Planning Outlook
A change from mid week as a low centre crosses Britain bringing stronger wind and initially rain. But precipitation will turn to snow Scottish Highlands on Wednesday then progressively southwards into England and Wales on Thursday - with most terrain frozen and fresh snow lying on most mountains by Friday morning. Cold 'winter' conditions will then persist through next weekend.
