According to the forecaster:
"Most of the country will be dry at first on Saturday night but heavy rain or showers will move up over the country overnight, with particularly heavy falls possible in the east and southeast in the second half of the night.
"Lowest temperatures will be between 9 and 13 degrees from north to south and winds will be mainly light to moderate from a variable direction, becoming northwesterly by morning."
As for Sunday, further rain is expected but then will be cleared away, becoming generally drier. Sunshine and scattered showers are also expected throughout the day, with most frequent showers occurring in the northwest of the country.
Highest temperatures of 19 to 21 degrees are forecast, with moderate west to southwest winds.
