Southern Uplands
The Galloway hills eastward to the Lammermuir hills. The Cheviots (including higher hills within the adjacent Northumberland NP).
Monday's Forecast
Windy, walking impeded
Blustery conditions enough to give buffeting on higher terrain or affect balance on exposed ridges. 25 to 40mph.
Patchy rain or drizzle
Rain on and off, or generally drizzly - total amounts small, but may be persistently damp, especially where hills are shrouded in cloud.
Poor visibility
Murky conditions with areas of fog shrouding the hills, making navigation challenging. Map and compass essential.
Warm
Comfortable temperatures on the hills, 10 to 15C on tops, feeling pleasantly warm especially on lower ground. Beware of feeling cooler if exposed to wind on higher terrain.

Planning Outlook
Staying unsettled during the next week to 10 days as westerlies prevail - areas of low pressure passing north of Scotland with frontal systems bringing frequent rain, wettest over western mountains in Scotland. Often windy, sustained periods of gale-force westerly winds over higher terrain. Fairly cool by Tuesday onward, close to freezing on highest Scottish summits on Wednesday morning, possibly again for a time next weekend; often considerable wind chill on the mountains. Higher pressure and better weather tends to expand further north later in month.
