Rovers lost their opening game of the season but have since scored eight goals without conceding in back-to-back wins, while Cardiff have three points from the first nine on offer.
The Blue and Whites' 11 goals from their first three league matches is the most by a second-tier side since Middlesbrough scored 12 in 1963-64.
Tony Mowbray's men looked scintillating in their 5-0 win over Wycombe Wanderers and 4-0 victory at Derby County, coming on the back of a 3-2 reverse at the hands of Bournemouth.
Ewood Park is the last place Cardiff want to visit this weekend, then, having looked poor in a defensive sense so far this season.
City shipped three unanswered goals against Northampton Town in the EFL Cup first round and have lost 2-0 and 2-1 to Sheffield Wednesday and Reading respectively in the league.
Those home losses sandwiched an improved 2-0 win at Nottingham Forest in their first away league outing of the season, and it is City's away form that will offer Neil Harris hope.
The Bluebirds have won eight of their last 10 Championship matches on their travels, including a run of three victories on the bounce stretching back into last season.
Cardiff have a good record at Ewood Park, too, with their last league defeat there coming some 36 years ago. The last four encounters there between the sides have finished level.
Blackburn won the most recent encounter 3-2 in South Wales three months ago, with Adam Armstrong scoring what proved to be the winning goal 20 minutes from time.
Armstrong has carried that goalscoring form into the 2020-21 campaign, having now netted in his last five Championship matches and found the net seven times overall in that run.

Joe Rankin-Costello has been ruled out for Rovers after sustaining a hamstring injury in the win over Derby - a big blow for Mowbray as the right-back has started the season well.
That will likely mean Ryan Nyambe - a second-half substitute at Pride Park - slotting into an otherwise unchanged back four for the visit of Cardiff.
As for Cardiff, Callum Paterson was the latest player to depart the club this week, joining Sheffield Wednesday in a cut-price deal worth around £500,000.
Harris does still have different options to call upon in attack, with Lee Tomlin battling to be fit after a stop-start opening few weeks to the campaign for the playmaker.
Blackburn Rovers possible starting lineup:
Kaminski; Nyambe, Lenihan, Williams, Bell; Johnson, Holtby, Rothwell; Dolan, Armstrong, Brereton
Cardiff City possible starting lineup:
Smithies; Osei-Tutu, Morrison, Nelson, Bennett; Ralls, Bacuna; Murphy, Tomlin, Hoilett; Moore
We say: Blackburn Rovers 2-2 Cardiff City
Blackburn have scored goals for fun this season and enter this game in better form than Cardiff, although the Bluebirds do boast one of the best away returns in the division.
Given that the last four league meetings between the sides at Ewood Park have finished level, we are tipping the spoils to be shared on Saturday afternoon.
