Planning Outlook

All mountain areas of Britain from Friday 19th January 2018

Cold westerly winds will bring further clusters of snow or hail showers into western regions for the rest of the week. Fewer showers by Saturday as winds ease and pressure builds. However, a front which moves in from the south-west later Saturday into Sunday brings a risk of persistent snow in some areas, which may transition widely to rain as temperatures lift. A chance that across much of the Scottish Highlands, it remains as snow much of Sunday. Into next week, expect periods of rain or snow and possible gales, with cycles of freeze and thaw, although the Scottish Munros rarely above freezing point.
