Sparkiee storm

Brickfielder above & Convective Weather have similar forecasts on today's small potential. http://www.convectiveweather.co.uk/forecast.php?date=2021-07-18 Day 1 Convective Outlook: Sun 18 Jul 2021 Day 1 Convective Outlook VALID 06:00 UTC Sun 18 Jul 2021 - 05:59 UTC Mon 19 Jul 2021 ISSUED 05:16 UTC Sun 18 Jul 2021 ISSUED BY: Dan Upper ridging dominates across the UK/Ireland through Sunday, with a gradual weakening through this forecast period. Strong insolation and resultant diurnal heating will result in deep mixing of the low-levels, and while forecast profiles suggest potential for several hundred J/kg SBCAPE it seems likely that what convective cloud can develop will either be restricted in height by warm noses aloft, or struggle to maintain itself due to the dry mid/upper troposphere. Consequently, despite perhaps numerous attempts at fair-weather convective cloud attempting to gain some height, it may fail to produce many showers (at least for any length of time per individual cell). The main focus where convection may be a little more sustained is along marked convergence zones, such as in central Ireland and through Yorkshire/Lincolnshire, or aided by orographic forcing such as in Wales. The overall lightning risk is very low, but perhaps particular attention is given to central Ireland and the S + W Midlands during the evening hours where some subtle forcing aloft approaching from the west may phase with pre-existing convergence zones to briefly (for a couple of hours) enable convection to grow tall enough to produce an isolated heavy shower / thunderstorm. If this does occur, some local surface water issues could result. During the early hours of Monday, there could be an uptick in elevated convection across East Anglia - although the risk of lightning is considered rather low.

Im not sure but the CZ was created by an Easterly breeze running into a Northerly i think, so if im thinking correctly it would create it this way lol.

Hmmmm? Around about South London, East of Guildford.

More torrential downpours here and more thunder just to the west and East but none overhead. Also im pretty sure this had a little rotation in it, as there were further clouds moving right and closer clouds moving left from what i could see You can sort of see the rotation in the pic, the way it bends round.

Still some good convection here.

Tropical style downpour here with a few decent overhead loud rumbles, didn't see any lightning but the detector shows there was, and got soaked through walking home. Not complaining though its part of the fun and it certainly kept me cool from he mugginess A couple of snaps of the skies after the storm, which looks like a newly forming anvil.

What's this Vortex/Swirl within the frontal band in the South East? Heard of MCV's but I don't think I've ever seen one within a front.

Just like a mini MCS, with the lightning and storms on the East and South East sides and a mass of heavy rain elsewhere.

Only 2 distant but clear rumbles earlier and been heavy to torrential rain since then, a good soaking. But storm still going near Birmingham and near London.

Is that a hook?

Thunder just to the SW from the Stourbridge cell.

That lightning rate is insane, some must be really strong to glitch out the camera like that.

Thanks @Paul, certainly will give them a read as i wasn't on here back then.

Could you point me where to find the thread for this El Gordo bust please?

A couple from the 9z, a mass of rain developing through this evening and overnight, not expecting it to be electrically active, possibly 1 or 2 weak storms within it, but mostly just an area of rain with heavy bursts. That's if it goes the way its showing,

I think in the past 6 years, i have experience 2 overhead MCS's here in the West Midlands, 3/4th July 2015, 23/24th July 2019, and the edge of 2 last year in August. Yeah its common for them to get shifted away to the east but they don't always get shifted especially if they can still affect the western parts of the Mids. Looks okay so far. Not getting hopes up till probably Monday Evening.

Some convective downpours have developed in the SW, don't think these were forecast, al i heard was patchy drizzle.

Think these are the showers/storms that are meant to track NE through the evening. Possible more breaking out. Muggy feeling too.

Some convection getting going now there is decent sunny spells.

Looks like a storm is about to hit here -

Evaporation before reaching the ground.

Either that or someone moving a bin is a common one that sometimes gets misinterpreted as thunder too.

Maybe something firing off?

Is anyone in central London, that can confirm these tiny showers? I thought it was anaprop but they are drifting and anaprop doesn't usually move on radar. Meanwhile France is exploding.

Hopefully that will explode later.
