An area of low pressure that has been approaching the UK from the west will become slow moving, swirling around and throwing areas of wet weather across the country.
A band of rain sweeping eastwards on Friday night will clear during Saturday morning, leaving a day of sunshine and showers.
Some of the downpours will be heavy, with the chance of hail and thunder.
Snow will mix in with some of the showers across very high ground in northern England and Scotland, above 600m (2000ft) elevation.
However it will not be raining all the time, with dry interludes between the bursts of rain.
It will be windy, especially around western coasts where gales are possible, adding to a chilly feel.
Maximum temperatures will range from 8 to 14C (46-57F).
