A generally dry day with occasional light snow showers later. Visibility was good for the most part unless you were enveloped in one of the showers that tracked through.
Following the snowfall of the last 24 hours there is a thin veneer of cold, light snow overlyingÂ the old firm snowpack. In most places this makes travel quite pleasant, but it remains firm and consequential in the event of a fall or slip in steep locations.
The cold arctic maritime airmass will continue to be a feature of the coming days. As such little change is expected. The freezing level will fluctuate, rising to 800 metres in the Northern Cairngorms. However, in practice the snow will remain cold from around glen level upwards, so visibly the picture will remain arctic.
For example today the temperature was -9 degrees on Cairngorm in the morning, while the snow surface was -7.6 degrees in Coire Cas at 1000 metres. The air temperature at the same location was -6.8 degrees.
Although cold, there is a bright and sunny day in prospect tomorrow.
