Line of storms over from Surrey down to Hants beginning to back build to around 10 mile south of here, just south of Caterham, occasional sheet lightning to the south.

Gonna stick my neck out now and predict the hotspot for tonight will be within a triangle from Maidstone to Chelmsford and West to Oxford, don't ask me why, just intuition!!

I'm starting to get a little bit of a headache, sometimes a sign of approaching rain and/or storms

Got my old radio on, and I'm hearing the odd bit of distortion! Must be from them cells over Surrey, or that lot all the way in Holland? Anyone know he furthest range of detecting strikes on AM radios?

Storms just about keeping away from here, in fact the moon is out now! Surrey & E Hants may be under water soon judging by the radar. Can hear the thunder

I think it's about 20-25 miles.  Could be wrong but I think that's about the limit.

20 miles if you tune to a blank frequency with no broadcast carrier signal. If you tune to a weak station you can hear strikes from where it's transmitting from, so best tune to a blank spot for local accuracy.

The Holland/Belgium cell (or at least the lightning strikes) now seem to have made a right and be heading North towards Amsterdam. If showers keep developing along that line from Surrey up to London, we may get something here before too long

I see. Well I'm in excess of 100 miles from the nearest activity and it seems to be corresponding with the Surrey storm. I'll hear a crackling and then on lightning maps, it shows instantly a split second after. I've got the volume pretty high though!

Does anyone have any idea what level the cloud tops were at in that W London cell this afternoon? Looking on the Europe cloud height map it just said 10km+, so a minimum of 33000ft or so.  It looked closer to 40000+.

I could see aircraft at cruise level avoiding the storms, the contrails were noticeably displaced by the tops after too.

P.S. I did an experiment 25 years ago with my Amateur radio equipment. Back then I only had local press and TV news to confirm my findings, plus other radio operators. 20 Miles was about the max distance for a portable radio!

First loud rumble of thunder of the evening just then here near Croydon, building closer!

Really ought to get some sleep, but now that's coming closer, might not be able to.

And as I wrote that, I heard what MIGHT have been an incredibly distant rumble
