Additional fixtures have been arranged for Wolverhampton on Tuesday and Ayr on Wednesday due to the present cold snap playing havoc with the racing programme.
The BHA, in conjunction with the Levy Board, has authorised a seven-race card at the Dunstall Park venue. The races will close at noon on Saturday, while declarations must be made by 10.00 am on Sunday. The meeting is scheduled to run from 2pm to 5.10pm.
Although many parts of the country are currently covered by snow, Ayr remains raceable, prompting the BHA to bring in an extra meeting there, too.
The Scottish track's clerk of the course Emma Marley said: "With racing caught in the grip of snow and frost which has swept the rest of the country, we are delighted to be in a position to stage an additional fixture."
Entries for the six-race card will close at noon on Saturday, with declaration time 10am on Tuesday.
Tuesday's jumps cards are already under threat. The fixture at Leicester is in grave doubt, with officials admitting it would take "a miracle" for it to survive, while officials at Wetherby will hold an inspection at 11am on Sunday to assess prospects.
The West Yorkshire venue is covered with snow and clerk of the course Jonjo Sanderson is pessimistic about the chances of the fixture beating the elements.
He said: "We have a covering of snow. It's not heavy, but it's no longer light. We are also frozen in one or two places and there is further snow forecast for any time from tonight until Sunday.
"The daytime temperatures are only zero and the night temperatures are around minus 1C. There is not enough optimism in that forecast to suggest we'll be racing on Tuesday, I'm afraid."
Leicester clerk of the course Jimmy Stevenson has called an inspection for 9am on Sunday. The course is covered by two inches of snow and with parts of the turf frozen underneath, Stevenson believes the meeting has little chance of surviving. He said: "It's not looking good. It needs a miracle."
