A hot and humid Tuesday is in store for Ireland - but some areas may still be hit with thundery showers.
Met Eireann has predicted a cloudy morning but says there will be sunshine over the afternoon.
However, scattered and heavy showers may develop in some areas, with Munster facing more thundery downpours. Highest temperatures will range from 19C to 23C.
A forecaster said: "Rather cloudy with patchy mist and fog at first today, Tuesday, but brightening up with warm sunshine coming through by the afternoon.
"Scattered showers will develop also though, and a few of them will be heavy or thundery, especially in Munster.
"Humid, with highs of 19 to 23 degrees. Winds will be mainly light northeasterly, moderate near Atlantic coasts."
There will be isolated showers on Tuesday night, but most places should stay dry. Lowest overnight temperatures will range between 10C and 14C.
The forecaster added: "Remaining showers will becoming increasingly isolated tonight and it will become mainly dry with clear spells.
"A few mist and fog patches will form towards dawn. Lows of 10 to 14 degrees in mainly light northeast breezes, moderate near some coasts."
The country is then in for its warmest four days of the year so far, as highs of at least 25C are expected up until Saturday.
Wednesday will be mostly dry, apart from some showers in the north and west, with temperatures as high as 25C.
Thursday will be warmer again as the mercury soars to a scorching 27C - but an "isolated thunderstorm" may hit the southwest.
Friday will be another hot and humid day with highs ranging from 20C and 27C.
However, Met Eireann says there is also "potential for thundery downpours to develop in these areas later in the day".
