Attempted a chase today into north Notts and then Lincs. Plenty of heavy showers and photogenic skies but no thunder or lightning today. If I had been about 40ish miles east towards the east coast I would have probably had a treat, but I didn't get that far. 2 successes and 1 bust so far in 2023. I can't win them all.
Back home now, going to start editing yesterday's footage.

Wow you covered some miles @Supacell...hope your windscreen is ok with one inch hail
...
Yes herts yesterday was amazing, once the storms kicked off mid afternoon they just kept going with repeated jntense rain and hail and loud thunder...storm chasing in reverse as the storms were coming to me...
..off out to do some more gardening jobs today...lovely sunny start but again will be interesting to see what develops later ..take care on the road mate...look forward to more reports...
My windscreen was fine
. The floodwaters were my biggest concern to be honest.
Still uncertain whether to chase today. It doesn't look as good as yesterday. I won't be doing any long distances but may be worth me taking a trip out if something develops locally.

Love a good old day of thunderstorms. Had a few nice strikes north of cov yesterday (attached), and a short clip of the CG I got too.. just a mention - how can you work out whether they are a positive or negative CG, just by the flash or by the rumble?
If i remember from previous reading i have done. A positive lightning strike sounds like a sudden explosion rather than a long rumble. To look at, a positive bolt looks smoother as it is composed of just one stroke, whereas a negative strike has multiple strokes.

A busy chase day yesterday with LOTS of pulse storms to deal with. Again, it was at times frustrating to reach a cell just for it to pulse out. On the plus side, reaching the cells was not difficult as they weren't moving fast.
Most of the storms I witnessed were from a slight distance away and so offered me cloud structures, distant CG lightning and thunder. A lot of heavy rain with lots of feint intra cloud lightning and then a sudden bigger flash and big boom.
The highlight was as a storm actually broke out just a couple of miles to my north and so I was able to get into it and drive through an impressive hail core. I'd say the hail was about 1 inch in diameter and it was coming down fast enough to turn the roads icy. I cannot remember exactly where it was as I covered a lot of miles yesterday and my ageing brain isn't great at remembering details. I'll know when I edit the footage.
Another thing there was a lot of was flooding. These storms were dropping a lot of water.
Ended up travelling all the way from my starting point near to Nuneaton down into Hertfordshire. But by then the main storm activity was becoming further and further southeast and so I headed back home again.
Not bad at all to have done two decent storm chases by the 10th May, with the possibility of a third chase today (depending on latest forecasts etc). Makes up for the lack of any real warmth so far this spring.
Edit: Hailstorm was just southwest of Desborough, Northamptonshire.

Currently between Ashby and Atherstone eyeing up the cells to my west on radar. Was on route to further south but made the decision to stop and see if these could deliver.

Great job as always Supa
Lovely structures and colours to the Humber cell
....and you even found a red telephone box
loved it
Thanks Arnie.
Haha, the good old red telephone box. There are still a few round here, they are being used as mini libraries. No UK storm chase is complete without one

Good decision to go there but both the plausible targets have done well just a widespread day in general. Looks good for a timelapse that one.
It has been a good day for widespread storms, although the pulsing nature of them was frustrating at times. The storm in that photo died out before it reached me. Still a good day though and did get under a pretty nasty storm earlier in the afternoon between Howden and Pocklington with some hail and CG lightning.

Photogenic storm moving over the Humber

@Eagle Eye Thanks. Already committed to the storms that will hopefully develop further north now though. Currently near to Snaith and looking south it appears clouds are building.
Arome is showing some intense precipitation around here from around mid afternoon. Going to have a picnic in the sun and then see how it looks.

If anyone does head this way plan around avoiding the A1 north of Doncaster, horrendous roadworks will kill you.
I'm in Doncaster now, thanks for this.

