After a hard frost, mostly dry and bright, but feeling increasingly bitterly cold as southeasterly winds strengthen and cloud thicken through the day ahead of a front, which will bring and increasing risk of upland snowfall, in across western mountains toward evening, and then spreading to all parts overnight.
Bitter chill in strengthening southeast winds. Snow arriving overnight.
Southeasterly, strengthening through day from 20-30mph after dawn to 30 to perhaps 45mph before dusk.
Walking increasingly difficult, in places on lower slopes, and feeling bitterly cold as wind chill becomes significant.
Precipitation unlikely
Very likely dry all day, although in the afternoon increasing threat of patchy snow near Skye - more likely after dark. More widely snow extends northeast overnight.
Very little
Here and there, cloud above 900m, but most summits are of cloud, aside from some fog patches in the glens in the morning.
80%
Sunshine may well be extensive, away from fog banks in some glens. Visibility excellent.
-3C, although a little less cold near coast. Will feel as cold as minus 16C directly in the wind.
Almost all terrain frozen: partial thawing some lower slopes, mainly near the coast.

Very turbulent conditions developing. Southeasterly winds; lifting through day to 50 to 70mph.
Be prepared for increasingly very difficult conditions, as turbulent and very powerful winds accelerate over the mountains.
Occasional snow or refrozen rain
Occasional snow. Level to which snow falls varying, to lower slopes in some areas, but upper slopes elsewhere, with some hills seeing refrozen rain.
Fairly extensive, breaks in northwest.
Be prepared for fairly extensive hill fog in the south and east down to mid slopes. Mainly upper slopes or tops with some breaks, up to Ben Hope and west coast.
30%
Overcast. Visibility often poor or very poor, good at times in the north and northwest.
Around -3C, will tend to rise to between -2C and plus 1C. Feeling more like -18C in direct exposure to the wind.
400-600m, highest near west coast. Lifting to 600-1000m; varied across area.

East to southeasterly 15 to 25mph, tending to ease through the day.
Be prepared for considerable wind chill in the strongest breezes, although tending to ease through the day.
Becoming mostly dry
A few patches of rain, or above 1000m, snow in the morning; mainly in the east. By afternoon, very likely dry.
Occasional bank but mostly clear W co.ast.
Occasional banks covering some mid to upper slopes in the east, but these tending to break off the hills as day progresses. Very little toward west coast.
60%
Cloud layers thinning and breaking to reveal some sun, mostly widely west coast. Visibility generally very good.
Around 1C, but feeling closer to -10C initially in the strongest winds before they ease.
Gradual thaw to upper slopes, with freezing level around 1100m.
Unsettled conditions will prevail over the next week to 10 days, with periods of upland gales or severe gales with precipitation frequent, mostly rain, although intermittently snow Scottish Highlands, more rarely elsewhere. Driest conditions (relative to the average) will likely be in the northwest Highlands, given the often backed flow, as the low pressure areas track in.
