    Too early yet but latest GFS run showing signs of a heatwave sometime in the first week of September, could be the next chance for possible storms. Though of course it's still a good two weeks or so

    Stonking day for storms. Had two cells with continuous thunder [but mostly no visible lightning again]. Here's some pictures of one storm that I tracked as it progressed up the M11 which produced some

    Am enjoying a weekend away 60 miles S of Prague in the pretty town of Písek, the storm front that came in this evening was dramatic! 

    Didn’t know we was expecting an avalanche today 🤔

    Literally not believing anything until the day it happens.

    2020 has teased all the fun out me at this stage. Will keep an eye on developments, but the odds of a storm here in the south east is vanishingly slight. We would need a miracle

    Thunderstorm warnings here in the Czech Republic today, chances of severe thunderstorms, hail, torrential rain, wind gusts up to 90kph (60mph) and they mention the possibility of supercells. It’s definitely windy and I can see tops of storms towards the W

    So what triggered off the storms over the North Sea?

    It was night, so no diurnal convection.  It is not like winter with a deep cold airmass over a "warm"  North Sea. It wasn't topography.

    I heard it was something to do with the plume interacting with the edge of storm Ellen, plus was elevated when over the sea so not reliant on surface heating.

    The elevated storm I saw in June seemed to lose its intensity over land and pick up again over the north sea.

    I'm calling it. I think today will provide some nice surprises....

    What bit are you in? Would be interesting to see how things develop via radar.

    Probably

    There’s a curious feature moving SEwards from wales that day, but CAPE is meagre, so you’ll probably just see some heavy showers developing by evening.

    It's from Wales what's the problem😀

    The land track it takes is favourable, but even if it were to initiate in wales as a decent storm it needs the right conditions to stay organised, and plenty of energy, which at this point is highly unlikely. Ironically this is exactly what we needed the other week directionwise, but still it’s better than nothing.

    Probably at least two weeks now before anything of any convective interest pops up again

    We had a bit more lightning here on Thursday night along with probably the most heaviest rain I have ever seen.

    I could tell something was up that night as there was faint heat lightning going on at 10:00 to 12:00PM. And then later some brighter fairly close sheet lightning occurred with distant rumbles.

    There was a lull in the lightning but then a massive downpour happened and by the end of it there was a very large and deep puddle of water outside our back door which thankfully slowly seeped down our soak away to the bottom of the garden. And as the rain moved away an intra-cloud strike occurred as the light was on in the kitchen which I saw light up the ground outside the window above the house which produced a closer rumble of thunder.

    Then there were a few more distant strikes around the area with distant rumbles until the lightning and heavy rain moved away leaving the winds to arrive and normal showers.

    It was night, so no diurnal convection.  It is not like winter with a deep cold airmass over a "warm"  North Sea. It wasn't topography.

    It was essentially the edge of a plume being drawn northwards from western Europe across the North Sea towards Scandinavia, becoming engaged by a pronounced shortwave swinging northwards (that also aided the increase in lightning activity near Wales/SW England too). The models had been playing with the idea of elevated thunderstorms erupting close to the East Anglia coast as early as Monday from memory, so not bad for a Day 4 forecast.

    Have been getting a constant rumbling for the last hour or so, that sounds like elevated thunder.  The radar is clear,  no visible convection.  Wondered if it really could be an elevated storm?

    I think it's strong winds.  I think that's what I can hear in Newbury where I temporarily am
