T0048 was a very slow developing, slow-moving storm, quite weakly
electrified and had a low precipitation echo looking at the radar. Although
weekly electrified, it had a steady discharge rate give or take a few lulls
in activity. The line of activity was associated with an upper-trough
feature releasing medium and upper-level instability.
The storm approached in
twilight and was visibly flickering away in the distance, but became
irregular in activity as it dissipated and new cells developed behind it. I
saw virga in the twilight before the storm hit. The best part of this storm
was when it eventually made it to Macclesfield and produced a large C-C
discharge (although low-amp) overhead.
After that the storm
cell dissipated completely, however a couple of hours later the same
system generated T0049 directly overhead which was a completely
different story.
