According to the forecasts available here: http://expert.weatheronline.co.uk/

...it would appear that from Monday next week (22nd Jan) winter will finally arrive in the UK at least. Nationally temperatures will struggle to rise above freezing. Very little wind or precipitation though. Seeing as Europe is now "awash with gas" I can’t see there being any real difficulties but we'll have to keep an eye on the daily flow rates. It’ll be nice to walk to work through frost rather than the rain for a change!

I wonder how the flora and fauna will take it, having been lulled into a false scene of security by the unseasonably warm weather.

I live in Edinbrugh and was given a weather station for my Christmas. Since then the lowest recorded temperature on my unit from Dec 25th to date is 0.6C - this includes night,day etc.
And the unit is well away from the house (in the open) or any concrete that could artificially raise the temperature

Usually there would been frosts 2/3 nights by now - say 15-18 frost. We have had none so far.

About to change today I think!
