The warning is there to highlight the risk of thunderstorms, which are outlined to be ‘scattered’ in the warning text. The most recent computer generated forecast doesn’t see any thunderstorms for your location, doesn’t mean you won’t get any. At the same time you may not get any, but if the risk is there and there will be some in the general area, the warning is there to highlight that.

Otherwise they’d be updating the warning area every time a computer forecast comes out... not very practical as a warning system. 

Then the graphics should reflect the risk then as that's the thing people first see. It's poor design perhaps it's my scientific training where I was taught that data must be clearly presented and communicated.

Todays showers are very slow moving some bright echoes but very little lightning being shown on the radar.

The humidity has suddenly gone through the roof here! Plus a few rather large convective rain drops.

LOL Met Office hear my crtiism and change the symbols to reflect the text forecast which is unchanged. It would be funnier if the text forecast had changed to light showers.

Yeah definitely have seen the potential for tomorrow and it does look pretty like what id expect from Estofex, Deep Layer Shear is best placed over Ireland when I looked this morning. Looking forward to seeing Convective Weathers take on it.

A small but intense slow moving 'cell' north of Bradford at the moment. Humidity through the roof and rain was pretty intense (and fun to walk through) but no lightning yet. Could produce one or two strikes  I would have thought.

The sky to my south is black! And the radar seems to confirm this.

There looks to have been a couple of flashes of lightning just south of Llangollen.

The humidity here is horrendous this evening.

 Looks like i’m in a brilliant position for today. Paul on  UKWW has issued a very interesting outlook. Will keep everyone updated. Hopefully I won’t need to throw in the towel early today.

Sure does look like it unfortunately places Like Derby And Yorkshire who really don't need it also look in the firing line

let's hope those areas miss the worst of it

I also look to be in a good spot today and areas to my north. The Peak District could be a focal point this afternoon which is really not good for Whaley Bridge. Early signs are promising, taken about an hour ago. Already feeling humid too.

Not expecting anything but a few heavy showers late on which will probably turn to storms as they head away from here.

Day 1 Convective Outlook

VALID 06:00 UTC Sun 04 Aug 2019 - 05:59 UTC Mon 05 Aug 2019

ISSUED 22:55 UTC Sat 03 Aug 2019

ISSUED BY: Dan

Update: Risk zone modified due to the entire British Isles conveniently being nudged approximately 100 miles north by our old friend, the vertically stacked low. Or something.

Heights will gradually fall through Sunday in advance of the approaching upper low over the Atlantic. A shortwave will slide northeastwards across England and Wales, coinciding with peak diurnal heating, while Ireland becomes subject to the cold pool associated wth the large-scale trough axis swinging northeastwards.

A rather complex and messy picture is likely to evolve, with scope for both elevated and surface-based thunderstorm activity possible. In a broad sense, embedded pockets of elevated convection will be possible on Sunday morning over the Irish Sea / Scotland / W Wales, with other pulses developing over northern England during the afternoon - lightning activity is questionable within this timeframe.

However, provided there is sufficient clearance for surface heating of the warm, moist low-level airmass (dewpoints 15-18C) then up to 1,000 J/kg CAPE will be possible in places, with a risk of scattered showers and thunderstorms developing almost anywhere within the Scotland / England / Wales SLGT and MDT zones - particularly late afternoon and into the evening hours. 

The best multi-model agreement on where coverage of thunderstorms may be greater exists over the north Midlands and parts of northern England, and so a tentative MDT has been introduced. The primary hazards will be hail up to 2.0cm in diameter and localised flash flooding, especially given how sensitive the already saturated ground is.

Additional elevated convection (showery rain) may develop over East Anglia / SE England during the evening hours before moving offshore.

Other additional scattered showers and thunderstorms are likely to affect central, western and northern Ireland - especially during the afternoon and early evening, before probably merging into a more dynamic area of showery rain as they exit eastwards to the Irish Sea. Main hazards here will be localised surface water flooding, and perhaps an isolated tornado.

I do see where you’re coming from but I feel they’re a bit damned if they do, damned if they don’t. If they had thunderstorm graphics for your location for the duration of the warning it would 100% be wrong. 

In my opinion I feel they’ve got the best of both worlds with the warning, a general warning to highlight the risk, then you’ve got location specific graphics to show what to expect in that exact location hour by hour.

Best of luck for today anyway, I have no chance of anything really so hopefully some others get something decent... Do feel for Whaley Bridge though...

Fairly benign muggy weather down here in St Issey. Front went through this morning and it's now partially cloudy.

Looking back at Whaley, it's a wet outlook. I have many friends there and three of my children went to the primary school. Ive got pics of the family stood on the walkway directly over the failed area, one could never imagine that the current situation would unfold.

Thursday Friday looks wet and the latter is the day we head back north.
