That's another plus point for snow. If it settles, then the day is much
brighter than it would otherwise be. Now that low light levels have been
identified as a factor in depression (so-called SAD), that could be of
real benefit to a lot of people.

The present situation is very interesting, with the threat of more heavy rain, strong winds and low pressure and an unusual track for the forthcoming Low. I don't think the SE will get a tremendous deluge, the heaviest rain being just to the west and north of the centre and the Midlands and SW are going to get more than they need again, you could say. This is typical cyclonic November weather and worthy of attention in itself. Fixation on snow is a bit childish.

Well, so did I. At the age of 11 nothing else mattered but its allure had faded well before my 21st. It disrupts my social life in a way that no other type of weather can and as for getting to and from work, well, say no more. Being retired, I haven't got that problem. Snow is meterologically interesting and is quite pretty but for me those positve aspects are decisively trumped by its disruptive nature.

I don't think that "worry" is the right word for many people's reaction
on this group to the possibility of snow.

Certainly there now seems to be strong agreement between the models for
a possibly quite lengthy cold spell setting in next week.



It must be due to strat warming then - in Will's absence I thought
someone needed to mention it ;-)

Cheers

Very likely is.

"Netweather" have just started a "Stratospheric Forecast" - oddly enough
it does not figure in their main menu and the easiest way to find it is
to go to the rainfall radar page and find the "New - Stratospheric
Forecast" link in the menu to the left.

And it currently shows a classic. From today's strong "polar night
vortex" you can watch the temperature actually rise slightly and the
lowest "heights" vanish. The vortex then "splits" with the centres
moving to Arctic Canada and Siberia. Finally the vortex seems to
re-establish, but if you look more closely you will see that it (and the
coldest 30mb air) is displaced to the European side while much warmer
air and 30mb "heights" are in evidence on the "Dateline" side. So there
is not a polar vortex but actually a "dipole" pattern.

It has been like this for several days now, both GFS and ECMW models are
also indicating cold at ther surface so perhaps it is time to get the
thermals out. The jury is still very much out on the snow, especially
in southern and lowland Britain where it doesn't seem quite cold enough
- but some model runs look pretty nasty over northern England and the
Scottish highlands.

And often when the snow stops the sky clears and it is dry and sunny
(and cold) for several days afterwards. That is when you get those
really beautiful images of trees with the snow on the branches
glistening against a brilliant blue sky.

My view on the impending cold spell, is raw, wet and windy, with any snow over high ground. The worst type of weather in my opinion. I've been digging out my thermals etc, two pears of gloves etc, as I have about 40 aerations to do before Christmas ~ Ho ho bloody ho !

What are the two pears for? Are you going to cook and eat them for
warmth? :-)

Yep! A film photographers' nightmare, to overexpose the snow and have
the trees exposed correctly, or expose the snow correctly and have the
trees underexposed.

It's quite easy with a digital camera with bracketing. Film photography
as the same principles except the overlaying of negatives are done in an
actual darkroom with acids and light, much more exciting and hands on.
