However, the First Minister's address to MSPs in Holyrood may be delayed slightly if preceding parliamentary business runs over slightly.
On Monday, Ms Sturgeon said at the Scottish Government’s coronavirus briefing that rates in Greater Glasgow and Clyde and Lanarkshire health board areas are “stubbornly high”.
The First Minister suggested a “limited period” of the strictest measures – moving from Level 3 to Level 4 – could allow an easing around Christmas.
She said the prevalence of the virus is causing concern and could mean regional hospital and intensive care services may not be able to cope as winter continues.
“Stubbornly high prevalence means that we might have less flexibility to offer some limited and careful easing of restrictions over the Christmas period which we are very keen to do,” she said.
Under the toughest restrictions, non-essential shops will be closed, along with bars, restaurants, hairdressers and visitor attractions.
Schools will remain open, however, with the First Minister saying on Monday it is her “objective and intention” to ensure they do not close.
Ms Sturgeon’s address to MSPs will be broadcast live on BBC Scotland, as well as online on Scottish Parliament TV.
