  1. Hey guys, back from 2 weeks in the US visiting family in both Florida and Michigan. While there i was able to see some of the best convection and storms i've genuinely ever seen (photo dump incoming ) I decided to delete the previous post and put this in a new topic so I didnt clog up any actual discussions/feeds. July 20th featured an enhanced risk in Michigan, Due to bad positioning i was unable to get many pictures of the large MCS that developed producing 80 mph winds, QLCS tornadoes and quarter sized hail. However, I was able to get some shots of the storms anvils as they passed me to the North-West. Florida was much more fruitful in storm terms, delivering daily thunderstorms, heat indexes above 40°C and 23°C+ dewpoints SBCAPE was regularly in the 3000-4000 range with it reaching 5500 at one point, additionally it never went below 1000 j/kg during any of the days or nights i was there. While in South Florida near the town of Homestead I believe I was able to chase my first ever US Supercell, i'm still 50/50 if it was however radar presentation showed the storm deviating from the North West path of other storms and it began to move directly to the East. Additionally velocities showed the storm had some weak rotation in the mid levels. It was also the most electrically active storm i've ever experienced, multiple CGs in rapid succession with thunder becoming a constant, never ending low rumble in the background. I'm not sure if anyone experienced with supercell structure can help but it did have a substantial lowering on it for a good 30 mins with rising scud in the inflow region. No sign of anything tornadic but the storm did go severe warned for 30 mins. As the storm moved slowly off to the North East its Anvil was caught in one of the most amazing sunsets I've ever seen. I still can't believe i experienced this, just stunning. This happened everyday I was there as the sun set behind anvils of the daily thunderstorms. This was followed by around an hour of lightning as the storm slowly died and faded to the East, however tropical thunderstorms then rapidly developed off the south coast of the Florida Keys. With water temperatures between 31-38°C and Nightime temps never dipping below 34°C these storms were very electrically active. I will try to trim some videos of the light show and post some on here. The flight back home was pretty convective as well. Overall, an amazing trip that i'm already missing, will hopefully be able to go back soon. Hope you guys like the photos, not sure what to do about some of the weirdly cropped ones but oh well, I'll try to post some videos of those night storms if the jetlag hasn't killed me
  2. This is where you can post some of the wildest and weirdest weather phenomena.
  3. The prospect of a UK heatwave brings along excitement for me because I see high temperatures as a contributory ingredient towards a noteworthy thunderstorm. Now, given that many additional ingredients are required to aid thunderstorm development, what is the coolest day you've seen a severe thunderstorm crop up in? And no, thundersnow don't count unless it had severe elements.
  4. As I'm sure you're aware, lightning bolts can display a wide variety of colours ranging from lilac, white and blue, to even more exotic colours like yellow, orange and even green. There are many causes for this wide variety of colours. This ranges from the temperature of the lightning to atmospheric and environmental conditions, as mentioned below: Lilac/purple lightning Lilac or purple-tinted lightning is usually the most commonly observed colour. It is often caused by precipitation, so the observation of it most likely means that the thunderstorm generating it will be a high-precipitation storm. Lilac lightning is also rumoured to produce louder thunder, though this is disputed. Blue lightning Blue lightning bolts tend to be the hottest lightning bolts to occur on earth. They are also some of the more commonly observed colours (after lilac lightning). Atmospheric-wise, they maybe caused by small amounts of dust in the atmosphere. This is because these dust particles scatter the light coming from the lightning, in a similar way to how molecules in the atmosphere scatter the sun's light, making the sky also look blue. White lightning The light radiated by virtually all lightning bolts is white. This means that to observe it, the air must be free of pollutants and dust which can scatter and refract light - so essentially you're seeing the lightning with very little interference from the atmosphere. White lightning is also the some of the hottest lightning that occurs on earth (after blue lightning). Yellow lightning Yellow lightning bolts are much more uncommon and tend to be cooler than blue, white and lilac lightning bolts are. They also tend to be indicative of dry thunderstorms, so the presence of yellow-tinted lightning could mean that an approaching thunderstorm is a low-precipitation storm. Other colours Other colours of lightning have also been reported. Orange and red lightning has been observed and these bolts tend to be some of the coldest lightning. These colours also tend to be observed near the base of the lightning, as it strikes the ground. Green-tinted lightning is also occasionally seen, and this may be caused by the lightning heating up certain gases in the air, giving it a greenish tint. Well that was a bit of fulminology for you there. I hope you stuck with it, and thanks for reading.
