Planning Outlook
All mountain areas of Britain from Monday 26th January 2015
Persistent cold will set in again for most of the week across Scotland, with only the odd brief thaw toward higher tops. Snow will fall frequently, concentrated on western and northern mountains, but very little SE Highlands. Further south, freeze thaw cycles, but increasing evidence that late next week, cold conditions with snow to lower slopes will extend south to all mountain areas. Upland gales or severe gales are likely to be frequent, strongest from midweek onward.
