National Outlook
Overview: Changeable conditions through the rest of this week. More generally settled weather developing later this weekend.
Wednesday Night: Turning drier for many on Wednesday night as showers become confined to the west with plenty of clear spells developing. Lowest temperatures of 8 to 11 degrees in mostly light southerly breezes.
Thursday: Mostly dry and bright to begin with sunny spells and just well scattered showers, mainly in the west. Cloud will thicken from the Atlantic as the day goes on, and a spell of more persistent rain will follow later in the day. Some heavy bursts are possible. Highest temperatures of 14 to 17 degrees in moderate, occasionally fresh, south to southwest winds. Current indications suggest mostly cloudy conditions with showery outbreaks of rain pushing eastwards over the country, becoming confined to western parts towards morning. Lowest temperatures of 9 to 13 degrees. Mostly moderate south to southwest winds will ease light to moderate later in the night.
Friday: Uncertainty in the details persists into Friday; but at present a mix of bright spells and scattered showers seems like the most probable scenario. Highest temperatures of 14 to 18 degrees with light to moderate south to southwest breezes.
This Weekend: Still the chance of some rain at times on Saturday but a gradual trend towards drier and more settled conditions is signalled into Sunday as high pressure builds nearby. Maximum temperatures will be in the mid to high teens.
