Dry this afternoon with sunny spells developing in the south and east. However, cloud will persist in parts of Connacht and Ulster, with a risk of coastal drizzle. Highest temperatures will range from only 10 or 11 degrees on northern coasts to 19 or 20 degrees in the southeast. Winds light to moderate, northwest to west.Tonight
Tonight will be mainly dry with broken cloud and some patches of mist or fog developing in the southwest. Lowest temperatures of 4 to 8 degrees, coldest inland in the south with mostly light, southwest breezes.
Tomorrow, Wednesday, cloud will thicken soon after dawn and outbreaks of rain will spread eastwards during the morning. The rain will become persistent in places around the middle of the day but a clearance to showers will extend from the west by evening. Southwest winds will freshen generally as the rain arrives, then winds will veer west with the clearance and will gust strongly in places for a time. Highest temperatures 11 to 14 degrees, several degrees cooler than normal overall.
Wednesday night will see showers becoming confined to coastal counties of the north and west while clear spells develop elsewhere. Moderate to fresh, westerly winds will persist and it will feel cold. Breezy and rather cool conditions will persist on Thursday also. Showers will tend to become more widespread during the day but all areas will have sunny intervals, while the south and southeast of the country will have only light showers. On Thursday night, however, showers are likely to persist as winds veer west to northwest. And there will be very little change for Friday, with widespread, locally heavy showers, fresh and gusty west to northwest winds, and temperatures well below normal for the end of May. However, showers will die out on Friday night, winds will ease and it may become cold enough for slight grass frost to occur.
Saturday will be dry and bright for the most part during daylight hours but cloud will increase from the west going into the evening, before a band of rain spreads eastwards to all areas during the evening and early night. The rain will clear overnight leaving the early part of Sunday dry and bright but rather cool. Then, during the second half of Sunday, it is likely to become cloudier, with outbreaks of rain developing in the west later. Overnight into Bank Holiday Monday there are signs that it will become rather windy and wet, with the likelihood of a spell of heavy rain in most areas. During Monday, the rain will clear to showers but it will stay quite windy, with temperatures much lower than normal everywhere. Temperatures will probably improve to some extent going into the middle of next week, at least in the south and east, but changeable conditions seem set to persist.
