Planning Outlook

All mountain areas of Britain from Saturday 24th March 2018

A cool westerly pattern this weekend, with temperatures sub-zero above 700-800m, and overnight frost in valleys. Scattered showers, focused on western Scotland, but plenty of dry and bright weather. Cloud breaking to many high tops and visibility excellent. A chilly breeze, although winds relatively light for many areas. Changeable next week, with frontal systems approaching from the Atlantic, but then a switch to colder northerly winds from midweek and toward Easter. The freezing level dropping widely, and very cold conditions are possible on many mountains. Further accumulating snowfalls are likely, although detail is uncertain.
