Planning Outlook
A cold frosty start to Monday, but milder southerly air arrives - dry and many hills clear with hazy sun, but gusty wind, risk of local gales west coastal mountains of Scotland. Quite warm by Tuesday, but strong to gale force southerly winds more widely; dry for many, rain encroaching into western Scotland, thawing of recent snow. Staying warm on Wednesday for many, but likely becoming cooler later in the week. Scotland likely remains changeable, often windy later in the week, rain at times, varying temperatures, at times below freezing on higher Munros. England and Wales sees occasional rain or showers late week, but some drier days and lighter winds.
