National Forecast

22 August 2017 11:34


Widespread showers, with heavy thundery downpours through the course of the afternoon and evening, particularly over parts of Leinster, Connacht and Ulster with the risk of localised spot flooding. Misty too with hill and coastal fog. Top temperatures of 18 to 22 degrees. Light to moderate southeast winds will veer southwest later.


Heavy rain with thundery bursts will continue for a time across parts of Ulster early tonight but will clear away to the northeast soon after midnight. Cooler, clearer weather will follow with a few showers along Atlantic coasts. Minimum temperatures of 11 to 13 degrees. A few mist patches will form under light southwest breezes


Largely dry at first on Wednesday morning along the eastern half of the country with some sunny spells, however further west there will be a few showers. The showers will become more widespread through the course of the afternoon. Top temperatures of 16 to 20 degrees with moderate to fresh southwest winds.


HEADLINE: Some rain or showers at times (mainly affecting northwestern areas) but overall a good deal of dry weather and with temperatures close to the seasonal norm.

WEDNESDAY NIGHT: It will be dry across the bulk of the country on Wednesday night with clear spells and just a few mist or fog patches. However, showers or longer spells of rain will edge into north Connacht and Donegal at times. Minimum temperatures of 9 to 12 degrees in moderate southwest winds which will increase strong at times in the northwest.

THURSDAY: Low pressure is expected to be anchored just off the northwest coast on Thursday and this will feed in showers or longer spells of rain to parts of Connacht and Ulster. However, elsewhere it is expected to be a mainly dry day with a mix of cloud and sunny spells. Maximum temperatures of 15 to 19 degrees in fresh to strong and gusty southwest winds.

FRIDAY: An area of low pressure to the north of Ireland will fill and dissipate during the course of Friday. There will be showery rain across northern areas to start but the rain will fragment and ease during the course of the day. Predominantly dry elsewhere with sunny spells and just a few isolated showers. Highest temperatures of 17 to 20 degrees in light, variable breezes.

SATURDAY: Current indications suggest that Saturday will be a largely dry day with a mix of cloud and bright/sunny spells. A few showers are likely to develop in the afternoon but they will be generally light in nature and well-scattered. Maximum temperatures of 18 to 21 degrees in light, variable winds.

SUNDAY: Still some uncertainty with regards to weather conditions on Sunday. However, the latest guidance indicates it will remain largely dry with some sunny spells and with temperatures reaching the low twenties.
