What a day!


For those of us in the SW, the pictures on Spotlight are going to be
interesting!


For those not living in the South West, but have SKY TV, and would
like to watch spotlight, try Sky TV Channel 987.


There's some video footage here toohttp://news.bbc.co.uk/1/hi/england/devon/7700167.stm

The storm cannot have had a supercell structure or the hail would
probably have gone up and down a few times before finally falling out
as large hail.

I think the hail was carried along in 'rafts' similar to logs. It then
accumulated in a few small areas, hence the very localised large
thicknesses, and amount of muck mixed up in it.

A very similar, though much less severe, event happened in Padstow (I
posted a link to a video earlier in this thread.) I know that in that
case rafts of hail floating on the water were carried to the bottom of
the town and piled up 2 - 3 feet deep in places, whilst 100 yards away
there was virtually none.
