Storms and Convective discussion - 16th June 2021 onwards

[SqueakheartLW]

Could I really get 4 thunderstorms this weekend alone?

After that sudden cell development yesterday evening just for me in Scunthorpe could it get even better today

It sure did

Storm 1 today did a similar thing to the one yesterday evening when it blew up just near us again to give us a storm, although not as big as yesterday evening's one

Storm 2 was probably the most drab of them all with just 2 rumbles of thunder and that was my lot but I have been spoilt already with 3 storms so far over the weekend

However storm 4 of the weekend looks like it could be the biggest of the lot

This great mass of storms is heading north right now and isn't that far from me now and is still producing lightning flashes on the lightning detector

I know a very unfair distribution of storms but if you are in Lincolnshire right now or areas due north of there like me in Scunthorpe, North Lincolnshire it looks like game on soon and just as I finish typing this I can now hear the first distant rumbles of thunder from that nice line of showers and see the dark skies to my south now

[Had Worse]

Had an isolated loud clap of thunder about 10 minutes ago. It came as I was turning cars around for tomorrow's commute.

Lightning maps didn't record it.

[SqueakheartLW]

Paying particular attention to this circled area that has developed within the main shower band. Is this one of those lucky blow up cells that appears just before it reaches me again, I hope so

[Had Worse]

Not familiar with blow up cells.... dolls.....thats something I am aware of.lol

[SqueakheartLW]

Got to feel for those thunderstorm fans who are not in the Lincolnshire area right now. We seem to be the only area in the UK with any storms right now

Just about to hit here right now

[cbish8]

So remember when I said that was it for Nottingham today 

One rumble and absolutely biblical rain

[TJS1998Tom]

Looks like cooling temperatures is coming into play, was suggested that storms will occur later tonight for Yorkshire, guessing it'll be this lot

[SqueakheartLW]

Is anyone near this development in the south. Looks like it has potential to throw up a nice thundery surprise for some

[Hurricane Andrew]

2 thunderstorms in 2 days more rain from this one this evening then yesterdays one cant complain lincolnshire storm capital of uk seems like it

[Andy Bown]

Torrential rain in Warminster but it isn’t remotely thundery. Not one single sferic ever since it began forming in Dorset/Somerset 5 hours ago.

The video that appears when you click next is quite funny to. That poodle is having non of it.

Caught it on my timelapse for today at 3.10

 

Something interesting happens in the clouds at 1.37

Your timelapse videos are amazing WH. They really show the beauty and dynamics of clouds within these weather systems that you wouldn't always see in 'real time', particularly the different directions of wind flow playing out around these heavy showers/storms...

Annnd this was the storm when it reached Spurn Point......

Cheers Glenn

Here is a compilation of thunder and lightning from the storms yesterday,...enjoy

Oh and i even saw an owl,...cool.

Here is today's snippets,i will edit the vids soon...

a couple of Cg's from two deferent storms that actually turned out better than i thought

 

and a decent cloudburst.

Tonight the jet stream comes into action with a Rosby wave trough over the UK. Looks like Northern France, the channel and even some parts of the southeast are in for some very gusty winds for this time of year.

 Since this will be a developing low then there is always an opportunity for convective activity especially near the core of the low. Jetstreak exit dynamics will drive the low and we should expect heavy rain for many parts.

Forecast SkewTs show the tropopause being pulled down so cloud tops will be limited and timing means surface based convection only starts once the system is in the South East of England in the early hours.

 

 

 

Although the tropopause is pulled down and the front will be back bent it is the wrong time of year for sting jets (low not deep enough either).

Main risk gusty winds and localized flooding.

 

 

Wednesday brings another possible day of storms with low level wind convergence likely to trigger storms. Substantial instability in some places mainly in the central and western areas. Winds are weak so no this will limit storm severity.

 

Moisture all the up so convection might be messy with multiple storms hitting some areas. Highest risk is localized flooding.

Unsure if this was posted yesterday

I went out chasing yesterday and have quite a bit of footage. I would try and give a run down but so much was happening that I can't actually remember all of it! I started by heading west to intercept storms moving north towards Ashbourne, but this would prove a bad decision. Although I was able to see the storm and catch some thunder and lightning along with quite gusty winds, the energy was obviously more to the east and I ended up backtracking east again towards Matlock and then Alfreton. Throughout the journey there were pulses of torrential rain and occasional flashes of lightning.

By the time I reached Alfreton the storms had moved away northwards and so I spent the next hour chasing them up the M1. I managed to catch them up near to Sheffield and they were producing torrential rain but only a few flashes of lightning. There could have been more thunder, but in a car driving on a motorway I was unable to hear. 

By this time there was a line of storms developing to the south and moving northwards through the East Midlands and into Lincolnshire. I had been lured all the way up to the M62 and so decided to head east and then south down the A1 with the aim of heading for Lincoln. On the way I was distracted by a small storm which had a nice wall cloud on it, but it wasn't producing much lightning from what I could see and so I continued the journey south.

As I reached Lincoln there was a very impressive looking storm moving in. The skies were dark with a gust front moving quickly towards me and occasional flashes of lightning. I decided I wanted to be ahead of it, so as to not get caught in the rain, and so I headed north up the A15 with the storm over me, stopping occasionally to observe for a brief time. I saw some nice IC's as I was driving. Eventually I had to give up and let the line of storms move over, and this happened near to Scunthorpe. As it passed it produced an occasional flash of lightning and absolutely torrential rain.

Overall there were lots of torrential downpours and thunderstorms, but it was more rain than thunder and lightning that I saw. This was to be expected, CAPE was not particularly high yesterday but moisture was. I did see some decent lightning and hear some cracks of thunder, plus some of the cloud structures were very impressive. A good chase day and a good weekend thundery showers and storms. I have a lot of footage to edit.

Let's hope you're right about that sting jet thing, don't want one near me ever again, once was more than enough.

Bit of a convective weather yesterday morning
