I was out and about in town at the time when this started developing, but not for long. I noticed strong convection sparked off early as the daytime heating got going in the unstable polar maritime air. I thought given the fact it was only 11 o’clock with slack air flow, there was good potential for some electrical activity.

I got home and trained the camera on the cell, which was now skirting the west of Macclesfield. A pronounced rain curtain and arcus cloud developed, showing maturity. Then it started discharging less than a mile to the south west. I caught a decent C-G strike and thunder by aiming the camera in between the updraught and the downdraught, where I came to learn most lightning hotspots of cold-air storms reside.

As it proceeded into the distance south-eastwards it gave some strange-shaped C-C lightning which was elongated across the sky.

The anvil was clearly visible as it left the area, being feathery in nature on the rearward edge. I presume the forward edge was more spread-out in the direction of the upper flow.
