This storm occurred in the late afternoon, apparently as a convergence zone
lying across Cheshire and Manchester. Vertical wind shear was excellent as
we had a light southerly flow accompanied with a fairly strong west-southwesterly
upper-flow. It seemed to be developing
quickly in places with a strong updraught bases just south of the rain
curtain (which was to the north). There were only three close discharges
throughout the duration of its passing - two of them were close directly in
the camera’s view, but slightly faint with the off-chance one of them was
accompanied with a C-G judging by the loud crashing thunder it produced.
As the convergence line
shifted east shortly after the discharges, there was a torrential
downpour of rain with mixed pea-sized hail. The cloud base after the rain
had cleared was very photogenic with turbulent rolls of stratocumulus mixed
with the cumuliform bases.
