    Do I bother going into the MAD thread tonight? What’s the mood like in there???

    I wouldn't bother, all a bit rubbish tonight. Hopefully tomorrow the models will pick out on something to make us cold?

    Good shout from Leon, just read back the last couple pages and it’s just a load of crap, like Paul said in there, the ‘banter’ needs to be relaxed because it’s just monotonous, makes me want to not bother reading!!

    Sorry, I had already gone to work when you posted and missed it until now. The highest points on Mendips is in and around Priddy/Charterhouse, there are some lovely walks and lots of public footpaths. Or if you don't fancy trekking cross country and risk getting lost, head to Stockhill Woods just outside Priddy, it's Forestry Commission so you can wander at will. There are broad, hard surface paths that criss cross the woods or you can wander off through the woods, plenty of parking there too. The woods are about 280 meters asl, so if it's marginal it's usually snow up there, being mostly conifer, when there's snow it's like walking through an alpine landscape  This is what it looks like up there (don't get excited, this is a couple of years old).

    No worries, thanks for that though I’ll bare that in mind for future. Ended up having a short walk (compromised with the Mrs ) and walked up Beacon Batch.

    There was a bit of sleet mixed in with the rain confirmed by a windscreen splodge test on the way there and then had a minute long ice pellet/soft hail shower of some sort, but that was all I got to see. Great views nonetheless and would definitely be amazing on a clear summer day.

    Day 2 Convective Outlook

    VALID 06:00 UTC Sat 26 May 2018 - 05:59 UTC Sun 27 May 2018 

    ISSUED 22:40 UTC Fri 25 May 2018

    ISSUED BY: Dan

    Plume events are often fraught with uncertainty, primarily due to poor NWP modelling of deep convection generated by mid-level instability. In these types of situations, including today, it is best to take a broad-brush approach and try to highlight trends, rather than specifics - basically, expect the unexpected! The latest model guidance is much further north and a lot quicker with developments than data had been suggesting just 12 hours ago. It is likely some areas within the SLGT could remain lightning free, and the forecast may need to be altered if confidence improves - it rarely goes to plan...

     
    There are reasonable signs for an area of elevated convection to be drifting across S / SE England at the beginning of this forecast period, continuing to move NW-wards through Saturday morning. Questionable as to how much lightning there will be with this activity given weakening instability, though forecast profiles do suggest some reasonable shear to help with some organisation. Either way, whatever activity there is will likely weaken with time as it continues to migrate across the Midlands and into Wales.
    A secondary pulse of elevated convection may develop and move NW-wards across SW England late morning into the afternoon, which would have a better chance of producing lightning - but this is a weaker signal amongst model guidance.
     
    This then leaves a window of opportunity during the afternoon for surface-based thunderstorms to occur. However, the atmosphere will be largely capped by a warm nose at 850-900mb, and so despite increasing instability it is possible very little will actually develop. Greatest potential perhaps across Dorset, Somerset and Gloucestershire, but this very much dependent on enough surface heating to break the cap, which is uncertain due to the potential for extensive mid/upper level cloud associated with earlier elevated convection. Should an isolated thunderstorm develop, it may be severe, capable of producing hail up to 2.0cm in diameter and localised surface water flooding.
     
    The potential for thunderstorms then increases during Saturday evening and night, with numerous elevated thunderstorms likely to develop over the English Channel containing frequent lightning and perhaps some hail. The vast majority of model guidance would suggest thunderstorms will move to the NW, putting SW England and the West Country at greatest risk, broadly Isle of Wight westwards. However, ECMWF has been very consistent over several runs (now joined by 12z EURO4) to produce a much more bifurcated flow, which would then take a very active cluster of thunderstorms NE-wards over Hampshire, Sussex and towards the London area by the early hours of Sunday.
    Given the large spread of possible areas affected, it is difficult to pin down a MDT area with any significant confidence - though worth stressing the ECMWF (and EURO4) tends to have a good handle of elevated convection, and its consistent signal over multiple runs is somewhat reassuring. As a result, have followed these trends for the MDT - though if other models are correct, this may need shifting westwards to cover more of Devon and Cornwall.

    Hmm methinks it's a scare... radar is empty, prognosis forecasts suggested something over Cornwall/Devon earlier but looks to have faded...

    It's still overcast, and scrambled it's way to the heady heights of 11.8°C ....should be ashamed of itself, naff really..

    Yes just been thinking that myself wondering where tf these showers were going to be coming from! Overcast/dull/grey/boring here for what seems like day 200

    Cab see why if you've been stuck under the rain that arrived here a couple of hours ago as it's not exactly light rain. 

    I think the Met nailed their warning to be honest, we’ve been under the rain since about 12 I think and we’re just on the edge of it for a good few hours, places to the west of me have been sat under the heavy rain all day so they must be saturated!
