Dublin will enjoy one last blast of heat before a dramatic change will grip Ireland.
Summer weather is set to end with a blast as a possible "low system" could barrel across the country bringing with it "a lot of rain", Carlow Weather's Alan O'Reilly warned.
He said: "As I mentioned earlier a lot of uncertainty around next weekend with a risk of a low system coming close to or over Ireland. Latest GFS brings it down West and then back up over Ireland which could bring a lot of rain.

"This far out is very hard to call and it is likely to change. The ECMWF model shows a different path for the low and moves straight through Ireland with rain but not as much.
"Going to be very hard to forecast next weekend with this messy setup."
Today will start with any mist and fog clear to leave a dry day with sunny spells. It will be hazy at times and temperatures will be around 18 to 21 degrees.
Tonight will be dry and mostly clear at first but cloud will build overnight from the west. There will be some mist patches with the lowest temperatures of 11 to 13 degrees.
Tomorrow will be cloudy with outbreaks of light rain and drizzle at times and temperatures will be around 17 or 18 degrees. The evening will see mainly dry weather with isolated showers.
While there is no further forecast for Dublin, here is what Met Eireann's national outlook says:
Sunday night
"Mostly dry with variable cloud though there will be some showers, mainly in the northeast where they will be heaviest. Mild and humid with temperatures not falling below 10 to 15 degrees in mostly light easterly breezes.
Monday
"Good sunny spells and a lot of dry weather expected with just well scattered showers, though with the continued chance of a few heavy bursts. Highest temperatures of 18 degrees in parts of the east and northeast to 22 or 23 degrees in the west.
"Easterly winds will be light to moderate.
Monday night
"Another mostly dry and clear night. Temperatures not falling below 10 to 14 degrees in a light easterly breeze."
