HOPES for an imminent resurgence in another warm weather spell like last month have been dashed, according to local and national forecasters.
Met Eireann had indicated that this coming week could signal a return to temperatures above average.
Its forecast for June 15 (tomorrow) to next Sunday stated: “There is a signal for high pressure, which may bring more settled conditions.
“Rainfall amounts will be slightly below average across the country, with longer dry spells likely to develop. Temperatures will rise to above average nationwide.”
It sparked analysis of weather models by popular news channels like the Donegal Weather Channel.
Some regional forecasters tipped the temperatures to reach the high 20s and even reach 30C.

But Donegal Weather Channel founder Kenneth McDonagh’s updated forecast for the coming days said: “Monday looks to be a dry day with temperatures between 18°C and 23°C across the nation.
“Models hint at a warm spell lingering into next week, but the drier weather past Tuesday remains uncertain.
“Currently, Tuesday and Wednesday temperatures could stay in the high teens to low 20s, accompanied by some rain.
“There are indications that this warm spell may give way to some unsettled conditions midweek, but warmer and drier weather may return by next weekend, just in time for the Donegal Rally.”
In its revised forecast, the Irish Weather Channel said for the week ahead: “It still looks temporarily drier before mixed conditions again, but not as warm as the weather systems overall looked.
“This means in simple terms that the warm air that was previously indicated is not getting a direct feed to Ireland so will be reliant on the sunshine. But it will still be warmer than it has been.”
Met Eireann’s forecast for tomorrow states highest temperatures will be 22C.
It revealed: “Monday will be generally dry with a mix of cloud and hazy sunshine.
“However, patchy mist and drizzle will move in later. Rather humid with highest temperatures of 18C to 22C.
“Tuesday will be breezy with scattered outbreaks of rain.”
