Model Output Discussion 1200 hrs 15/11/14
Luke Best replied to phil nw.'s topic in Forecast Model Discussion
I'm not 100% certain but I believe different runs work on slightly different data due to some weather stations not reporting round the clock.Hopefully somebody with a little more knowledge can elaborate? -
Storm & Convective Discussion - 01/09/14 onwards

Rumbles of thunder in Totton (Southampton). Strangely the sky looks 'boring grey' like an anticyclonic winter's day. -

So, I can still hear constant thunder, but it is getting distant now. It's been constant for over an hour - top drawer! Not a single CG from that storm, at least not that I saw. Unlike the night of 17th July, the lightning wasn't very impressive today but the thunder was awesome (whereas the thunder on 17th July wasn't great). The occasional very bright flash today, presumably positive strikes, accompanied by shotgun thunder (one which had two 'booms' separated by almost a second, something I've not heard before). Nice start to the day! -

It's all going off here in Christchurch! Frequent lightning and shotgun thunder. -

Intra-cloud lightning in elevated storms - even when overhead the lightning can be miles away (vertically) and the clouds can acted as padding to 'dampen' the sound. -

Wow - just got home from 3 hours at the clifftop/Hengistbury Head. THAT. WAS. INSANE. And I agree with Luke Anthony - I'm sure I saw funnel clouds if not weak tornadoes on the back edge of that beast, lit up by lightning. And what lightning!! Never seen the like in this country. From midnight as it made landfall the lightning was literally constant and with the base being so high the CG strikes were just spectacular. What an exhilarating evening! Here's for a reload tomorrow, and good luck to all those who are still waiting.

Storm and Convective Discussion 10th June Onwards
Luke Best replied to The PIT's topic in Storms & Severe Weather
More likely of a decent thunderstorm on the Costa Brava, IMO. -

I checked the BBC graphics lunchtime on Friday and they showed pretty much exactly what happened and in the right place too. If memory serves me correctly, I seem to recall that they also predicted the convection to reach maximum intensity around 4pm which it did (although perhaps the storms reached maximum electrical intensity somewhat earlier). Having said that, the convection was probably more intense and more widespread than predicted and the movement of the showers was, initially at least, NW-SE as opposed to the forecast N-S. Overall though, it seems to have been pretty good call to me, based on those graphics alone. -
Summer 1997. I used to live in Kingston-upon-Thames and the country was enjoying a hot, settled spell of weather under an anticyclone that was sitting over the UK. 11am, and the sky was littered with fair-weather cumulus. By lunchtime these cumulus clouds were exhibiting updrafts - still small flat bases but extending vertically in a ragged manner. Then, around 3pm and quite suddenly, the sky quickly darkened and a powerful thunderstorm broke out, which rumbled on until 7pm. We had torrential rain, frequent CG lightning strikes and hail. The storm had taken forecasters completely by surprise. The radar showed a completely dry picture across the whole of the UK but with a big lump of red over our location. The TV forecast that night labelled it a "tropical downpour". It was the first time I'd ever experienced a storm in the middle of a high-pressure system (something I'd argued was impossible years before with my geography teacher) and is something I'll never forget.

Remarkably I have gone out in the garden and have seen bright flashes from what must be that cell over Reading-way! Stars above me, gentle warm breeze, a few small cumulus floating past lit up by the moonlight. -

Barely slept all night - curtains/windows open. Some some distant faint flashes to my west as the electrical activity came onshore over Weymouth but ultimately a big, big disappointment for me. Now I'm just tired and a little bit grumpy! -

Our time has come at last! Lightning cranking up on the South Coast. Just caught several fantastic strikes forking across the sky! Seems the air mass is destabilizing once again.- 1,179 replies

Luke Best replied to Jane Louise's topic in Storms & Severe Weather
Although we didn't quite cop a direct hit, watching the storm (still, over 50 miles away) is absolutely spectacular. Lightning every couple of seconds and now getting a good show of anvil lightning! One of the best storms I've experienced in a very, very long time! Reckon the A3 corridor is about to cop it. -
