Summary for all mountain areas
Chilly northeasterly winds with extensive cloud with patchy precipitation locally. Best breaks and sun western hills of England and Wales, and western Scotland. As a cold front edges south, cloud may break up more widely later for the Highlands with colder conditions developing on the hills.
Headline for Southern Uplands
Chilly northeast wind. Cloud and hill fog mainly in the east. Clearer in the west.
How windy? (On the summits)
Northeasterly 10 to 15mph, but tending to lift to 15 to 25mph through the day. May lift to 30mph over tops.
Effect of the wind on you?
Mostly small, but increasingly considerable wind chill where exposed to the wind and rather gusty.
How Wet?
Risk locally light precipitation in east.
Mostly dry, but scope for a little patchy spots of light rain or snow grains from the banks of low cloud in the east.
Cloud on the hills?
Cloud banks mostly in the east.
Cloud banks mainly confined to eastern hills east of the M74 with bases around 500-700m. Patchy banks further west where hills may be mostly clear.
Chance of cloud free summits?
30% in east, 80% in west.
Sunshine and air clarity?
Cloudiest in the east, best sun in the west. Visibility mostly very good outside of any precipitation.
How Cold? (at 750m)
Around 0C, small change in temperature with height.
Freezing Level

How windy? (On the summits)
North-westerly backing westerly 15 to 25mph, increasing to 25 to 35mph through the day.
Effect of the wind on you?
Be prepared for increasingly blustery conditions with considerable wind chill and buffeting.
How Wet?
Mostly dry
Dry much of day, risk patchy precipitation later, snow flurries on upper slopes.
Cloud on the hills?
Lowering onto hills from west.
Hills starting clear, but increasingly low cloud will move in from the west to cover upper slopes or tops near and west of M74. Eastern hills may stay clear.
Chance of cloud free summits?
80% at first, lowering to 30% in west, 60% in east.
Sunshine and air clarity?
Bright start with sun through high cloud, but cloud building from west. Visibility mostly very good or excellent. Turning misty later in the west.
How Cold? (at 750m)
Around -1C, perhaps plus 1C later. Feeling closer to -8C in the strongest winds.
Freezing Level
All levels at first, following widespread frost into valleys, but lifting to 500-600m, perhaps 800m later.
Planning Outlook
Up until end of the year, high pressure still dominates. Significant change from New Year's Day as a cold front introduces, a much colder and strong northerly giving severe wind chill with temperatures well below average for the first week to the New Year with frequent and heavy snow showers moving into northern areas and running down coastal extremities with significant accumulations. Elsewhere, lots of dry and sunny weather, although occasional organised bands of snow will feed south at times in the Arctic airflow. All terrain becoming frozen, with scope for very low valley temperatures over snow cover when northerly flow eases.
