Nine counties will see temperatures hit 21C or higher today as a sunny weather spell hits Ireland.
Dublin, Louth, Limerick, Tipperary, Offaly, Clare, Kilkenny, Longford and Laois will all enjoy the jump in heat, according to Met Eireann.
Plenty of other places like Cork and Kerry will reach 20C at times, but it won't quite be as warm as the aforementioned nine counties.
A Met Eireann forecaster said: "Cloudy today in many areas and patches of drizzle. Sunny conditions in the south of the country which will spread to other areas during the afternoon.
"Highest temperatures will range from 17 to 21 degrees, the best where long spells of sunshine develop, and it will be cooler along coastal areas. Light to moderate southwest breezes will become light variable later.
"Tonight will be largely dry and clear with light variable winds becoming light to moderate southwesterly later. Temperatures will fall to no lower than 9 to 11 degrees."
Tomorrow is set to continue warm and sunny with the mercury into the 20C range again in many parts of Ireland.
The Met Eireann forecaster added: "Tomorrow, Wednesday, will be mainly dry with good sunshine expected. Becoming cloudier in the west later with a chance of a little light rain or drizzle later in the west and northwest.
"Highest temperatures between 17 and 21 degrees, the best where the sun shines longest and a few degrees cooler on the east and south coasts. Southerly winds will be moderate to fresh, veering west and decreasing later.
