The Wokingham Hailstorm (which was a forward flank updraught hp supercell)
of 1959 was when the supercell structure was first postulated - this was the
first storm ever to be extensively tracked on radar. There's more on these
events in the usw FAQ / glossary.

They are not common in the UK (reported once every 10 years or so) = but =
smaller
scale events (rotating single cells of shallow vertical extent /
misocyclones / mini-supercells!) may well
be... i've got a pic of a local smaller scale rotating single cell event in
my photograph gallery he

which shows an inflow band into a rotating single cell thunderstorm in deep
cold air.
