High for the general weather sequence, and for very windy conditions early next week. Lower for rain details from Monday
Generally cloudy with widespread hill fog in the south and west and a little light rain or drizzle. A few clearer spells towards Strathdon.
Gale force winds (gusts over 50mph) make walking difficult and strenuous with a potential to be blown over by gusts. There is often a marked increase in winds through cols or on exposed ridges and summits. Distances can take longer to cover and compass bearings become harder to follow accurately.
Poor visibility presents challenging route finding conditions. Visibility could be significantly less than 50 metres in all directions with few or no visual references, especially on featureless moors or plateaux. Distances become hard to judge and cliff or cornice edges can be difficult to recognise. These conditions require good navigational skills. There is a risk of white-out conditions when mist or fog is combined with extensive snow cover.
Wind significantly lowers the ‘feels-like’ temperature relative to the actual temperature, with even moderate winds significantly adding to the chilling effect. Strong winds can result in a severe and debilitating wind chill many degrees below the actual temperature. This effect will be enhanced in rain or wet snow. Without protection, prolonged exposure could result in frost nip or frostbite on exposed parts of the body and/or hypothermia.
Storm force winds (gusts over 70mph) make walking very strenuous with any mobility virtually impossible over exposed ground. Where these conditions occur there is a high risk of being blown over and even standing may be impossible at times with a risk of being blown off one’s feet. Basic tasks such as using a map, eating, putting on extra clothing or communication become extremely difficult away from any shelter.
Cloudy with some rain in the morning then brighter and mainly dry but turning colder. Windy with summit gales and increasing wind chill.

Cloudy overnight and in the morning with hill fog and some outbreaks of rain and drizzle. This mainly light but turning heavier for a time in the morning. The rain dying out early afternoon though likely to turn to sleet or snow above 1200m before it does so. Cloud then lifting and breaking to allow some sunny intervals and the odd isolated shower, turning to snow on the Munro tops. Perhaps a few more showers in the evening and with colder air, some snow could penetrate as low as 750m, though it will become mainly dry.
10% or less overnight and in the morning with widespread frontal cloud at 450-750m, bases rising a little during the morning, then a more generally increase in chances to 70% in the afternoon and evening, with occasional cloud above 750-900m mainly in showers or on the highest tops.
Often moderate to poor overnight and morning then mainly good away from showers, though briefly poor in snow showers.
Note the falling temperatures and increasing wind chill effect.
Clear spells overnight. Becoming cloudy in the morning, with the odd patch of light rain or drizzle especially towards Creag Meagaidh and Ben Alder, but mainly dry towards Strathdon with some brighter intervals.
A stormy day on the tops, with westerly winds 50 gusts 70mph increasing 70 gusts 90mph in the afternoon and perhaps even stronger after dark.
70% in early hours with broken cloud then falling 30% during the day as widespread cloud at 750-900m spreads in.
Mostly good under cloud but moderate in rain or drizzle.
