Wednesday night: Persistent rain, heavy at times, will continue to slowly extend from the northwest, bringing the chance of localised flooding, especially for Atlantic coastal counties. However, some southeastern areas will stay dry until morning. Moderate to fresh south or southwest winds, stronger near exposed coasts, will gradually becoming moderate to fresh for the southeastern half of the country, and light to moderate westerly elsewhere. Lowest temperatures of 8 to 12 degrees generally, milder for some southern and eastern areas.
Thursday: A wet morning with fairly widespread rain, heavy in places with localised flooding, especially in Atlantic coastal counties. Moderate to fresh southwesterly winds in the south and east will ease through the morning as light to moderate westerly winds become more widespread and a clearance to sunny spells and some showers move into the northwest.
