Planning Outlook
Mixed westerly patterns prevail this week, but turning northwesterly toward the weekend allowing much colder air to move in - dropping extensively below freezing point over all British mountains for several days. Fresh upland snowfalls, concentrated toward the west and north of the Highlands, including heavy showers with hail. A period of sustained gales over the tops late this week and likely into the weekend - severe gales over Scottish tops on Thursday at least; significant or at times severe wind chill factor.
