Following record-breaking temperatures earlier this week that saw highs of 33 degrees Celsius, a band of low pressure will move across the country, bringing with it showers and cloudy conditions.
But the forecaster has said that from next week we should see temperatures creep back up as the sun reappears.
In the meantime, while it will be mainly dry this morning, there will be a few light showers in the north and west and it will be cloudy too, with limited sunny spells.
Later in the afternoon, a few showers will move into the southwest and temperatures will rise to between 15 and 19 degrees in mostly light northerly or variable breezes.
It will be a dry start to Friday with warm, sunny spells developing. There will be just a few light passing showers across the south and west of the country, with cloud increasing into the evening.
