    The GFS op and control run are run at a higher resolution than the other GEFS members,so in theory they should verify better.

    I don't believe that this is correct.

    As I understand it, the op is run at a high resolution and the control at a lower resolution.

    The 'GEFS members' are run with slightly adjusted starting data (and also at a lower resolution).

    Oh Deary me! - I thought it might after things started badly with less amplification on the UKMO and now its continued on to the ECM.

    I wouldn't worry about output from UKMO and ECM - they'll surely fall into line with this morning's stellar output from the GFS!

    I don't think much has really changed. The 12z is just showing a colder run in fantasy land; it has no more chance of occurring than the mild weather being shown on the 6z.

    Personally think we will see a West based NAO and average conditions in the UK with fronts crossing from the SW.

    Boo hoo, you sound of reason you!

  4. Meanwhile, on holiday in Greece...

    It started overhead but kicked off on the mainland - just the most amazing lightshow, huge forks coming down all over the place!  Still going on in the distance - can still see forks coming down well inland in the Peloponnese. 

    Good luck back in Blighty this week folks.

    God how I wish I had the money to spend my summers chasing these hot weather beasts in the Mediterranean - what a life that would be!

    This is from UK Weather Scientific who used to be Met Monkey I think? What are thoughts on this? 

    DANGEROUS THUNDERSTORM STATEMENT for Wednesday 21st June 2017 from 15:00 until 06.00am Thursday 22nd for the potential of dangerous supercells. 

    There is a risk of dangerous supercells developing today across Northern England, North East England (Newcastle) and surrounding areas with a slightly lower risk for the Midlands.  The situation is highly complex and a little uncertain due to the number of potential limiting factors however it is expected that a few supercell thunderstorms exhibiting rotation will form later this evening (dependant on heat and trigger locally).

    Thunderstorms that develop in conditions present today will be capable of producing large or very large damaging hail, damaging straight line winds and moderate strength tornadoes, not too dissimilar to those that form in the states. In addition usual severe characteristics typical with storms such as frequent lightning and flash flooding will be observed. 

    Severe thunderstorms are also possible across the N Midlands and into E Anglia although the threat is more uncertain and isolated due to the presence of upper ridging drying out the vertical profile. Nevertheless any storm that does manage to fire will most certainly become severe and dangerous. 

    It must be stressed that any storm that does develop today will need extremely close monitoring and we advise the public to be very weather aware and on high alert. The main risk is considered to be later this afternoon with focus more on the evening when heat and cap breaking is most probable. Please share this post with as many people as possible and rest assured through the day further updates will be provided. A potentially dangerous day of weather locally. As is always the case with set ups like these many places will remain dry or could miss the core of any storms but regardless the violent nature of today's storm potential warrants utmost vigilance and awareness. Stay aware and stay safe.

     

    I used to be a member of Met Monkey.  I get what people saying about hyperbole but in my experience Keithy Joe has a particularly good understanding and track record of forecasting thunderstorm events, so whilst I understand what people are saying I also note with interest Keithy Joe's thoughts on the situation.

    Let's not forget that in recent years there have been some tragic incidents involving young children where bouncy castles have been taken high into the air by sudden gusts of wind.  Maybe it's not such a bad idea to make people vigilant where the POTENTIAL is as severe as perhaps it is today?

    Really? I've seen a few things on the internet recently saying similar and even (non weather nut friends and family are noticing)but nothing official, I'd be really interested to see that. 

    Bizarre last night as although the action was mainly Kent/channel way we got a few strikes around here about 1 every 5-10 mins in the end - just as I went to bed the closest lightning strike I've ever experienced hit somewhere near by. A flash and massive explosion at the exact same time had me 6 feet in the air and out of bed- i was sure the house had been hit!! Kind of makes up for not seeing the main action but very scary. Just wish I'd managed to actually see/film the bolt!
