Temperatures to plummet after 18C highs and Ireland's hottest day of 2022 so far

Met Éireann have predicted highs of between 13 to 18 degrees in some counties, feeling hottest in the west and cooler along the east coast.

There may be an isolated shower or two in the west and northwest due to some cloud forming in the afternoon, the national forecaster added.

Sunday night will be largely dry with clear spells, as any showers in the west and northwest die out.

Light and variable winds will cause patches of mist and fog to develop and temperatures will drop dramatically with the possibility of freezing conditions, but the night will generally see lows of one to five degrees.

The majority of mist and fog patches will clear by Monday morning, with some lingering along eastern coasts.

Most areas will stay dry with sunny spells, however there will also be isolated heavy showers in the evening.

Temperatures will range between 13 and 17 degrees with light winds that feel cooler along the east and southern coasts.

Tuesday is forecast to be another sunny day but scattered showers and cloud are predicted to develop in the afternoon, with highs of ten to 15 degrees.

By Tuesday night, the cloud and showers will increase, along with patches of mist and fog as lowest temperatures reach two to five degrees.

Weather conditions are set to turn by Wednesday as a blanket of rain and cloud envelops the country, with more persistent rain moving southwards over the northern half of the country during the afternoon and evening.

This, along with light to moderate winds, will introduce colder air into northern areas, with mid-afternoon temperatures dropping to four to seven degrees in Ulster, but milder temperatures of nine to 12 degrees elsewhere.

And on Thursday, Met Éireann predicts that temperatures will plummet, feeling colder than previous days with afternoon temperatures of just four to eight degrees, although there will be some sunny spells throughout the day.
