I posted without reading yrs Paul.Am I right in thinking these are examples where MCSs eventually
formed and that the possible supercells occured in the early stages?What's yr assessment of the
radar imagery in these cases?

David,
I must admit to not having seen the radar pics for a while now, but
certainly from personally seeing one of the June 7th, 96 storms, it
had an appearence of a supercell (in S Oxforshire) with a beaver's
tail, wall cloud and mid-level striations. The latter event certainly
ended up being an MCS, but the individual cells may well have been
supercellular. The former, I believe, definately had several discrete
supercells as several severe hailstorms occurred in much different
areas, before the storms eventually congealed. This often occurs in
the US as well, with disrete supercells eventually forming either into
an MCS or a squall line, depending on how strong the upper forcing is,
and what orientation the wind shear is i.e. unidirectional or veered
shear.

Paul.
