Nevertheless, away from western Scotland, total rainfall will be small until Friday, when as a front coming in from the northwest, slows down, many areas will have a lengthy period of rain. Upland gales will develop on Thursday across the Scottish Highlands, and upland severe upland gales will be widespread on Friday - although easing markedly across the W & N Scottish Highlands. Remaining mild. Underfoot, away from the W & NW Highlands, still very dry.
