All mountain areas of Britain from Sunday 21st December 2014
The outlook for the Christmas period is complicated (to say the least). Over the last few days model forecasts have shown a significant bias toward cold conditions (very low freezing level) after Christmas. The timing and longevity of this is very uncertain: A significant minority of model forecasts suggest several very cold days toward New Year, whilst others bring milder conditions back in, at least intermittently. Until then frequent upland gales, rain, or in Scotland intermittently snow falling to lower slopes.
