Planning Outlook

All mountain areas of Britain from Friday 28th November 2014

The remnants of the murky weather with low cloud will persist through the weekend, but slowly transitioning to fog in the valleys and some lower slopes, whilst above an inversion, many mountains enjoy superb visibility and very warm. A front will move southeastwards on Monday, followed over 48 hours by cold air (sub-freezing above typically 800m). Then as pressure builds from the south, becoming fine most areas, but frequent snow showers and upland gales on Tuesday and perhaps Wednesday W Scotland. The fine weather may then extend to the north of Scotland. Thus little prospect of significant snowfall.
