“Turning very wet tonight [Saturday]. There will be clear spells and scattered showers at first, but more persistent showery rain, accompanied by thunder and strengthening southeasterly winds, will then sweep northwards over the country.
“The rain will be heavy in places, bringing a possibility of localised flooding. Lowest temperatures of 7 to 11 degrees. Becoming blustery in many areas, especially along eastern and northern coasts,” forecaster Conall Ruth said.
Heavy rain will clear northwards on Sunday morning, and the afternoon and early evening will be largely clear with just isolated showers but a further band of heavy rain will push in from the southwest as Sunday night approaches. Highest temperatures of 16 to 20 degrees.
Electric Picnic should also be aware of the possibility of high winds at times on Saturday night.
The weather is forecast to be very unsettled with wet and windy conditions predominant next week.
Sunday will be a breezy day with sunny spells and some scattered showers.
“By evening, a further band of heavy rain will push in across the southern half of the country and winds will strengthen. Highest temperatures of 17 to 21 degrees in fresh and gusty southeast winds. Rain will clear northwards overnight with clear spells and scattered showers following,” Mr Ruth said.
Early next week, the weather is likely to be mixed with scattered showers and sunny spells on Monday and Tuesday.
