Mostly cloudy in Belfast and Dublin with temperatures around 16 or 17C; similar temperature expected in Galway tomorrow in partly sunny conditions.
Llanelli will see periods of clouds and sunshine in about 18C on Sunday for Munster's visit.
Ulster are the first Irish team in action this weekend as they welcome Benetton to the Kingspan with both teams defending 100% records.
Dan McFarland's side, courtesy of bonus-point victories over Glasgow and Zebre sit second on the table, just shy of Munster on points difference.
The Treviso side, meanwhile, have two narrow wins to their name so far, a 22-18 success over the Stormers and a Munster-esque last-gasp dropgoal victory over Edinburgh.
This game will be notable as Rob Herring earns his 200th provincial cap for Ulster, while former Pro14 top try-scorer Rhyno Smith makes his first start at full-back for Benetton.

Ulster have not been beaten by Italian opponents since losing to Zebre in September 2017 and their only previous defeat to tonight's visitors came back in 2011.
Benetton have never won the opening three matches of the season but neither have they won a game outside Italy since March 2020.
Their last clash with an Irish province ended in a 20-12 home win against Connacht and they have never won successive matches against Irish opponents.

Champions Leinster host Zebre off the back of a most underwhelming 7-6 win away at Dragons last Sunday.
The performance of Leo Cullen's men was all the more surprising following their dynamic outing in round one when they beat the Bulls 31-3.
The Italians have lost both of their games so far, going down at home to the Lions and to Ulster last weekend.
The hosts have a formidable record against Italian opposition and their only defeat in such fixtures came at home to Benetton in April 2018.

Leinster have won their last three home matches since they were beaten 27-3 by Munster in Dublin during the Rainbow Cup and they prevailed 48-31 when these sides met in Parma in March.

Connacht were the most impressive in last weekend's clean sweep, putting the Bulls away 34-7 in the Sportsground.
After falling to a heavy defeat in Cardiff on the opening day, the bonus-point win was much needed out west.
Following two rounds, Connacht are joint top of the team charts in clean breaks (13) and defenders beaten (44) with Mack Hansen accounting for 15 of those defenders.

The Westerners are bidding to win three home championship games in a row for the first time since October 2019.
The Dragons, meanwhile, are hoping to snap a run of six straight defeats since beating the Scarlets 52-32 in the Rainbow Cup in April.

Table toppers at the end of round 2, Munster go out for their first road trip looking to make it three from three.
A six-try victory over a hapless Sharks side was followed up by a bizarre win over the Stormers as Munster came from 15-0 down to eventually prevail 34-18, all five tries coming from their pack.
Scarlets, meanwhile, lost their opener to Edinburgh, 26-22, and beat the Lions 36-13 last time out.
They have lost just one of their last six home matches across the Pro14, Rainbow Cup and United Rugby Championship.
