Additional weather information
Met Office Aberdeen meteorologist's view
Winds stronger in the north than indicated in the table with a risk of gales (50mph) throughout the day on higher routes. Strong winds will make for strenuous walking conditions. Tricky navigation in the morning with low cloud and rain. Note temperatures falling and becoming very cold later in the day.
Weather
Cloudy with outbreaks of rain and higher summit snow at first and risk of some heavier outbreaks for a time, but clearing southeastwards in the morning, then brighter, with sunny spells and scattered showers feeding in from the west. Snow on highest peaks at first but freezing level lowering allowing wintry showers down to 400m by end of the day.
Chance of cloud-free hill tops
Nil at first, increasing to 90% by the afternoon.
Low cloud and visibility
Widespread low cloud bases down to 500-700m early morning, perhaps falling to lower slopes in any heavier rain. Breaking up from late morning, leaving scattered cloud, bases of 800-1000m. Visibility poor or very poor at first in cloud and rain, becoming very good outside of cloud and showers by the afternoon.