  5. Been searching around for pictures & videos of this supercell that brought down trees near Canterbury I believe & had golf-ball sized hail? All photo links I've found for it in past forums are dead & I'm interested if anyone still has any pics of it. Thanks. Please move if I've plopped this in the wrong area!

  11. After my first trip with Netweather, storm chasing in Canada and USA, a look back at what occurs on tour. https://www.netweather.tv/weather-forecasts/news/9774-storm-chasing-in-the-usa-and-canada---my-first-experience-as-a-storm-chaser?fbclid=IwAR0M4JVIbdEE00Rc2kyYBHy_N3hW-NK0Vcmh3sp0AbxX38sgSGa39nJJSTo
  12. Greetings ^^ This is my first post ever here on this site Hope we get along well ^^ Here is some collections of videos showing a very loud thunderstorms in Kuwait Hope you enjoy it One of the videos has my lightning detector in action ^^ The third video has the lightning detector & also a lightning strike X) Reminding : At the beginning of every video is the beginning of each storm, so the thunder will get louder the more you proceed with the video Note : For better experience please wear your headphones - thanks!
  13. Hey there. In the debt-free, savings possessed-future I do fancy the idea of emigrating. Spain, albeit a cliche, will be the perfect compromise as I'm learning the lingo and it's not too far from the folks. Plus, storms potential of course Any similar thoughts?
  14. During the 28th the weather was rather humid, but there were no signs in our part of the approaching chaos that was to hit the hythe/kent area that night, even though the forecasts warned of possible storms. By late evening about 10pm, I could hear rumbles and decided to look outside to see if it was a Thunderstorm or just some old person putting the bin out. Sure enough from then on, it turned from the odd flash, to strikes and flashes every few mins. One of the most amazing storms I have ever seen in my life. What was really gutting though, was I didn't have a fully charged camera and missed out on many strikes that not only knocked our power out, but set car alarms off!
  15. Lightning from the 1st July 2015 thunderstorm from Irlam, UK
  16. Hey there. I grabbed a still from a YouTube video of a storm in Bournemouth and noticed some odd artifacts from the moment a close strike hits: Any ideas what these are? The original video is below and the screenshots were taken from 8:52. I'm sure the author won't mind me mentioning this here
  17. I'm one of those people who can feel so completely alive durng a thunderstorm but find them incredibly relaxing too. I know that people finding storms relaxin and using the sounds as sleep aids is incredibly common and I was wondering if anyone knew the science behind it?
  18. A shiny new thread as we head into the second half of July and the mid point of the summer. What a summer it has been. We started the summer with a lot of thunderstorms as June came in with a bang. Unfortunately as June came to a close and we moved into July the temperatures dropped and so did the storm risk. The most thundery early June I can remember has been balanced by the poorest early July I can remember. This looks like it is all set to change though as temperatures rise and summer returns. Temperatures are already rising across the south and this building warmth and humidity will spread northwards through the early part of the coming week, with the heat likely peaking on Tuesday. The first 30c is very likely this week. The increasing heat and humidity also looks likely, on current modelling, to culminate in the possibility of some dramatic thunderstorms. The thoughts of Weather09 in the previous thread provide a good view of what we could expect from current modelling, seen on page 140 of the thread. The very high CAPE values being modeled for Tuesday are unlikely to be realised with strong ridging. It is currently late Tuesday night into Wednesday the period of interest (subject to change of course). Pin pointing an area to be at risk at this range is pointless. I am thinking this thread is going to get busy with lots of excitement, forecasts and thoughts regarding what is likely to happen, even what you are hoping will happen. I am hoping it will be busy with lots of reports of thunderstorms and convective activity by the middle of this week and beyond. I think most of us would not want to see it fill up with "why do I always miss out", "nothing here", "wishing for no storms" or other moaning posts that should be in the correct moaning thread like the one below. Good luck to all those that want a storm. A chart showing MLCAPE for early Wednesday, just to get the excitement flowing
