  1. Long term viewer of this site and thanks for the great content. This is meant as a fun and hopefully informative thread to see to apprepciate some storms that may not be that well known. Perhaps even historical. I'll start with one from 1994. For those that haven't seen this, it's a fantastic delve into the past for what I believe was the mesocyclone on June 24th 1994. I remember this storm rolling into North London at around 7pm. A lightshow to remember! and part two being this...Notice how dark it becomes
  2. The Spanish met service have named the low pressure system for the end of this week Miguel Miguel will bring heavy rain to the UK through Friday and Saturday
  3. Storm & Convective Forecast Issued 2018-08-06 21:33:50 Valid: 07/08/2018 00z to 08/08/2018 00z THUNDERSTORM OUTLOOK - TUESDAY 7TH AUGUST 2018 Synopsis North Atlantic upper trough will begin to amplify S and SE across the far west of Britain during Tuesday, with a strengthening upper flow across the UK – as SWly jet stream shifts S and E across the UK. Ahead of the jet streak, a weak surface cold front will progress slowly east, to lie North York Moors - West Sussex by 00z Weds. A very hot, humid and increasingly unstable airmass ahead of the cold front across SE England and East Anglia is forecast to destabilise and produce thunderstorms in the evening here before the front clears through and introduces cooler and more stable air. … SE ENGLAND and E ANGLIA … Surface-based CAPE will build up through the day due to surface heating of humid plume in conjunction with lapse rates steepening in association with advection north of EML (elevated mixed layer) aloft. However, this surface instability is likely to remain capped. However, a shortwave in the strengthening flow aloft will move NE from Bay of Biscay area in the morning crossing NW France in the afternoon. The increased lift by the shortwave along NW edge of hot and humid plume over France and SE UK combined with increasing mid-level instability as dry air intrusion punches NE overlapping plume, is forecast by many models to break out thunderstorms across Brittany and Normandy by early evening, before spreading / expanding NE across SE England then East Anglia through the evening. Thunderstorms are likely to be elevated, though 40-50 knots of 0-6km shear forecast will allow storm organisation into clusters, perhaps even an MCS passing over parts of Kent and eastern E Anglia, so there is potential for strong storms that may bring locally intense downpours leading to flash-flooding, isolated hail, strong wind gusts and frequent cloud-to-ground lightning. These storms should clear away NE into the North Sea after midnight. Issued by: Nick Finnis

  5. A new thread for all things convective around the UK going into the summer of 2018. Old thread here: Convective weather relating to Europe should go into here: A chance of a few thunderstorms this week with central and southern parts of England and Wales looking most at risk. Although Monday is now moving into the reliable timeframe it is still too early to discuss specifics for the week as a whole. It is likely though that this week will provide some thundery showers or storms for a few of us. An easterly flow will probably favour more western areas for home grown storms, but elevated storms from the continent could also affect southern and south-eastern areas at times.
  6. Hello everyone, I've just introduced this new topic about Greece. As you may know Greece doesn't mean just sun, fair weather and beaches. Furthermore, the very complicated orography can affect the weather from a place to another even if the distance is just a few Kilometers. So, I will use this topic to prove what I said . Of course, if anyone has any comments, queries or even matterial from Greece, he/she can upload.
  7. Just found one I snapped in Canada a few years ago that was building into a nice thunderstorm
  8. I've just been looking through the lightning archive and I have been absolutely amazed at how much lightning has been recorded throughout this month so far. Every day so far, except for the 21st has recorded lightning somewhere in the UK, mainly in Scotland and Northern England. It really makes me think... has the UK just had one of it's most thundery Decembers on record? The dates that really caught my eye were the 7th, 10th, 11th and 19th (all pictured below).
  9. Please carry on here folks. Such boring weather we are having at the moment Lol. Let's hope tomorrow delivers something. Looking good for some if I must say.
  10. Yes I know it's only mid-April, but I think it's a good time to start asking "what do you want for summer" as late April and May can often be quite summery. You can select more than one option in the poll, just in case you want a few weather types. For example, I chosen heatwaves and thunderstorms - 'cause let's face it, it's what a summer should be!
  11. Wow!! look at the potential for this weekend and next week I really hope this comes off for us all. Please please let there be no downgrades lol. Anyway, please carry on here as you were.
  12. Here is a selection of wild weather photos that I have collected from the web. The thread gallery here contains almost 70 incredible photos. Apart from an amazing gallery of photos the question is are these severe weather events around the world becoming more extreme, not only this but are they becoming more frequent? (Have placed each image onto a same size background to enable easy viewing without size changing) Gallery: === === === === === ------
  13. A new thread here for the rest of Autumn. Autumn has been very good for storms this year! although sadly not everybody has had one yet. One rumble of thunder and one flash of lightning so far this year for me which I'm most grateful for . I am certainly not giving up any hope just yet as we all know storms can happen anytime of the year. Anyway good luck again all and don't forget to post up any pics and videos you have.
  14. New thread here. Some have been lucky and some haven't. Not one rumble of thunder for me so far this year!! but there's still time. Thanks for all your reports, pics and videos. Please carry on here.....
