Last night, I was thinking how this 'could*' go in a similar but the complete opposite way of the beast from the east that never was last year. In that, there are ingredients there that could play into our favour. No easterly is being strongly forecast. But imagine, we see a flip similar to how the Easterly was forecast then flopped back at the 11th hour back in December 2012. Just sayin... (*Last straws have been clutched and dropped, no more straws being grasped. Literally no evidence to back this up)

It was forecast within perhaps 2 days, with the charts up until that point looking very flat and boring, the European high was dominating our weather.
It was the slightest of easterlies, not well forecast, with the air source coming from a very cold near continent. I remember seeing north west tonight, and they gave a quick 2 mins explaining where the cold was coming from (as it hadnt been that cold up until that night). Essentially there was a cold pool of air - no bigger than say wales, at that time over amsterdam, it would rotate around the HP and arrive overnight just when an atlantic front pushed in from the west.
The front stalled, we got blizzard conditions, and as the snow was so dry - really good drifts over the tops of roofs and cars.
The area of of snowfall was quite thin due to the decaying front. The snow line ran from Mid wales, up the border, across North west England and into Cumbria. 20 miles either side saw very little or no snow, or heavy rain further west.

I think this was it.
Editx 2
This was the situation 3 days earlier

really not a million miles away from what we have now, or will have over the next few days, quite startling really.
