From midnight tonight (Tuesday) until 4am, snow and sleet can be expected across the region - including in Norfolk.

But Norwich-based forecaster Weatherquest says only some of it will stick, mostly on grass verges and fields.

Instead the biggest danger to drivers on Wednesday morning will by icy conditions on the roads.

Temperatures are forecast to drop to -2C tonight in some parts of Norfolk, although it is the west of the county that will experience the coldest conditions.

Weatherquest's Phil Garner said it is likely to be 'quite icy' in the morning.

Norfolk County Council's gritting team could make as many as three journeys out onto the roads tonight to ensure they are adequately covered.

Any snowfall tonight will be caused by a weather front that is moving in from the west.

As temperatures drop, the rain will turn to sleet and snow.

Mr Garner said there will be no snow on Wednesday, but temperatures will fall again in the evening to about -4C.

Meanwhile, the Met Office has issued a yellow warning for snow and ice across the region, which begins from 3pm on Thursday and continues until 12pm on Friday.

Thursday's weather warning says a fresh band of rain and snow is expected to move in from the south west, which is likely to fall as heavy rain in the south west but could turn to snow as it hits cold air over the rest of the country.

The Met Office said: 'There is a chance of 2-5cm of snow for come places, timings are currently uncertain.'

Meteorologists also warned of ice becoming a hazard on untreated roads and pavements on Thursday night and early on Friday as temperatures fall below freezing. The Met Office said there was a chance of travel delays and disruption to rail and air travel.

With temperatures predicted to go below zero throughout the week Norwich City Council has activated its Severe Weather Emergency Protocol (SWEP) for those sleeping rough or at risk of homelessness.

Dan Holley, of Weatherquest, tweeted a video hoping to answer some questions about the potential incoming snowstorm.

In previous tweets he said the question of whether the region got snow or rain was 'very finely-balanced' and that there was a 'very low risk' of deposits of more than 5cm, as some forecasts are suggesting.
