A frontal system will track eastwards this evening bringing snow, followed by a brief period of rain at the highest elevations overnight. A colder day is expected during daylight hours, before the freezing level rises well above the summits once again.
There is one constant in this variable picture,. The wind, which will be consistently gale force.
A period of instability is expected overnight, as rain turns to snow. This will most likely be short lived, with gradual consolidation of the snowpack as the freezing level drops afterwards. Moderately bonded windslab will continue to develop on North-West through North-East to East aspects above 900 metres. The full forecast for the Northern Cairngorms is permalinked here at: https://www.sais.gov.uk/northern-cairngorms/
A view into Coire an t-Sneachda with some scoured areas on crag aprons. Although the same aprons may be covered with windslab tomorrow. Note also the firm icy snow surface which has been exposed to the wind in recent days.
Fresh soft slab around corrie rims, here in Coire Cas.
Fresh windslab on a North-East aspect at around 1000 metres. Note the cracking between the ski tracks while doing a kick turn.
