Mourners face a "less than 10% chance" of waiting in the rain to see the Queen's coffin, according to weather forecasters.
People in Edinburgh will be able to view the coffin at St Giles' cathedral from 5pm on Monday, where it will remain for around 24 hours until it is taken by RAF plane to London.
The late monarch will lie in state for four clear days in Westminster Hall, arriving there in the afternoon of September 14, until 6.30am on the morning of her funeral, a senior palace official said.
