Schools in West Yorkshire have a further day of closures after a second night of heavy snow in places.
In Bradford, the city council said all of the district's 197 schools would be closed for the day. Dozens of others across the county remain shut.
Leeds City Council said it was down to head teachers to decide whether to open.
The Met Office said clearing skies would bring a risk of widespread icy stretches on untreated roads.
Chief executive of Bradford Council, Tony Reeves, said the decision to close the city's schools was taken on Monday because of the "very severe weather forecast".
He said: "This decision has not been taken lightly, but it is in the best interests of both children and parents to ensure their safety and to allow parents to make child care arrangements, including informing their employers where necessary.
"It is schools being closed at short notice which causes most disruption to residents and the economy."
Up to 30cm (11in) of snow fell on higher ground overnight, with the heaviest in Pennine areas.
Heavy snow fell at Leeds Bradford Airport but the runway was expected to be open from about 0900 GMT.
Extra beds were set up at hostels across West Yorkshire for travellers unable to get home. The St George's Crypt hostel in Leeds was filled to capacity.
Emergency services reported no major incidents overnight and all major routes are open.
On Monday, the bad weather forced the closure of more than 300 schools across the county.
