A
late warm spell in October was about to end with instability breaking out
ahead of a western-approaching cold front (running up against a continental
plume) producing some active cells along
a line across northwest England. Much "heat" lightning (clouds and
stratosphere above lighting up
from the distance) was observed on the western horizon
before the Sun came up.
However, the main cluster of storms largely pulsated northwards to the
west of Macclesfield out of sight, leaving a long line of hanging glaciated
cloud with mixed altocumulus and altostratus with embedded Castellanus (all
high-based) which was producing moderate rain. As the activity trundled
eastwards overhead, I left the camera rolling on its own in case of the odd
strike. It paid off as a lone high-level C-C
occurred directly in shot of the camera at a random time, which looked good in digital video. I called
this shot of activity “Cell 2” as it shared the same system. A further localised cell
developed later to the west (Cell 3) giving a few distant rumbles of thunder before
it all fell silent.
The main cluster
of storm cells (originally showing heat-lightning to the western
horizon) continued into the Merseyside and Manchester regions giving
some spectacular lightning displays. Some photos were sent into the
BBC including an impressive C-G shot by "Tony from Wigan". I also sent
in my shot of the C-C and both of our photos were used in a special
report about the storms as damage was caused by the lightning striking
houses and telephone lines.
