Ice will develop fairly widely on Wednesday night into Thursday morning, with partially thawed lying snow refreezing readily. In addition, wintry showers across Orkney and northeast Scotland will slowly clear away to the east, whilst a new band of mainly light rain, sleet and snow will arrive from the west. Snow will fall to low levels at first away from coasts before becoming confined to ground above around 300 metres. 1-2 cm of fresh snow accumulations are possible in places, with 2-5cm of fresh snow accumulations on ground above 200-300 metres, mainly in western Scotland and hills northern England.
