Temperatures could hit their highest levels so far this year over the weekend, Met Éireann has said.

The mercury is forecast to hit 21C over the weekend as much of the country enjoys sunnier weather after an unsettled period.

The highest temperature reached so far this year is 21.2C, recorded on 1 April at Valentia, Kerry

While today is to be dull and misty in the eastern half of the country, it is to be drier and brighter in the west, where temperatures are forecast to reach 18C.

Tomorrow will be a "very mild or warm day" with good sunny spells forecast, although the forecaster has also warned of isolated showers.

Temperatures are forecast to reach 21C in inland areas.

The warm weather is forecast to continue into Sunday and the early part of next week, with highest temperatures of 19 to 21C forecast for Sunday.

Highest temperatures on Sunday are expected in the midlands and east in the best of the sunshine, whereas areas further west and southwest will see cloudier skies and temperatures not quite as high.

So far it has been a cooler May than usually, with Met Éireann saying that many weather stations have reported daytime temperatures 2C below the monthly average.
