Funny how us in Norfolk don't go into "OMG!!" mode when we get an absolute doozy of a storm! Initially only a couple of rumbles when it passed to my north, but within 30 mins it grew horns in a big way - I actually was in the van intending just to get some even cloudscapes so no tripod, remote blah blah as I really wasn't expecting it to develop as it did. I paused briefly on the way to Mattishall, superb IC and CGs, plus some large hail for a time, possible rotation but didn't get it on video as I was interrupted by the hail shaft! Stopped again at a good view point and just watched the clouds being lit up every few seconds, then went down the A47 towards Norwich still with this incredible light show as it got dark. Came back towards Wymondham via Marlingford (wind damage observed - branches and tree debris on the road for about half a mile) and stopped off again as I thought the tail ender would still be very active as it had been really chucking out CGs previously. However it all died off, apart from lightning still visible out towards the coast about 40 miles away.
All in all the best storm for a decade!
