Shame there is no thunder in these showers, because after this, we won't be having any weather for ages.

Nice structure on the current cell which is belting out one hell of a downpour.

Just caught the edge of another shower giving moderate rain. Also another one passed further east. Seems similar to last week where all the heaviest showers go either side of here.

Loads of puffy cauliflower heads and some small towers going up in tower hamlets a couple of hours ago. Sky is black now and very unstable looking.

Day 1 Convective Outlook

VALID 06:00 UTC Tue 02 May 2017 - 05:59 UTC Wed 03 May 2017

ISSUED 04:41 UTC Mon 01 May 2017

ISSUED BY: Dan

Cut-off upper low will become centred across eastern France on Tuesday, but still sufficiently close to S/SE England to provide some cool air aloft and marginal instability in response to diurnal heating. A few scattered showers are likely to develop during Tuesday afternoon, enhanced by low-level wind convergence and thence moving generally S/SW-wards in the flow, perhaps marginally deep enough to produce some isolated lightning.

Skies have looked modestly threatening for rain all afternoon and finally we have some sporadic heavy downpours here in south London.

Felt like months since I last heard thunder, but my craving for it will be satisfied as I head stateside to deliberately hunt for storms next Monday.

Nice. I've always fancied seeing some supercell storms. Hope you get plenty of storm action over there. Good luck mate.

Wonder if we'll get anything else today or if that's it?

We also seem to have a northerly wind. I could be wrong, but I'm sure an easterly was forecast? There is a bank of rain sitting just to the east which could be blown our way had we got an easterly. Frustrating.

This afternoon there's been some lovely cloud formations here, including Undulatus Asperatus and what may have been Mammatus, but with it has just been nothing more than the occasional shower.

I think we've all missed the boat for today - convectively speaking.

Really did look like there would be at least some heavy showers about but it's all just fizzling away. Probably the early cloud cover inhibiting the necessary diurnal heating needed to spark anything off.

I know there was only a small chance of lightning today but was this afternoon a good example of having instability but no trigger?

Instability was poor today, and lapse rates not much better either. I probably need to be educated but I would not have seen any potential at all today.

So far it has been a very quiet season and I am still yet to dust off the storm chasing equipment that has been out of use since last October. I am hopeful that the odd sneaky plume type charts showing in FI are a sign of things to come.

I based my very limited expectations on a low risk from Convective Weather and was aware there was marginal instability but figured that was still enough for something brief given the right ingredients.

I think instability was only even remotely good down in the far south but it shows when you look at what the skies were like earlier on.

I too am looking carefully at FI charts, you have to speculate to spectate!

Yep, that looks like it for today. The chance was low admittedly, but that doesn't mean one can't hope! Still waiting for my first proper storm of 2017 (although that single ic flash and two rumbles last week was still fun).

Some very threatening skies this afternoon here, looked like a supercell was forming but got a bit of light rain instead. Only in the UK, the land of apocalyptic skies that deliver........not much.

No storm here today, but we did get some extremely heavy rain and some small hail; enough to create some minor surface flooding. There was also some nice structure on the last shower that came through before it got dark.

Still more than what we've had here!
