Keeping it cool: Bank holiday fine and dry, but not too warm
It could be a case of blink and you'll miss it as the fine weather will return for the bank holiday weekend - just don't forget your coat.
While the weather will be largely warm, there won't be any May temperature records broken any time soon.
Temperatures will be slightly below normal for early May, with highs of 12C or 13C, pushing a little higher again on bank holiday Monday. There will also be frosts by night.
However, high pressure will dominate over the coming days, bringing dry and calm conditions.
A Met Éireann forecaster told the Irish Independent: "High pressure normally means fine weather, but doesn't mean wall-to-wall sunshine.
"There could be good sunshine though, especially on Saturday, and light winds.
"But it won't feel overly warm, and temperatures will be trending below the usual May weather.
"Saturday looks like a sunny day, with variable rain. It's dry and settled with light winds - definitely good weather for walking and gardening, but with regards to bathing and sunbathing, it's probably a bit cool for that just yet."
Temperatures will be coolest across the north and east, with widespread frosts as temperatures drop back close to freezing by night.
Today will be warm, with temperatures peaking at 15C with moderate breezes. However, this will fall back to just 3C or 4C tonight.
Tomorrow will be mainly dry, with a mixture of cloud and sunny spells, and temperatures ranging from 9C in the north to 13C in the south.
There will be a slight risk of showers along the Irish Sea coast.
Meanwhile, for hay fever sufferers, there will be a mild pollen count today and tomorrow.
