There is a yellow weather warning for snow and ice in place for Ayrshire.
Forecasters say the weather warnings, which came into place from 4pm on Sunday and are due to stay in place until 11am on Monday may cause travel disruption and injuries from slips and falls on icy surfaces.
There are five yellow weather warnings in place for snow and ice covering the southern part of England, eastern Scotland and Northern Ireland.
Icy patches on untreated roads and pavements are likely, with journeys by road and rail likely to be affected.
But the Met Office said by next week temperatures are due to jump back up.

The wintry showers are expected to stretch across western Scotland and the Northern Isles, but were expected to turn increasingly to rain at low levels during the early hours of Monday - allowing icy patches to form.
Meanwhile, on Scotland's hills and mountains, showers will remain as snow.
According to the Met Office, a few centimetres of snow are possible on hills above 200 metres, and perhaps over the Shetland mainland for a time this evening.

Northern Grampian will be dry for most of the night but a few showers are likely late in the night.
