On Tuesday, snow showers will affect parts of the county, in some places adding several centimetres to existing accumulations.
Showers may fall as sleet near the coast and ice will be a hazard across the county.
On Wednesday, the east of the county will still see a few more centimetres of snow to any existing accumulations.
The very cold temperatures overnight any thawing of the snow by day will lead to icy stretches overnight through Thursday.
Lincolnshire County Council said its gritting teams will treat the major roads and routes across the county overnight.
