Storm Eunice - 18th February
seb replied to Thunder and Lightning's topic in Storms & Severe Weather
My contact at county council level says they’re being updated by the MetO hourly and discussions about going red for the SE has been going for hours. With every update the already borderline situation gets closer to red. -

The UK mobile alerts system ( gov.uk/alerts ) was meant to launch last autumn. It now says “early 2022”. This storm could have been its first ever use. -

And here we get long lists on the radio in the morning and an email if we are lucky. -

Red warnings have been issued outside business hours before. I think the news is out there now and responsible businesses have planned ahead. It’s not like school closures for snow are announced the day before in most cases… -

Indeed. SE very much in red territory. -

Wow Icon for SE, especially South London, East Sussex and Kent. The only with up Mid 80s with a few mid 90s thrown in across the Downs. -

Eh? Speeds have nothing but increased for the SE in output over the last 24 hours. -

Laura on GMB one of the few who is doing what we should expect. -

The criteria for a red warning are these: What are the National Severe Weather Warning Service Impact tables? WWW.METOFFICE.GOV.UK Make sure you know what to do when severe weather is forecast Because we have moved from absolute windspeed being the trigger for warnings years ago and are instead using the above criteria, we could end up with a red warning area (almost) matching the current amber area because there isn't much difference between 80mph and 90mph gusts causing the impacts needed for a red warning. This is if models stay as they currently are of course. -

MetO doing exactly what is expected and noteworthy impact matrix all but guaranteeing a red once the likelihood is more certain. I can't recall the last time we had an amber warning covering that wide an area and where the matrix was already showing the highest possible impact. -

To be fair, the BBC has quite a good report up on their website but arguably not prominent enough... and the TV news are running with it as if it's just a bit of windy weather. Storm Dudley and Storm Eunice: What you need to know - BBC Weather WWW.BBC.CO.UK As the UK braces for Storms Dudley and Eunice, BBC Weather's Chris Fawkes explains more about named winter storms and their impacts. -

Unless it’s a sudden change in situation which causes immediate danger, advance warnings are updated each morning and I’m sure this is what will happen later unless the MetO see something different to all of us. Going amber for a large area doesn’t happen often but it does and that would be the right thing to do today, emphasising risk and uncertainty. The red would be issued 12-24 hours in advance once more is known about the most likely areas to be hit with wind speeds warranting red. -
Really nice big flakes, bodes well for a little later. I expect convection to kick up a notch and the streamer to move slightly more south, ending up giving a few hours of snow southeast of a line from Clacton-on-Sea > Southend > Worthing to Margate > Canterbury > Ashford > Eastbourne initially (the further west on that line, the weaker... may just be snizzle west of Tonbridge) and then transferring further south reaching Dover > Folkestone before disappearing. Maybe 3-4cm in the most favoured locations.

Imagine you’re boiling a pot of water and steam comes up. You then put a lid on and the steam can’t rise. Very simplified but same principle... we’ve got cold air at lower levels, if all went to plan the air in all levels above would get colder the higher you go and what we have at low levels could rise easily. As it stands we’ve got slightly warmer air at a certain height above, acting like the lid on the pot. This stops the rise and therefore the building up of the clouds. Edit: meant to reply to your other post.

South East and East Anglia Weather Discussion February 2021 onwards
seb replied to Blessed Weather's topic in Regional
I really don’t understand this panic and talks of the bust of the century. Layman’s terms: 1. Darcy is a low pressure system stretching from northern central Europe to the med. It’s not a storm that’s meant to hit us like system coming from the Atlantic do. It’s pumping mild air and a lot of moisture north where it meets cold air in an East > West airflow. The moist air gets stuck as it can move further north due to high pressure. 2. Our region has been sub zero since 7am and it has been snowing since. Models have been showing pretty much exactly what has happened so far, including a lack of accumulations. 3. Temps will drop to -3 this evening while snow will continue to push in from the North Sea. It will accumulate. This will continue through the night and a good part of tomorrow. 4. If we are lucky we will then see showers push in from the North Sea thanks to the Easterly flow and the warm sea. The forecast says exactly that as do the warnings. The amber only came into force this morning and doesn’t expire until noon tomorrow. Based on the drifts already happening on the Downs with some country lanes being close to impassable and those conditions bound to spread and worse, the warning is spot on. -

Winter wonderland if you don’t look at the road. Having said that, temp has just gone from +0.2 to -0.1 in the last 5 minutes and it’s starting to cover the pavement and patio slaps despite puddles. -

Every time I check different weather apps (including MetO and the text forecast) this just gets better and better. -

Not surprised by the amber warning at all. German forecasters are in panic mode about the northwestern part of the country with many comparing what is forecast to the Dec 1978 blizzard. -

Following a brief shower and a few flashes & thunder around 3:30 it's sunny in Ashford with a temperature of 26 degrees and apparently a feels like temp of 31. Positively Florida-feel. I think we are in for a few surprises in the very SE corner of the country. Regardless of modelling... it just feels like it.
