It's amazing, in that small area, church fenton to york, they have had hardly any snow melt and temperatures a good 4/5C colder than anyone else. Must be the difference a good snowpack can have on the surface temperature.
I still wonder If I'd have had 6 inches of snow like church fenton rather than the 3" I got, would temperatures have remained below zero with no snow melt?
Not sure as that area that has seen the coldest temperatures does happen to be a little frost haven in it's own right. Between Toppcliffe and Church Fenton.
Cold air trapped at surface in the Vale of York. Snow cover will help but don’t think depth will make much difference. Typical under high pressure. Not seen anything over 1C since the snow arrived.
"The vale is in the rain shadow of the Pennines so has a lower rainfall total than areas to the west. It is also subject to more fog and frosts in winter than other areas because of the tendency of cold air to drain into the vale from surrounding higher ground."

No sign of a thaw just yet here (7 miles north of York centre). was -4 @ 11am, with a low of -7 this morning.

Tree down over the River Foss in York:
"A SECTION of York city centre was closed and five parks were shut as Britain prepares to weather the worst storm in 15 years.Police cornered off part of The Pavement this morning after a branch of a tree outside St Crux Parish Hall cracked after gusts battered parts of York and officers feared it could lead to a member of the public being injured."

Thunder storm currently North East of York.

North of York we have had lightning & thunder and rain (heavy on and off) for about 3 hours. I think its about done now, with light rain and brightening skies. We also had a storm at 7am.. Been very active day here so far.

Thanks for taking the time to do this. I attempted it a while back using a very old version of photoshop... and failed.
Used Fireworks 2004 -> used two layers, blend mode set to "color" for top layer (2010).
Used Photoshop CS4 for pixel count, using histogram window to show pixels, with magic wand (Tolerance 0, anti-alias OFF, Contiguous OFF and Sample All Layers OFF.) to select colours.

Last years looks better - Iceland and Scandinavia have much more.
If I have worked this out correctly: [based on pixel count]
Last year had 3% higher snow cover at this stage:
gray = 5214
green = 5995
white = 17929
this year = 23143
last year = 23924
This year cover is 97% of last year.

Excellent thread guys, been reading for the last couple of weeks everyday watching the snow slowly get colser to us. Nice to see the snow reaching 'Lapland', my Favourite web cams are the Finnish road cams which have shown widespread snow falling over the north of Finland this week, though a serious melt happened yesterday afternoon, so the snow cover has to start all over again.
Cheers guys and thanks for all the hard work

Lapland cams showing snow returning from the north east with snow falling now in the far north east. Across the boarder into north Sweden they are expecting quite a bit of snow today.

Paul Hudson going for a cold winter....

And once again, a colder than average winter looks the most likely outcome based on the latest projections.

The Lion Inn had been snowed in for 6 days and all roads to Blakey Ridge blocked with snow drifts. This video was filmed on a walk up the valley side from Rosedale, a climb that took 1 1/2 hours due to the waist high drifts and gale force winds

Ignorance is bliss to the snow brigade!
Some people believe the global warming of the last few decades peaked in 2007 and we are at the start of a cooling trend which could last for another 5 - 20 years or so... or even longer if you believe the sun is the main driver. Its too early to tell but this is not Ignorance its based on theory's of solar cycles and/or shifts in sea surface temperature ... Warming or cooling its just a question of what time range you are looking at.

Storm clearing here now. Water started coming under the font door but was able to weep it away. Still rambling away to my north, very intense storm.

massive storm now north of York! lightning everywhere and flash flooding!

If there is a seesaw link, then if Antarctic Ice continues to grow, there will be no recovery in the Arctic.
But is it not saying that the antarctic Ice will stop growing and then arctic will start to recover. I guess this will happen over many many years. Could the change of started already?

No ,not really Ws, have a read around the subject (most of the main ice agencies will supply you with data/links) and you'll see that the two have no relationship apart from being cold. Past 'warmings' has seen the south 'lag' the north in it's ice sheet melt/sea ice retreat.
The move inland of the 'grounding line', of both glacier and ice shelf, is the kind of behaviour you'd expect from a warming Antarctic in the past but we are told that 'ice extent' shows a diametrically opposite trend? I wonder which is right? seasonal ice or age old glaciers thinning/retreating/ice shelf collapse?
But is it not true that antarctic sea ice extent is at a record high (earlier post)... after doing a quick search I have found some saying that the total sea ice extent (north and south) is about average. thinning/retreating/ice shelf collapse all sounds very dramatic but is that not just a part of normal part of nature. What is the total sea ice extent for north and south and how does that compare to a long term average?
Just seen jethro's post... links may answer my question thanks..

Willy wonka faux snow!
-7 in York this morning with localised "Diamond dust" falling through the night, giving a dusting of what looks like snow...All thanks to the nearby chocolate factory adding extra water vapor down wind of the factory.
"To form diamond dust the temperature must be below the freezing point of water, 0 °C (32 °F), or the ice cannot form or would melt. However, diamond dust is not often observed at temperatures near 0 °C (32 °F). At temperatures between 0 °C (32 °F) and about −39 °C (−38 °F) increasing the relative humidity can cause either fog or diamond dust. This is because very small droplets of water can remain liquid well below the freezing point, a state known as supercooled water. In areas with a lot of small particles in the air, from human pollution or natural sources like dust, the water droplets are likely to be able to freeze at a temperature around −10 °C (14 °F)" Ref: http://en.wikipedia....ki/Diamond_dust
