Pack the ponchos and wellies for the big match and Electric Picnic
The weather isn't going to play ball during Sunday's historic All-Ireland final, according to Met Eireann.
But if it's any consolation to the hordes of GAA fans who were unable to secure tickets for the historic showdown between Dublin and Kerry, those heading to Croke Park will be at risk of a mild soaking.
While it won't be a washout it certainly won't remain dry for the final, said Met Eireann forecaster John Eagleton.
"I wouldn't guarantee a fully dry day for the big match," he said. "But it won't be persistent rain."
For the 82,000 punters who were lucky enough to bag a ticket for the match - as well as thousands more expected to watch the nail-biting showdown on a giant screen at Smithfield - he advised they bring a jumper as well as rain gear.
Daytime highs are not expected to exceed 14C or 15C and there will be a bit of a breeze to keep things "on the cool side", he said.
Those heading to Electric Picnic should pack warm clothing as well as rain gear and wellies, he added.
The annual three-day music festival in Stradbally, Co Laois, is expected to start on a soggy note tonight when widespread rain moves into Leinster and Munster in the late evening.
Due to the high volumes of rain in the midlands over the past month, the ground will not be able to absorb much more water.
As a result "it might be a bit muddy underfoot", he warned festival-goers.
Those driving to Stradbally from the north and west are also advised to heed a status yellow rainfall warning affecting Connacht, as well as counties Donegal, Clare, Cork, Kerry and Limerick with between 30mm and 50mm rain forecast.
The weather warning is in effect from 6am today until 6am tomorrow.
Met Eireann is warning of heavy and persistent rain in the affected counties with a risk of localised flooding.
Mountainous areas are especially at risk of even more rain than that forecast.
Meanwhile, the rain will taper off to a mixture of sun and showers by tomorrow afternoon with highs between 15C and 18C with moderate west to north-west winds.
Sunday will be similar, although cooler, with daytime highs of just 14C to 17C.
Today, however, will be a reasonably pleasant day in Dublin and the rest of Leinster, with highs between 16C and 20C throughout.
Although rain will move into most areas by tonight, it should stay dry for much of Leinster and Munster during the day.
