High for mainly dry and settled conditions on Wednesday and Thursday. Medium for details on Tuesday and Friday and Low on Saturday.
A fine end to the day with clear skies and light winds, although some patchy cloud by midnight.
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.
Heavy and persistent rain can lead to drenched clothing and footwear with waterproofs often becoming soaked through, especially if accompanied by strong winds. This can lead to significant loss of body heat and an increased likelihood of hypothermia. Terrain may turn increasingly boggy underfoot while streams can flood and become impassable. There may also be a risk of flooding in valleys or glens. If there is snow cover, a heightened avalanche hazard is possible and avalanche reports should be consulted where available.
Mostly cloudy with occasional rain and drizzle. Gales over the tops and feeling cold.

Dry with some clear spells during the early hours, but becoming increasingly cloudy overnight. The cloud will continue to thicken and lower during the morning with outbreaks of rain and drizzle, this most persistent around Schiehallion and Ben Lawers. Drier and brighter spells expected over the Aberdeenshire and Angus Hills. The cloud lifting and breaking during the evening with a scattering of showers pushing into the west.
60 to 80% early hours, but soon Nil to 10% around Schiehallion and Ben Lawers, extensive cloud with bases 600m or less, but 30% in more eastern areas with cloud bases more typically 600 to 900m around the middle of the day. Becoming 70% during the evening as the cloud begins to lift and break.
Mostly good or very good, but moderate or poor in rain and drizzle. Very poor at times over the tops.
Feeling cold over the tops with a significant wind chill.
Rather cloudy in the west during the early hours with showers, these turning wintry over the tops. Mainly dry with well broken cloud in the east. This leads to a mainly dry and bright day with some sunny spells, perhaps the odd shower around Schiehallion and Ben Lawers, wintry over the tops. Dry with well broken cloud in the evening, clear skies at times and temperatures quickly falling.
West 15 to 25mph gusts 35mph, but gusts 50mph during the early hours. Winds easing later in the day.
Typically 80% or more, patchy cloud with base 900m or higher, but 30 to 50% during the early hours, more extensive cloud with bases around 600m.
Mostly very good or excellent, but moderate or poor in any showers.
