LET IT SNOW AND BE COLD!!!***RAMPING THREAD***Mod Note #1193#2705

Just out of curiosity, which is more severe, the Arctic Chill or the Siberian winds? I'm guessing Siberian because it goes over the land, picking up colder weather along the way whereas the Arctic chill goes over the ocean where the temperatures are above 0. Is that correct?

I would think the Siberian would be colder too, unfortunately its almost 26 years since we've had a genuine easterly blast. I remember the extraordinary cold spell of Jan 87 with daytime temps of around -5c and a gale blowing - a real penetrating pipe burster! There must have been about 25cms of snow along the east coast. It only last about 3 or 4 days though - I'm still waiting for another one!!

1. Use m.boards.ie and not touch.boards.ie this will not pull in graphics and eat data allowances.
2. Thats entirely your fault for going into an FI thread which is full of very graphic snowpr0n ....and also where I posted that CIE Snowplough Train vid you are complaining about.

Stay away from FI threads full of graphic snowpr0n in future...m'kay!

1. use m.boards
2. I go into FI for the charts

Show me this snowpórn you speak of!!

it can snow in december when i'm off from college and living in the city center.:D

FM104 just plonked this on Facebook.

I presume it's 100% accurate. :P

Winter forecast 2012/13

Head forecasterOctober 21, 201213

Latest UK Winter forecast 2012/13 update – 9th November 2012.
Why we expect winter 2012-13 to be a cold one.
We expect this winter to be colder than average, the general theme throughout November will be Atlantic driven weather patterns.
Late November we expect a change, a pattern that will disrupt the westerly airflow’s and block the Atlantic, with the milder zonal weather patterns at bay we will see an increasing trend of much colder air making it’s way from the north and north east.
There will be periods of high pressure bringing settled conditions with ever increasing night time frosts, becoming harsh and widespread.
As things stand we expect some significant amounts of snowfall for Scotland, Northern England along with eastern coastal counties of England as for south as the south east corner in to December.
Is there any evidence of this at such a long range out?
The jet stream is an important driver to our weather patterns here in the UK and of late it’s had a tendency to position it’s self further south than expected.
When the jet stream is positioned to the North of us during summer months the UK generally enjoys a much warmer, settled period of weather.
If the jet stream is positioned over us or to the south of us it will bring much more unsettled conditions.
During winter if the jet stream is positioned further south it leaves a wide angle of attack open in which polar maritime air can move in across the UK.
With the jet stream much further south than usual if we get a blocked pattern where the westerly airflow’s from the Atlantic become blocked this will allow weather systems and much colder air to flood from the Arctic, and from Scandinavia (the north east).
We expect the same type of pattern that we experienced in 2010, causing the coldest winter since 1978/1979. The UK national temperature data set was started in 1914, the winter of 2010 was not only the coldest in 30 years, it was also the 7th coldest winter on record and caused over £700 million pounds worth of damage.
Satellite imagery from 2010 showing the UK under widespread snow.

We expect some significant snowfall during December, certainly before the Christmas period. There has been talk from other websites about a much milder winter than average.
I wouldn’t put the winter woollies away just yet.
Our original forecast is below.
November

In to November we expect low pressure to be in charge bringing west to south westerly winds, towards the middle part of the month we expect colder air to make it’s way south.
As low pressure systems push across the United Kingdom they will drag colder air from the North at times bringing spells of wintry precipitation to Scotland and Northern hills.
There will be very little in the way of settled spells during November across the South of the UK, with milder air likely to prevail across more western and southern parts, with the coldest of the air in the North of the UK.
The orientation and angle of low pressure systems during November will fluctuate, at times bringing increasingly colder air South across the UK.
However settled spells are likely across the North, especially Scotland and far Northern England where temperatures will drop bringing widespread overnight frosts.
Rainfall will be slightly below average across the North, and above average across the South. Temperatures around average for much of the UK, slightly below for Scotland and the North of England.
December

A repeat of December 2010?
December is going to be a mixed month, fairly mild to start, the theme will change later on in the month with North Easterly to easterly winds bringing wintry showers and snow showers to much of Scotland, Northern England, and eastern coastal counties.
For a sustained period of cold weather for the UK the general idea is to block the Atlantic and it’s low pressure systems. If you get the perfect setup the flood gates can open allowing much colder air from the East like December 2010, or from the North of North East.
We expect December to be a rather cold month with snow showers for many, with overnight temperatures dipping well below freezing.
Rainfall will be average to slightly above average.
January

We expect January to be slightly milder at first, then cooling down during the second half of the period leading in to a very cold February.
Cold air from the North East will bring periods of snowfall to much of Northern England, Eastern coastal areas of England and filter inland.
The South East and East Anglia may receive some very heavy snowfall.
Conclusion
I think this winter will be average to slightly above average in terms of snowfall.
There is the potential with certain weather patterns and signals showing a colder than average winter, this winter may surprise quite a few of us, and who knows it only takes 3 weeks or so of widespread sub zero temperatures and snowfall to equal that of December 2010.

I do like cold and frosty weather, it beats the wet wet wet we've seen this year but NO, it has to be below freezing and very snow, nothing is more prettier. That way you get the lakes freeze up and the icicles and plus the cold means the snow will stick around longer than usual. Frost isn't much of an adventure. But the snow is, it makes doing most things a challenge which is fun.

Besides you can only build igloos, have snow ball fights, sled and hike in a white out in the snow... I can't do none of that in the frost. Also its nice to have a snow day off, wont get a snow day without snow!

What gets me with gritting and plowing primary routes is they seem to totally forget secondary routes which makes it near or imposable to get to the primary routes.on that note i checked my local Co Council gritting route and my village is not on it

What link is that ? It would be handy to know .

supposed to be 14 degrees on Tuesday! what a let down this winter is going to be..

Relax, we're only 11 days into the season. We still have another two and half months left of bitterly cold weather.

As long as the pipes don't freeze I'm fine

What's this 'blocking' you're all on about?

We will end up with Easterly or North Easterly winds from the continent = snow
