Holders Galway will face Roscommon in the FBD League final after a comfortable 3-6 to 0-8 win over Leitrim in Clonbur.
It will be the third year the two counties have met in the decider after Roscommon overcame Mayo 0-14 to 0-11 in their round three fixture.
Two first-half goals set Galway up for their win in difficult conditions. A goal from Dessie Conneely was followed by another from a Frankie Burke penalty before Leitrim hit a purple patch to put together a run of seven points. However when Conneely added his second goal, Galway led by 3-3 to 0-7 at half-time.
With conditions worsening, Galway tacked on another three points to secure the win.
Manager Kevin Walsh described the conditions as "absoluetely shocking" which contributed to a huge number of handling errors, but thankfully no injuries.
Both Galway and Roscommon are due to meet on Sunday, and then again in the final scheduled for February 18. As a result there are calls for this weekend's round five fixture to also double up as the final - a decision to be made by the Connacht council.
