just to give everyone an idea of just how mental it is over in EA, have a look at this screen grab from  lightningmaps.org      the screen grab represents roughly 15 miles north to south...holy smokes!

What a storm that was - flash, bang, wallop!

[Delka]

I was out in the North-West Norfolk storm this time! I left the house 2 hours ago and saw the storm brewing across the sea but thought nothing of it as it was obviously ages away. Then slowly as it approached the rumbles that were turning into a constant echo frightened all the tourists watching along the seafront. The beach went from busiest its been all year to completely empty in 30 seconds when the first drops of rain came down. Most amazing sight seeing constant sheet lightning and loads of CG, then it came right overhead and I was stuck under a tree at the beach until 15 minutes ago when I made a dash for it, then a rainbow appeared whilst distant rumbles continued. Best most lively storm I have seen in 5-10 years, I can't explain the amounts of rain, the cloudscapes and lightning and the sheer amount of it, words don't do any of it justice. Shame I didn't take any photos, I was just stood there speechless.

Nope, wasn't like that at all - split just as it got to mid Norfolk, 3 rumbles of thunder and about 10 mins of light rain. Not what I'd call mental unless I was completely desperate!

so, it wasn't bad for you......that's a shame, but for many parts such as Southwold, the lightning detectors and the web cams were not lying, it was a multicell complex the likes of which we don't often see in the UK

Shame, up here it was madness, best storm in many years!

Jesus, lucky much! Just insane rain up this way, never seen hail that big in the UK...

It's weakening quite significantly over Norfolk - south Suffolk and the far north-west corner of Norfolk/south-east corner of Lincolnshire are getting the worst (best?) of it.

It always does - no idea why unless the boulder clay plateau has some sort of influence, although I was lead to believe it was an enhancer. Normal for Norfolk so no change there. Still August and September to go........and be disappointed yet again.

Would you classify it as a mesoscale convective system, ajp?

[Methuselah]

Well it was certainly a humdinger!

Oh I saw it coming, trust me, the anvil was huge radar said direct hit right up to barely 10 miles out. However it literally split as it approached, you could see it happening. Now why that happened I have no idea, but it's not unusual for storms (big or small) to suddenly divert north or south of here. Must be some sort of local topography (which in a relatively flat county is hard to conceive!)

Mine were just a tad bigger last July 1st, but they're impressive. Is everything safe and sound?

We've often speculated that it has to do with the pattern of the river valleys which cut through the plateau, but that wouldn't apply where you are, as we think of the western border being the Tiffey valley.

Have had a great view of the Suffolk storm cloud from my back garden. The anvil is huge. Front is covered in mammatus, so would look spectacular underneath it and a long line of cumulus feeding into the back. Haven't seen any lighting though from this range. Thought I could  see a cylindrical hail core at one stage.

I personally wouldn't, at least not in the sense of a classic 'european' MCS......rather discrete thunderstorms that fired along a frontal boundary, expanded given the enviroment they were entering......for me, the clue is that the cells waxed and waned, at certain times during the past couple of hours, some of the cells faded, whilst a neighbouring cell fired, this can be seen on the lightning/ppn spreads of the cells over time

We are good, next doors conservatory has holes in the roof and cars are covered in dents.

[Staffordshire]

Well a bit congrats to Roger who called the past 24 hours almost perfectly... Well done sir

Evening peeps,that looks like a hell of a storm in Suffolk,anyone got any footage or pics

well i took a drive down the M1 to intercept that Stoke storm,it was 50mph most of the way down(dam roadworks) but did manage to get in front of it and got off at Duckmanton to head for Bolsover castle of which was on top of a hill to get a great vantage point,the storm didn't look much as it was dying out but i was gobsmacked at how much thunder came from this,there was hardly any rain falling from it either

little classic cell that was rotating and the lightning was coming from that shaft to the right every few seconds

and this shot after it went over with the inflow coming from the right of the picture

i have a couple clips which i will look at later and upload when i have the time
