Starting out sunny today, the weather will turn dull and damp later on during the weekend, according to Met Eireann.
It will be mostly cloudy at first today with the chance of patchy drizzle in the west and north-west for a time, the national meteorological office says.
Any patchy drizzle will clear during the afternoon and cloud will gradually thin and break allowing sunny spells to develop in many areas.
It will be mostly dry overnight with clear spells and a few patches of mist. Minimum temperatures will drop to 5° to 8° in light southerly or variable winds.
Met Eireann expects moderate to good drying in many areas over the next few days, but poor in any drizzle this morning; drying will be poor due to rainfall on Sunday and Monday, improving somewhat on Tuesday and Wednesday next week.
Drier weather and light winds should be a positive for spraying over the next few days.
Field conditions have improved and will continue improve up to Sunday but, with the heavy rainfall expected Sunday into Monday, they will deteriorate somewhat.
Tomorrow
Tomorrow (Saturday, May 19) will be dry and sunny in most areas. However, cloud will gradually build across the western half of the country later in the day. Highest temperatures will range from 16° to 20° with light southerly breezes freshening later.
Then outbreaks of rain will affect much of the western half of the country by morning. Lowest temperatures will drop to 9° to 11°, with light to moderate southerly winds.
Outlook
Sunday will be generally rather dull and damp with patchy outbreaks of rain. Temperatures will range between 14° and 16° with light to moderate southerly winds.
Later in the day the winds in the west of the country will veer to the north introducing cooler weather there. Overnight temperatures will range between 7° and 10°.
