The UK could be hit with patchy frost over the next few days as Arctic air sweeps in, bringing with it blustery showers and a small risk of thunder and hail, the Met Office has said.

There could be some snow or sleet on Scottish mountains, with temperatures about 4C or 5C below average for the time of year, coming in at about 10-13C in Scotland and 13-16C in southern England.
