Timelapse of the mad cloud movements as the East Leeds storm came over us- this is looking east and was a rush job when I got in so sorry for the rain on the window! There's some mad updrafts at the very start- its a free app so resolution is a bit limited- no HD here I'm afraid but hope you enjoy anyway!

That's excellent, amazing movement there.
Nothing here today.

Out chasing having problems with my net could someone be kind enough and post me an image of hu9 4rx
Can't access my netweather extra. Thanks
Sorry just seen your post, here it is...
Good luck!

Very frequent lightning from that storm just leaving the north of France now!
Precipitation is losing intensity unfortunately, but hopefully it will still be active enough for people in E Kent to see something.
Much brighter here now with some spells of sunshine, feeling much warmer too, and some convection.
For my location I'm worried about the light showers approaching from the south, I think they will inhibit any decent convection.
Some decent cells around Lincolnshire now, but no sferics yet.
-
That storm wasn't that great by the time it reached Nottingham, but I did observe two bits of lightning and some thunder, and got some lightning on a still photo so I'm still pretty pleased.
-
Decent structure on this approaching Nottingham...
Finally a good storm coming for Nottingham?
-
Get the match on huge storm ITV! Match suspended. Crazy.
-
The Extra one Paul.
Someone else in the convective discussion also reported the same problem.
Just noticed it's working again now, just missing the strikes from time it wasn't updating I think.
-
Not sure if you aware, but the ATD lightning detector on Netweather Extra is stuck at 15:20.
Hope someone can give it a kick and get it going again soon, as it's so useful on days like today.
Thanks.
-
Is anoyne else having issues with ATD lightning detector? Mine hasnt updated since 15:20
Same here, still stuck at 15:20. Hope it starts working again soon.
Got another fairly heavy shower here now, but again doesn't seem thundery.
After this I've already got my eye on the next one currently over Birmingham, but again it doesn't look too exciting yet.
Meanwhile another big shower is heading towards County Durham and Tyneside, hopefully that will hold its intensity until it reaches the highly populated areas up there.
-
same old, same old in the West Midlands...we breed them, the east gets them......getting to sound like an old broken record....lol.......line after line of showers fire up and as soon as they pass the west midlands they explode into life and start flashing & banging
That seems to have happened a lot here too. Showers seem to explode into life about 10 miles after they pass through Nottingham then slam areas north east of here with thunderstorms. Feel like that's happened at least 5 times this year already, including today.
Probably going to happen with the next shower approaching here now, it's very black to the south again.
At least I'm getting heavy showers here today though, which is better than nothing.
-
Definitely heard a distant rumble about a minute ago
Good, about 20 minutes ago I told my Gran in Jarrow to expect a thunderstorm in half an hour.
Wish I was still living in Hebburn just for today.
Another shower approaching Nottingham on the radar, but nothing too interesting.
-
Just had a short lived but very heavy shower here with gusty winds. No lightning or thunder though.
There were a couple of rumbles during the night at about 2am during the heavy rain which was a nice surprise.
Got some decent pics as that last shower approached, I will upload soon.
-
Good luck those heading out chasing tomorrow. I think I'll just sit here in Nottingham and hope for something to hit.
Car isn't too good at the moment so I don't want to risk making things worse.
Here's the ESTOFEX forecast which Dazmaster mentioned earlier...
DISCUSSION... UK, Scotland ...
Behind an E/NE-ward moving occlusion, a maritime air mass overspreads most of UK from SW to NE. With cold mid-level temperatures atop and placed beneath the left exit region of a strong 45 m/s 500 hPa streak, scattered deep convection is anticipated mainly between 9 and 21 UTC. Overlap of roughly 500 J/kg MLCAPE and 15-25 m/s DLS (increasing from NW to SE), a few well organized multicell events are forecast. Isolated large hail and strong to isolated severe wind gusts accompany strongest convection. Despite a somewhat marginal directional shear component in the lowest 1 to 2 km AGL, forecast 150 m^2/s^2 SRH-1 and any deviant storm motion provide adequate helicity for an isolated tornado event. Storms gradually diminish during the first night hours (also in line with faint warming of the mid-levels).

Just looked at some river levels, and already the Wey at Passfield Mill is about to set a new height record.

