statistical analysis of the snowiness of past winters, aiming to include every snow event that occurred across lowland Britain for each winter, and awarding each snow event a score from 1-5 depending on how widespread and intense it was. The snow events for each winter are added together to give the winter's "score".
