Hopes that summer had arrived have been dashed, with rain, plummeting temperatures and even hail expected in the coming days.
However, there is light at the end of the tunnel, and some warmer temperatures, with milder conditions set to return next week.
Today will see heavy showers throughout the country, Met Eireann forecaster Joanna Donnelly said.
"It will stay cold for the next few days, with rain and heavy showers widespread throughout the country," she said.
Tonight will be mostly dry as showers die out and temperatures will dip to zero as grass frost settles in.
There is no indication of warmer weather yet as cold and wet conditions are set to continue throughout the rest of the week.
More blustery wind is in store for tomorrow, as well as frost.
Saturday will bring scattered showers but also some sunny spells and temperature highs of 10C to 13C.
However, higher temper- atures are set to make a return early next week when summery weather will be the order of the day.
"On Sunday, temperatures will start to recover and see highs of 13 and 16 degrees," Ms Donnelly said.
