Planning Outlook

All mountain areas of Britain from Friday 28th October 2016

The period of westerly winds will be short lived. Models run by the main centres continue to show 'anomalous' conditions well into November. Winds will only rarely be westerly, minimising rainfall on western mountains, indeed most or all mountain areas will continue drier than normal. Temperatures will remain above normal on the hills for a week or so, but then a significant number of forecasts flip to a colder northerly. There may well be a lengthy period next week where fog, haze and general murk shroud lower slopes, but higher areas (above an inversion) may well be in exceptionally clear air).
