After a brief milder interlude at the back end of last week, the cold weather is returning with a vengeance.
With increasingly cold air flooding across the UK, any precipitation will readily turn to sleet and snow.
It's not just wintry showers that we need to watch out for.
Forecasters have highlighted two main snow events on Tuesday and Thursday affecting large areas of the UK in the next few days, bringing with it the likelihood of traffic and travel disruption due to ice and snow.
Met Office warnings are in force and you are strongly advised to keep up to date with the very latest forecasts on this developing situation.
Rain, sleet and snow showers will become more frequent in northwestern areas during the evening and overnight, with some icy conditions. Largely dry elsewhere with clear spells and widespread frost.
Wintry showers will continue in northern Scotland. Elsewhere a band of rain, sleet and snow will move eastwards through the day and overnight, bringing accumulations in some places.
Wednesday to Friday
Snow in eastern England gradually clearing on Wednesday. Staying cold with wintry showers, mainly around coasts, and possibly longer spells of rain/snow. Widespread frosts likely, with a risk of ice.
