Storms and Convective discussion - September 2024

[Danunosus]

 Eagle Eye Jeeeeebuz! That's epic, yo. There was a huge one here in Newbury earlier, too, connecting disparate showers/thunderstorms. Was really nice to see. Took a load of pics, but I'm too tired to edit and upload them just yet.

 matty40s Where we are flooded, they have pumped 10 tankers full of water which is so far the size of two Olympic swimming pools,millions of litres and they still had a way to go. Makes you wonder where that water will end up. 

[WeatherArc]

Wondering if the lightning from this little cell off the coast of Norfolk and Lincolnshire can be seen, its absolutely pumping strikes out at the moment

 WeatherArc Too much low cloud around. 

24C here last Friday, can't see those temperatures happening again this year. Weather looks fairly boring now for a while. 

[Frosty hollows]

Suspected tornado in Abingdon yesterday (not my photo, so no further details)

 matty40s Just shows Southern Water are an utterly incompetent organisation, in my opinion.

It's been unusually wet since end of June 2023 and - they're running out of water? They have to import it from Norway !!??!!

Typical monopolistic privatised utility, most of which seem to deliver bad service for high cost to the consumer. Companies which are not the result of entrepreneurial effort, but were just created by Thatcher and run by people who know that they can get silly rich with our money doing b-all. All in my opinion, of course.

We were left without water for 48 hours twice within two months. Once in Dec 2022 because they couldn't cope with the end of the cold spell (and a very tame cold spell compared to 1986 or 2010, for example) and once in Feb 2023 in the middle of a mild benign spell for no apparent reason at all!

Back to convection, I did see an unusually active Cb system some distance to the NE of the Southampton area yesterday at 1700. Seemed to resemble the sort of intense convection, with new growth merging with existing Cb anvils, that normally requires 30C and intense humidity to achieve - rare to get that kind of convection over land (as opposed to over sea) in the winter half of the year, and with temps not even close to 20C, let alone approaching 30!

Not sure if anyone was under that, would guess the Petersfield area?

Here it was just 'nuisance showers': occasional heavy downpours but without dramatic cloud formations or dark menacing skies overhead. Something which the south coast generally seems to excel at!

21 hours ago, Metwatch said:

Finally a decent storm passing just east of Coventry an hour ago, dropped a few nice bolts. Sadly wasn't recording on drone during the best one but the other 2 still really good.

 

Possibly the same strike above I captured around 15:00 landing in Wolston:

 

[Danunosus]

 Summer8906 I was in Newbury at around this time watching Cbs to the south and south-west. Indeed, the incus formations up top were merged with each other, which was surprising to see, given how distant and disparate each cell was. (Well, there were distant cells to my south and south-east, with the convection heading in from the south-west being linear. But they were all connected by those incus formations. Pretty extraordinary to see. Will try and post a pic soon if I have the time!)

 Metwatch Nice gunshot thunder! Sounds like a close -CG.

[Supacell]

Here is the previously promised part 2 from Saturday, when the storms did something unusual and went straight over Belper. Although the best lighting is as the storm moves away, didn't see many bolts as it passed overhead. Taken a while as not had time to edit it due to work, but here it is:

 

 

[Summer8906]

There seems to be a small cold pool travelling NW-SE within the N or NE-ly airmass on Tuesday on GFS 06z. Could this produce something thundery?

Origin seems to be from a small slack low currently in the Iceland area and forecast to migrate slowly SE.

In the swirl of that meso feature from yesterday evening.

[A Face like Thunder]

Severe weather on the way it seems, with a yellow weather warning for wind already in place for SW England and Wales and a rain warning to come into operation at 4pm for large chunks of E & W overnight and into tomorrow.

[CoventryWeather]

Funky clouds ahead of a band of showery rain. 

Looks a lot like mammatus, unsure if it is though. 

 

[Sprites]

Turbulent downdrafts from the rain and whales mouth, does look alot like mamma as you say, maybe some mamma thrown in to. 

Edited September 29 by Sprites

[Metwatch]

Some interesting structure to that line of rain indeed, almost looks like mammatus. Seems to be some sort of an "elevated outer band" of rain ahead of the low pressure and associated warm fronts.

Edited September 29 by Metwatch

[Andy Bown]

 Metwatch that was shown on the fax charts as an upper warm front. Usually most of the rain on them evaporates before reaching the ground.

[Flash bang flash bang etc]

Just utterly terrible weather.

 

That’s it. Quite simply.

[Andayxd1]

Heading along the M4 yesterday. Taken by my colleague. 

[Reefseeker]

About to fly to Heathrow from Larnaca, Cyprus. Apparently the headwind is so strong, we're expected to arrive 30 minutes late and should expect turbulence. Yayyy...

[TJS1998Tom]

Not quite thunderstorm related but not had rain this persistent or heavy in ages

[Liamkaboom]

 TJS1998Tom Same here, 30mm precisely today according to my weather station!

[Supacell]

Locking this thread now for the new month.
