A dry spell early in the week is set to be replaced by heavy rain and wintry showers, according to Met Eireann.
It is set to be dry in most areas this morning, Monday. It will be mostly cloudy, but isolated patches of drizzle may affect western coasts and hills.
Some sunny breaks will come through too further inland and in the east. Temperatures could reach highs of between 8º to 11º in light south-west breezes.
Meanwhile, all soils are at field capacity presently – with some waterlogging in certain areas, according to Met Eireann. However, many grounds are trafficable, it added.
Tomorrow, Tuesday, is forecast to be cloudy and breezy. A good deal of dry weather is likely through the day, but occasional spells of misty drizzle or light rain are also possible.
There is a danger that western coastal areas could have spells of more persistent rain through the day. Temperatures will vary from 9º to 10º. Little change is expected overnight and there will be no frost.
On Wednesday, there is a risk that heavy rain will become widespread through the day. This rain is set to continue during the evening and night.
In some northern counties, there will be a possibility of this rain turning to snow overnight, as winds turn north to north-east in direction. The rain will finally clear along the south coast by dawn, Met Eireann added.
A frosty start is forecast for Thursday morning. It will be cold and bright for the day, with fresh northerly winds and highs of 4º to 6º.
The cold and frosty conditions are expected to continue on Friday, with temperatures reaching between 3º and 5º. It will be bright during the day, but further wintry showers will be possible over Ulster, Connacht and west Munster.
