Temperatures could hit 25C in Ireland before the end of this week but there is a weather "risk" in the latest forecaster, according to Cathal Nolan from Ireland's Weather Channel.

In his latest forecast, he says Thursday will be "overcast with a weak weather front slowly decaying over Ireland.

"This will bring with it rather muggy conditions with outbreaks of light rain or drizzle for much of the day, though perhaps clearing up layer. Highs tomorrow of 20 or 21 degrees Celsius.

"Our weather on Friday looks like being rather pleasant for many, with a deep area low pressure to our northwest drawing up some very warm air from the south. Highs on Friday could locally reach 24 maybe even 25 degrees Celsius on the Lee side of mountains, especially across the greater Dublin area. Some hazy sunshine is likely though clouding over later from the west."

It's Friday night that looks like bringing a risk of flooding with heavy rain.

For the weekend, he says: "Early morning rain clearing on Saturday with our weather gradually brightening up from the west through the afternoon with a pleasant evening for many. The opposite is then true on Sunday with dry conditions to begin with by showery outbreaks of rain are likely into the afternoon and evening. Temperatures between 17-19 degrees generally in westerly winds."

Looking beyond that again and towards August, Cathal says "there are some tentative signs that summery conditions may develop into the second week of August as indicated by the increasing red segments of the attached picture. This graph shows the longer term trends in our wether, with the red segment used to identify periods where blocking is most likely."

Meanwhile, Met Éireann's outlook for the remainder of this week says: "Generally unsettled with rain or showers at times. However, there will be dry intervals too."

For Thursday, they predict "a dull, damp and misty start with outbreaks of rain, lingering through the day in the east, but with a clearance to hazy sunny spells gradually building in from the west through the afternoon and evening. Continuing humid until the rain and drizzle clears, with highest temperatures of 16 to 21 degrees with light to moderate southerly or variable breezes with some coastal fog likely for the south."

The forecast beyond that reads: "Dry for most with a mix of cloud and clear spells [on Thursday night] though there will be a few patches of light rain and drizzle about. Temperatures not falling below 10 to 15 degrees generally in light southwesterly or variable breezes with some mist and fog patches developing.

"A mostly cloudy start [on Friday] with scattered outbreaks of rain and drizzle, most frequent for Atlantic coastal areas. Driest in the east and southeast with the best of any sunny spells. Humid with highest temperatures of 17 to 22 degrees generally with moderate southwesterly winds developing, fresher near some coasts.

"Cloudy with outbreaks of rain becoming widespread, turning heavy at times with a chance of spot flooding [on Friday night]. Mild and humid with temperatures not falling below 13 to 15 degrees with mostly light southwesterly or variable winds.

"A wet start with widespread showery outbreaks of rain, heavy in places with a chance of spot flooding [Saturday]. Later in the day, the rain will ease from the southwest. Highest temperatures of 15 to 20 degrees with moderate, occasionally fresh northwesterly winds gradually developing.

"Any lingering rain in the north and east will clear away early on Sunday morning to leave a largely dry day with sunny spells and well scattered showers. Highest temperatures of 15 to 19 degrees."
