Convective/Storm Discussion Thread 25/5/16 onwards

[Nick F]

None of the most recent model runs (ECMWF, GFS or NMMM) picking up the heavy showers/storms developing along the E Sussex coast recently, though funnily the 00z ECMWF this morning did break out heavy downpours across the SE overnight. BBC forecasts were suggesting this would occur, as did my forecast earlier today.

Be interesting to see how this evolves overnight, as a stronger flow aloft and vertical shear now across the SE.

sorry jtay in answer to your question the pub is the Yew Tree

 

Ha small world, my uncle and aunt used manage the Yew Tree inn many years ago. Fond memories there! Snow was always better there than my location in Southampton.

Anyhow, few flashes of lightning here this evening. Potential seems better tomorrow afternoon, fingers crossed

As we're not going to 'officially' announce all this until tomorrow, I thought I'd re-copy it in here for those watching the storms tonight!

Hi Paul - I can't remember which radar did it, but one of them used to detect your location on a phone or a tablet. Is it possible to add it to the V7? I liked logging in and it automatically zooming to my location. Also, would there be a possibility of adding in a dark map background further down the line? Apart from that couple of suggestions, the V7 is excellent, by far the best radar I have ever used!

[Mapantz]

Wow - Michelmersh is getting absolutely battered! I only looked about 10 mins ago, and the station was at 20mm.

Thanks and yep - it should have location zoom built in actually, so maybe a small bug in there if you're not seeing that - I'll get it marked down to be looked at. We've been working on new map backgrounds recently too, so watch this space.

Distant flash spotted from Wokingham  no thunder though

Probably a bit far now for me to get. I am south of Swindon pinning all my hopes on the cell north of Southampton :-)

Regarding the radar, still use V4 as it has the image 'smoothing' visualisation and no lag in loading different frames.  Only thing that I would really like to see is an option to increase the animation/loop speed, which would be ideal for quickly determining the track of storms.

@Nick F HIRLAM has picked them up...

 

Very interesting indeed for what it shows for the SE later on....

[Frosty hollows]

Looks like it's losing intensity. I had my eye on the 'cell' emerging from Newbury earlier. Unfortunately it faded really quickly as it moved N but despite a moderate shower showing on the radar I had no rainfall at all.I swear my garden has its own microclimate!!

[Ben Sainsbury]

Lightning Strikes seem to be so random across England right now!

[A.J]

yes, just spotted a distant flash to my south....judging by the radar it would appear to have come from a cell near trowbridge

[Flash bang flash bang etc]

Well frustrating evening's chase. As always I pushed on past where I was planning to stop and ended up near Bristol where everything seemed to peter out.

BUT after returning to Woking to drop off work things and driving back down the A3 toward home I saw a flash immediately ahead - albeit up and ahead - ie. Far away in the tops of that Winchester cell.

Having already promised I'd be home with cider to watch some Friday night TV I gave up the chase - which with hindsight would have been a simple 30 min drive up the A31 to Farnham and beyond for some great views of the storm(s) coming up from Southampton.

Still, I could see the atmos flashes from our spare room tho there's a hill mostly in the way in that direction.

Funny thing I noticed tonight however was the temperature as I drove back along the M4 - Bristol was about 15 degrees but it jumped up to 18 as I passed through Reading. Woking area was back down to 13ish. On the way down the A3 and passing Guildford it was creeping back up toward the 15 mark.

Was this some kind of warm sector which was feeding the more recent cells?

Active cell Near Brighton

[alexisj9]

Just had lightning here, going by how the other storms have been, not expecting anymore, but I guess we'll see.

 

[Speedway Slider]

Are these elevated? Sparking off over the channel, I suppose they must be...

Oh, and Worcester picking up again...timed @ 02:40

[10 Days Away]

Tho ones off the Kent coast appear stationary. Bit of a shame.

[timeless]

dammit l can hear thunder

[Speedway Slider]

Hmmm, creeping slowly North, and now Eastbourne has some action!!

[Speedway Slider]

Maybe Birmingham/Wolverhampton going to get tagged this morning ? (03:00hrs)

Elevated clouds coming into the are, lit up by the oncoming sunrise.....If i remember right from past elevated events this is a good sign

[NO LONGER POSTING]

Cell just fired down at Brighton 

 

Up nice and early as some models break thunderstorms out this morning for the south East and so far so good 

[Supacell]

Saw some distant flashes at around 2am last night from the storms that broke out between Gloucester and Hereford but other than that a quiet night for me. I managed about 2 hours sleep overall in the car.

Awaiting the mornings model runs but currently my eyes are on Somerset from around midday. I'll be getting a strong tea and a fry up first though :-)
