South West and Central Southern England Regional Weather Discussion 21/05/2018 Onwards


Recommended Posts

Just checking in on the UK Southwest Storm Chasers FB page, and it turns out there was a nice little storm over the western part of Cornwall last night (around midnight-ish)? Anyone under that at all?

So all the instability we saw floating over before sunset did end up with a storm further west!?

A friend on another forum was right under it, they live just along the coast from Newquay and said that it was a rather rude and unexpected awakening!

Two days ago the high was 27.1°C, yesterday was 27.2°C and today’s high so far is also 27.2°C although could go above that as it’s rising again now after briefly dropping.

Yes, I was ! Woken with a start at just after 0030 by a very loud and prolonged peal of thunder here in Newquay. There were a further 3 flashes and bangs over the next few minutes but at increasing distance. A look at some of the lightning reporting sites indicated that the first strike was probably no more than a 150m from the house so no wonder it was loud. There was a brief accompanying period of rain, big drops but with no intensity, but this also stopped after 5 minutes or so. As well as the proximity of the first strike the most surprising thing was the fact there was a storm in the first place. Even when sitting outside at 11pm, other than a few stray clouds, there was no indication of anything like this happening !

Wall to wall blue skies today, more blue than last few days. ‘Felt’ a little cooler than recent days with the breeze, but UV must of been high. Mowing a big lawn for a customer this afternoon for 2 hours on a slope facing SW has topped the tan a little. Work boots need an airing now...

I was surprised how windy it got this afternoon, really gusty at times. Nevertheless, another 28C day and uninterrupted blue skies and sunshine again!

After the sudden drop in temperature earlier this evening, which was caused by a brief sea breeze after the NE'ly dropped, it's been stuck at 19.5°C for a while.

Tomorrow's convective risk reminds me of a period back in the Summer of 2013. There was a low risk that evening, but some cloud developed to my Southwest which I kept watching, and then it became electrified. I went to the pub that evening, and it was still moving slowly towards me, with plenty of lightning, but no audible thunder. As it rolled in, a huge gust front hit! The pub's umbrellas all went up in the air, sh*t flew everywhere! And then it all went nuts with rain/thunder/lightning for about an hour. I might have to look through the radar archives, as I thought I remembered it being quite isolated. The same tomorrow night would be most welcome.

Found it! July 21st 2013. What helped me was that I was watching a new Top Gear episode that evening, so I looked up the date of the series. :D

Another slow start temp wise however assuming no sea breeze develops we should get to 27/28c again today.

Also a chance of a dry TS tonight, could cause problems with fires!!!

Warming nicely with a breeze keeping things, humidity levels just below 50% with the suggestion that these will increase over the coming few days making it less pleasant. Looks like for the potential for a drop of moisture is being pulled back over France as the low sinks rather than comes ashore, but still something to play for as Mapantz eluded to yesterday, just not looking quite so promising.

We have joined the 25C+ temps over the last two days with a more limited sea breeze (one still arriving in the afternoon but having less of an effect) . My station registered 28.6C on Thursday and 28.4C yesterday.

The nights have warmed to double figures with lows of 11.4C and 11.1C so still relatively cool in the valley. A station 40m higher, about a mile west of me had 15.4C and 14.0C lows.

Currently 25.8C. 

I'm off to Reading this afternoon, so there will likely be thunderstorms down here tomorrow!
