The cooler air will sink southwards Saturday and into Sunday
Colder weather is on the way for the next few days.
The cooler air will sink southwards bringing chilly days and frosty nights for many areas.
The airflow will be over the entire country by Saturday and into Sunday.
Met Éireann say it will stay cold "well into next week", with further frosts and perhaps the odd wintry shower.
Overall, there will be a lot of dry weather though, with bright spells of sunshine in mostly moderate northerly breezes.
But rain and hail showers will frequent over northern and northwestern counties and along Atlantic coastal fringes.
There will also be a few wintry flurries possible for higher ground, with showers more isolated elsewhere.
It will be cold throughout the weekend, with a widespread frost by night and maximum of only 6 to 9 or 10 degrees Celsius.
Sunday will also see moderate to fresh weather inland, but very blustery near coasts with wind chill.
