Some heavy showers and clear spells in the early hours. These showers becoming frequent by dawn with the best chance of any limited clear, dry spells in the sheltered northeast. A small a chance of hail and lightning and widespread gales, with a chance of storm force gusts on the tops in the morning. Heavy showers continue and spread to all parts in the afternoon. Some brighter spells developing over southern ranges in the early evening as showers become less heavy. Showers persisting over Aberdeenshire and Angus hills through the evening but lighter than during the morning. Winds gradually moderate through the second part of the day. Feeling cold at height.
Chance of cloud-free hill tops
30% much of the day, rising to 60% over northeast range in the morning and then southern ranges in the evening.
Low cloud and visibility
Cloud frequently falling down to 800-1000m with visibilities falling poor in hill fog and heavy rain as heavy showers pass through, best chance of clearer spells in the morning over the sheltered northeast, and then for southern ranges through the evening.
