The Met Office has issued a yellow weather warning for snow and ice tomorrow across the area, which includes Stevenage, North Herts and Central Bedfordshire.

Temperatures could fall to -2°C or -3°C, with snow most likely in and around North Herts between 5am and 9am, and from 5pm onwards.

The forecast for Biggleswade and surrounds is similar, but there is currently a 60-per-cent chance of snow between 3am and 8am, and the same chance of it falling between 9pm and midnight.

The warning is in place from first thing tomorrow morning and throughout the day, and extends into Sunday too.

There is also an amber warning for heavy snow and ice further south – including central London – and covering parts of Essex and Kent.

On its website, the Met Office has said: “A band of rain will turn more widely to snow early Saturday morning followed by scattered snow showers through the remainder of the day. These showers may become more prolonged, particularly during the evening.

“Any melting of lying snow will lead to an ice risk on untreated surfaces on Saturday morning and night.

“Travel delays on roads with some stranded vehicles and passengers, along with delayed or cancelled rail and air travel is possible.

“Some rural communities could become cut off and power cuts may occur. Some injuries from slips and falls are possible on icy surfaces.”
