With winter now firmly in its grip here in the UK, i think it would be prudent to inform our UK members (particularly those living north of Manchester) of an up-coming major storm for Friday 9th December into Saturday 10th December.

Before i provide a synopsis of the event, i want you all to know that this is not a "normal" winter storm, this is a very deep storm, this storm will present a danger to life in more than 1 way.



A very strong jet stream running across the North Atlantic towards NW Europe over the next few days, driven by a steep thermal gradient, will rapidly deepen a low pressure system moving NE which will track close to northern Scotland on Thursday, by then a very deep depression with a low central pressure.

Although the exact track of this low is still not certain, strong model agreement today brings the centre of this deep depression northeast across the northernmost part of mainland Scotland during Thursday afternoon, with a risk of very strong and damaging winds possible across Scotland during the day -particularly western areas, the central belt and across to the northeast, where wind gusts may reach 80-90mph with isolated gusts of 100mph not out of the question. Further south, severe gales are also likely across Northern Ireland , northern and (parts of) eastern England - with gusts of 60-70mph likely with isolated gusts of up to 80 mph in exposed locations. Therefore the public are advised to expect travel disruption across northern Britain on Thursday, with a risk of damage to buildings and trees.

Also winds will veer northwesterly on Thursday afternoon, which will bring colder air with sleet and snow showers southeast across Scotland, Northern Ireland, NW England, Wales and later across The Midlands. Heavy snow is possible from these showers, which may bring significant accumulations across western areas with a risk of drifting in the strong winds, therefore there is also a risk of travel disruption from snow later on Thursday and through into Friday morning.

As the severe gale or storm force northwesterly winds transfer out into the North Sea Thursday night and Friday morning, there is also a risk of a storm surge heading down the North Sea which could bring a risk of coastal flooding as high winds and very low air pressure coincide with high tides


This storm will present danger to life through many factors. There will be a storm surge alone the East Coast of the UK, there will be winds possibly in excess of 100mph for northern Britain, there will be blizzards and a projected wind chill factor of below -15oC.

Since this is the festive season and there are a lot of Christmas Work Night Outs, if any of you are out and about...please wrap up warm. Don't be foolish with the short skirts and flimsy jackets.

This is a very dangerous storm and for those of you living north of Manchester, make sure you are prepared for power cuts and any structural damage.

As a side note. I am an avid weather fanatic and i don't scaremonger people about weather events. This is a real event that is serious in nature.

Be Safe...

I do have synoptic charts and data graphs that i can post on this event if any of you wish to see them but using the image facility on ATS is dreadful. If anyone wants to see any of the images and model projections, let me know and i'll try to figure this out.

(There is no conspiracy here, this isn't HARRP or Chemtrails or Aliens or David Cameron, this is a notice for safety and advice that anyone wishes to share)

ETA: Here is a link to a map of the surface temperature and the wind speeds projected here

Here are a few images to help illustrate so more details. This is what your not being informed about at present, this is what the models are predicting. The Met and BBC will hold off as long as possible before upgrading their warnings, but this is some of the images they use.



The image above illustrates the isobar chart and the severity of wind in knots. the maximum projected wind speeds are about 75-80knots which i believe is about 90mph. The isobars are closely packed with a N-NW direction of wind. As you can see, the storm surge will most likely stretch down the entire East Coast.



This image also shows you pressure systems, this time on a global scale. As you can see we have our projected one right over the North of the UK with winds heading straight from the an Arctic region



This image shows you the pressure and the temperature of the atmosphere at a height of around 18,000ft. So bearing in mind that the UK will be experiencing a very cold airflow of approximately -40oC at a height of 18,000ft.

ETA:


The above image is showing the LP system valid for Friday just East of NE Scotland, but whats worth noticing is the other LP system flowing out of Greenland. This other LP system is worse than the one we are about to experience so for those of you who think this will be all over by Saturday...it may well be only a lull in a series of major winter storms

Incredible. Are there any other sources available, or are the meteorologists just now releasing this data?

My advice is to keep a check on any of your elderly neighbors. Many will be having to divide their small pensions on expensive heating and rising food prices.

2012?
It's okay we've got another year...


Seriously though, cheers for the heads up. Time to buy some tea and scrumpets..
And make sure small one is suited and booted.

We've been looking forward to snow, but perhaps not THAT much..

Well being down south, we do tend to miss out on most of the harshest weather in the UK. Most of my family are from Manchester and to be honest whenever I visit it always feels a couple of degrees cooler and normally raining. But your a hardier bunch up north so you can handle it.

There are a few sources available for this but most of the Meteorologists wont publish too many details yet. The source i posted in the OP is a link to one of the best sources for UK weather. There is a forum there that is very active that can be browsed by guests.

The met office have a slightly different forecast. They are saying there will be 40 mph winds in the north and up to 60 in some parts of Scotland and the whole thing will start to calm down on Friday.They don't always get it right, I think the last time (this year) the met office warned about a storm for northern England it was really quite mild. Their weather warning is of ice and not wind anyway even thought it's obviously going to be gale force winds

Having said that it's good to be cautious and prepared.

The Met are not releasing further details yet because of the uncertainty, however, ALL of the models are pointing to a severe low pressure for Friday. The Met will update their site with Alerts probably later today or tomorrow.

Watch and See...

This is very good advice.

Also, when the snows calmed and people start mooching about outside going to the shops etc. If you see elderly persons struggling on the icy pavements, spare a small amount of time if you have some and ask them if they would like to be escorted.

I had an unfortunate incident that landed me in A&E two winters ago when the snow was pretty bad. There were many elderly people in there with quite severe broken bones due to slipping on ice, some screaming in pain. because the local councils were so sparce with gritting pavements.

I actually witnessed a poor old guy fall over in the ice injuring himself quite badly. People laughed. Not just kids, but adults too. Only two people went to help him and call an ambulance, myself and another lady.

Yes they seem to know vaguely what's going to happen
I suppose it could be better or worse than they
say.

The met office's warning is actually for snow, not ice, I read the symbol wrong!

Just realised I'm South of Manchester... Nottinghamshire to be precise... does that mean no snow?

Best sort out my Thermals I'm right up North on the Wall.

I guess Nedd Stark was right "Winter is Coming".
