What a day for some of us lightning fans, even though I had to work, luckily it allowed me to be outside for much of the afternoon. The storms kicked of over us just before I left for work at 13.30 and didn't let up till late afternoon and into the evening, the wife said the thunder disappeared into the distance at around 19.30-20.00. All the lightning I witnessed was directly overhead with fork lightning pretty much continuous with very loud thunder that you could hear even over the noise inside the buildings. The rain at times was torrential with pea size hail on occasions, we had one report that the north side of Frome had some hail almost as big as golf balls but not so sure about that as my stepdaughter lives that side of town and she hasn't mentioned anything anywhere near that size. The rain here totalled 26mm for the day so not as much as Gibbys patch but certainly enough to raise our local river a fair bit.


I'd go to say that was the best series of storms I've seen in many years, the wife and dog on the other hand hated every minute of it and she said she sat watching a couple of dvds with the sound turned right up. The only thing i wish was different is I would have preferred them at night, much more exciting.

In the distance the storms looked more like snow shower they were so heavy (the old visibility reduction thing). Epic. Warminster itself missed most of the action, and I watched the line of storms sliding across the NW side of the town towards Westbury for much of the evening, with thunder rumbling away. Great fun.

Why is the south east so poor for Thunderstorms? Even the stuff that comes up from France misses us!

  French imports are often associated with a Spanish plume and that is quite a rare event at the best of times anyway. I'm not sure if they have always been lacking or we have become more aware of it as we get more into meteorology so we end up getting frustrated about it. I'm guilty as charged of that, that's for sure! But when they DO happen, boy, we do know about it (such as what happened last week).
  Put all that together and what with Kent being a peninsula type land mass surrounded by seemingly cold seas and it's hardly a wonder why we do keep tending to miss out on the action. However, having said that, we have had our own fair share of the interesting stuff (I could never forget August 12th 1996).

We missed out on most of the snow last winter and have missed out on most of the storms this summer. Seems Kent is only good for warm temperatures and sunshine (and who wants that ).

A great image that one Ian. I could almost smell the rain at times here yesterday, yet it stayed dry throughout. I suspect this afternoon may be bring more in the way if convective showery activity here.

Hope this works, my very first pic of a bolt of lightning, this strike is over Gibby's area of Radstock, the quality is pretty rubbish and being through a window I've some reflection of the camera on the glass.

A couple of pics from yesterdays storm. I drove from Alton to work(Basingstoke), setting out at 1800z. This was the scene looking that way at that time, the cell to the right being responsible for a fierce storm in the Basingstoke area shortly after



I managed to stop the car south of Herriard, about 6 miles short of Basingstoke to capture the approaching cloudbase which extended right across the sky from WSW to ENE. The eastern end was where the main cell had gone by 1815z and had thrown out an impressive CG, flashing forward of the rainband in a rather dangerous manner a minute earlier! As I mentioned earlier, the road flooding just S of Basingstoke was spectacular

There's just been a heavy convective shower here in the past half hour or so although I did not notice any electrical activity. Nearby Aberdeen Airport was reporting a thunderstorm at 2:20pm (BST):

Based on the view in that direction recently I am not surprised:

I missed a cracking thunderstorm yesterday at home and exacty the same thing happened today - no storms really in Belfast (apart from a couple of rumbles yesterday) but full-on storms back home in Bangor both days!


My weather station reliably informs me that a rainfall rate of 144mm/hr was recorded at 4pm

The incoming plume will certainly bring some instability. I had a look at the soundings for tomorrow afternoon which show appx 1000 CAPE at Leeds and 700 at Herstmonceux with instability from mid-levels to over 33K ft.


So some good potential although forecasts are focusing on the SE and East Anglia later tomorrow for storms

ESTOFEX have issues a Level 1 for Ireland, N England and much of Scotland:


http://www.estofex.org/


Extract:


Current thinking is that showers and thunderstorms will develop in the warm air advection regime. These storms will have a good potential to organize in an environment with 10 m/s 0-3 km vertical wind shear and also around 10 m/s bulk shear in the lowest kilometre. The rather broad overlap of low-level vertical wind shear and CAPE supports a threat of supercells capable of producing tornadoes. These storms may also produce large hail. Furthermore, bowing storms may form with the main threat being severe wind gusts. Highest potential is expected across western Ireland. Late in the period, the cold front moves eastward. A few severe wind reports may still be possible until the morning hours.
