You'd be safe here in Doncaster!

Been watching big showers all afternoon both to the N and the S - but no precipitation at all has reached me...

T'other half reported a significant hail shower just N of Doncaster at around lunchtime.

Think that one went white on the radar.

Their a nice looking cell handing past me north of haywards heath. No thunder or lighting yet. But look like a scene from twister carm before the storm!

A nice hook-echo on the 1705 radar return north of Buxton. I was looking at the cell around the same time but nothing evident seen, other than a gust-front prior.

Some very photogenic CBs over Leicester this evening. These pictures were taken about 15 minutes apart (the one with the big anvil first) at around 1700 looking North towards Loughborough.

Short heavy shower over fleet. Several rumbles of thunder, one observed lightening flash. Some hail.

[Lightning Hunter]

I sat on Portsdown Hill, nr Portsmouth this afternoon after work. Missed the earlier thunder, but caught some really photogenic Cbs

I filled a memory card with images for the first time in about 3 years! Had a good view of the Southampton cell as the Sun lowered too.

No thunder witnessed at all though.

Showers forming in lines again, though oriented more NW-SE than yesterday's W-E. I wish I knew why lines formed!

I think it's 'roll-type convection', when the flow is linear (no directional shear). I found the attached graphic while wondering the same thing myself, but would assume in today's case it was somewhat more enhanced by instability than just cloud streets.

Well what a day,cbs in pretty much every direction from 11am,thunder heard from cell over north shropshire at 10.30 things went quiet then until a meaty cell with fantastic structure skirted telford at 14.30,strong cc and torrential rain,and then came the star of the show a unexpected hail storm at shawbury around 1600,tje biggest most intense hail i have ever seen-malteeser sized! Then some sunset lit anvils to end the day...

12/04/2012 Looking at Ukww Plotter Cape is showing over Southern UK and the East coast of Ireland near the border from about midday extending to Northern England in the afternoon. Estofex has a slight risk shown for today. STV local forecast for Scotland has also forecast heavy showers with possible thunder. Not a forecast just a summary of information available.

Lots of stratus around this morning. Views will be obscured if it doesn't at least lift before stuff gets going.

EDIT - already see it shooting up to the W & NW. There seems to be a train of tcu to the N as well.

A bit messy around here too atm. Quite nice when the sun comes out. A more northerly flow than yesterday so anything decent usually skirts either side of me when its like that.

[skanky]

Already looking like following yesterday's trend. Got one to the W and one to the N, but no really clear view of either.
Radar shows the one over the W Peaks clearly (looks like hail on Kinder), but the one to the N over Bradford looks messier on radar - and there's no clear anvil from here either.

There's now a few bits of convection starting to bubble up here and there so hopefully....

[skanky]

Looks like the one to the N of here is collapsing.

[Ed.]

Unexpected thundery shower atm, seemed to come from nowhere - certainly going to be a day of hit and miss! could get quite interesting further S and E as the day progresses.Good-luck peeps.

Chunky fella heading into Birmingham right now...
EDIT: Accompanied by a few sferics now too...

The one over the Hope Valley looks to be lessening on radar. The anvil and main part are too close to see if the structure's messier, but it still looks impressive.
It looks like though (and radar is suggesting similar) that there's another one growing on the back end. It's fascinating to watch, though killing my productivity this morning.

Oh and there's a sparrowhawk flying around in front of it all - though I can't get a good shot of that.

The good thing about being a writer is that I'm not bound to a desk so can take the time to go out with the camera when something interesting happens, like a little bit of convection. The bad thing about being a writer is that I've justified pretty much consigning this week to the scrap pile and am going to have to work over the whole weekend to catch up.

Sky went black as black and i was expecting a few bangs. Alas, all we recieved was 30 minutes of steady rain with a few heavier bursts and some soft hail mixed in. Quite dissapointing really as it looked a cracker on it's approach!

[JOKE_SNOW]

A couple of cold-core funnels (scud) trying to form on the inflow of the convergence zone here, however obviously being scud they amounted to nothing. Currently moderate rain with the other side of the valley close to Edale still in sunlight.
