Most places will be wet early on Sunday morning with scattered showers throughout Ireland.
The good news is that the cloud is expected to clear early with most places having a dry day with some good sunny spells and temperatures between 16 and 18 degrees.
However, cloud will spread from the Atlantic during the late afternoon before clearing overnight and early on Monday.
Monday afternoon, though, is predicted to be dry and warm with temperatures possibly reaching the mid-20's in the east of the country.
This period of warm weather is set to continue through to Thursday before, typically, the rain is due to return in time for the weekend.
