RTE weather woman Joanna Donnelly has warned there will be "extreme uncertainty" over the coming days as Ireland is set to be hit with both cold air and the European heatwave.
Met Eireann have forecast temperatures to reach up to 26 degrees on Friday in parts of Leinster and Munster but it will only reach the mid-teens near the west and northwest coast.
Joanna explained this is because Ireland is "on the border" between a clash of cold air from the north and heat from the south.
