Saturday begins chilly with wintry showers in the north and west. The rest of the day brings further showers to northern and western areas with many of them falling as sleet or snow over higher ground and down to lower levels at times. Southern and eastern areas have a good deal of dry and bright weather.

The GFS chart below shows low pressure to the northeast and high pressure to the west. The UK is sandwiched between under a cold northwesterly air stream.

Temperatures range from 2C (36F) in northern Scotland to 7C (45F) in the south and blustery conditions will make it feel very cold. See the rainfall and precipitation type radar for the latest view.

Tonight wintry showers continue in the north and west and there is a chance of a few showers pushing southeastwards. Quite a widespread frost develops. 

Tomorrow after a cold and bright start cloud begins to build from the west. During the second half of the day winds strengthen and outbreaks of rain spread into western areas. Over high ground in Scotland the rain readily turns to snow.

The chart below is for 18:00 GMT tomorrow and shows outbreaks of rain pushing into Northern Ireland and western Britain.

Cold next week with a risk of snow

Wet weather clears the south east on Monday to leave all areas with a mix of sunshine and showers. In the north it will be cold with the showers again turning wintry.

Through the rest of the week it remains cold. Wintry showers are likely on Tuesday, Wednesday and Thursday and at times they could fall as snow even at low levels. Most of them affect coastal counties but there is a risk of more organised bands of showers pushing inland.

By the weekend things become uncertain. High pressure to the west of the UK may start to decline allowing weather fronts to make inroads from the west. That would bring the risk of rain and snow as milder air gradually edges back in. There are also suggestions from some computer models runs of high pressure transferring to Scandinavia which could lead to a cold east or north easterly air stream.
