A great feature of the NW radar is being able to zoom right in on heavy showers and see how quickly they develop. One over Devon went from a slight blue dot at 13.55 to rain rates approaching 100mm per hour by 14.30!!

Just noticed that MetO are now charting a potential triple point to drift over the south coast tomorrow night (which is why I presume Nick is thinking possible thunder for that period)...looking forward to seeing how that pains out!

Is that a typo Harry (meant to be pans?), or intended anticipation of a painful, fruitless wait?! LOL

The gap in the line found here and it broke up, with really heavy showers just to the north and south. More Cb tops visible to the east 20 miles off.

Hope something kicks off in the next few hours as I should be in a hot spot for heavy showers today but haven't had anything, just broken medium level cloud all day.

Showers gathering again west of Norwich. Yesterday they inched eastwards and gave thunder, but I have my doubts about them doing the same today.

Yeah it was a typo, though as you point out I am wondering whether it was some form of Freudian Slip :wallbash: lol

There is a SE/ESE flow which is probably the same along the South coast in the form of a sea breeze which pushes clouds inland. Very often the South Coastal areas get the best conditions in set ups like this - very similar happened yesterday. Also, when HIGH pressure is in charge there will generally be clear sky over the English Channel even when Cumulus builds inland.

Hmm, just looked at the extra data and theres heavy showers with lightning detected not far from me which has come as a surprise to me as it has been overcast with low cloud all day here.

Does feel very storm weather like though, very warm and sticky almost tropical feel to the atmosphere.

Hi TWS,

I agree, if only for the fact that temps have managed the giddy heights of 18 here today, also, there's a bit more of a drift off the sea, pushing the clods and showers further West, it does look REALLY dark to the West but quite bright here. Can see some convective towers to the south, but nothing to the southeast which is where I'd expect anything coming from today

Only now have some really nice solid looking tower gone up nearly all around. A dark cloud that moved overhead has now developed rainshafts to the SW of here and probably giving Weston a downpour. More ones developing east of here too so hopefully something before the day is out. :)

Oh yes, so there is :)

Skies are looking quite interesting off in that direction - hopefully I will get to drive through it en route home, but it may slip just to the South of me (as per the norm lol)

Nice looking towers appear to be going up N of London also!

The sun has been out now for a little while so obviously a bit of heating may be doing the trick :D

Large downpours have developed top my East recently. All seems to have only recently sprung up. Crackles on AM radio. :)

Amazingly it has managed to stay dry here all day, with some very heavy showers breaking out just north of here and also plenty of convection looking out to sea over SW England. It has felt humid and muggy with light winds. Lets hope for a downpour but looking at the current radar, looks like most of the coasts will stay dry.

Radar looks pants for this 'development' in S London...I'd say false alarm lol...excitement well and truly subdued.
