Planning Outlook

All mountain areas of Britain from Wednesday 22nd April 2015

Extensively dry weather continues during Wednesday and Thursday, with good amounts of sunshine and light winds. However, the north-western Scottish Highlands will see frequent cloudy skies, often shrouding the mountains. Elsewhere most tops will be widely clear. Friday onward: a change to more unsettled conditions is expected, as fronts move in from the south-west. Gradually, a cyclonic north-westerly pattern may develop, bringing much cooler air and possible snow showers to the Scottish Mountains.
