How windy? (On the Munros)
Westerly 20 to 30mph, increasingly through day to 30 to 40mph, risk 45mph north Cairngorms later.

Chance of cloud free Munros?
40% in west, 70% in east.
Sunshine and air clarity?
Patches of sun, increasingly confined to east and cloud builds in. Visibility mostly very good, but poorer in any precipiatation.

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.
