Spent the evening up at Mam Tor watching the cell come over from Nottingham,not much in the way of lighting over the peaks,one decent CG seen. Was pretty surreal as the most intense part of the storm approached seeing the Hope Valley completely disappear with visibility for about 30 seconds down to no more than 50m. Strong winds followed straight after and could see full distance again within a minute. Attached image is as the storm headed towards Manchester seen from Ladybower Reservoir.
