Headline for Southern Uplands
Gales, severe in places. Prolonged heavy rain west.
How windy? (On the summits)

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.

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

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.
