A weather warning for icy conditions on Norfolk's roads rhas been extended until Thursday morning.

The Met Office issued a yellow weather for ice across Norfolk and Suffolk from 4pm yesterday (Tuesday, January 22), initially until 11am today (Wednesday, January 23).

But they have now issued a fresh yellow warning for ice from 6pm tonight until 11am tomorrow.

The alert said that ice was likely to form on Wednesday night into Thursday morning, warning of the risk of falls on icy surfaces and ice on roads, pavements and cycle paths.

Norfolk police had warned people heading out on to the region's roads to drive carefully.

Snow and sleet showers hit the UK on Tuesday, including in some parts of Norfolk.

Dan Holley, forecaster for University of East Anglia-based Weatherquest, tweeted that wintry showers - a mixture of rain, hail, sleet and snow - would continue to affect coastal areas, especially the east coast.

And he said there could also be the odd rumble of thunder, which could lead to the weather phenomenon known as thundersnow, which is when a storm involving thunder and lightning also brings snowfall.

Forecasters say temperatures could drop to -3 or -4 degrees celsius this evening.

The Met Office says, although the weather will warm slightly towards the end of the week, more cold weather is set for the weekend.

The spokeswoman said: 'Gradually some slightly warmer air will push in for the latter part of the week, but we have a band of rain pushing in Saturday which will push much colder air in behind it.'
