Looks to be more tomorrow, now who's going to strike lucky tomorrow It's a shame I have nothing here tonight as the convection is awesome. Anyway, here's hoping to read some great reports and don't forget your pics and videos which are most appreciated Good luck everyone -

As the title, Lightning storm with no thunder in West Lothian on 14.12.13, watched this from Polbeth around midnight - 1am (sunday)... at first thought it was a powerline sparking in the distance (till my girlfriend said there are none over that way), but at one point the entire room lit up, so it was real close... it then moved off towards Livingston. All of this happend with not one sound of thunder at all, I was amazed by it, and eventually told to; 'get away from the window and sit down, its late'.Still don't understand it. Weird weekend, saw 4 shooting stars over Friday / Satruday too... same place, but once in Edinburgh. Anyways, anyone else see this, or understand why? (I saw an old post after a google search that took me here, but post was archieved).- 10 replies

Please let me know what you think and thank you for letting me share this rare moment with you! (we dont get electrical storms very often anymore around here) Thanks again! unthrown

Never a good time to start a new thread, the old one was creaking a bit though! Please continue your convective storm chat, observations, opinions and forecasts here please! Old 'fred' here: http://forum.netweather.tv/topic/77030-convective-storm-risk-discussion-21st-june-2013-onwards -
Here's a brand new thread for Autumn onwards and there's even a little potential for something tomorrow folks. . DISCUSSION British Isles, France A warm and moist maritime air mass is situated across the Atlantic west of the Bay of Biscay. This air mass is convectively mixed and is advected north-eastwards ahead of the approaching trough. Along the axis of warm air, a well-developed low-level trough is present and will move into France and the British Isles. At the surface, backing low-level winds are indicated by latest GFS model across southern France and the British Isles, leading to low-level convergence. A weak mid-level trough will also lead to some QG forcing. Daytime heating will result in weak instability across France. Instability over the British Isles is questionable, but elevated CAPE is likely given the well-mixed air mass. Given the lift along the trough axis and low-level convergence, at lead weak CAPE is likely. Together with CAPE and forcing, low-level vertical wind shear is expected to be around 10 m/s in the lowest km and low-level hodographs are rather large across the British Isles. Current thinking is that tornadoes can develop in this environment. Given the weak instability, chance of tornadoes seems to be too low for a level 1 forecast. Stronger storms may also produce excessive precipitation. Otherwise, severe storms are not expected across the Birtish Isles and France. http://www.estofex.org/

Has anybody ever experienced this weather Phenomena at all.? I know I haven't had the pleasure, maybe one day eh! Thundersnow, also known as a winter thunderstorm or a thunder snowstorm, is a relatively rare kind of thunderstorm with snow falling as the primary precipitation instead of rain. It typically falls in regions of strong upward motion within the cold sector of an extratropical cyclone. Thermodynamically, it is not different from any other type of thunderstorms but the top of the cumulonimbus are usually quite low. http://en.wikipedia.org/wiki/Thundersnow Typically, a thundersnow event occurs with the majority meteorological recipe coming from a thunderstorm forming over a body of water. When the colder air from a normal winter front collides with the warmer air over the water--you're likely to get heavy snow and thunder clapping concurrently. But it isn't just that cut and dry and harmless. All the variations involved in thundersnow make it frequently dangerous if you're caught out outdoors when it happens. Some of the examples of what thundersnow can do based on recorded bizarre weather events in history: When thundersnow happened, strangely, in New Mexico once during the late 90's--a ski lift at a ski resort was hit by lightning and heavily damaged. In one of the interesting variations--snow fell as ice pellets. These ice pellets are frequently are larger than typical hail...hence causing more injury if you happen to be outdoors with no undercover areas within sight. Buffalo, NY (during one of their massive snowstorms in 2006) reported a heavy thundersnow event that went on for hours. It's said that it's one of the longest reported thundersnow events in weather-recording history. People reported heavy snow falling with heavy claps of thunder and lightning strikes all through the night and day. This seems to give the indication that thundersnow can turn into a circular and prolonged storm if the conditions are just right. Please discuss:

Carry on your discussion here folks. Let's hope we see a few more out of the NSC tomorrow.Good luck y'all Now let's chase those storms

Well folks, looks like there could be a lot of fireworks in the coming days and not just for the 4th July ! So here's a new thread to start the ball rolling and I wish you loads of luck .. Also if like me, you don't get your storm then please head over to the 'No storms club' where you can rant and rave as much as you want! Now let's keep this thread cheerful as there's some good storm potential to look forward to. Keep safe and enjoy.

WOW what a day guys!! In a word........... SPECTACULAR Thanks to everyone for your input into the forum today, all the reports, pictures and footage has been fantastic Please continue discussing any further convective prospects for the UK in the near future...... Todays events sure will be hard to beat!! We have a thread running to discuss todays awesome weather events and you can also add photos or any video footage you may have, right here >>>> http://forum.netweat...ootage-2862012/ <<< Liam

Ok folks, you asked for it! here's a new thread. Now get your happy hats on lol and join in the happy discussion of what may lie ahead... Yay lolAnd for some reason if the storms disappoint or let you down head over to the No Storms Club for a good moan OK

Now, I know that if a storm is directly overhead, the thunder will follow the lightning almost instantly. But, once or twice I have seen (and heard) when there is a very, very vivid and bright flash then a few seconds later it will be followed by an ear splitting crash. So, if the storm is overhead as I reckon it must be because of the loud crack and brightness of the lightning, why the gap of those few (I've counted 5/6 ) seconds. Just curious and I'd like to understand. Thanks, Jess.

Does anyone know of any instances in the UK where sea breeze initiated storms have occurred? They occur almost daily during the wet season in Florida where the two sea breezes from the Atlantic and the Gulf of Mexico converge in the middle of the state bringing spectacular thunderstorms. Polk County gets around 25 storms a month in June, July and August. Further convergence areas are then set up by thunderstorm outflows, allowing the storms to rumble on into the night even after the sea breeze dies out. A similar effect occurs in Cuba where the sea breeze from the north meets the sea breeze from the south, although it is less pronounced than in Florida. I also believe it can occur in Italy from time to time. As the UK is also quite narrow I wonder if its possible for a westerly sea breeze to meet an easterly sea breeze to bring thunderstorms? In Florida it usually only occurs from May to September as the sea surface temperatures are in the low 30s, and the temperatures over land need to be higher than this for a sea breeze to set up, but the seas around the UK are far cooler, so sea breezes can more easily affect the UK. If anyone knows of an example of a sea breeze thunderstorm outbreak in the UK I'd very grateful if they could let me know when it happened! I have attached a diagram I found which outlines the phenomenon quite well:
