Whilst this is great enthusiasm, I would urge you all to be patient for a number of reasons. It is true that it's been very cold up in the mountains of late: http://www.metoffice.gov.uk/weather/uk/wl/sennybridge_latest_weather.html
But for the icefalls to come into climbable nick they need a good week of sub zero temperatures. Whilst they would be climbable before this, being the most southern winter routes in the UK, they attract a lot of attention. Hoardes of enthusiastic winter warriors kicking their way up partly formed ice falls will at best, delay the forming and spoil the experience for everyone else, and at worst (particularly in areas such as Craig-y-Llyn, one of the first venues to come in) damage and destroy rare plant life and fauna and jeopardize future access.
Similar can be said of the North Face of Pen - Y - Fan. Whilst it's a choss fest no one in their right mind would go near in the summer, it also happens to a natural environment to a lot of varied biology. If it's too cold, consistently, snow won't consolidate and you run the risk of damaging the rock and turf underneath, not to mention your own legs when you inevitably stab your thigh with a crampon when you fall in to your waist. Conversely, too much snow too quickly will mean that the turf isn't frozen and the route and plants that live on it could be damaged irreparably.
I would therefore urge you all to be patient and protective of our valuable environment and the climbs in it which we are privileged to have access to. If you haven't already, please read this: http://www.thebmc.co.uk/north-wales-white-guide
Whilst it's specific to North Wales, much of the content is applicable down south too, and any conscientious winter climber should care about what it says. So please, wait it out. Give it chance to form, and don't just grab your axes and wage war on the routes the second they have a speckle of dust on them.
Those looking for good conditions, you'd be well advised to check it out early Friday morning for your best bet. I'll be going up Thursday night for a recce I think. Most likely venues given current conditions would be RAC Corner, Craig - Y - Llyn and possible Torpantau. There is unlikely to be enough snow to make the North Face routes climable.
