The weather warnings carry a medium likelihood, and caution that injures may arise from slips and falls in icy conditions, with journeys potentially delayed due to longer travel times.
It comes as a cold health alert was announced by the UK Health Security Agency (UKHSA), covering central and northern areas, and running from today until 8am on Monday.
It warns vulnerable people could be at greater risk and possible "minor impacts" on health services due to increased demand.
Cold weather has already brought road closures to northern England, with the A66 closed between Bowes in County Durham and Brough in Cumbria because of "concentrated snowfall".
National Highways said: "Crews are on scene with winter treatment vehicles working to clear and treat the carriageway, however forecasts predict that snowfall will continue in the area throughout the morning."
The Met Office said an Arctic maritime air mass has brought in the colder conditions.
