A "special" type of storm swept across the country on Monday.
The storm, thought to be an unusual "supercell" storm, travelled through the south Midlands, bringing rain, large hailstones, and a tornado in Oxfordshire.
Richard Glazer drove through the tornado with his wife and son on the A34 near Kidlington, Oxfordshire:
Footage of the tornado is on ITV Meridian.
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 US than the UK.
Brendan Jones, forecaster at Meteogroup, the weather division of the Press Association, said:
Mr Jones said it was unlikely there would be another supercell storm in the coming week, as they require very specific atmospheric conditions, but forecasters have said there was a "definite chance" of further thunderstorm activity.
