Wednesday will be a warm and humid day with temperatures of between 22 and 27 degrees in places, however, it will be a few degrees colder on northwestern coasts.
Showers will move across southern counties into the evening and tonight with heavy rain and thundery showers affecting Munster and south Leinster overnight.
