WEATHER
A few bright or sunny spells, especially in the east and north, but scattered showers also. Showers will merge to give longer spells of rain in west Munster during the day and also in west Connacht later, with a risk of thunder. There is a slight risk of thunder in the north also. Maximum afternoon temperatures 19 to 23 Celsius, in mostly moderate southeasterly winds, but winds will be fresh to strong and gusty along western and southwestern coasts. For more go to met.ie
Permutations
It's relatively straightforward in Group 2. Tyrone and Dublin are already through to the All-Ireland semi-finals. Cork and Roscommon have only pride to play for on Leeside.
Because of Dublin's superior points difference, a draw in Omagh will be enough for them to top the section. Tyrone must win if they are to finish ahead of the Sam Maguire holders and get their booking at Croke Park on Saturday next.
It's a phoney war alright
The much anticipated prospect that Tyrone and Dublin would remain unbeaten at this juncture has come to pass. Of course both camps know their semi-final opponents are Mayo after last night's win over Donegal. Will that alter the thinking as regards team selections?
Mickey Harte has made 15 changes to the side that defeated Cork, while the Dubs show eight changes from the side that steamrolled Roscommon a fortnight ago. That said, it's a strong enough side.
Diarmuid Connolly is part of their match-day squad and any appearance from the St Vincent's clubman is sure to garner most of the headlines, irrespective of the outcome in Omagh.
Rory O'Carroll's first start of the year for the Dubs and the inclusion of All Star Padraig Hampsey and Tiernan McCann in the Tyrone team should also generate interest. Yet, on this third last weekend of the championship, we have a dead-rubber involving Cork and Roscommon and a side that have all but conceded defeat, namely Tyrone.
Of course, Mickey Harte is only doing what he thinks is right for his side and clearly has one eye on Croke Park next weekend.
And because of that, we won't get the chance to see the championship's top scorer Cathal McShane (3-42), the player who caused Dublin no end of problems during that league clash at Croke Park back in March.
Not only does he know how to score, but the Owen Roes clubman is also unselfish in laying the ball off to the likes of Peter Harte and Mattie Donnelly. The latter, when alongside McShane in the full-forward line, is close to a perfect combination. The trio in question will not be called upon this weekend.

This afternoon's winner will face Mayo in the first of the All-Ireland semis next Saturday (5pm), with the loser having a date with Kerry on the Sunday at GAA HQ (3.30pm).
Tyrone: Benny Gallen; Ciarán McLaughlin, Pádraig Hampsey, Liam Rafferty; Tiernan McCann, Aidan McCrory, Michael Cassidy; Ben McDonnell, Declan McClure; Richard Donnelly, Kyle Coney, Conan Grugan; David Mulgrew, Connor McAliskey, Conall McCann.
Dublin: Stephen Cluxton; Rory O'Carroll, Davy Byrne, Philly McMahon; Eoin Murchan, Jonny Cooper, Robert McDaid; Brian Fenton, James McCarthy; Eric Lowndes, Cormac Costello, Brian Howard; Kevin McManamon, Eoghan O'Gara, Con O’Callaghan.
Did you know
This will be the 21st time that Mickey Harte has managed a Tyrone team in league and championship against Dublin. It's 10-7 in Dublin's favour, with three draws.
The 2008 All-Ireland quarter-final was the last time the Red Hand beat the Dubs in championship football - and a comprehensive win it was on a scoreline of 3-14 to 1-08 in the Croke Park rain.
Tyrone would ultimately go on to win Sam.
Pride at stake
On the third last weekend of this year's championship, we have this dead-rubber encounter as Cork welcome Roscommon to Páirc Uí Rinn. The possibility of such a contest was always there given the structure of the Super 8s, but it's not ideal. No doubt, any rethink of the summer landscape will that into account after the end of the 2020 season.

Cork are in better shape heading into the clash on Leeside and will be looking to end what has been a productive summer for them on a high. That will be viewed as a positive, after we all feared for their well-being following relegation to Division 3 in the spring.
Crucially for football in the county, the feel-good factor is back with the U17s and U20 enjoying good summers.
Cork boss Ronan McCarthy has made four changes from the side that loss to Tyrone.
Goalkeeper Micheal Martin, defender James Loughrey and forwards Eoghan McSweeney and Paul Kerrigan come win - with Mark White, Liam O'Donovan, Tomas Clancy and Brian Hurley making way.
Cork: Micheal Martin; James Loughrey, Thomas Clancy, Kevin Flahive; Sean White, Stephen Cronin, Mattie Taylor; Ian Maguire, Killian O'Hanlon; Eoghan McSweeney, Ruairi Deane, Kevin O'Driscoll; Paul Kerrigan, Mark Collins, Luke Connolly
Roscommon, after a bruising defeat to Dublin, will also be targeting a positive end to their season. They have found the going tough both this year and last in the Super 8s.
