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. Dry, but snow soon after dusk.
Southeasterly, strengthening through day from 20-30mph after dawn to 30-45mph before dusk. Strongest wind Galloway.
Walking increasingly difficult, in places on lower slopes, and feeling bitterly cold as wind chill becomes significant from west.
Dry much of day, but snow after dusk.
Very likely dry through daylight, but then fronts edging in from southwest after dusk will bring increasing threat of persistent snow. Time of onset uncertain, most likely not until early evening - perhaps midnight Borders.
Hills cloud free; but may lower onto the hills later in the day.
Most hills cloud free, possibly for much the day. But patchy cloud higher slopes east from Moffat will tend to lower toward 450m from late afternoon and increasingly cap higher tops westward toward Galloway.
90% lowering to 20% late in the day.
Sunshine giving way from south as cloud thickens. Visibility very good although increasingly hazy and appalling in overnight snow.
-2C. Will feel as cold as minus 16C directly in the wind.
Almost all terrain frozen.

Very turbulent conditions developing. Southeasterly winds; lifting through day to 45 to 65mph.
Be prepared for increasingly difficult conditions, as turbulent and very powerful winds accelerate over the hills.
Rain, or for a time snow or refrozen rain.
Frequent spells of rain, for a time early in the day falling as snow to mid or upper slopes, or even refrozen rain. Will revert to rain at all levels as day progresses.
Extensive
Cloud widely shrouding the hills from lower slopes upwards.
20%
Overcast. Poor or very poor visibilities.
-1C, tending to lift to plus 2C. Feeling closer to -15C in exposure to the wind.

South to southeasterly 20 to 30mph; strongest in the morning, but easing out to 15mph in the afternoon.
Some buffeting and considerable wind chill in the morning, but becoming small afternoon.
Rain and drizzle on and off
As an area of low pressure tracks across through the day, areas of rain and drizzle will circulate around giving precipitation on and off, some perhaps heavy.
Extensive
Be prepared for extensive hill fog through the day from mid slopes upwards. Some patches to lower slopes at times too.
20%
Mostly overcast. Rather murky through the day.
Around 3C, but feeling more like sub -5C in direct exposure to the strongest winds, before they ease.
Above the summits, with terrain thawing out.
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.
