A wet start today with widespread heavy rain and the ongoing risk of localised flooding, especially over Leinster where it will also be rather windy.
It will be mild at first over much of Munster and Leinster with midday temperatures of 9 to 13 degrees Celsius, but quickly turning colder during the afternoon.
Much colder throughout the day over Ulster and Connacht, with rain possibly even turning to sleet for a time, and highest temperatures of only 3C to 6C degrees.
Rain easing into this afternoon across all but eastern counties. Southwest winds will veer northwest as the cold air sinks down into all areas.
The last of the rain will eventually clear eastern areas early tonight with drier clearer weather developing for a time everywhere.
West to southwest winds will however increase fresh and gusty overnight, as wintry showers feed down from the northwest later.
A few sleet and snow flurries possible over the hills and mountains of the north and northwest. Frost too, mainly for sheltered areas.
Lowest temperatures of 0C to 3C degrees.
