This storm was powered by an active set of troughs ahead of a parent occlusion running into warm air, rich with C-G strikes as it developed along the triple-point of the low in the north-west region of England along with Macclesfield. The cloud base was quite high resulting in some high-amp C-Gs and notably explosive thunders. Unfortunately the C-Gs proved difficult to follow as the storm drew closer and were all off-camera, however the back-flash from the discharges were bright enough to be picked up against the daylight.

Along with some excellent thunder sounds, the soundtrack of the footage also gave away click sounds as each C-G discharge occurred. This is usually caused by a notable electromagnetic pulse from a strong (or close) lightning channel, but as the discharges were still at some distance this further gave away the C-Gs high-amp nature.

The storm system continued northwards towards the Manchester area after giving torrential rain over much of the North West region.
