The sun is set to shine this week with temperatures soaring to highs of 18C today.
Dry and sunny conditions will develop throughout today as forecasters expect daytime temperatures to hit highs of between 12C and 14C across eastern and northern coasts, while the rest of the country enjoys highs of between 15C and 18C.
Met Éireann forecaster Linda Hughes said today will be the best day for warm temperatures and sunshine.
"It is really looking like it's going to be the best day of the week ahead and it will be dry across the country.
"There will be an easterly breeze, though, so along the east and north coast that's going to keep the temperatures down to about 12C to 14C, but then across the rest of the country it's a pretty warm day with highs of 15C to 18C, so it will feel pleasant in the sunshine," she said.
Tonight will be dry in most areas with overnight lows of 4C to 8C.
However, the good weather will be interrupted as the forecaster said tomorrow will see heavy rainfall across parts of Munster and Leinster.
The wet weather will ease later in the day as temperatures will rise to between 10C and 13C in southern and eastern areas, and 14C to 16C in the midlands and west.
Temperatures will surge again over Wednesday and Thursday with forecasters anticipating afternoon highs of between 12C and 16C and potentially 17C or 18C in some central regions of the country on Thursday.
"Going into the middle of the week and towards the end of the week it will be a south-easterly airflow so there will be some outbreaks of rain in the south and the west mainly.
"The rest of the country is going to see a good deal of dry weather through Wednesday and Thursday," Ms Hughes said.
South-east breezes may bring outbreaks of showery rain especially to southern, western and south-eastern counties.
