Christmas Mountain Weather Forecast - Issued 22nd December
Posted 22 December 2011 - 11:19
Becoming mild, cloudy and windy - rain in north
High pressure over France and a mild southwesterly airflow across all parts of the British Isles with frontal systems mainly affecting Scotland. All upland areas will be cloudy with a lot of hill fog around, and quite windy, especially over summits. After an initial frost on Saturday turning mild in all parts. Some localised flooding possible in the Highlands.
The Weekend in Detail:
Christmas Eve Saturday 24th December - A frosty start in many places, but soon turning milder and cloudier as southwesterly winds increase. Showers soon spreading in from the west across the Scottish Highlands and Galloway with more persistant rain moving in by afternoon. This heaviest around Torridon, Skye and Lochaber, and falling initially as snow to around 2,000ft but as freezing levels rise turning back to rain at most levels with lying snow quickly melting. All summits in cloud. Elsewhere too becoming cloudy with some hill fog, especially around western upslopes and a bit of sleet initially over higher summits in the Lake District and possibly north Snowdonia. Mostly dry across South Wales and the SW Moors and eastern parts of the Pennines and Peak District. A wet night in Scotland with rain also affecting parts of northern England so Santa will need a brolly and wellies.
Christmas Day Sunday 25th December - it's just possible a few flakes of snow may fall on the summit of Ben Nevis but that's about it. A fairly wet day across much of the Highlands and Galloway with with the rain again heaviest and more persistant in the west, extensive hill fog and strong winds to all level, gales over summits. Very wet conditions underfoot as remaining snow melts. Just as well everyone will be too busy stuffing themselves on turkey to think of climbing any hills! Drier elsewhere to start with, though very windy, with some rain possible at times for the Lake District and Snowdonia and hill fog affecting most upland areas. South Wales and the SW Moors seeing the brightest weather.
Similar conditions persisting on Boxing Day with Lochaber, Torridon and Skye all looking rather wet but some brighter spells elsewhere, albeit still plenty of hill fog around and strong southwesterly winds. Winds easing on Tuesday though as high pressure starts to build over Britain and cooler air pushes south over Scotland - rain turning back to snow over the hills here as a weakening cold fronts works south. Much cooler midweek with overnight frosts returning and with it mostly dry, much better weather for working off the excesses of Christmas dinner. Some snow cover likely over the Highlands. Becoming milder and more unsettled once again for next weekend with southwesterly winds returning, though Hogmanay not looking quite so wet and windy in the Highlands as Christmas will be.
