Extensive rain, sustained heavy falls over many western mountains, expect flooding. Smaller amounts of rain toward the N/E Cairngorms, also S/E Wales and Peak District. Widespread gales, powerful gusts around high tops, locally downslope to east. Blanket cloud across hills, lowest in west.
Gales, severe high terrain. Prolonged heavy rain, low cloud.
Southwesterly 40-55mph, in places over 60mph around higher mountains, local powerful gusts downslope. Tending to strengthen up to dusk, reaching 70mph for a time. Easing into night to 30mph or less.
Arduous conditions over the mountains. Strong gusty winds will challenge balance and stability all day, including less exposed slopes. Significant wind chill.
Rain rarely ceasing, sustained heavy falls; flooding
Rain across all areas throughout the day with constant heavy falls increasingly setting in. Occasional lower intensity rain mainly morning, smallest amounts typically toward Creag Meagaidh, but still generally wet. Streams in spate, flooding making some paths impassable.
Extensive low cloud
Shrouding the mountains widely, bases mostly between 400-600m, most persistently low toward coast/lochs. Higher bases well inland Ben Alder to Creag Meagaidh, 700-900m, rare breaks, but lowering further at times.
Below 10%
No sun expected, often dull. Visibility widely poor, better locally out of cloud near Rannoch Moor, but still often reduced by rain.
6C, small variation with altitude; then lowering rapidly into night to 1C. Feeling like -5 to -8C in the wind.
Above the summits, but into night a quick drop from west toward 1000m.

Some uncertainty, speed may vary; southwesterly 15 to 30mph, strongest in Lochaber and out to Mull.
Fairly small, though winds may be suddenly uncomfortable in exposure particularly around Ben Nevis group.
Showers onto coastal hills
Scattered showers onto coastal hills from Islay/Jura northward, some drifting inland and around Loch Linnhe, falling as snow above 900m. Showers increase in frequency and intensity with time afternoon in the west.
Mostly higher tops, some breaks
Banks often covering high terrain; lowest bases near the coast, variable between 700-1000m, lowest banks on southern aspects. Patchier further inland across Lochaber, some breaks to tops.
30%
Glimpses of weak sun north but mostly overcast, a veil of high cloud. Very good visibility.
1C. Feeling as cold as -8C in direct wind.
1000 to 1100m.

Southwesterly 25 to 35mph. Strengthening onward into night to gales, risk becoming severe.
Blustery and starting to affect comfortable walking and balance on exposed higher terrain, considerable wind chill.
Showery coasts, snow and hail
Showers most frequent toward coasts and on islands, falling as snow above 800-900m, also hail at times. Some moving inland, but fewer east of Ben Nevis. Near to Arran may also see fewer showers.
Varied, some breaks inland
Often capping coastal tops, base varying in and out of showers, mostly 700 to 900m, brief lower patches. Inland often above 900m, with higher breaks in Lochaber. Some lower fog banks in south in morning.
30%
Glimpses of sun. Visibility often very good out of cloud, but intermittently poor in showers.
0 to 1C. Feeling like -10C directly in the wind.
900 to 1000m. Slight frost inland glens in morning.
Prolonged rain will leave flooding of streams and rivers in many mountain areas early in the new week, with the exception of northeastern Scotland. A frontal system will eventually pass eastwards Monday-Tuesday, wind easing; dropping to freezing above 900m, beware of ice forming on higher Scottish mountains. Drier conditions for many on Tuesday, though showery near west coast of Scotland. By Wednesday, another system sweeps in from the Atlantic bringing further rain and gales. A risk of more heavy rain particularly England and Wales later in the week. A change of weather pattern is likely in the run up to Christmas, as high pressure builds northward, bringing drier weather, possibly chillier with time.
