Storms and Convective discussion - June 2023

[Eagle Eye]

No discussion for tomorrow, I let myself off the hook so just the risk map sorry. After the past few days I'm tired. Just below slight risk in the central south area, wouldn't be surprised if we did see an active thunderstorm there though.

Aargh!!!

so angry with myself as i was too tired to chase today as the storms again wasn't moving that fast,i stayed put thinking a development would push further north out of Nott's but only got as far as S Sheffield then exploded further west into Manchester

as for the models and anomalies,...still a long wave trough W/SW of the UK  but maybe retreating west in the ex'd but that would pump more WAA north into the UK

all to play for in the next 2 weeks

lets see what happens,...goodnight all and thanks to another day of mayhem for some but again flat chested turkeys for most,...you win some and you loose some

chins up guys(including me),...plenty of opportunities i am sure

goodnight all

As Carol Kirkwood would say... some absolute "humdingers" as far as your photos/video you have all posted in the past 36 hours... 

I'm jealous (as nothing here on the south coast), but genuinely happy for you lucky lot, and totally in awe!! 

Amazing

Night all

Yes....some brilliant photos and videos of storm cloud development and structure on another amazing day....i saw more of the development today although no direct hit...however there is nothing like the feeling of exitement though when storms are brewing which i am sure we have all had since kids...eager for the next thundery episode now...

Another day, another thunderstorm

As much as I hate hot, sweaty and sultry summer weather, I tend to find it much more bearable when each day ends with a thunderstorm

The past three days have turn out to be quite a notable thundery spell.

Today was my fourth storm in three days!

Let’s hope that we all don’t have to wait too long before the next thundery interlude.

[JR319]

Supposedly the thunderstorm risk returns this weekend? 

[WeatherArc]

Round 2 next week then? 

The earlier 12z run also showing some decent shear around as well, guess this is one to watch over the next few days

GEFS and Euro also have  good support.

 

 

 

 

Looking like we won't have to wait long for the next thundery spell

Saw this on Facebook, rain pouring through the roof a Costco in Trafford park.

@WeatherArcIf this materialises, then we’re really being spoilt here in the Midlands

[Zak M]

Just realised I haven't shared this - my view of the storm over London after 4pm..

[pad199207]

Quite a nice light show here just west of Dublin the last while. Mainly elevated though.

It made it across the sea anyways

KW's Thunderstorm Predictions >>> 12TH JUNE 2023 

Monday with all the potential to be a noteable severe weather day, firstly we see the biggest available deep layer shear out of this pattern thus far 

I'm expectant of the first cells that develop merging into another MCS type scenario akin to the last 2 days but a possible exception and the MCS itself could be quite severe in its own right as I'll discuss in a sec. IF the MCS doesn't use up the majority of the available CAPE + Instability which in its own right is quite remarkable for UK storm setups again will show below, but yes IF there is still enough left and cells can utilise it this is a general zone I wouldn't be surprised getting a storm attempting supercellular characteristics 

As mentioned the MCS type development has every chance to be severe / possibly damaging with large hail and rainfall rates capable of flash flooding 

 

There will also be intense-severe storms around Glasgow and the Great Glen up toward Inverness 

Get these saved in your storm galleries if you like charts to reminisce with 

just your casual 2000 CAPE values ..

 Best of luck for you guys + gals in these zones absolute zilch here hopefully the next plume opportunity gives me better chance

 

Very pleased with how this developed

That'l be those rainfall rates capable of producing flash flooding

Severe conditions focused over Ireland for Tuesday, if any of the Irish contingent that are accustomed to looking at CAPE charts surely 2000 + CAPE is a rare sight over your way? 

Impressive 

Note the significant hail matches on the sounding which goes nicely with this chart 

Galway and a few miles east of there seems a good area to monitor for some of the most severe storms. 

Models are hesitant at making a lot of the instability for southern central England I'm getting a vibe the atmosphere will be a bit too capped there though I do expect the Northwest Highlands will be a secondary sweet spot.

Storm near Weymouth.

Magnificent, a tremendous thunderstorm. One of the best I can recall for years. Continuous thunder, CG lightning.

 

The development of it was something else and thankfully I placed one of my timelapse cameras in the right place

 

My regular timelapse looking NW.

