    When is this scheduled to kick off? Strikes starting to be visible on the south coast of England.

    Well spotted Ian.
    This tephi shows a nice unstable atmosphere. The big thick red line starts rising at the DALR ( Dry Air Adibatic Lapse Rate which is the puple line). Then at about 1000 meters it condenses and reaches saturation point and starts to rise at the SALR ( Saturated Air Lapse Rate curved green lines). It then rises to about 9000 metres and hits the equilibrium level and stops rising.
    This where the Anvil should form.

    Just need a trigger for the convection now which doesn't look like happening. Too much moisture through all levels

    V heavy half hour of rain here in the north east, which ended with about 5 min of hailstones mixed in...really dark over the mountains heading north but brightening from the south...looks like the sun might come out for a while...would that be enough for some added convective heating later in teh afternoon?

    I don't think it will be enough as the heat from the sun at this time of year won't account for much.
    If the upper air temps were colder it could have been an active day but the temps are a little on the high side at 850mb.
    The freezing level is quite high also with the GFS putting the 0DegC Isotherm at 2200m so any hail forming will be small.

    Yep we are in the wrong place,

    From Ian Fergusson on Twitter

    MetO diagnostics suggest circa 40% threat of potent cells after midnight into S/E/NE Som / Dorset; large hail possible.

    Feckin' SE England again...they had decent fireworks last week too.

    I'm pissed...where the hell are the T storms we used to get here years ago...I think we had maybe 3 storms here all year and they were nothing special either. Climate change is supposed to be making the atmosphere more turbulent and energetic... not less.

    Fun to be under that rapidly developing shower over Kildare, started as mere pink blob over Carlow, and look at it now. Torrential rain fell here in S.Kildare for at least 25 minutes, backed up garden drain which is becoming a regular occurance. Never expcted a whiff of thunder today, but Im good with downpours.

    Some nice formations almost like mammatus over Galway in the last hour, driving and no camera so no pics.
    At same time weather report on radio said remaining dry with sunny spells in the west, it has been raining heavy since then...

    Some serious downpours around London on the HI RES a while ago.
    Friend in North London says there was a river of rainwater flowing down the road.

    May not be anything notable, but I'd happily watch time-lapsed clouds for hours anyway.
