Planning Outlook
All terrain will have thawed by the weekend; very wet underfoot with several spells of heavy rainfall, highest totals on south & southwest-facing hills bringing local flooding. A relative improvement on Saturday for many places, but remaining windy, up to gale-force higher northern Scottish tops - rain still frequent around Skye. Deteriorating again into Sunday with further storm-force mountain winds. Chillier westerly winds prevail next week, a return to mostly sub-freezing conditions over Scottish Munros, whilst lower Scottish hills plus mountains in England & Wales will see some freeze and thaw. Showery conditions with hail and upland snow, mixed with occasionally more widespread precipitation.
