These storm cells were produced ahead of a Cold Front approaching from the
west lifting warm air travelled up from the Bay of Biscay. A genesis point
for intense cells passed right over the northwest region and was stuck for a
while whilst the upper level winds carried the cells slowly in a
north-westerly direction. The result was fantastic sequence of organised
slow-moving storm cells with large mushroomed thunderheads. In total three
separate cells were spawned in the East Cheshire region. C-Gs were abundant
in all three cells in the footage.
Cell 1
The first cell floated over the Pennines to the east giving some
impressive C-G shots, whilst the front kept producing cells to the south.
Cell 2
This was a newly developed Singlecell to the Northwest that produced a
fantastic long C-G, possibly a positive flash as it reached outside the
cell. That was a lucky capture as I had only just moved the positioning of
the camera from Cell 1 to Cell 2 on a hunch it was active.
Cell 3
A couple of minutes after that, Cell 3 started kicking off to the south
which was closer and started moving overhead, so I repositioned the camera
again.
A
close C-G strike that was slightly missed off the edge of the camera view
was the closest discharge of the evening, and the front continued
development of cells further north and east giving way to a spectacular view
of mushroomed thunderheads, undisturbed by the strong upper-level winds.