Sorry to see some on here having problems with the floods.
-
Already around 70mm looks to have fallen in some places with more still to come.
BBC weather latest tweet...
"Numerous roads already flooded in SE England. Conditions expected to worsen in the Capital as the heavy rain pours through rush hour"
Looks like this event will be every bit as bad as expected and possibly worse.
-
Big shower parked over the eastern side of York now, not moving anywhere and intensifying.
Looks like it's also over my girlfriends village where there was flooding from yesterdays downpours.
-
Showers are very slow moving on the radar, some parts are stationary near the Pennines.
If these showers form a little further south towards York then there could be more localised flooding in that area after yesterdays deluge.
It looks like river levels peaked this morning on the Ouse, and it didn't burst it's banks.
More slow moving downpours in the same area today and it might just flood the riverside area in York.

No sign of sferics yet...

As Supacell has said, chances for storms look a bit limited, but wind convergence looks good and high res NNM charts show showers developing in a similar area to today...
I would like to be able to understand the skew-t charts but still cannot grasp them, if there is no cap to limit the cloud tops then I think storms could develop in similar areas to today with the help of convergence, but I'm not really sure about possible capping and upper temps etc.
I have done a little prediction below, don't take it too seriously, just done it mainly because I'm bored rather than having vast knowledge!
Red area
I would expect showers to get going fairly early in these areas, by around 11am, starting towards the north of the area and extending further south to cover most of the red area by 1-2pm.
Possibly less organised than today's impressive line through Yorkshire, and moving in more of an easterly direction than today's storms which moved south east. Lightning strikes will likely be more isolated and fewer than today's, and more likely in the southern half of the red area. Showers continuing until evening but any lightning activity fading by around 6-7pm.
Orange area
High res charts break out some showers later in the afternoon in this area, and there's some good wind convergence. Cape/Li values improve slightly in this area as the afternoon goes on too. I would guess showers won't get going until around 3pm in this area, and with less intensity than the red area, with only a small chance of the odd weak t-storm from about 4-8pm.
That's my novice effort for Sunday. Let's see what happens!
-
christ Mark! landed on ya feet there.she must be loaded lol.
Haha Peter, I wish!
This relationship has cost me a fortune, leaving my job, moving down here and being jobless for 10 months.
To add to all that my car cost £405 to repair today, so I feel more like I've landed on another part of my body!
Anyway back on topic, looks like the same area could be in for more tomorrow, but maybe the risk extending a little further south according to the charts, so I'm hoping for something down here tomorrow.
-
Wish I had been at my girlfriends house today in Warthill near York.
Her brother has put some pics on facebook...
Looks like more on the way too!
-
I would say the best chance of any storms tomorrow would be in a line from around Glasgow to Hull in the afternoon, and if the sun can get to work then the chances may be fairly good. I would say areas just NW of the Humber for the best of all. Of course, the best of all may just be a few heavy showers but worth keeping an eye on anyhow
As Muffelchen said very good prediction by Supacell yesterday ^^^
Looks like tomorrow the risk is a bit further south, hopefully nearer to Nottingham. Any chance you could predict a line of storms from Merseyside, through Nottingham to the Wash Supacell?
Back to today and still following the radar, looks like rainfall totals of up to 50mm so far in some spots, and 300+ lightning strikes mainly in N Yorkshire.
-
Surprised it's so quiet....the NE is looking great at the moment...is everyone asleep or abroad??
Yeah I've been watching that, looks amazing just north of York with lots of strikes and torrential rain.
There could be some really high rainfall totals too looking at the movement of that very intense line of rain.
Wish I was at my girlfriends house 10 miles east of York, if I'd known this was going to happen we could have had a weekend there!
-
I like the look of what's approaching here from the South West.
Showers intensified a lot on radar in the last 10 mins.
Might finally get a close storm in Nottingham.
Looks like it might pass just to my south this time, but closer than the last one which passed to the north.
-
Thunder heard in Nottingham, finally! Loudest thunder I've heard since lasy years USA stormchase.
Still wasn't very loud though, and I can't see any lightning. I think the core of the storm is out of view to my north.
Thank You All...
in Storm Chase USA

I wasn't able to go this year, but I just wanted to say thanks and well done to everyone who shared photos and reports with us back in the UK, there were some amazing photos.
Can't wait until I can get out there again hopefully within the next two years.
