The Met Office has said the mild temperatures could drop up to 10C as we say goodbye to British Summer Time. The clocks will go back at 2am on Sunday (October 28). High pressure in the west of the UK will bring cold, arctic air southwards across the country on Saturday. Met Office Chief Meteorologist, Laura Paterson, said: It will feel very cold this weekend, with strong winds bringing heavy showers to many parts. Northern facing coastal areas will see the most frequent showers, whilst elsewhere will see more in the way of sunshine. These showers could contain hail, and turn to snow on the high ground, mainly Scotland, Northern Ireland and perhaps northern England. It will be a marked change from the balmy, t-shirt weather North Devon has been experiencing the past couple of weeks. As we go into next week, it looks like it will be less cold for much of the country but looking more unsettled by the middle of the week.
