Planning Outlook

All mountain areas of Britain from Saturday 23rd March 2019

Colder conditions over the weekend with freezing levels ranging between 700 and 1000m. Snow or hail showers focused on W Scotland, becoming increasingly frequent through Sunday when another swathe of gales will affect the Highlands. Drier elsewhere, with just a few showers; these mainly across the Lakes and E Scotland. Into next week, higher pressure will extend across the UK bringing a period of quieter weather with lighter winds and occasional sunshine. Temperatures slowly rising by day, although frosts forming in the valleys/glens at night. Weak fronts may edge into W Scotland at times introducing some low cloud and drizzle here for a time.
