The first snow of 2014 is falling heavily in Lincolnshire tonight.
Several centimetres have come down in the Wolds in the last hour, leading to hazardous road conditions.
Drivers are being warned to take care as temperatures fall over night.
"Weather conditions aren't exactly great. Please slow down, increase your braking distances and be aware of poor grip," the Lincolnshire Police road policing unit has tweeted.
The yellow snow warning for Lincolnshire issued by the Met Office today will remain in place until 6am on Saturday.
Conditions are less severe in Grimsby, with temperatures of around 3 degrees Celsius expected overnight.
However, the rain which has set in this evening is set to continue into the night and throughout most of Saturday.
