The warning will span over the next two days.
Status yellow high temperature warnings have been issued for the midlands from Met Eireann for the next two days.
There's an alert for Leinster, Cavan, Monaghan, Roscommon and Tipperary from midday tomorrow - which will run until 6am on Saturday.
That will then be replaced with a similar warning for the country which will be in place from midday on Saturday until 6am on Sunday.
Met Eireann is warning day time temperatures will exceed 27 degrees - while nighttime lows will stay above 15 degrees.
Alan O'Reilly from Carlow Weather, thinks yellow weather warnings need to be scrapped:
