Met Eireann says the warm conditions will continue on Sunday and Monday when highs of 18C are expected.
However, temperatures will dip to below freezing during the week, with Thursday night set to be particularly chilly with lows of -3C.

Alan O'Reilly from Carlow Weather questioned whether "winter 2.0" is on the way in the days ahead thanks to the arrival of a cold snap.
Before then, Ireland can bask in another day of glorious weather on Sunday with early morning mist clearing to leave another dry day with long spells of sunshine.
There may be a few showers in the west and northwest later, with highest temperatures of 13 to 18C, coolest along the east and south coast, in light easterly or variable winds.
Sunday night will be mostly dry with clear spells, as any showers in the west and northwest die out.
Winds will be light and variable so patches of mist and fog will develop, with lowest temperatures of 1 to 5C generally but possibly dipping near freezing locally.
A forecaster said: "Any mist and fog patches will clear on Monday morning. Most areas will stay dry with sunny spells, however there will also be isolated showers. Highest temperatures of 13 to 17C, coolest along the east and south coast.
"Dry with clear spells [on Monday night]. Winds will stay light and variable so patches of mist and fog will develop overnight. Lowest temperatures of 1 to 5C.
