I'll give it 3/10. The statistics (18 days snow falling, 4 days snow lying at 0900) suggest a near average winter snow wise, but they hide the fact that never did more than 1cm manage to settle, and only on one day (Jan 14) did snowcover last beyond noon.
Constant sleet or rain at 2C, snow that quickly turned to rain (including in one case a Cheshire gap streamer, how on earth did that happen?) and the most tiresome feature of 2014-15, the same places getting the best snow again and again. East Midlands (in a NW ly?), Manchester and above all the Peak District which seems to be a law unto itself regarding snow these days.
It also continued 2013/14's mystery of repeated clear nights that struggled to freeze, and never recorded below -4, or any maxima below 2C. The only anticyclone we had might as well nit have bothered, it gave a week of the most revolting grey muck day and night.
