Met Éireann is still predicting a 27C scorcher this week, despite heavy rainfall and the absence of clear blue skies this Monday.
The Irish meteorological service has warned of scattered showers beginning in the east of the country and spreading westward, with heavy and thundery falls expected in some parts, as well as the potential for spot flooding.
Despite the wet start to the week, the national forecaster has pinpointed when the 27C hot blast will begin.
