Last of the summer sun with rain on the way
High temperatures are forecast for today but more miserable weather is on the way before children return to school at the end of the month.
Forecasters say wild and wet Atlantic weather systems will make a return to Ireland tomorrow evening.
Today could see temperatures reach 23C in many areas away from the east and south-east coasts, where it will be around 5C cooler due to sea fog in places.
But the brief few days of warm weather will come to an end from tomorrow evening as a low pressure system heralds at least five days of rain, showers and drizzle.
Met Éireann forecaster Gerry Murphy warned people to "make the most" of the weather. "It is going to get cooler and quite unsettled after that," he said.
"After Tuesday there is a fair amount of rain in store with above-average rainfall for most places this week."
Some areas, he said, could see twice the average rainfall over the next week.
"Temperatures could reach 24C on Tuesday and it will very pleasant indeed, but by Tuesday evening we will see a low-pressure system bringing rain to western areas to reach all areas by Wednesday," said Murphy.
"Low pressure will dominate for the rest of the week unfortunately."
On Wednesday, it will be mostly cloudy, with outbreaks of rain which could be heavy and possibly thundery in places. It will be fresher on Wednesday night as the rain is replaced by scattered showers.
Thursday doesn't look any better and it will be quite cool and fresh, with bright spells and scattered showers, possibly longer outbreaks of rain in places, especially in the north and north-east - with temperatures of 16C in the north but up to 20C in the south.
Irish Weather Online forecaster Peter O'Donnell said: "After some breaks on Thursday, another interval of showers or rain late in the week may persist into Saturday. There may be a gradual improvement but the pattern now looks rather variable with further intervals of showers at intervals of 2-3 days with the odd dry day in the mix, and temperatures not far from normal."
