Big one on the south coast last night, went on some time and some big bangs... One massive one which finally fully woke me, though none of the rest of the family heard anything!!
You must be near me then, east side of Bournemouth. I don't know about biggest overall, but certainly that one strike was one of the single loudest I've experienced!
In Torbay about 11/half past last night there were some flashes and distant thunder. Nothing big though... Not that I heard anyway. I left the window open because I love to watch lightning storms so I will be a bit upset if it was big here!
Weather warning from 13:00-22:00 in Leeds but no sign of anything yet. It's bright with plenty of cumulous clouds knocking about but it's been really muggy all weekend so hoping a good storm will clear the air.
