Had some very heavy burst of rain but alas the storms have tracked to the North of us. Pity as we would be right under them had it been tomorrow night.

Looking like there is still some possible action for the UK

P.s, I'm South of Angers in France at the mo

The band of rain is really becoming very heavy and producing a fair amount of lightning now. It looks like those in Kent could get very lucky later on:

Sporadic flashes of lightning here once every 1-3 minutes whilst driving back from tesco :) Another rumble as I type!

Been going for around an hour now, add this on to the couple of rumbles heard late afternoon - Not bad at all!

I had one CG about one quarter of a mile away from me the sound was the loudest I've ever heard as I said in SE thread my heart skipped a beat. And the rain is utterly biblical like seriously heavy. In the past 20 minutes I've had numerous bouts of T&L nice. Roads have turned to rivers...

Boredom would soon set in after the third month of non stop action lol. That clip reminded me of the Bournemouth storm from beginning part of July? Just shows how manic that one was for our parts. A real classic that many are still probably talking about.

Yeah gotta say it, that Bournemouth storm looked like the best of the bunch that night. Incredible strike rate it had on it. Think that will top this summer's storm activity unless August can better it somehow!

Towering cumulus going up on local convergence zone , quite dark and threatening too ...

Some further north and into Scotland punched some weight too, not been a bad July for some storm lovers. Always be the storm starved though, even during the most active seasons. Such is ;-)

Thought it would be good to give Monday a mention as GFS is forecasting the centre of the low over northern England which creates a convergence zone in its wake. This low is going to bring a windy day around the centre of the low creating some strong Low Layer Shear.

As the strong jetstream is situated further South Deep Layer Shear will be away from the main area of interest so this won't be aiding convection there however the even more modest CAPE could be aided by the jetstream further South.

Steeper Lapse Rates over the convergence zone and the low centre however not overly steep.

 

post-7331-0-73028300-1437846357_thumb.pn

 

I'm not sure if this is indicative of an upper trough however as above the metoffice fax doesn't highlight any troughs

 

post-7331-0-37135900-1437846484_thumb.pn

 

Average UK temps and Dewpoints pretty close so cloud bases will probably be reasonably low.

 

Any thoughts on this agreements or disagreements will be very welcome :)

The Cheshire Gap effect was evident the first part of the morning before a wind direction change pushed convective cumulus inland.

Wel after an exciting start to July, I must say this month has been very boring (at least here in the W-Mids) not even any thundery showers after the 4th July.

Hopefully August will deliver more of a threat

Just looking at the METAR stuff I archive and noticed these two from EGNS (Isle of Man) on Friday.

EGNS 241050Z 07008KT 9999 FC SCT020CB 14/10 Q1012 NOSIG

EGNS 241350Z 08007KT 050V110 9999 -SHRA FC SCT025TCU BKN046 14/09 Q1012 NOSIG

I haven't seen anything else mentioned about it (either on here or a few other sites - unless I've missed it) ... would've been nice to have seen if anyone did see anything themselves.

What does all this indicate?

Is their a key available anywhere?

I'm sure I knew once, but now over 50 and my grey matter unfortunately has been overtaken by my grey hair!!

Whoops, sorry. I was referring to the FC section of the METAR strings (FC = Funnel Cloud/Tornado/Waterspout)

Top string was reported at 10:50(GMT) [11:50(BST)], bottom one at 13:50(GMT) [14:50(BST)]

Both from EGNS, which is the ICAO (International Civil Aviation Organization) airport code for Ronaldsway Airport, Isle of Man.

There's a free online METAR decoder here, which will show you more information when you paste the string in to it and press the "Decode" button. :)

Scattered heavy showers locally with thunder possible later, NW England into Greater Manchester one area of interest, some pushing further east as the day progresses.

Nothing of interest here except for drizzle...
