THUNDERSTORM T0053 This storm was just starting to move in after I’d got in from work - well timed. It was moving in quite quickly and on first impressions was obvious to most that it was likely to be electrified, especially given the airmass being a heated returning polar maritime. There was a strong and organised updraught evident at the front, judging by a linear arcus cloud with a dense rain curtain right behind it (less likely to be dry outflow). The parent weather system was actually the signature of ex-hurricane Bonnie, and it still had some energy contained within it even as a mature extra-tropical low. This storm was one of two (T0054 came just a couple of hours after with even more power).
This storm was difficult to film as it didn’t really do much visibly under the base. The C-Cs were plenty but of low to mid-amp nature, and were barely visible within the rain curtains and daylight. However the discharge rate was good at an average of only 54 seconds. This storm patrolled northwards along a band of fast-moving cells and was visible in the distance. However the show wasn’t over when T0054 followed in behind proving to be a lot more spectacular, perhaps because it was riding an upper trough.
