Chance of cloud free Munros?

30% Lochaber/coasts, to 60% south.

Sunshine and air clarity?

Bursts of sunshine, sunniest Loch Lomond. Visibility excellent away from showers, but very poor where snow falls or blows around and also if in cloud.

How Cold? (at 900m)

-5C (to -8C at 1200-1300m). Wind chill feeling like -15 to -20C on tops.

Freezing Level

Most terrain frozen, sub-zero all day glens upward. Just above freezing up to 300-400m nearest the coast and on islands.

Planning Outlook

Significantly cold wintry conditions into the start of January. Air temperature well below freezing on high terrain, plus low minima into many glens and valleys with sustained hard frost. Strong northerly winds later this week giving severe wind chill. 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. Staying cold into next week with scope for snowfalls more widely.
