Met Eireann has forecast that "heavy and thundery" showers are set to continue throughout the weekend, with Dublin to be as hot as Lanzarote as temperatures soar to mid-twenties.
There will also be spells of sunshine and temperatures as high as 26 degrees. Today will be mostly dry in the capital with a chance of heavy showers.
It's set to be warm and humid with highest temperatures of 21 or 22 degrees in moderate south to southwest winds. Tonight it will stay cloudy and humid with isolated patches of light rain and drizzle, with mild temperatures from 17 to 18 degrees.
The good weather that we've seen earlier in the week seems set to take a U-turn with heavy rain set to dominate the weekend. Met Eireann has also ruled out heatwave-like conditions, stating that “it will stay unsettled for the weekend and into next week with outbreaks of rain or showers, potentially turning heavy at times”.
