yesterday is wandering its way across NW Europe - the overnight
rainfall radar returns showed that the 'line convection' element was
particularly fine (for a meteorologist!), though not perhaps if you
were actually underneath it. I've put a simple composite at this

Note the very long, near-continuous linear featu the books talk
about ' hundreds of kilometres ' in better examples; this one was at
least 1400 km with only minor weakening & lasted many hours as a
coherent feature.

These features can spawn hail, thunder and tornadoes - not sure if
there are any reports of such activity though.

This cold front produced a damaging wind event/minor tornado at
Knodishall, Suffolk (~14Z) as a wave feature moved along the line.
Could anyone with more information or an AWS in the area contact me,
thanks,
