Gritters throughout the county have been in action for the third night in a row as Leicestershire continues to be gripped by an icy blast.
Snow has been predicted to fall in the county today as temperatures were not expected to get above freezing.
One of the first major casualties of this week's wintry weather was the Loros Twilight Walk, which was due to take place tonight.
The fund-raising event for the Groby Road hospice, which was due to see 1,000 women completing a 10km walk around Leicester city centre, has been postponed until next month.
Event organiser Christian Weikert-Picker said: "I am very disappointed that we have had to postpone the Twilight Walk. The decision has been made as the safety of our 1,000 female participants and 90 volunteers has to take priority over fund-raising.
"I apologise to all the ladies who were looking forward to the event, but very much hope they will join us on our new date."
The walk, one of the charity's biggest annual fund-raisers, which was due to start from the King Power Stadium, has now been rescheduled for Saturday, April 13.
Last year, it generated more than £50,000 for Loros, which supports about 2,500 patients and their families each year.
Holy Cross Catholic Primary School, in Whitwick, was the only school to be closed yesterday due to the cold weather.
Youngsters were told to stay at home but staff remained on site to meet pupils returning from a residential trip.
The Mercury could not reach anyone at the school for a further explanation as to why it was closed.
Both the county council and city council's gritters were out last night.
A city council spokesman said: "We gritted last night from 8pm covering all of our primary routes. The drivers worked through until 6am.
"The same arrangements are in place for Sunday and into Monday.
"We have got about 1,200 tonnes of salt left, and six lorries to cover 180 miles of primary routes."
Leicester Mercury weatherman Dave Mutton predicted the icy blast will last well into next week.
He said: "I am afraid to say the very cold east wind is with us for a while. It is going to dominate the weather, giving us very, very cold conditions well into next week.
"The only comfort I can offer readers is that it looks as though we could be in for a hot May and a flaming June."
