After a bright start for many this morning, the weather is set to take a dramatic turn over the coming days, with Met Eireann issuing a weather warning for three counties. The national forecaster issued the weather alert for Cork , Kerry and Waterford at 11am this morning, with the southwest of the country set to be hit hardest by the heavy downpours forecast for later this week. The Status Yellow - Rain warning will come into effect for the three counties at 12am on Tuesday and will remain in place until 12pm midday. Issuing the weather alert, Met Eireann warned that ' persistent rain, heavy' showers will lead to localised flooding, difficult travel conditions and poor visibility on roads. According to the latest Met Eireann forecast, Tuesday will be a wet and blustery day, with the forecaster warning that the rain will be heavy at times with localised flooding. There'll be some mist and hill and coastal fog too, with highest temperatures of 12C to 15C, in moderate to fresh, occasionally strong, and gusty southeast winds veering southerly. Further spells of rain or showers are expected for a time on Tuesday night, heavy at times, but a clearance to drier weather with clear spells and just isolated showers will develop overnight. Lowest temperatures of 7C to 11C with southerly winds generally easing. Mist and fog patches will develop also. Any mist and fog will clear on Wednesday morning to leave variable cloud and a few bright or sunny spells. It looks as though further spells of rain could affect parts of the south and east with drier conditions and just the odd shower further north and west, with highest temperatures of 11C to 14C in light variable breezes becoming easterly later. The miserable spell will continue for the rest of the week and into the early parts of the weekend, with low pressure pushing up further spells of rain or showers expected on Thursday and Friday. Met Eireann has said there are early indications of potentially cooler and more settled conditions extending from the north through next weekend, however.
