In all the excitement, I've almost forgotten about this thread!
But, indeed, yesterday (Fri 18th July) at 8 pm, a "surprise" multicelled thunderstorm system moved in from France and slammed head-on at this part of the world.
The leading gust front or shelf cloud. I was more frightened of that than the lightning which followed because those usually produce strong gusty winds (not my favourite weather phenomenon) and even spawn tornadoes (thankfully, it didn't on this occasion).
Once that passed over us, then the "core" of the storm cell arrived an hour later and I got treated to a fairly prolonged lightning display. Surprisingly little rain fell so it made it a joy to spectate and take photos off, as you can see below.
Taken from the relative safety of my front door porch at 9 pm to 10 pm.
And I even got to have a second thunderstorm in the small hours but that was more "causal" in nature and was the one meant to be as forecast anyway.
However, right now (Saturday) we are still under this warm and moist unstable airmass coming in from France so the potential for further thundery rain and thunderstorms will be there for the rest of today and into tonight before it all becomes confined to the very far South East tomorrow.
Then we can all relax as we go into next week with our weather being dry and settled with sunny spells, as well as being warm or even hot.
