Convective/storm Discussion Thurs 23>>>>>>>>>

[Harry]

For those who missed out on storm action recently, check out this video of a Cambridge funnel - quite impressive!

Note - contains some swearing!

[SnowJoke]

That was cool, nice little storm just rattled through. dropped some heavy rain and a few close overhead ic's. Only 1 sec gap between flashes and nice crisp air splitting thunder. 2nd storm today so alls good

Nice video, and I can't be the only one who loves it when you can hear how excited the people behind the lens are.

[Noctilucid]

Harry look to your W/NW, beautiful storm to my S/SE, massive anvil shield with a widespread display of mamattus developing overhead.

Thunder continuing to south and S.E. from slow moving Cb (Redhill direction).

I can confirm that tax-payers money has been invested wisely and the Burgess Hill Stormshield is holding well

[A.J]

certainly some nice cells developing rapidly now in salops and staffs, with a pronounced squall line orientated west to east heading SSE towards stafford and birmingham, with further discrete cells firing up further south heading eastwards towards Central/South Birmingham...The 1000hpa wind vectors are showing an area of convergence setting up to the NW of birmingham, with WNW meeting WSW lower level winds....Interesting.....

[snow raven]

Distant rumbles of thunder again in Bexleyheath. Can see an anvil to my South, so possibly came from that?

[Paul Sherman]

The Mammatus over London at present is Udderly Outrageous

...I guess the cell looks a bit beefy?

[k66yla]

more thunder here now and lightning to my north.

[A.J]

Oooh, Salisbury Plain/North Hants is looking good for initiation!....1000 J/Kg CAPE, local LI of -4C and lapse rates of 28C....anything kicking off there will have London's name written all over it!

Without exception, that is the most STUNNING display of mammatus I have EVER seen!

I have LOADS of pics of it - bear with me while I upload!!!

The storm is right above me now, lots of lightning and thunder and torrential rain

[Noctilucid]

Yeah its right overhead, whats amazing is how widespread it is, covering one quarter of the sky and spreading. If only the sun was setting now it would be an absolutely fantastic photo opportunity!

bear with me while I upload!!!

You might want to run before it eats you.

[Harry]

Seriously, you have to see it to believe just how spectacular they are!! They do cover almost half of the sky!!!

Enjoy - sorry if the quality is bad!

[Thundery wintry showers]

Back now - late luch and then distracted by other matters.

Fairly impressive storm passed to the SE of us - first thunder heard at 14:27, heavy rain and some bright lightning flashes observed (from my vantage point I was unable to see whether they were CG or IC. A lot of turbulent clouds still hanging around and the occasional faint rumble heard still.

I think they were IC- or at least the ones I saw were, because they didn't reach the ground.

I assumed that would be it for today in Norwich but there is another cluster of heavy showers moving into the far west of East Anglia now, which could be interesting if they keep their intensity.

[Buckster76]

wow to the Mamma

we've a distinct "line" at the edge of the storms

and there are actually Mamma fingers hanging over the edge of the line !! amazing - just out with the camera

[Neilsouth]

Intense downpour , Large Bangs and hail!!

WOOOOOOOO

[Harry]

Apparently there was a torrential thunderstorm in Sevenoaks earlier - torrential rain, large hail, and impressive thunder and lightning!!

Still - my day has been made up by that mamma display

Great photos Harry, what a treat! To think that's the sort of thing that probably 99% of Londoners won't have noticed, because people almost never seem to look up!

[Paul R]

Yello. Had a decent storm here this afternoon. The rain was absolutely torrential. I couldn't get near a computer at the time as I was in work but was watching the lightning (first time I've seen an anvil crawler in years). Surprised we didn't lose power in work if I'm completely honest. All disappeared east now but nice end to the week nonetheless.

Yes, could be an interesting dessert after the main course earlier!

Having added some overlays on the NW radar, there seem to be ideal conditions - lapse rates, CAPE and LI all good, not much inhibition either. Only negative is lack of wind shear.
