Additional weather information
Met Office Aberdeen meteorologist's view
Note sub-zero temperatures at height
Weather
Wintry showers along coastal districts at first. Cloud will bubble up through the morning bringing rather more widespread wintry showers by late morning. The afternoon will see a lot of cloud with scattered slow-moving hail and snow showers, occasionally heavy with the chance of an isolated thunderstorm across southern Lochaber and Argyll. More in the way of drier weather across Arran, Kintyre and Jura. Showers will slowly die away in the evening.
Chance of cloud-free hill tops
60%, best chance first thing
Low cloud and visibility
Very good visibility with great air clarity outside of cloud and showers. Otherwise areas of cloud down to 800 to 1000 metres shrouding the summits, this likely to be quite persistent across the north of the area.
