TEMPERATURES are set to plunge tomorrow as Britain experiences a short, sharp cold snap.

Snow and sleet showers will fall over Scotland and Northern Ireland before moving down into Cumbria and north-west England in the morning.

The weather front will continue to travel down the west side of the UK through the day, reaching Wales and the West Country by the evening.

Temperatures will plummet across the nation - for example, Exeter in Devon will go from a high of 12C yesterday to a maximum of 6C today.

It will be particularly cold and clear overnight tonight, meaning much of Britain will wake up to an icy start tomorrow morning.

There is little chance of snow in Suffolk, and Wednesday will become milder and wetter.

The Highways Agency is advising drivers travelling north to check weather forecasts and road conditions, prepare for their journey and delay travelling if the weather becomes severe.
