1&1/2 inches of rain ️ garden loving it filled up water butts too... hopefully helped with fires on moors too... 

[ChezWeather]

Apocalyptic sky to the SW, no lightning unfortunately just heavy rain 

[cheese]

Very dark skies to the SW but looks like plain old rain, no T&L. 

[WillinGlossop]

Just tapering off and just shy of 2 inches of rain.... lovely jubbly 

[Norfolk Sheep]

That rain in London has barely moved, must be a decent total out of that in the Harrow/Edgeware areas.  

[cheese]

Well that shower produced a grand total of 0.3mm, lol. The ground will be back to its usual parched self tomorrow.

[Supacell]

Finally some rain in Belper after 35 dry days, that is 5 weeks with no rain...amazing stuff .

I went out for a drive up to Matlock and around abouts this evening. It went almost dusk like at 7:45pm and then an hour of on and off torrential rain. No TL unfortunately but plenty of rain and some large puddles on the road.

Back to hot sunshine for the next 2 days.

35 days dry is 5 weeks not 7!

[shaky]

No rain what so ever in leicester!!i actually cant remember the last we had rain lol!!its been that long!!humid as heck right now!!

[Weather-history]

Drought broke last evening

 

[The PIT]

Nothing much here just 4.4mm still thats the dry spell broken.

Day 1 Convective Outlook

VALID 06:00 UTC Sat 14 Jul 2018 - 05:59 UTC Sun 15 Jul 2018

ISSUED 05:17 UTC Sat 14 Jul 2018

ISSUED BY: Chris

A ridge of high pressure will continue to build across the British Isles bringing largely fine, dry and very warm conditions in the south. 

However, a small amount of instability will linger across eastern parts of England into the afternoon (CAPE up to 500 J/kg), and may be enough to help generate a few isolated heavy showers. Lightning is considered only a very small risk <10%, however cannot be ruled out in any heavier showers. 

 

Shear remains weak, and any isolated showers that develop will be slow-moving, however rather limited in terms of updraft life-cycle. Showers will pulse and generally weaken quite quickly. Very localised heavy rain will be the largest threat.

Day 1 Convective Outlook

Atlantic upper trough slowly advances towards the British Isles during Monday, while a weakening surface cold front nudges eastwards across England and Wales. Strong diurnal heating ahead of the cold front will encourage the front to turn increasingly convective in nature, in an environment of 500-800 J/kg CAPE by the afternoon. Showers will develop in a rather sporadic fashion along the front (from SW England through the Midlands / E Wales to NE England) as it continues to move eastwards, some deep enough to potentially produce some lightning - but difficult to pinpoint specific areas where this is more likely than others. Have issued a low-end SLGT (ideally considered lower than 30%) to better highlight the corridor where some sporadic lightning may occur - though even here many areas may remain lightning-free.

Farther east, strong diurnal heating will result in sea breeze convergence and the development of a slack area of low pressure / surface troughing over eastern coastal counties of England. While inland dewpoints will likely mix out (into single figure Celsius in places), moisture pooling near sea breeze convergence could locally enhance dewpoints to 15-18C. If this occurs sufficiently, some 500-800 J/kg CAPE may be available which combined with breeze convergence could trigger a few (rather high-based) heavy showers during the afternoon and early evening. Forecast profiles exhibit quite dry mid/upper levels, raising some questions as to how deep convection may be able to grow and hence uncertainty over whether much lightning will occur. Main interest would be Norfolk and north Suffolk, then moving offshore.

Indeed, 3 rumbles of thunder and a serious amount of rain, this is more rain than we have had in at least 2 months. 

[Cambridgeshire Weather]

Don't need to get excited, doubt this work be anything more than a few rumbles of thunder in the south west.

[Another Kent clipper]

@Neglectedchicken you're just trying to reverse jinx it by playing down.  It won't work cos it knows. 

But I have to say it has been awfully humid in Manchester

I think if we all pretend that we dont want any rain or thunder then we may get some!

 

The amount of times ive shouted at the sky "IS THAT ALL YOU GOT!?" 

[davehsug]

Supposedly prime position here, but no obvious signs of anything. Hazy sunshine and plenty of cloud, but no great height to convection and a little floccus but no alt cas I've noticed.

@Ed Stone

cell popped up near you

i must say it is stifling out there today and feels like things could go bang later

who will be right?

i am watching with interest

Sferic mid west Wales.

Looks like something is building to my North
