Summary for all mountain areas

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.

Headline for Southern Uplands

Gales, severe in places. Prolonged heavy rain west.

How windy? (On the summits)

Southwesterly, 40-55mph, most notably gusty east, 60mph over Cheviots. Tending to strengthen afternoon, reaching 70mph for a time. Easing only well into night from west to 30mph or less.

Effect of the wind on you?

Arduous conditions over the hills. Strong gusty winds will challenge balance and stability all day, including downslope. Significant wind chill.

How Wet?

Rain rarely ceasing, persistently heavy west; flooding

Rain throughout the day from south Galloway to the Moffat hills, at times into western Cheviots; sustained heavy falls, ongoing into evening. Patchier at times further north/east, but still setting in widely for periods. Very wet underfoot, streams in spate, flooding increasingly develops.

Cloud on the hills?

Extensive, lowest southwest

Blanket low cloud cloaks Dumfries & Galloway up to the Moffat hills with bases 300-500m, lowest on slopes facing Solway Firth. Often covering the east Borders and Cheviots above 600m. Some breaks toward the Pentlands.

Chance of cloud free summits?

10%, to 30% Lothians.

Sunshine and air clarity?

No sunshine expected and often dull. Variable visibility, often dull west, best in the eastern Borders during dry periods.

How Cold? (at 750m)

6 to 8C; similar temperatures at all altitudes, may start to drop into night. Feeling like -5C in direct wind.

Freezing Level

Frequent or persistent rain over the Cheviots, reaching the Borders and Lothians for periods, a risk of extended falls here too. Drier Galloway though some patchy rain onto slopes near the Solway. Wet underfoot, flooding.

Cloud on the hills?

Mostly east, variable caps to the west

Cloud shrouds the Cheviot all day, perhaps to middle slopes. Cloud caps over summits will frequent south Galloway and the western Borders as well, though these variable, at times lower but also clearing.

Patchy cloud mostly west

Patchy cloud banks most common on hills toward the Solway, may come and go on slopes above 600m. Some local fog lower down in morning. More often clear hills toward the north and much of Borders.

Chance of cloud free summits?

60%

Sunshine and air clarity?

Sunshine and thin high cloud. Visibility excellent out of cloud.

Above highest summits. Slight frost sheltered valleys in morning.

Planning Outlook

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.
