you must be joking northern rab, ardnamurchan is nearly in Iceland!!
you're right about the ECM though, i think we look for temperatures of 25+, where out of the wind and in the sun 18-19 can feel lovely. I suppose the GFS is offering a much wider margin for change though, I'm liking the way it settles things down and could hopefully set a trend for the summer but the chances of that.....
