So watching the current NW radar (and Sat24) - where are the cells that we're expecting to drift north to the UK at the moment? It's raining & muggy down here on the Hampshire coast but it doesn't feel like anything's gonna happen (please prove me wrong weather gods!)

Any later dont exist currently. If they fire, they'll go from nothing to strobe light effect in about 20minutes. 

Satellite Imagery shows we are now coming into the nowcast time frame with something of clearance coming into the south, effective the back of the warm front (we have sun in Bmth). Eyes down, radar's at the ready!

Definitely signs of a clearance here with the sun starting to come through the cloud. Feels humid.

DP here has jumped to 16C, highest of the year. Slightly irreverent for us though as coastal areas will be more interested in the Elevated Plume.

Altostratus undulatus, pretty sure they've not changed the name

I think they are now collectively known as Asperatus but may be wrong...

Even though we still have hours to go I think the time is right to get excited, every passing hour now will show signs of development leading up to the main event (hopefully!)

Do you know the reason behind the name change?

Edit: You are right, according to Google the name was changed back in 2009

Just been out. No thunder in the annoying odd drop of rain with some heavier drops that is happening. Why do i know it's not gonna thunder?  'Cos the clouds don't look the right shade of grey/blue. It doesn't smell stormy or rainy.

I didn't think it was any more humid then this morning - i am still wearing a hoodie and glad of it. 

Very slight breeze.

Have the met office shifted the warning further west?

No, warning box on their website is the same as yesterday i.e. south western tip curve's around Portland.

Gone a bit murky but there’s a real calmness and quietness to the air here

That is not a bad thing. Before every storm, there’s always a calm!

Wasn't Asperatus designated as a new cloud name during a campaign by the Cloud Appreciation Society, rather than a change of cloud name? Whatever the nomenclature technicalities it is a beautiful cloudscape to have - we often get it over our valley before a storm (or someone else's storm).

It's usually a sign a storm is coming. There's some around my area as well. It's also very still here as well.

Saw some of the most awesome undulatus (a variety of, anyway) last year in Soller, Majorca. It looked like a cloud sausage - and that afternoon in Deia we had a huge rainstorm with embedded thunder.

It doesn’t mark an absolute certainty for lightning, but it is a very good precursor for stormy weather

A little off topic but does anyone know if we actually send up weather balloons in this country? I was surprised to learn we have doppler radar the other day when reading up on the 2012 oxfordshire supercell (a couple stations were used to track this storm), so i'm interested to know if there's anywhere to find real soundings.

    Dubai Floods: Another Warning Sign for Desert Regions?

    The flooding in the Middle East desert city of Dubai earlier in the week followed record-breaking rainfall. It doesn't rain very often here like other desert areas, but like the deadly floods in Libya last year showed, these rain events are likely becoming more extreme due to global warming.
