Mostly fine elsewhere with little wind.
Snow showers, focused west coast. Later more widely inland. Cloud varying.
Westerly 10 to 20mph.
Mostly small.
Snow showers, focussed on west coast.
Scattered snow or hail showers, focused on western coastal hills, but occasionally extending inland. Towards dusk, risk of clusters of snow showers moving inland to give constant snow for an hour or two.
Varying, breaks inland; extensive in snow.
Cloud varied - often only fragments on higher slopes, with good breaks; these substantial across eastern areas. However, around showers, forming extensively and quickly below 700m.
30% near west coast, 70% elsewhere.
Intermittent sun and very clear air. Visibility abruptly appalling if in snow.

Dry of much of the day, but risk of snow setting in after dusk from the southwest.
Mostly clear, later extensive if snow arrives.
Hills mostly clear, bar a few ragged patches some tops and here and there on lower slopes too. However, becoming extensive later should snow develop.
70%
Periods of sunshine from dawn, but cloud increasing from the west through the day. Visibility excellent, but later very poor should snow develop.
-4C
Most terrain staying at least part-frozen into glens following a hard frost.
Staying cold into early next week. Mountain terrain widely frozen with snow cover. Overnight frosts into valleys, most significant into Highland glens. Fronts will encroach from the southwest by Tuesday, bringing potentially extensive snowfalls. Temperatures then tending to rise midweek, resulting in freeze and thaw cycles - thawing most marked in Wales, perhaps also northern England, but likely short-lived thawing on the Munros. Wind varied, occasionally up to gale force.
