Looks like we got ignition in the last 30 mins showers popping up! LET THEM GROW INTO MONSTERS XD

The Watnall 00z ascent is probably representative for most central and eastern areas of England and it shows tops readily to 24-26000ft with 11C T and between 3-5C Td.

The Extra prediction for Doncaster shows similar for 12Z but with tops becoming more limited by 18Z

For this area all the upper winds are now n of west, up to 18000ft, yesterday the lowers winds were thus but from 10-18000ft they were still mostly southerly.

I suspect this was in part responsible for the semi permanent radar echo SE of here through the night with some places getting almost 25mm.

North & East Yorkshire are a good bet today, intense cells developing on the radar although the cell near Darlington has lost some energy over the last 20 mins after showing 50-60mm/hr PPN falls.

Lincs again could have some impressive convective developments, perhaps further funnel clouds could materialise in a few locations? Keep a camera handy folks!

Well the Cardiff cell did decay a little bit into something more linear. A decent gust front preceded 15 minutes of very heavy rain and a few hailstones and a temperature drop from 9.8C to 7.5C.

Sunny again now with new cbs out to the west.

[Evening thunder]

Some nice showers getting going around me, but they are all passing to my north and south with no more than a few spots and nothing coming this way on radar. Almost as predictable as clockwork really.

And anything that does head this way invariably dies, the only hope on the radar just did the same, unlike the showers going elsewhere.

Popcorn cells breaking out ahead of the precip that affected Nottingham, heading towards the northern home counties and London

[chionomaniac]

First hail shower of the day!

[Lewis]

Few cells firing up.

Me and Dell Trott are now positioned on the Humber, all ready. Got a large cell to the east of us that'll clip us and move just off shore, and a nice potent cell firing to the NW of us, which is heading for us.

Lovely cloud formations, got the weather station and satellite setup on the car roof, currently recording a temp of 10.3c with a dew of 7c.

Temperature was recording 15.4c with a dew of 9c 30 mins ago, so quite a drop.

Wind slight to moderate, bearing WNW.

Waiting on the boys from the North East to get down here, and we are going to do some live streams, will post links a little later.

Regards

A few splashes of rain here, but the convection doesn't seem as spectacular as yesterday, as by this time there was a narrow line of torrential hail and rain in South Northumberland and Newastle. Having said that, these pop up showers might support the development of thundery showers later, whereas the rain yesterday died out, and the lack of sunshine meant there was a lack of convection later in the day in the NE.

I'm willing to give today a go but with the luck Bristol has I'm not holding my breath.

Have hope. The number of times I've sat in Yatton and read reports of thunder in Bristol and nothing here, then last week the role reversed. Fingers crossed.

[Hodgheg]

Stuff trying to go up here but i have a feeling that everything will be just to the East of me today

[NO LONGER POSTING]

so much ground for those showers to cover before they hit the london area..lets hope they can tap into some energy

Well the showers are moving more from NW than the W and i usually find that helps increase chances of Bristol area getting hit by the showers. Problem is they dont develop enough to be that stormy and the fact Wales is lacking CAPE/Li isnt inspiring me.

However showers recently popping up out of nowhere in Wales looking at the radar... Will have to wait and see if they keep building up.

[legritter]

had a good 10 min shower at 11 15am ,small hail and gusty winds  .at the moment it looks like wales will NICK our lot . but hopefully something good for late afternoon .some cells now coming into west wales ,if you dont need them send them to bristol and somerset ,cheers legritter

[Lewis]

i can guarantee those showers over dumfries and galloway heading for me will die over the irish sea, they always do.

[Evening thunder]

Just heard 2 rumbles of thunder from a cell passing several miles to my south.

Edit: 3 now, am outside listening.

Sferics detected about 10 miles to North of here....so frustrating! Good sign though.

Small shower about to hit here, not looking particularly interesting though.

[Kain]

Just started hailing here...never seen so much hail as I have the last few days.

[Wet'n'Dry]

Sferics detected about 10 miles to North of here....so frustrating!

I'm 10 miles to your North Harry and it's pretty quite here !!

[I remember Atlantic 252]

Anvil to my NW, hope not crappy old pure rain though, want hail/thunder and lightning
