Thanks for your posts, Puggit!

Is there any truth in the "long range" forecasts? 2-3 weeks ahead..

Ack - this has been a strange summer. This time last week we were staring down the barrel of an Atlantic driven summer according to the charts. Then 'poof' - another hot burst. You may have noticed the last few years have been dominated by these bursts, and no real extended heat waves.

Shame the storms have mostly skipped the South - still waiting for a good storm this summer.

Humidity and heat quite intense in Gerrard's Cross. Huge clouds to the east, not sure if something brewing; I'm no expert...



ETA: photo, aside from being rotated, does not do justice to the size of those clouds

It's clear from West Berks too. They're over London and heading ENE.

Central South misses out again - East wins, yet again

[Puggit]

The south is going to get some prolonged rain tomorrow. Yeah, I know, but the gardens need it

[Puggit]

Warm weekend and nationwide heatwave looking good after tomorrow's rain...

Not another one?

Different to the humid plumes. More likely to be steady build up with high pressure nearby.

[Puggit]

Remaining hopeful, but not certain, of a high pressure period of summer

Meanwhile, in Spain tomorrow:

All a bit up in the air at the moment regarding high pressur, it's definitely looking less likely.

But we do have another plume, peak temps likely next Weds at 31oC ... https://twitter.com/metoffice/status/8854613366915...

Spanish temperature record broken today - 47.3

Great .gif showing how that extreme heat will make its way up from Spain, and then get blown away by some really cool air.

I've enjoyed this summer so far in the main, long may in continue

It's been cold and miserable in Scotland though.

Try not to laugh to much

[Puggit]

I come bearing bad news. After the very short lived and not particularly amazing burst of heat early this week, Weds sees the Atlantic push the warmth away and then low pressure is set to sit over the British Isles for a while. The coldest air in Europe will be here.

Scotland will bear the brunt, the South will occasionally receive a little heat from the Continent.

I'm off to France on Saturday - see you later suckers :wave:

[Puggit]

What we do know - low pressure arrives from France tomorrow, bringing the threat of pretty severe storms. Tomorrow evening sees the threat south of Brum. Then into Wednesday, it will be more relevant north of the M4. Low probability, high severity if it happens.

What we don't know - what happens after that. The models are really struggling. Could be low pressure sticking around, could be high pressure moving in.

[Puggit]

Biggest storm risk seems to be the SW and South Wales.Should be mid-afternoon onwards.

Enjoy!

[Puggit]

2 major storms at the moment, one smaller one about to hit Devon/Cornwall. The big beast looks to be heading more easterly, but time will tell!

Excuse my rubbish arrows

It's becoming very organised - a long string of storms

Please tell me it's going to rain in Oxford tonight! My neighbour is on holiday and it takes me ages to water her flowers

Keep an eye on the radar, I can't see this dying out before it reaches us - but I've been known to be wrong before!

My guess is more places will get rain than don't. But gaps can and do occur.

Chances of some in east London tonight?

Likely - that bulge (which was/is an MCS) is forecast for your part of the world.

Biblical thunderstorms in Guernsey today, apparently - I say that as I'm not actually there. South of France, 35 degrees and clear as a bell.

That was the MCS mentioned above
