The last 90 minutes has been pretty good where I am, admittedly the other side of Durham.
Had 3 inches/7cm of new snow when I last checked - had the ruler out before you ask.
Even now I think this event has been quite impressive and certainly surpassed my expectations. Heaviest precip probably passed but still some moderate snow for a few more hours and could easy be 10cm of new snow overall by morning.
Edit: BTW, I'm in Nevilles Cross not Dalston, 100m asl.
