[Lowest min temperature winter 2014 - 2015 season]

The list I had was for the UK as a whole. I'm certain of this because Logie Coldstone was a frequently named location.

Maybe someone can find it. For some reason or another I've got the university of Dundee in my head in relation to it, perhaps it was compiled by someone there?Not 100% sure about that, though.

You are right about surprise minima, I'd suggest that temperatures close to -8C in southern England, without snow cover, is actually pretty good going. Yet on other occasions you can struggle with more favourable conditions, at least on paper.

 

The list is maintained by Trevor Harley - you are right as he is Professor of Cognitive Psychology at Dundee University.

 

He has put together a huge amount of material and his pages are found here: http://www.personal.dundee.ac.uk/~taharley/britweather.htm
