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.

Planning Outlook
A mixed southwesterly weather pattern prevails. Often windy, especially Scotland. Fronts coming in from the Atlantic bringing periods of rain most frequently in west and northwest Scotland - wettest here around Friday night into early Saturday. Small amounts of rain reaching eastern Scotland, more often dry. Patchier and less frequent rain for western England and Wales - higher pressure building for periods to give drier and warmer weather here. Low cloud often shrouding western tops, sometimes to lower elevations near coasts, higher cloud bases eastwards with better breaks.