The way rain shafts suddenly drop reminds me of mini microbursts

Took a couple of videos of the storm

Another chase day yesterday with a high risk of storms expected. 

Started off heading down to Tamworth, or just south of there, with the idea that the M42 would provide a good north to south road for me to intercept storms moving westwards if and when they developed. I could see storms on the radar, and they were going to head to my south towards Coventry area but there were also new developments further north heading towards Nottinghamshire. I was torn between whether to stay put, head south or head north. In the end I decided to head north as it looked like storms could possibly hit closer to home.

Joining the M1 at J23A I could see a jet black sky to my north and very soon I was driving into what looked like a strong thunderstorm. Indeed it was, flashes of lightning, torrential rain, 1-2cm hail and all this being slammed against my car by driving winds. All this was in the vicinity of East Midlands Airport. As I knew the storm was travelling westwards I decided to join the A50 and head west in the hope to get ahead of it and get out the car for a bit. I overtook the storm and stopped off at the Derby/Burton services at the A50/A38 junction. Around here there was a brief period of gusty winds and large hail (2cm) as the storm approached but as it moved over the hailstones disappeared and it transitioned to torrential rain but still with some impressive gusts of wind and the rain really was torrential. There were lots of flashes of lightning, but they seemed mainly high based with the thunder not being particularly loud until after the storm was moving away. It is quite possible that the lightning and thunder was being somewhat muted by the intensity of the rain and wind.

After watching the storm pass over I decided to chase it again, but by now it had pushed further west than I had anticipated. Even so I headed down the A50 and, noticing flashes to my south, I came off at Uttoxeter and headed towards Stafford/Stone. Unfortunately I never managed to catch the storm back up enough to overtake it again, I was instead driving just to its back end and was as such seeing lightning ahead of me but heaving to navigate flooded roads. In Stone I ended up stuck in a traffic jam in what I thought was roadworks and was stuck there for a while. In actual fact it was flooding across the site of the roadworks with traffic cones and barriers strewn across the road, floating around in the floodwater. It was quite scary driving through as the floodwaters were deeper than I thought and I was having to avoid floating debris. 

Once through this flooding I could see that a number of tree branches were down and there was further flooding in parts. It was quite obvious to me that a severe thunderstorm had passed through Stone. For some strange reason I carried on trying to chase, this time heading towards Nantwich and Chester. I did eventually catch the rear of the storm up again, and by now it was producing some nice CG's and IC's but I was never going to get properly into it again, and subsequently it began to die out. At somewhere just outside Chester I decided to leave it and head home, stopping at Crewe for a quick McDonalds first.

Ended up getting home about half 10 and just went straight to bed as was working on only 5 hours sleep, hence no update last night. 

A bit of a rest for storm chasing now for a few days, which works well as I have to edit and upload 3 days worth of footage as well as work. I am already looking out for the next opportunity but for now I am quite glad of the upcoming rest 

Edit: Belper itself was hit by a storm yesterday too, which is somewhat of a rarity. I did not get back to Belper though and if I had done, I probably wouldn't have chased the storm as chasing from home is hard due to busy traffic in Belper at that time on the one main road through the town.

Nice account of events.

There was quite a bit of flooding around here too during and just after the storm passed, with many roads under water (saw the pictures on Facebook). One car had to be recovered from floodwater in town.

Thank you.

The rain was absolutely torrential under these things so not surprised by the flooding.

[Sprites]

There's been some large hail around in the recent storms. The N.W. radar hasn't shown hail for the last few weeks.

Looks like there were a few short lived elevated storms that came into the Dorset coast near Portland around 3am. Anyone hear anything?

[ChannelThunder]

Models look encouraging for a Saturday night plume and further pushes of downpours from the south into next week. The Friday just gone looked good for down here at the 5-day stage too though but we ended up getting nothing, so it's JFF at this stage. 

[Paul]

Yesterday's lightning strikes - just the odd 35,000!

[Azazel]

some models still picking up on a weak signal for CS areas today

I'm gonna stick my neck out and say we are going to have the best storm I've ever seen in my life.

12th June 2023, a truly memorable evening in Crewe weather history.
