High uncertainty: Direction varying from southwest to northwesterly during day, 30 to 50mph, may ease briefly.
Be prepared for significant wind chill with considerable buffeting and arduous or difficult conditions for periods.
Risk of prolonged rain
Uncertainty over track of small scale low; but scope for a prolonged period of rainfall across the hills, may turn to snow later on highest tops.
Extensive in rain
Hills covered widely in fog in prolonged rain; perhaps for several hours or all day.
30%
Overcast. Visibility likely often poor due to rain.

Rare if any showers
Wet underfoot, or icy on highest terrain with possible fresh snow on tops from overnight. Chance of brief light showers near Cardigan Bay, otherwise dry.
Occasional patches
Some patchy cloud banks may drift over higher slopes in the morning, most frequent toward west Cambrians. Good breaks to tops east and southern areas.

0C. Feeling like -8C if exposed to wind in morning.
800m or just above.
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.
