A cold snap warning for the next few days has been issued, with Arctic winds and even snowfall in places.
Winds will become increasingly northerly with temperatures expected to fall to below freezing on Tuesday night across large swathes of the country, according to forecasts.
Unseasonally cold temperatures will be accompanied by wintry showers on the east coast and in Scotland with hail, sleet and even snow on high ground.
Day time temperatures are expected to fall to between 7C and 10C (45F to 50F) in the south on Wednesday with temperatures in Scotland and on the east coast of between 5C and 8C (41F to 46F)
Winds will turn more westerly from Thursday with unsettled, warmer weather on the way.
"It is going to be pretty cold over the next few days as the winds turn round more to the north and low pressure moves away eastwards into Scandinavia," said Billy Payne, forecaster with MeteoGroup, the weather division of the Press Association.
"We are going to have some showers spreading from the north. Some of these showers could be wintry, most especially around the east coast and across Scotland, especially on high ground.
"We are talking about hail and sleet and some snow on the high ground, especially over the Scottish mountains."
