A tornado raged over parts of Britain yesterday as a 'supercell'
storm swept across the country.
Forecasters said there was a 'definite chance' of more thunder and
lightning after the unusual storm made its way through the south
Midlands, bringing heavy rain, large hailstones and a tornado in
Oxfordshire.
The thunderstorm started in Wiltshire, and moved across
Oxfordshire - where a tornado was reported in several places
including Bicester, Eynsham, and Kidlington - then moved to
Buckinghamshire.
Richard Glazer drove through the tornado with his wife and son on
the A34 near Kidlington, Oxfordshire.
'It was very wet, we were just driving on the A34 and looked up
and realised one part of the sky was moving in one direction and
another in the opposite direction,' he said.
'I thought, "that looks like a tornado!" We pretty much drove
through it, we were right underneath it.
'As we drove into it the trees were blowing left to right and as
we got through it they were blowing the other way.'
The 40-year-old, from nearby Witney, Oxfordshire, added: 'It
wasn't particularly big but it was amazing to see the change in
the environment. It was grey and a bit blurry and then to be hit
by something like that. You suddenly realise the force of nature,
it's incredible.'

Forecasters said it was almost certainly a tornado, and the storm
that caused it was thought to be a supercell storm - more commonly
seen in the U.S. than in the UK.
Brendan Jones, forecaster at MeteoGroup, said it was unlikely
there would be another supercell storm in the coming week, as they
require very specific atmospheric conditions.
You might not believe it, but the UK is actually a tornado
hot-spot.
The tunnels of wind are five times more likely to appear in
Britain that in the U.S. - and we also get more of them than any
other place in Europe.
At least 100 tornadoes strike Britain each year - such as the one
pictured above, which touched down in Darlington last month - but
they are not always spotted, and just 30 are reported each year.
A tornado is defined as 'a fast-moving rotating column of air,
usually with a funnel-shaped cloud that extends to the ground'.
The U.S. is better known for this unusual weather phenomenon,
where tornadoes can be up to half a mile wide and top out at
300mph. In the UK, our twisters are likely to be a couple of dozen
metres wide with a top speed of 120mph.
However, a particularly big tornado in January 1998 caused more
than £10m of damage in the town of Selsey in West Sussex.
However, heavy rain has been predicted for much of the country,
which could bring more thunder and lightning, Mr Jones said.
He continued: 'It's going to remain unsettled, there will be rain
and showers around and there is a definite chance of more
thunderstorm activity.
'This particular thunderstorm developed over the northern part of
Wiltshire, and then gradually over the next three hours that storm
tracked through Oxfordshire and into part of Buckinghamshire
before eventually dying out before it got to Cambridgeshire.
'That's quite far for one thunderstorm to track.
'At the moment it's difficult to say exactly where the tornado was
because while the parent thunderstorm travelled all the way across
the south Midlands, it wasn't necessarily producing a tornado all
the time.
'There has been more than one report of a tornado beneath this
storm. There has also been some quite big hailstones.'
He said it was likely the storm was a 'supercell' thunderstorm -
unlike normal storms, the air in supercell storms is spinning or
rotating, he said.
'There are suggestions that this thunderstorm was a special type
of storm that we don't get too often in this country. That's a
reason why it was able to last for such a long time,' he said.
He said the UK had seen plenty of reports of tornadoes and funnel
clouds - which do not touch the ground - but not supercell storms,
adding: 'This one was fairly special.'
The storm comes less than two weeks after high winds tore through
Rugby, Warwickshire, blowing the roof from one home and damaging
others, described by some people as being like a 'mini tornado'.
Another tornado was also reported to have happened near Halstead,
Essex, on the same day.
