Lincolnshire snow causes disruption
About 60 schools have been closed in Lincolnshire after up to 5cm (2in) of snow fell on Sunday night.
Lincolnshire County Council said gritters had been out all night and snow ploughs had been used to keep roads clear but some were still icy.
Police said the A15 was still "treacherous" with several accidents in the morning.
Alan Aistrup, from the council's highways department, said: "All main routes are passable with extreme care."
He said the council had been gritting all night and farmers have been helping out with snow ploughs to keep the roads clear.
There have been problems on the A16 at East Keal near Spilsby and in the Wolds with lorries struggling to get up hills.
Flights at East Midlands Airport resumed at 14:05 GMT after poor conditions closed the runway on Monday morning.
Passengers have been advised to check with their airline for updates.
