Certainly notable this cold front, looks like we had a drop of about 5C in a short space of time in Manchester City Centre. We also have another observation site at Holme Moss (524m asl), the present weather sensor was reporting light snow not too long ago with a temperature ~ 1C. After the last cold spell there was about 8" of snow, but difficult to measure because of the drifting!
