Met Éireann's latest weather forecast will see a big jump in temperatures but the heat is set to bring thunderstorms, possible flooding and high humidity.

In her weather bulletin after the RTÉ news, Met Éireann meteorologist Michelle Dillon outlined what to expect. 

"It will be increasingly hot and humid next week with plenty of thundery downpours," she said.

She said Sunday will mark the start of the weather change driven by hot weather over Europe.

"It is really on Sunday morning when we will see heavy rain move in from the south and the southeast. That rain will become increasingly widespread and heavy as we go through the day. Some heavy thundery downpours with the risk of spot flooding," she said. MORE BELOW PICTURE.placeholder image

The temperatures will begin to climb further on Monday bringing humid conditions.

"That high humidity sparking thunderstorms. Then on Tuesday, hotter again with temperatures up to 23 or 24 degrees especially across the northern half of the country but we will see an area of thundery rain pushing up from the south as we go through the day," she said.

NATIONAL OUTLOOK

OUTLOOK: Becoming very warm and increasingly humid well into next week with temperatures widely rising into the 20s. Some thundery rain is possible too though with low pressure lining up close to the Bay of Biscay.

SATURDAY NIGHT: Scattered outbreaks of rain will move from the southwest overnight. Misty with hill and coastal fog too. Mild and humid with overnight lows of 10 to 13 degrees Celsius, in mostly moderate southeast breezes.

SUNDAY: A locally damp start with heavy rain also affecting southern counties. Heavy thundery rain in the south will slowly push northwards through the day with high accumulations possible in some relatively short durations. Spot flooding is likely. North Ulster may, however, hold dry and bright until later in the afternoon. Feeling humid, with highs of 15 to 20 degrees Celsius (south to north), all in a moderate easterly breeze.

Further widespread rain or showers for Sunday night, with a chance of a few thunderstorms. 

NEXT WEEK: Latest indications are for very warm and humid weather, with temperatures several degrees above normal, generally into the low 20s, and even a little higher on some of the days later in the week. Whilst there will be lengthy spells of summer sunshine, some heavy thundery showers will break out from time to time too. Easterly breezes will be replaced by more southerly ones later in the week.
