A low pressure system had joined forces with the one that generated Thunderstorm 0028 and was now filling in to the east of the UK dragging in cooler northerlies across the country. The centre was for a time right over the Pennines to the east whilst T0029 was being created.

It was a warm morning with the sense of humidity in the air, and strong convection had already started. The winds started from the east, and slowly swung to the north as the low-pressure continued its journey NE into the North Sea. I saw powerful convection to the north signified with an updraught base and a mushroomed-anvil. C-G was starting to occur under the base directly heading for Macclesfield. However it turned out it was a short-lived cell being purely sun-powered and started to dissipate as it got close, presumably as the convection process was killed off by its own Anvil. The video footage was somewhat ruined visually by back-garden bonfires and acoustically by angry dogs and traffic!

This is one of the few daytime storms I have filmed so far with strong updraught bases (Arcus clouds) where others included Thunderstorms 0019 and 0022. It appears this feature usually brings an abundance of C-G. C-G was the only form of lightning caught from this storm.
