13cm here. some got 20+ in Mendips, out Bath way and Somerset (add in further East overnight and today Wilts, Berks, Hamp.) Glos, Cotswolds, S Wales got into Northern Extent as did Ox) Further in town (Bris) probs a bit less but 10 to 12 cm widely. Cornwall, Devon got high moors action and unexpected sea level snow (include Dorset) - I saw Hayle and Newquay recording heavy snow - Main road over Bodmin got out of hand 100s put up overnight!. It was one of those nights where nowcasting was King and the models were "erratic". And it kept going all day today. Multiple, stalled and fully circulatory mesoscale features breaking away and feeding back into Occlusions and associated Upper Low fronts caused havoc (several times over the period)
