Its turning colder as the wind moves round more westerly, the freezing level has been lowering this afternoon and will settle at around 600 metres. Moderate amounts of snow is expected on higher ground with strong winds which will lead to significant snow transportation and deeper accumulations of wind slab developing. There are many areas where the snow will fall on to bare terrain. In some localised areas these accumulations will be deeper and lay on older snow and will be moderately well bonded, especially on high wind sheltered North to Easterly aspects. I was in Torridon today and there were just traces of snow visible on the highest summits but there will be more snow further inland away from the sea. According to the weather forecast the hills should look a lot whiter tomorrow!
