A Met Office weather warning for snow has been stepped up, spanning three days and the entire county.
The warning, which comes just weeks after heavy snowfall caused travel chaos in the county, is in place from 3pm on Friday all the way through to midnight on Sunday.
People are being warned to expect delays to travel and the possibility of power cuts.
The Met Office forecast reads: “A band of rain and hill snow will increasingly turn to snow through late Friday afternoon and evening. As this band moves south-westwards, ice will form in places where skies clear.
“Some roads and railways are likely to be affected with longer journey times by road, bus and train services. Icy patches are likely on untreated roads, pavements and cycle paths.
“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 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.”
The Lincoln 10K is still planned to go ahead as of the morning of Thursday, March 15. Participants will receive text and email alerts should organisers deem weather conditions to be too dangerous on the day.
