The First Minister is due to give a statement to MSPs in the Scottish Parliament on Tuesday afternoon.
She has already indicated a change in the rules on outdoor meetings – which at the moment only allow for two people from two different households to get together – could be coming.
On Friday, Ms Sturgeon indicated “good progress” with the vaccination programme and the falling number of infections could mean that “greater normality is firmly on the horizon”.
She said then she was “hopeful” the Scottish Government may be able to make some “relatively minor, but I think important, changes in our ability to meet outdoors and also how young people are able to interact with their friends outdoors”.
Deputy First Minister John Swinney confirmed on Monday any changes to the current lockdown regime would be set out by Ms Sturgeon.
He added: “The First Minister has been clear that we will try to relax lockdown as quickly as we possibly can do, but we have to do it in a sustainable manner.”
The easing of lockdown restrictions began in February when children in the first three years of primary, as well as nursery youngsters, were able to return to the classroom.
Older primary children are expected to return to school full time from next Monday, March 15 – with secondary school pupils also to get some time back in the classroom from this date, before returning full-time after the Easter holiday.
