He added: "The weather models are showing a late blast of cold Northerly air heading our way from Sunday for a few days!"
Met Éireann says: "Mainly dry on Sunday to start, afternoon showers will develop. It'll turn colder later as winds become northerly.
"Temperatures on Sunday between 9 degrees in the north and 14 degrees in the south then currently it looks like it could potentially turn frosty again overnight Sunday night as a cold northerly airflow becomes established.
"Current indications suggest a cold but mainly dry situation for the start of next week with rain arriving from the west midweek."
