All mountain areas of Britain from Wednesday 8th July 2015
A band of showery rain will move southwards across all ranges on Wednesday followed by a cold northerly airflow. By Thursday showers will be confined to the north and east of Scotland by which time they will have turned to snow over highest tops where night temperatures may dip just below freezing. However, warmer air pushing north on Friday will bring wet weather to much of the Highlands with unsettled conditions extending southwards over the weekend.
