Scotland: Scattering of snow showers in the west, mainly coastal hills, but for most areas dry, cold and mostly sunny. Towards dusk, risk of zone of more persistent snow moving inland from west coast. England and Wales: Areas of snow across Wales will gradually ease away in afternoon. Mostly fine elsewhere with little wind.
Varied conditions. Clusters of snow showers. Hill fog extensive in snow.
Direction will vary, mostly easterly in morning then northwesterly in afternoon, occasional lulls, but 15 to 25mph for several hours, risk 35mph high tops.
Sometimes small, but beware of deteriorating conditions and significant wind chill at times.
Risk periods of snow and hail
Clusters of snow showers drifting across areas. In some areas may merge into a zone of constant snow for a few hours, whilst other areas see very little. Risk isolated thunder. Snow showers tending to ease through the afternoon.
Extensive around precipitation
Cloud varied - sometimes only fragments on higher slopes, with good breaks. Around precipitation, forming extensively and quickly below 700m.
40%
Intermittent sun and very clear air. Visibility abruptly appalling if in snow.
-4C
Terrain widely frozen. May rise above zero up to 300-400m for a time.

Northwesterly 10-15mph, backing through day to southwesterly, later 15-25mph.
Mostly small, but marked wind chill later in the day.
Rain, preceded by snow, in afternoon.
After a dry morning, rain and snow will move in from the west in the afternoon. Snow initially falling to 400-500m, but will increasingly revert to rain at all levels.
Increasingly extensive
Banks of cloud covering higher slopes in morning, but some breaks; especially in the east. Then becoming extensive in afternoon down to lower slopes.
40% lowering to 10% in afternoon.
Patchy sun at first, but soon overcast. Visibility very good at first, but becoming poor or very poor in precipitation.
-1C, rising to 3C by end of the afternoon.
Much of the terrain frozen into the valleys from dawn following a widespread frost. However, milder air arriving in afternoon.
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.
