Storms and Convective discussion - June 2023
Pat Butcher replied to Supacell's topic in Storms & Severe Weather
Yep, I saw the top of the cell that's over the North York Moors when sferics began around Castleford. It had a cauliflower top, and wasn't making any effort to flatten into an anvil. -

Miles off - which is a good thing, that forecast was pretty dull IMO -

Is anyone else quite surprised at the squall that's popped up around Shrewsbury? -

Fairly optimistic - the cold front is slightly slower than forecast, and the Met Office have extended their warning area westwards towards Manchester. East of the Pennines plausibly looks in the firing line. -

Probably many lightning strikes over Blaenau Ffestiniog. At 10ish miles away, the middling frequencies that give the thunderclap definition are rather attenuated, and the low frequencies are probably smeared together by reverberation off the mountains. -

UK weather warnings WWW.METOFFICE.GOV.UK Met Office UK weather warnings for rain, snow, wind, fog and ice. Choose your location to keep up to date with local weather warnings. Surprisey thunderstorm warning from Met Office. I wonder what they're seeing that I'm not - there's no evidence of modelled precip popping up on radar so far. -
This is good news. Personally, I don't think this is a thrilling weather anomaly that will be interesting to experience - I'm in fact very anxious about it. The sooner it clears off, the better.

Model Output Discussion - Autumn arrives
Pat Butcher replied to Cheshire Freeze's topic in Forecast Model Discussion
Apologies for the newbie question - within an ensemble run, should the operational run be given more weight than its ensemble counterparts? i.e. is that extreme outlier operational run as equally 'likely' as the other ensemble runs, or is it more likely because it's the operational? -

Love it. Still FI but this feature has popped up in quite a few runs now... -

I saw that! Total FI stuff, but as I recall there was a huge MCS that engulfed most of England in that run. -

In my unprofessional opinion it's too early to tell. The models all tell a different story. In particular, the GFS varies from run to run in terms of its CIN chart. We know that capping plays a huge role in setups like this one, so it might be an on-the-day job once there's more certainty as to likely affected areas. -

Yeah that's top drawer Jamie, nice one - saves having to scrabble around these nonsense webcam sites if it all kicks off. Good luck, hope you get a pelter! -
Highly unlikely - a thunderclap is around 120dB, with 150dB required to shatter eardrums. Noise Comparisons WWW.CHEM.PURDUE.EDU Any prolonged exposure to 120dB is enough to damage hearing - the tinnitus you get after attending a loud gig is a consequence of this damage. However, the nature of the damage tends to be that it builds over time, and results in degraded hearing and tinnitus later in life, as opposed to the immediate and catastrophic impairment that you describe.

Storm Eunice - 18th February
Pat Butcher replied to Thunder and Lightning's topic in Storms & Severe Weather
Sorry mate, London or LBA? I live near LBA and it's a pretty standard Westerly gale right now - yellow warning is about bob on. -

BBC is Meteoblue, right? -

This is the same feature two hours earlier on the AROME model on Windy. Out of interest, is that abrupt 'wall' of wind and change in direction textbook sting jet? -

Crikey, this brings Northern England right into the mix during rush hour. I'd expect the Amber to run all the way up to the Borders should this become more likely. I'd put whoever you're meeting in London on notice that you may not make it if the weather's bad. I think the odds of that train service going ahead are <5% at this point. -

That's really interesting, thank you for the insight! -

I was wondering about this. I would expect that a Hebridean shepherd's cottage can withstand a lot more than a newbuild in the Fens, but is there anything codified in the building codes as to what level of resilience is standard? -
I appreciate it's not your mate's fault, but in general the blasé attitude to weather in this country is ridiculous. In my opinion, a Red warning should be grounds for all non-essential workplaces to close for the day.

This is exceptional stuff, there seems to be model agreement for 90+mph gusts too.
