There were a few showers around and about in East Yorkshire yesterday evening, in particular Goole. Later on, at exactly 22:55 there was a light show way out over the North Sea. Intermittent lightning for about half an hour lighting up the clouds orange red. Checked later on NW radar and these showers were in the region of 100 miles offshore and I was a good 8 miles inland when I was watching them. That is quite impressive.

Strangely, when the lightning started, I had been thinking about something which someone else touched-on above. I have often noticed, especially now that lightning strikes can be plotted, that showers in an area can be un-electrified but very heavy for quite sometime and never become electrified yet, once one does in an area, they all seem to. This was clear on Tuesday of this week when all of a sudden everthing became electrified down South.

I have always thought that this was a property of the atmosphere and that the conditions had now become conducive for electrification and, as a result, all of the showers in an area become electrified. But, as I stood in the field looking out to sea last night, it occured to me that it was possible that, once one shower becomes electrified, then this induces the next to become electrified and so on in a kind of chain reaction. I am in no way an expert on this and someone much cleverer than me may well have published work on this in the past, but it occurred to me that this induction idea might explain the sudden electrification we see over large areas as this effect seems to travel much faster through a group of showers than any physical atmospheric property that was changing could.

Musings of a mad man in a field or is there something in this?

I like your theory of this. I did watch a program about lightning years ago and there was a section of it about lightning from space. Where lightning would start and storms nearby would react by sparking off too; so a similar line of thinking to what you are saying.

There are a few strikes showing up on Blitz at the moment on the south coast but nothing on nw radar??

[ElectricSnowStorm]

Their is an old saying"one storm feeds another"..

[Mesoscale]

like dropping a stone into water it creates a ripple effect, did you notice if the lightning radiated out from where the first lightning happened? or was it completly random?

that is the perfect line for the idea, the energy rippling out feeding another cell-like re-cycling cells, this would be in effect of single cells, they last around an hour or less but new ones spring up very close by as the old ones decay.

[Staffordshire]

[Stuart]

Honestly though Stu,
I'm 100% sure that you can't get worst then Cheltenham for storms. I expect you'll even manage to do better then me when you move.

I guess it's probably going to be a 'No' Staffordshire Is it really bad for you too in Staffs? We will get a chance soon me, you, Stu and others .

[Staffordshire]

Aha yep! A thundery storm passed about 8 miles away in May, and on Tue 28th June I had some heavy showers but that's it

[Miguel Hugo Roberto]

I think the BBC has gone bonkers as Wednesday-Friday all feature the thunderstorm symbol for Bristol - chances are there won't be one on either day.

[gottolovethisweather]

Well hello.

I'm enjoying the current settled spell actually in spite of the thunderstorms coming anywhere near me, however.......................

The MetO hint at possibly thundery type showers next Wednesday & Thursday so here's hoping, see http://www.metoffice...st_weather.html

Furthermore, prior to then, the MO Fax Charts at t+48 (attached) suggest a triple point low showing up, so will there be any implications from this as it interacts with the warmer air pushing eastwards, anybody?

Cheers

[Sunny Android]

Looking at GFS forecast, there are no high CAPE values and the Lifted Index are insignificant from Tuesday to Thursday.

It's not humid enough for a serious thunderstorm, well at this location anyway.

I'm also interested on the 'triple point low' and it's part it may have to play in the weather breakdown ?

[Stuart]

you dont need high caps or Liffted index or humid weather for storms
