Thu 31 Jul 2014

Cloudy overnight in the west with outbreaks of light rain, clearer and drier in the south and east. A band of rain will then push in to Skye and Lochaber around dawn, this occasionally heavy. This will slowly shift northeast to affect Glen Affric and Torridon by late morning and may remain fairly slow-moving during the afternoon. Conditions further south should start drier with perhaps some bright spells, however scattered showers are likely to develop during the afternoon, these occasionally heavy and thundery with a risk of hail. The very far north is expected to remain mainly dry. Drier conditions then expected to develop during the evening.
