was the monster that came in behind T0053 just 2 hours after. The cell was
spotted on the horizon before it came with explosive towers developing.
Looking at the weather radar on TV weather forecasts, it looked as if it was
an independent cell forming behind the main trough of showers that produced
T0053. It was clear that this was more organised and probably associated
with some strong convergence or even a new pool of cool sinking air.
it got closer a strong and defined arcus cloud (or roll-cloud) was evident
all the way along the west horizon.
was a constant background rumble of thunder caused by weak discharges taking
place just behind the arcus cloud that were only visible as very faint flashes.
I was expecting to see some C-Gs from under the arcus but throughout
the entire storm I didn't witness one single strike of the like.
got closer the arcus cloud demonstrated classic “Whales Mouth” formation dominating the skies and looked
hidden low-amp lightning continued in between the roll-cloud and the rain
curtain until finally giving way to a large smooth downdraft base in which
large C-Cs started to spark all over the show with return strokes and new
leaders. The C-Cs were still of low-amp nature but they looked good and were
bright compared to T0053.
This was one of the most fully-documented storms I have filmed in terms of
characteristics. The thunderheads were clearly visible and were mushroomed,
giving away strong and defined updrafts. Then the dark arcus roll-cloud pushed in with the
Whales Mouth formation, then a splash of C-C lightning within the core parts
of the cell. Then to finish it off, the dormant thunderhead sat opposite the sunset.
All it needed was a rainbow to put the icing on the cake!

T0053 was embedded in the arc of
convection seen across the Midlands, whilst T0054 is shown brewing in a new
line of convection positioned western Wales.
