Met Eireann has forecast a rollercoaster Sunday weather-wise - but happily midweek will start to look a bit more like summer.
The meteorological service said today will see a wet start, with outbreaks of rain in many places and some heavy falls.
This will clear to sunshine and showers from west to east this morning, with the rain clearing into the Irish Sea by early afternoon.
However, heavy showers will then follow that again, with a risk of thunderstorms and hail, forecasters said.
Highest temperatures are expected to be between 10 to 13 degrees.
Tonight should see clear spells and scattered heavy showers.
Any clear spells will be cold, however, with lowest temperatures of between one and five degrees.
Monday will see a rainy start too, but also mixed with some bright spells.
It will be breezy with moderate to fresh northwest winds and highest temperatures of 11 to 14 degrees.
The rain showers will gradually clear on Monday night and most places will be dry for the evening, except for coastal parts of the north and west. Lowest temperatures are expected to be between five and seven degrees.
Next week will see a cool start turning milder, but staying changeable overall, Met Eireann said.
Here's the outlook, according to its forecasters:
"Most areas will see a good deal of dry and bright weather on Tuesday, although a few showers will develop also especially over Ulster. However, it will be a much cloudier day in the far southwest with outbreaks of rain at times, clearing later in the day. Highest temperatures of 12 to 15 degrees. Moderate northwest winds in most places, but the winds light variable in southwestern coastal parts.
"Tuesday night will be mostly dry with clear spells. Lowest temperatures of 3 to 6 degrees with some mist and fog patches developing in light northwesterly breezes.
"Wednesday will be mainly dry with sunny spells in light northwest or variable breezes. It will be warmer with highest temperatures of 13 to 17 degrees.
"Thursday will be dry with sunny spells in the north and east but it will be cloudier elsewhere with outbreaks of rain likely. Highest temperatures will range 13 to 17 degrees in light to moderate southeasterly breezes. The rain will spread to remaining areas on Thursday night followed by brighter showery conditions on Friday."
