During straight N'erlies by the time the arctic air has reached the South coast it has usually lost most of it's moisture, which is not so good in a showery airstream inland as showers will tend to die out before they reach S Central England, the so called 'wishbone effect'.
But on the otherhand too much moisture at lower levels in marginal situations mean that snow may melt in the lower layers before it reaches the ground - this can often be the case near N/NW/NE facing coasts in a N'erly where troughs/fronts otherwise brings snow further inland to many areas - this was the case in the 28th Jan '04 event I believe where the air ended up being to moist in the NW/W coastal areas due to SSTs warming a shallow layer of the pA air as it crossed the sea.
acorrding to net-weathers forecast i have snow for friday into saturday its looking great i just hope that stays the same its been saying that for the past 2 days so fingers crossed.
what do you reckon our chances of having 2 days of snow are nick ???

If I'm reading the 06z GFS correctly, somewhere in the south (Southern England or South Wales and particularly higher parts like the Mendip Hills for instance) could have 48 hours of snow between next Friday and Sunday. That Low Pressure is over the top of these areas on many of the 6-hourly charts on these days.
well i hope that comes over the centre of england and sheffield where i am and gives us 48 hours of snow that would be amazing would probably end up with over a foot +

gutted i fell asleep and missed the countryfile forecast did they mention anything about snow in central areas around sheffield etc.

Livingstone warns of coldest season since 1963
By Michael McCarthy and James Burleigh
Published: 22 October 2005
Predictions of a freezing winter have been based on a weather phenomenon known as the North Atlantic Oscillation (NAO), which is the difference in atmospheric pressure between the Azores and Iceland.
When pressure is low over Iceland and high over the Azores, westerly winds sweep across the Atlantic and give Britain a warm and wet winter. But if Iceland's pressure rises and that of the Azores dips, we catch cold air from the Continent.
Over the past 54 years, scientists have observed that when the NAO was in a particular state in May, a very cold winter often followed in Britain. A high-pressure system tended to block the prevailing warm moist airflow from the west, allowing cold air from the north and east to cover the country.
The Met Office spotted signs of the NAO pattern in May, when areas of unusually cool water appeared in several places in the Atlantic - these kinds of sea temperatures are thought to contribute to the NAO effect.
Richard Graham, from the Met Office's seasonal forecasting unit, said: "We get the sign of the NAO correct in two years out of three, and it has worked for more than 50 years of data."
Ewen McCallum, chief meteorologist at the Met Office, said there is the potential for long periodsof up to two weeks "where the temperature may not rise much above freezing".
Mayor of London Ken Livingstone warned that London and the South-east could face the worst winter since 1962-63, when Britain was frozen from Boxing Day until April with an average temperature of 0.2C (32.3F). He said: "We could see quite severe loss of life."

and flagpole if your going to say something at least state you points as to why it might not happen not come out with a coment like whatever.

this is amazing if it does come of spirit of 1740 posted this on uk weatherworld
what would happen to the uk if it did come of we would have some serious chaos. Article due in The Sunday Telegraph will apparently say that there is now a 50% probability that this winter will be colder than 1947 and 1963 - and by implication the coldest since 1740.
I hope the next upate say a 50% probability of being coldest since 1684 and then the next update much colder than 1684.
-
the temps are up and down like yo yo's at the moment cant be too long now till we see sub zero tempretures pushing towards moscow surely.
-
oslo is forecast temps as low as 2c so that is good news as well.
-
thanx for the updates timmy
i was looking at ceefax earlier it says on thursday oslo will have a max of just 2c http://nwstatic.co.uk/forum/public/style_emoticons/<#EMO_DIR#>/laugh.gif http://nwstatic.co.uk/forum/public/style_emoticons/<#EMO_DIR#>/dry.gif which will come as a shock to the system.
and moscow will drop to 5c on thursday as well so the cooling of europe looks very rapid indeed.

Ooooh Agh DL you saucy thing, wish I hadn't asked now
Though the cold pooling still appears to be growing I'm concerned that the pesky warmth due to be pumped north over the weekend and into next week might start to undo all the good work from Sept and early Oct.
As for the article, sounds like a typical bit of crap journalism to me - The Sun by any chance?
. They could and should have said that whilst some people were sunbathing across Central England yesterday snow was falling in Central Scotland.Joy
<{POST_SNAPBACK}>
It said that in the daily mirror as well.
-
welcome joy i am not sure if 69 has gone but if you wanted the 69 im sure some one could give you it
:lol: back on topic now the cold pooling looks as if its continuing to grow just hope it carries on that way to be honest then hopefully we will get a good start to winter.
i was reading an article ysterday about this week it was saying how people where sunbathing yesterday but its going to come to an end at the weekend with snow probable in scotland.
-
You probably get more in one november fall than i've seen cumulatively in 9 years.
<{POST_SNAPBACK}>
i live on highish ground really though thats why i saw 10cm last november aroun the 19th i think it was was really good fall of snow and in feb we saw about 20cm of snow in that massive storm yet up the road about350-400m had about a ft of snow and about 8ft snow drifts blocking the roads in and out of the peak district.
-
there looks quite alot of activity in the tropical areas of africa that could spell bad news for america if one of these form as a hurrican and smash into new orleans galveston etc.
-
http://nwstatic.co.uk/forum/public/style_emoticons/<#EMO_DIR#>/dry.gif above 20c again if it carrys on that way the cet in warsaw will be at a all time high http://nwstatic.co.uk/forum/public/style_emoticons/<#EMO_DIR#>/ohmy.gif
-
well hopefully the cold pool will grow and the temps cool off,and then for some cold fronts to down here from the north i think its abit early to say the least about snow anyways maybe mid to late november again thats when i think we will see some decent falls of snow.
-
the charts dont look to impressive at the moment just hope this all changes as we go in to november so we get loads of snow.
-
just hopeing now that all of this does not go pear shaped now as per usual it always happens in this country hopefully the cold pooling will continue to grow not dissapate
-
well i seem to think think the cold pool will grow as well as a few of you have mentioned, as a few people have said this is the most potent its ever been so we could be in for some real winter weather if the cold pooling continues to grow i just hope the greens and yellows get replaced by blues in the mid atlantic then that would ease any doubts.
-
we see lying snow almost every year in march here in sheffield i live on high ground basically so that should explain most of it.
-
Wow, I dont think I have ever seen snow like that in my life time!
Thanks for sharing the photos, I had forgotten what great fashion we had back in the 70's
<{POST_SNAPBACK}>
oh i have i saw a ft of snow a couple of miles up the road from me on the moor at around 350m asl there was snow drifts of about 7ft and blowing snow was blocking alll the main routes from sheffield to the peak district.

well all that could change by friday we just have to wait and see as usual hopefully we will bare the brunt of it in sheffield come friday i can only hope
