The Met Office has issued a yellow weather warning for ice across parts of Shropshire, which runs from until 10am on Monday.
Temperatures around the county are set to drop down to around 2C tonight, although forecasters warn it could feel more like -2C in some places.
In its warning, the Met Office said wintry showers were set to develop during Sunday afternoon and evening. It went on to say: "Clearing skies later in the night are expected to lead to ice developing on untreated surfaces."
Showers will mainly fall as rain at low levels, but could turn to snow in heavier or more prolonged showers in higher areas.
The weather warning covers most of Shropshire, with only some parts in the south of the county, not included. The whole of Mid Wales is also included in the warning.
Temperatures are set to dip below freezing later in the week as the cold snap continues.
On Monday and Tuesday nights forecasters expect it to go down to -3C in many parts of the county, with warnings that it could feel as cold as -6C in places.
In its forecast for the week, the Met Office added: "Remaining cold with frosty nights to come. A mixture of sunny spells and showers," before temperatures get milder again on Thursday.
