Storms and Convective discussion - November 2023 onwards

[Metwatch]

Decently sized hail earlier just east of Plymouth. Quite strong updraughts and wind shear in some of those intense thunderstorms, and over 100 3CAPE ahead of the storms on an AROME sounding forecast in the area.

Lightning here.

Slightly surprised with the hail to be honest, strong low-level winds with that low-level jet and modest deep-layer shear. That likely means that it's surface based and the low zero levels allows it to take up a lot of energy in the hail growth zone. 

[Andy Bown]

Lightning then thunder in Warminster again! Mad 20 hours of conditions!

 Sparkiee storm Heard a lot of that tracking just to my west. If only it was a more southwesterly flow, I'd have had a more direct hit! Still... 2nd thunder day this month.

Pretty convinced this is rotating i just dont know ho to report it to torro

 Dxnielwashere It’s is torro if you want to report a tornado

Shotgun thunder a few minutes ago, was getting ready to record when it happened.

Edit: Another one but quieter just now

Looks like it missed me by a mile, no hail here.

Pea sized hail, possibly weakly marble sized here, loud thunder and rather frequent lightning. Left a deposit of hail on the ground.

Weren't recording at the time but perhaps some weak rotation as it passed over. What a way to start convective season!

Seeing the radar is giving me good hopes for thunderstorms this Summer, could be a good one hopefully

We were supposed to be setting off out on the boat this afternoon for Easter, currently sat by the stove watching very strong gusts and torrential rain for last hour, with no end in sight.

If we clear the squall line, we might risk it later!!

2024 is off to a cracking start for some. Can easily see the high sheared environment so not surprised to see some of these storms are long tracked with hail and possible funnel clouds. Nice to see some in the Midlands too. Looks like a hook or 2 in South Wales.

Best I managed

Captured the backend of the cell here:

Second March in a row now with a thunderstorm here which is decent going after none between March 2015-2022!

 Dxnielwashere That is a cracking funnel cloud there mate!

Interestingly the cell undergoes a split right before you observed that funnel cloud.

[The Tall Weatherman]

Big-time storms heading towards Northamptonshire and surroundings right now. 
 

Lightning frequency’s are great for March   !!

[Andy Bown]

The first time this year that a storm has intensified as it lifts over Salisbury Plain. Stunning CG and shotgun thunder a few minutes ago. Very frequent lightning from it! 

[TJS1998Tom]

Weather app suggesting 40mph winds around 6pm, guessing this will be a potential squall line

[matty40s]

Looks like we are going to have a direct hit.....

Black dot NNE of hail cell..

 

[CoventryWeather]

 matty40s any visuals of it? Would love to see the structure.

[matty40s]

No chance to see structure, it was torrential before and then just changed to small hail, medium hail and then...

This thing has tracked for at least 120 miles now

12z GFS proximity soundings from 15z and 18z. Decent cape values, helping to maintain the cell although could well be starting to run out of instability as it tracks further north east. Im not surprised with the amount of lightning this things been producing, likely due to the steep lapse rates throughout the atmosphere. Interesting to note the bulk shear values, anything 30+ knots is good for supercells, not sure if this is a true supercell (unless anyone on here can confirm) but that level of bulk shear is certainly enough for updraft-downdraft separation though, could well be the reason this thing has been so long lived. Am surprised with the amount of hail this thing has been chucking out though. 

Really happy with today, not expecting anything here in Birmingham but still just nice to see proper convective weather return.

 matty40s Holy s#@t.

[Metwatch]

Looking east to that storm / possible supercell near Northampton about half an hour ago:

Another shower passing here at the moment which looked very dark ahead of it. 

Jack got the best capture of the lightning and thunderclap which went through Coventry then Nuneaton:

 matty40s That's decent sized hail for the UK. 

Makes the hail here look normal.
