A yellow rain warning has been issued for the entire country.
It came in to effect at noon today, and will remain in place until 10pm tonight.
Met Eireann says there is the risk of heavy thundery downpours.
These will be worst over Leinster and Munster, and may lead to some spot flooding.
Looks like we'll be needing the raincoats before the sun cream this week.
It will still be quite warm this afternoon, with temperatures hitting somewhere between 18 and 22 degrees.
