Planning Outlook
Colder over the weekend with the mountains near or below freezing point, including frost into glens in Scotland by Saturday night. A small scale low on Saturday most likely affects England and Wales bringing rain, upland snow and a core of strong winds for a time. Sunday then mostly dry, bright and cold. Next week, Atlantic lows passing across or just north of Britain will bring frequent rainfall to western mountains together with upland gales. A mix of chilly westerly air and some milder southwesterlies. Freeze-thaw cycles, with periods of fresh snow mostly for Scottish hills, briefly high tops elsewhere.
