Heavy rain could bring a few lightning strikes?

[weatherobsuk]

Already some early strikes between Manchester city center & Preston at 10:30am which bodes well as it shows the instability is there from solar heating.

[Coops241180]

Skys looking interesting. 

Heavy rains arrive here now

[Coops241180]

 and this is tracking SW -> NE so hoping for some action mid afternoon perhaps with the sunshine between the current downpour and that warming things up a bit

Sun is about to come out now so hoping I might see something later on.

[Allseasons-Si]

Just had a gusty hail shower here with thunder to my SW.

[matty40s]

That's it, back edge gone, now lets build some action!!

Manchester

[ThomasD27]

The cell W of snaith/ SW of selby just produced some lovely lightning and a nice rumble of thunder- looked forked but didnt touch the ground?

[ChezWeather]

Cell north of Doncaster just exploded into life

[Rufus Butterfield]

Big cb to my north 

[CoventryWeather]

A few webcams around the storm near Selby showed some decent sized hail - hard to tell on cameras though. Any reports from the area? 

[alexisj9]

Still raining here, hope it clears soon, got stuff to do.

'There's enough blue in the sky to make a sailor a pair of trousers'

as the saying goes

Heavy cell` s approaching from the SW .... a chance

I live 10 miles south, just had some tiny little pellets mixed in with the rain although i'm south of the crazy cell. Wouldn't surprise me if there was some large hail to the north- it's exploded on radar and has some really nice structure from over here

[Metwatch]

Starting to see some convection now as daytime heating kicks in. 12.5°C and 81% humidity, so a lot of moisture lower down. 

[Metwatch]

Nice little heavy shower lasting no more than a minute now, pretty big drops and got heavier just as I was recording. 

[Arnie Pie]

Back end of a potent little cell which has just swept over Brum. some small hail

Edit; A few problems with the stream atm .. shutting it down for a while

Got my eye on this, may form into something better if it gets its act together

[Polar Maritime]

Squall line sweeping through here, gusts touching 60mph and heavy rain atm.

Today could be a day for mini-Supercells and/or an isolated tornado is possible. Quoting Cameron Nixon;

"author’s rule of thumb is that if your hodograph features a deep layer of 0–1-km storm-relative inflow weaker than 25 kt, you’re probably dealing with mini-supercells!"

Here's my old explanation of what everything is from an old event. Note that when I said straight for the deep-layer shearing I meant diagonal. You want horizontal (ish) deep-layer shearing for Supercells. Note that it has some links to the event that don't apply here.

Most Storms appear to be high precipitation mode according to the soundings and that could make for some quite good dark moody shots but maybe not for structural shots of an updraft.

A couple taken from Wales and southern England/the Midlands.

Most of these appear to be generally more multi-cell favourable with low-level shearing and streamwise vorticity characteristics suggesting an isolated tornado is still possible.

Very close to the storms to my north but no thunder heard.

Facing south from the Coventry Airport webcam, beautiful structure!
