Strong winds early in the day, gale force particularly toward the Cairngorms, lessening to lower speeds with time for all areas. Some early rain and upland snow in northeast Scotland clears. A few showers near west coasts fade. Cloud breaks above many tops with some sunshine, but remaining chilly all day.
Fairly light wind most of day, largely dry, sun and high cloud.
Westerly 20-25mph in morning, briefly stronger at dawn, easing to 15mph or less, shifting southwest then southerly afternoon. Into evening, mainly beyond dusk, rising southeasterly 30-40mph, then variable lulls into night.
Mostly small during daytime.
Largely dry until late
Some early showers in west soon fade for a lengthy dry window. Into evening, rain develops from south, setting in persistently and increasingly heavy into night.
Just summits with breaks, deteriorating late
Patchy cloud on tops soon lifting, breaking up to banks grazing terrain above 800m, and likely above the summits into afternoon. As evening approaches, cloud lowers onto high terrain, filling in after dark.
80%
Patchy sun, some longer bright windows midday, then high cloud building. Very good visibility, a little haze to the south.
5C rising to 7C, staying elevated and rising slightly further overnight. Feeling near 0C in the breeze at first.

Varied from before dawn, soon northwesterly, swiftly strengthening to 55-70mph; only later lessening.
Any mobility difficult in exposure, crawling may be necessary in strongest wind; severe wind chill.
Rain later breaks to showers
Rain fairly persistent from dawn, a few patchier moments but then setting in for several hours at least, steadiest heavy falls towards northwest hills. Later, will break into scattered showers drifting from the northwest.
Extensive
Blanket fog to low slopes well into the day. Later, cloud begins to lift and break up somewhat, but mostly capping terrain above 700-800m lower bases west around showers.
10%, only later rising to 40%
Overcast and dull well into the day with poor visibility. Some sunny bursts late in the day.
Around 3C most of the day, though may just start at a milder 6C. Feeling as cold as -15C in strongest wind.
Above the summits, but may lower to just graze highest tops later in the day.

South-southwesterly, 30mph or briefly less at first, rising rapidly to reach 50-60mph+ as day goes on, little change afternoon.
Deteriorating, becoming arduous walking, increasingly difficult mobility on higher terrain, significant wind chill.
Heavy rain sets in
Dry around dawn, for a few hours east Wales, but patchy rain soon moves in from west, setting in increasingly heavy middle of day onward, continuing into evening. Showery into night.
Lowering to become extensive
Initially most cloud above the hills, apart from odd patches at varied heights. Increasingly cloud will lower onto hills, forming to lower elevations many south and western slopes; some higher breaks remain eastern mid-Wales.
70% at first, dropping to 20%
A little weak sun through high cloud from dawn, soon giving way to overcast skies. Good visibility at first becomes hazier, then poor as rain sets in.
4C from dawn, rising to 10C by later afternoon, then falling into night. Always feeling below freezing in the wind.
Above the summits.
A deep area of low pressure moves toward northwest Scotland into the weekend to bring widespread rain and gales, stormy conditions develop over many mountains, the strongest sustained winds over Scottish tops into Sunday in excess of 70-80mph with more powerful gusts. Temperature will vary, briefly above freezing to all tops, then back just below zero on Scottish Munros by Sunday with frequent showers of hail and snow on high mountains. Atlantic west-southwesterlies remain dominant next week, bringing several low pressure systems with rain and wind, punctuated by brief clearer windows.
