For me the thing that puts the cold spell into a very cold category is the number of days where the average temperature was below freezing, we had 7 days averaging below freezing, and another averaging just 0.1c This is unheard off in recent history, especially as 4 of the days were in a row. Also the temperature reached -10 on 2 occasions, again this hasent happened for many years. I cant ever remember seeing temperatures of -3 at midday and -6 at 5:30 pm, this happened on a couple of occasions.