I suspect thst would be a bit too far north given the gravity wave comes from the convergence line so you want to be really close to that but not on it. You'll then have a good view to your south and hopefully storms around you so you can make a decision on where you chase for better views.
Ok thank you. I've been chasing for years but have very limited meteorological knowledge. I tend to rely on others for that part

I'd go just north of the convergence line there. Open sector promotes best widespread viewable convection. It'll be better to photograph than the saturated areas south of the convergence line and the messy line. The open sector with warm temperatures especially with the laminar flow layer temps will promote less saturated air compared to the convergence line. That half open warm sector in Lincolnshire appears to be getting ready with some gravity wave enhancement of the bouyant layer between the convergence line and the clearing cloud to the north.
Maybe somewhere to the north of the Humber would be better then?
-
Although storms could occur pretty much anywhere I am planning to head northeast, probably settling somewhere in North Lincolnshire area. Fingers crossed it pays off.

I am keeping my eye on tomorrow for widespread storms, probably the most widespread we have seen so far this year.
Even today the odd flash and rumble cannot be ruled out, more especially across southern and southwestern areas today and then maybe the south coast overnight. However, I am not seeing a huge risk with CAPE not overly high.
Tomorrow looks to be a classic May day of heavy showers and thunderstorms developing inland in response to daytime heating. Cold air aloft across England and Wales especially, along with strong May sunshine should help to bolster CAPE values up to around 1000 j/kg, building north-eastwards through the day and eventually away to the east through the evening. Shear is fairly weak and so pulse type storms are most likely but these could tend to congregate along convergence zones. They will also be slow moving and so flooding could become an issue.
It is too early for specifics as to where the greatest likelihood of storms will be but my current thinking is the main risk will shift north and east with time, meaning that by later in the day the showers may lose some intensity in the southwest, whilst they become more intense to the north and east. There appears to be reasonable agreement on a good thunder risk tomorrow and so I will be out chasing.

I am quite close to the risk area today and so, although the risk is low, I am prepared to get out for the first time this year. It is a low probability that I'll actually chase but if I do I'll be heading towards the Peak District on the Staffordshire/Cheshire/Derbyshire border for about mid/late afternoon time. There are some good views to the west from that part of the world. Very uncertain outlook today but the sunny start should help.
This is the sky here.

Speaking of bog roll. I forgot it was going to go off and nearly had a toilet accident

sferics just gone nuts to my south,...near Derby
@Supacell,...you hear thunder?
Yes, one rumble of thunder along with a bit of hail. First thunder of the year. Not able to chase today though, but then moving a but quick to chase anyway.

I was planning on waiting until April 1st to open a new thread as this is when I tend to become interested in all things convective again. However, considering there has already been some convective interest over the last few days and indeed more to come during the week ahead, I have brought forward those plans. It is a joy to be seeing decent opportunities ahead for thunderstorm risks as early as March. Welcome back all fellow storm fans.
So here we go. Old thread below.
And as for these opportunities. Well the forecasts on TV are already mentioning "thundery" in the forecasts for tomorrow, but my interest is further ahead with GFS, NMM and UKV all showing interest for Thursday onwards especially as an area of low pressure parks itself close by and generates lots of showers, some of which are likely to be thundery with hail. We are not talking intense summer heat and plumes of course, but some nice springlike thunderstorms with good convective skies and rainbows.
Admittedly I am more about chasing than forecasting, I sometimes try to forecast but I am best leaving that to the experts. I can though, see the opportunity. If I capture a thunderstorm within the next week, it will be the first time I have ever captured a thunderstorm in March and 2023 will be my 20th year of storm chasing.

In many years i see March as being the month where snow is most likely to fall. Its just not the month where snow is most likely to stick.

A decent blanket of snow in Belper. Nothing like the nearby Peak District but it'll do
. Enjoyed a nice snowy walk this morning.

Storms and Convective discussion - 20th March 2023 onwards

It's taken a while to edit as there was a lot of driving in "nothingness" to edit out and also been busy with work commitments since the chase. But here is my video from my storm chase on Tuesday 9th May.
Chasing pulse storms is difficult but I'm happy with this month so far from a storm perspective. I am hoping for some good thundery plumes or at least more organised thunderstorms as we get more into summer.
