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.

Planning Outlook
Unsettled this weekend: often cloudy and patchy rain for most. Variable winds cause rapid local changes in cloud amounts, rain, and impact on walking. The freezing level may lift somewhat, isolating snowfalls to higher Scottish terrain. In the coming week, periods of precipitation and wind will affect most mountains at least every few days. Scottish Munros generally below freezing point, with snow cover and drifts most substantial from the Cairngorms to central and southern Highlands, some additional falls in the week ahead (with continued flooding risk too); much less precipitation northwestward. Hills in England and Wales may see a period of freezing levels above the summits as a southerly flow brings slightly milder air to the country. An indication of colder easterlies in February, though detail is very uncertain.
