Location is Reading now (first summer at Uni). Produced from a cool and unstable polar/arctic maritime flow post-system. These cells (2 in this instance) were reaching maturity as they took in the inland surface heating across the Midlands. However this particular cluster was weakly electrified and hard to film from my hall, however the cloud shots were good and the second cell produced some C-G and possibly a positive flash (P-F) which produced a long booming thunder.

Cell 1 and Cell 2 were the first two of an array of cells to cross Reading on this day. There was a short lull between the two cells which I didnít feel was long enough to class them as two separate storms. They were probably sharing the same anvil. However, behind these two cells a strong convergence zone was setting up and approaching, which shortly after produced T0045, an incredibly active squall-line that left these two cells shouting without a microphone.


CELL 2 (3rd shot is the C-G)
