This was a classic Spanish Plume system bringing some of the heaviest
thunderstorms to Western England and Wales in a while. The storm cell that
came closest to Macclesfield appeared to be the core development region
which reached its peak as it approached the Pennines, probably enhanced
further by the orography.
The whole night was a
repeat performance of T0026. We had a few dissipating cells roll in first,
giving a few C-Gs and C-Cs with evidence of Anvil Crawlers looking in
between stratocumulus and high-based cloud ahead of it.

Then the back edge
(south side) of the cell cluster came in rich in severe I-C and return
strokes. The whole multicell was enormous looking at the radar and satellite
imagery at the time. However as T0026 did, it rolled over and behind the
Pennines nowhere near Macclesfield giving almost continuous I-C lightning
with return strokes, which was a spectacular sight from a distance but
merely appeared like a distant night-raid in a war zone. Like T0026 it had
an average discharge rate of 6-8 seconds at times, however the display was a
little better than that of T0026 overall. There was a brief downpour of rain
in the Macclesfield area as it left the area and extremely gusty winds.

The same front (as it was now stationary over the spine of the UK), would
later help the development of T0036 with its strong upper-level northerly
jet adding vorticity to surface-level convection running in from the west at
surface level.
