I've probably missed something, but what on earth does 'Zak M's supervision' mean? 😆

In the summer it became an in joke, but basically he is in a good spot to see distant lightning in a few directions.

Stonking day for storms. Had two cells with continuous thunder [but mostly no visible lightning again]. Here's some pictures of one storm that I tracked as it progressed up the M11 which produced some

Am enjoying a weekend away 60 miles S of Prague in the pretty town of Písek, the storm front that came in this evening was dramatic! 

Didn’t know we was expecting an avalanche today 🤔

How have you missed that it's Zak M seem's to see storms every hour ask him yourself about his supervision.

Ah yes, I'm of course aware of that in-joke, just hadn't seen it referred to as 'supervison' before haha. In the context of your posts it sounded like Zak was acting as some kind of forum moderator for your posts Xander 😂

Looks like there's a bit of a squall line forming, just north of Manchester and Liverpool, things might be about to get a bit exciting around these parts. 😃  (Better than the constant rainy drizzle murk we've had all day so far. 😛 )

Day 1 Convective Outlook

VALID 06:00 UTC Wed 02 Dec 2020 - 05:59 UTC Thu 03 Dec 2020

ISSUED 09:14 UTC Wed 02 Dec 2020

ISSUED BY: Dan

Frequent showers, initially over northern and western Scotland, will gradually extend in coverage southwards through Wednesday and Wednesday night. A few sporadic lightning strikes will be possible, more especially near coasts, with the greatest risk considered in northern and western Scotland (15-20% chance). Many showers will contain hail, and will turn increasingly wintry with time.

WWW.CONVECTIVEWEATHER.CO.UK

Forecasting thunderstorms and severe convective weather across the British Isles and Ireland for up to the next 5 days.

According to the BBC, residents of Edinburgh were woken by the sounds of explosions at 5am this morning which turned out to be thundersnow.

Sorry had to laugh lol. An explosion, must have been a positive strike. Had one here a few years back now, in a winter shower, loudest thunder I ever heard. Sounds like it was Edinburgh's turn.

Just had several loud claps of thunder with nearby lightning. This is the third night in a row here that there has been thunder with heavy rain tonight, sleet last night and snow the night before. Very unusual to have three consecutive nights of thunder here at any time of year, never mind December!

I was watching the news earlier and a weatherman(can't remember his name) explained why the thunder is louder when it is snowing

in summer the thunderstorms/clouds are a lot higher up because of the heat and hence you don't hear the thunder as loud unless it is a positive cg strike of course

in winter the cloudbase is much lower,it makes sense really that you heard loud thunder and them in  Edinburgh this morning.

Britain's Wildest Weather 2020 is on Ch 4 tonight at 8.30pm. Should be worth watching. 

Usual scenes of 'record' rainfall, wind, heat.... but interesting to watch, particularly the effects of the two named storms early in the year and the devastation caused to wildlife by the fires in parts of the South East of England during the first lockdown.

Day 1 Convective Outlook

VALID 06:00 UTC Sun 13 Dec 2020 - 05:59 UTC Mon 14 Dec 2020

ISSUED 08:30 UTC Sun 13 Dec 2020

ISSUED BY: Dan

Outbreaks of rain will spread erratically northeastwards across the British Isles as a frontal system arrives from the Atlantic. Behind, cold air aloft with reasonably-steep mid-level lapse rates will overspread relatively warm SSTs to generate a few hundred J/kg CAPE over open waters and coastal districts in the west. Therefore, scattered showers become increasingly likely, initially over Ireland during Sunday afternoon before the risk expands eastwards across Britain through the evening and night, and these will become organised into discrete bands as one or more shortwave troughs swing through the in the broad southwesterly flow aloft. Given the strongly-sheared environment, some line segments will be possible at times with perhaps a low-topped supercell, capable of producing squally winds and the risk of an isolated tornado. The risk of sporadic lightning is greatest near western coasts, and so particular attention is given to the Irish Sea into parts of Wales, NW England and SW Scotland - however the coverage of lightning is not expected to be significant enough to warrant a SLGT.
