The weekend will see largely mixed conditions with cloud and rain. However, it will turn drier and warmer next week, according to Met Éireann.
It will be cloudy, murky and wet today (Friday, August 20), with outbreaks of rain becoming widespread through the morning hours. Rain will be heavy and possibly thundery in places, especially in western parts, with a risk of localised flooding.
Highest temperatures will be 17° to 20° in mostly moderate southerly winds, fresh on northern, eastern and southern coasts. The rain will start to clear from the west and southwest later in the afternoon, where it will brighten up with lighter winds. However, it will remain breezy with rain elsewhere.
It will become dry in many places for a time tonight with quite widespread misty conditions and some fog setting in. However, a spell of heavy rain will move into the southeast overnight, with heavy showers developing in the southwest and west towards morning.
It will be a mild and humid night with temperatures remaining above 14° in parts of the east, a little cooler in the west with lows of 11° to 14°. Winds will be mostly light and variable in direction.
It will be another mixed and dull day tomorrow (Saturday, August 21) to begin, with rain lingering in eastern counties through the morning. Heavy showers and sunny spells in the west and southwest will spread eastwards through the day, with heavy or thundery showers breaking out in the east and north from late afternoon.
Localised downpours will bring a risk of spot flooding. Highest temperatures tomorrow will be 17° to 20°. Light southerly winds will become westerly later in the day.
Showers will continue for a time on Saturday night but will die out early in the night, becoming dry in many areas. It will be rather cloudy, with some mist or fog developing overnight. Lowest temperatures will be 11° to 14° with a light westerly breeze.
Any mist or fog will quickly clear on Sunday morning (August 22). Scattered showers will develop but they will be much lighter compared to Saturday, with a good deal of dry weather throughout the day.
