All mountain areas of Britain from Thursday 5th March 2015
A change in weather pattern will bring extensive thaw to all mountain areas - although the higher Scottish Highlands will intermittently be below freezing point again early next week. Until this weekend, often strong winds, extensive low cloud focussed on western mountains, and also areas of rain and drizzle. A front may well drift slowly and erratically south across the W & NW Highlands this weekend, bringing considerable rainfall. Although there are differences between different model forecasts, next week is likely to be substantially dry, although it may be later in the week before these conditions extend to N Scotland.
