Ms Sturgeon has previously said she hopes mainland Scotland will be able to move to Level 1 – the second lowest in the five-tier system – from June 7.
But a recent spike in infections has forced ministers to keep the entire Glasgow City Council area under Level 3 restrictions – meaning bars and restaurants can not serve alcohol indoors and get-togethers inside people’s homes are also barred.
Ms Sturgeon has already warned that Glasgow may “have to be in Level 2 for a couple of weeks before it moves to Level 1”.
She is due to reveal if the move to Level 1 can go ahead in a statement to MSPs at Holyrood on Tuesday afternoon.
Will Scotland move to Level 1?
A number of Scottish islands are already in Level 1, and Ms Sturgeon said she remains “really optimistic” that there could be a similar easing of restrictions on the mainland as planned.
But she added: “Given that Glasgow is in a different level right now, I think it would not be an unreasonable assumption that it might also have to be in Level 2 for a couple of weeks before it moves to Level 1.
“That’s an assumption at the moment, I will make these decisions on the basis of the up-to-date data.
“And of course the purpose of the levels system is that while yes, we want the country if possible all to be in the same level, it allows us to have that regional variation, so we’re not holding back the Highlands because Glasgow has an outbreak.
“I can’t rule out at any stage, particularly given we’re seeing some areas with higher levels than others right now, that there will be a variable decision on Tuesday.
“But I hope and remain really optimistic that we will stay on that forward track overall as a country.”
Yousaf to open Holyrood debate
Following the announcement today, Health Secretary Humza Yousaf will open a parliamentary debate on Scotland’s recovery from the pandemic.
He said: “The NHS and our wider health and social services have adapted at a phenomenal speed and scale to meet the challenges of this pandemic, whilst maintaining exceptional standards of delivery.
“We must help those services and staff to adapt further, as they continue to respond to Covid and face pre-existing non-Covid challenges.
“We will lead Scotland’s recovery with an ambitious recovery plan that ensures our NHS addresses both mental and physical health, as well as the aspects of wellbeing that have been affected by the pandemic.
“I have committed to work cross-party, and will produce our National Recovery Plan within the first 100 days of the new Government.”
How to watch?
The First Minister is expected to give a statement to MSPs shortly after 2pm.
The statement will be broadcast the BBC and also streamed on The Scotsman and the Scottish Government Twitter feed.
