Mountain weather
North Grampian Mountain weather forecast table
Confidence
High confidence for scattered showers on Friday and for general showers/ rain on Saturday but lower confidence in the detail and timing of rain Saturday.
This evening forecast
A dry start with bright spells. Turning cloudier through the evening with outbreaks of rain moving northwards over the area. Strong to gale force southeasterly winds.
Mountain weather hazards
Hazards apply at or above 300m, reflecting the more severe conditions which can occur at altitude.
Strong Sunlight
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.
Poor Visibility
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.
Thunderstorms
Lightning is a significant mountain hazard which can result in serious injury or death. Mountain terrain often leaves one highly exposed to lightning strikes. Hail may give unpleasant conditions with torrential rain and localised flash flooding also possible, mainly in Summer months.
Mountain weather forecast
Largely dry morning with heavy, perhaps thundery, showers developing later.

Additional weather information
Met Office Aberdeen meteorologist's view
Sunny spells on Friday resulting in high UV levels, so appropriate sun protection should be used. During the afternoon some showers will develop, these will be heavy and so waterproofs might be needed. Within the showers there is a low risk of thunderstorms developing so walkers may want to keep this in mind
Weather
Cloud and outbreaks of rain clearing through the early hours to leave largely dry conditions, with the odd isolated shower possible, and sunny spells. Showers becoming more frequent and heavy from late morning with a risk of thunderstorms through the afternoon. Turning drier in the evening with sunny and clear spells.
Chance of cloud-free hill tops
20% in the morning, rising to 60% in the afternoon and 80% by evening.
Low cloud and visibility
Cloud bases 500-700m in the morning. Some low cloud bases lingering in the afternoon especially in showers before mostly clearing in the evening. Visibility poor in cloud and very poor in heavy showers.
