Weather hazards

Severe chill effect High likelihood Hide detail

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.

Headline

largely dry, cloudy in the west, sunny in the east. Cold with severe wind-chill.

Weather

Dry but cold with plenty of clear spells through the early hours, particularly across the Cairngorms. Then a cold, largely dry day. Rather cloudy at times towards Creag Meagaidh. Further east, a largely sunny morning across the Cairngorms, but cloud increasing here in the afternoon, perhaps giving a few light snow flurries.

Chance of cloud-free mountain/hill tops at 800m

Generally 80%, with cloud mostly above the summits, but 60% across western most ranges where occasional cloud above 600m is likely.

Visibility

Very good.

Met Office Aberdeen meteorologist's view

Temperatures in the glens likely to be around -10 Celsius at dawn where snow lying, falling to -8 Celsius by midnight.

Sunday 21 January 2018

Sunrise: 08:35   Sunset: 16:18
Moon phase: Waxing crescent

Weather

Dry through the early hours with increasing amounts of high cloud. Snow spreads northeast from late morning accompanied by summit gales. Through the afternoon snow will gradually turn to rain at all levels as mild air spreads in. This will give a risk of icy surfaces in the glens for a time before milder air becomes established early evening. Becoming dry but cloudy in the evening.

Maximum wind speed expected

Light and variable, becoming southerly 20 mph by dawn, increasing to 40 gusting 60 mph by the afternoon, veering west 35 gusting 45 mph in the evening.

Chance of cloud-free mountain/hill tops at 800m

80% early morning, with cloud bases well above the summits. Becoming 10% by the afternoon as cloud lowers, becoming persistent above 700m, often lowering to 500m.

Temperature

  • At 800m -6 Celsius, rising to plus 1 Celsius in the afternoon.
  • Glen -10 Celsius rising to -2 Celsius in the morning, plus 2 Celsius late afternoon.
  • Freezing level 100-200m, rising to 500m early afternoon, above the summits in the evening.

Visibility

Very good at first. Becoming very poor in snow, then extensive low cloud.

Monday 22 January 2018

Breezy with southwesterly gales across high ground. Cloudy with hill fog, particularly in the west. Outbreaks of rain, mainly in the west, light and patchy in the east. Freezing levels above the summits.

Wednesday 24 January 2018
