Patchy low cloud across many hills early, lifting and fading, particularly away from west coasts; sun breaking out. A weak front lingers over south Scotland, maintaining low cloud and some light spotty drizzle. Light wind, though a blustery morning in the north Scottish highlands; breezy in south Wales too.
Some early low cloud, mostly clearing; a mild feel with time
West-southwesterly 15-25mph, stronger gusts in exposure; easing and shifting generally westerly, though some variability; 15mph north, less than 10mph south.
Inconvenient gusts and a chilly feeling to start the day, particularly in the north, gradually easing to mostly small effects.
Likely entirely dry
Small risk of a few light spots of rain affecting coastal hills from Mull northward; falling as snow flurries above 800-900m. Later, a small risk of patchy rain from Islay to Loch Lomond.
Variable early, lifting to mostly high terrain and well-broken
From dawn, banks of cloud at variable heights, including lower slopes; high summits likely above cloud layers. Cloud will lift at sunrise, largely above 1000-1000m, though at times lower near the coast; clear periods likely too. Late in the day, a risk of a sheet of cloud approaching Arran/Loch Lomond.
Rising to 70%
Best sunshine well-inland, more of a patchwork near the coast, though high cloud weakening the sun. Very good visibility.
1C from dawn, lifting to 3C Lochaber, up to 4C most other areas. Arran and Munros around Loch Lomond up to 5C. Feeling like -8C where exposed to wind in the early morning.
1000m from dawn, lifting to 1200m, off the summits south of Mull.

Variable 10mph or less.
Negligible.
Precipitation unlikely
Small chance of some light rain around Loch Lomond at and before dawn, though soon clear, and perhaps none at all.
Scattered banks on high terrain in the south
Some fog in sheltered glens at dawn, some banks upslope towards the north but below 700m. After sunrise, fog lifts and mostly dissipates, though banks come and go from Islay eastwards towards Loch Lomond and Bridge of Orchy, mostly 900m and above.
Rising to 70%
Mostly sunny though some high cloud around. Excellent visibility.
3 to 5C, mildest south, most hills rising to at least 5C, perhaps to 7C near Clyde sea lochs.
Likely above the summits, though may just touch high tops towards the north in the morning (including Ben Nevis).

Southerly 10 to 20mph, locally gusty around some western areas, mainly toward Mull.
Mostly small.
Precipitation not expected
Mostly southern hills for a time
Patchy fog in glens at first, lifting into patchy cloud on some slopes, may drift over hills Loch Lomond NP for a few hours before then largely dispersing afternoon.
80%
Sunshine fairly widely, though southern areas may be cloudier for a time. Visibility very good, some haze lower down, particularly toward south.
Around 6C, some cooler spots at first, then some slightly warmer spots by afternoon.
Above the summits, but slight frost inland glens and some sheltered higher areas at dawn.
Fairly widely settled conditions across the country later this week. Some cloud and spotty light rain lingers in north England/south Scotland for a few days, elsewhere becoming mostly sunny; valley fog in many lowland areas early, lifting and dissipating after sunrise for clear hills. Generally milder temperatures and light wind but the occasional stronger gust. The weekend is anticipated to be settled as well, with a mix of cloud and sun, early low cloud lifting and clearing many mountains, only occasional spots of rain in the far northwest of Scotland. A spell of more unsettled weather expected next week, with stronger wind, precipitation, and colder temperatures.
