A new thread ahead of any potential action later. Although we are all as excited as kids before a birthday party, can we try and stick to the subject as much as possible please?!!! :lol: :yahoo:

Slightly worried now as it's brightening and what has just moved through WAS thundery. Need some sun to get to work to help intensify these showers back into storms.

30.7 here now. Gone slightly cloudy too. Nice breeze though!

Would anyone like to guess my chances of seeing something this afternoon/evening?

Thankfully the high cloud that moved into my area is melting away with sunshine returning. Incredibly hot across E Anglia with temps widely around 31C with 35C being recorded in the shade in my garden. Amazingly its hotter here than in London which is rare.

Everything is going according to plan in my opinion and I eagerly await this evening.

Some very interesting cloud formations at the mid level here. The humidity has risen significantly in the office and I have a headache forming. Typically we tend to be a good breeding ground for storms in this part of the country.

I don't get it... Theres currently 2600 CAPE over my post code with -8 lifted index and all there is to show for all that thunderstorm potential is a very small light shower within 50 miles :doh:

Must be a pretty strong cap in place at present, with the little shower coming from a Cu underneath.

Will it snow in Lo.....oops sorry wrong thread.

Although, from reading these El Gordo threads it would seem predicting storms is as complicated and relies on as many different factors as forecasting snow.

It's very hot andf humid here too in S London but skies are clear.

Cirrus/haze now arriving here - to the east it's still clear, but the western sky is very hazy. Hopefully, based on others' reports, it shouldn't last for too long. Look East dollybird predicting storms from late evening through to around 5-6 am tomorrow.

Can someone more knowledgeable of storms than me explain how a cape of 2600 and a lifted index of -8 in 30c heat can only produce a light shower? I would have expected fireworks with conditions like that!

A really strong CAP in place keeping a lid on all that CAPE. We need the forcing to break the CAP, which hasn't happened anywhere yet, unfortunately :(

Perhaps the GFS is overcooking things again? Although other ingredients are needed to fire off a storm than just CAPE and LI.

nicely clearing up here in south herts 30.8C hopefully we can gain a couple of degrees! Just a bit worried I might be a bit to far west to see anything good.

Convective Inhibition (a "cap" basically) can prevent storms initiating on days such as today
