Additional weather information
Meteorologist's view
Very challenging conditions in the morning with rain, severe wind chill, low cloud, and walking will be extremely difficult on exposed ground with a high risk of being blown over in 60-70mph winds. Conditions much improved later in the day.
Weather
Rain spreads east in the early morning, heaviest and most persistent over ranges west of the A9, generally patchier over more sheltered northeastern areas such as Ben Rinnes and Ladder Hills. This accompanied by widespread summit gales and some storm-force gusts over the highest summits. The worst of the rain clear by mid-morning, but staying rather cloudy in the west until the evening, best of the clearer, brighter spells in the northeast. Further mainly light showers spread east through the rest of the afternoon, meanwhile winds will gradually ease. Becoming dry with clear spells in the evening.
Chance of cloud-free hill tops
30% or less in west until evening, 70% in northeast. Rising to 80% or higher for all in evening.
Low cloud and visibility
Quite widespread cloud down to 700-900m in the west much of the day, falling to 500m for a time in the morning with poor visibilities in rain. Generally clearer summits in the sheltered northeast. Cloud lifting and breaking for all through the late afternoon and evening to allow some good clear spells and visibilities.
Ground conditions
No recent ground conditions report available.
Mountain weather information
Weather
A much better day compared to Saturday. Mostly dry throughout the day with lengthy bright or sunny spells in the morning, a bit more by way of cloud in the afternoon. Mostly light winds by day. Cloudier in the west later in the evening with some outbreaks of rain and freshening southerly winds.
Chance of cloud-free hill tops
90% or higher until late evening.
Maximum wind speed expected
Generally west backing southwest 10-15mph. Increasing south to southwest 25-35mph late evening.
Temperature
- At 800m Plus 4C rising to plus 8C by day.
- Glen Plus 6C rising to plus 17C by day.
- Freezing level 1400m before dawn, then rising well above summits.
Low cloud and visibility
Summits largely clear through the day with excellent visibilities. Any afternoon cloud largely above the summits but the odd patch possible around the very highest summits. The odd patch of valley fog or cloud below 300m in the early hours, soon burning away after dawn. Cloud becomes more widespread from the west shortly before midnight, down to 500-700m.
Ground conditions
No recent ground conditions report available.
