Sun best western hills, and also where tops breaks above an inversion around 1000m. Terrain partly frozen, morning frost valleys; but up to plus 5C western tops above inversion.
Headline for West Highlands
Chilly east wind, strongest in south. Patchy cloud and sun, best in the west.
How windy? (On the Munros)
Easterly 20 to 30mph, typically strongest toward south, but possible stronger gusts widely some slopes, not just highest tops.

Precipitation unlikely
Cloud on the hills?
Mostly little; patches on some slopes
Patchy cloud may drift onto some slopes mostly in the range 700 to 1000m, higher tops likely above cloud. Hills generally clearer many western areas.
Chance of cloud free Munros?
80%
Sunshine and air clarity?
Broken cloud and sun, more often sunny toward west coast near Mull. Visibility excellent.
How Cold? (at 900m)
0 to 2C, but up to 5C some western slopes and on higher tops above an inversion. Feeling like -5 to -8C in stronger wind.

70%, but 40% in north and east.
Sunshine and air clarity?
Patchy cloud and sun, best in the south and west. Visibility mostly very good.

Around 0C
Freezing Level

Planning Outlook
Next week, high pressure still dominates, but generally colder air becoming entrained into its circulation from the north, which sees lower temperatures on high terrain, sub-zero over most mountains through New Year. Small amounts of precipitation, occasional showers or snow flurries, winds north or northwesterly.
