High confidence for the general trend, but lower for detail of rainfall through Tuesday.
A very windy end to the day with gales across most areas, and severe gales above munro level. Largely clear skies but one or two showers possible in the far west.
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.
Harmful UV levels from sunlight increase with altitude giving a greater risk of sunburn and eye damage, even on some overcast days. On breezy days, the cooling effect of wind on exposed skin may disguise any feeling of sunburn until it is too late. If there is snow cover, glare increases the effect of UV rays especially on the eyes. It is advisable to wear sun block, protective clothing such as a long-sleeved top and hat and have good quality eye protection.
Sunshine and a few showers in the morning, cloudier with some rain across the south and west by late afternoon. Widespread upland gales, perhaps severe on summits through the morning.

Isolated showers may continue across the far west through the early hours, turning sleety above around 1000m, the majority confined to Creag Meagaidh and the Monadhliath Mountains. Any remaining showers will soon die away through the morning, leaving most areas dry by mid morning with some sunshine. Cloud will thicken from the southwest through the afternoon, bringing outbreaks of rain across most parts, but heavier and more persistent towards Ben Alder, and with best shelter towards the northern Cairngorms.
80% through the bulk of the day, with most slopes largely fog free. However, some capping cloud is likely above 900m, mainly across the Caingorms. Decreasing to 20% after sunset as cloud lowers quite widely to 700m within rain.
Very good with some far reaching views on offer. Deteriorating to moderate through the evening in the south and west, and locally poor in rain with some neighbouring slopes becoming obscured.
Gusts may be closer to 65mph above 1000m through the early hours.
Thick cloud will remain in place across the area, bringing periods of rain and drizzle through the morning. Clearer conditions will arrive from the west by late morning, bringing a return to scattered showers and some sunshine. Into the evening, showers will become more widespread and heavy with a risk of thunderstorms, mainly for the north of the area, and may turn increasingly sleety on summits.
Mainly light through the morning, with a westerly breeze of 15-20mph with gusts to 30mph developing through the later afternoon.
20% with hill fog quite widespread above 600m, this slowly clearing from the west by mid morning. Generally 60% through the rest of the day with some fog associated with showers.
Moderate or poor at first, but improving to very good by around midday and falling temporarily during showers, perhaps to poor in any heavy showers.
