Donald Trump style u-turn in Irish weather forecast

Met Éireann is forecasting the fine spring weather to come to a shuddering halt with everything from hail, thunder and frost on the way.

After weeks of blue skies and no rain, Met Éireann has put people on alert for a big weather change over the weekend with Sunday marking the start of an unsettled spell.

Met Éireann says scattered showers will spread eastwards to Laois and other parts of the country on Sunday morning with sunny spells in between.

The forecaster says some of the showers could turn heavy with hail and the chance of the odd rumble of thunder. Met Éireann also expects it to be a noticeably cooler day with highest temperatures of just 9 to 12 degrees in mostly moderate southwest to west winds, increasing fresh at times along Atlantic coasts.

While showers will become isolated on Sunday night and largely confined to western and southern coasts clear spells will develop causing temperatures to plunge to zero with a touch of grass frost possible.

While Monday will start dry scattered showers will become fairly widespread by the afternoon. Met Éireann says some could be heavy and of hail with a chance of isolated thunderstorms. 

In its further outlook Met Éireann says the indications suggest that the weather will remain fairly cool and unsettled with further showers or longer spells of rain on the way.

Met Éireann's farming section says rainfall could be 140 % above average in the week ahead with sunshine amounts just average or above average.

National Met Éireann Forecast issued on April 10.

Friday, April 11: Any mist and fog will soon clear for most on Friday morning to leave another dry and mainly sunny day. Fog could linger in some coastal areas though, particularly in the west and south, so it'll be cooler and duller if and where that fog persists. Highest temperatures of 16 to 21 degrees, generally, in light southwesterly or variable breezes.

Dry and clear on Friday night with areas of mist and fog forming overnight, becoming dense in parts. Lowest temperatures of 1 to 6 degrees in light southerly or variable winds.

Saturday: Saturday will be a cloudier day overall, though hazy sunny spells will still occur. Mist and fog patches will gradually clear through the morning and many areas will be dry, but a few patches of light rain and drizzle will develop later in the afternoon and evening. Highest temperatures of 12 to 16 degrees with light southerly or variable breezes, gradually veering light to moderate westerly. Any rain and drizzle will die away on Saturday night leaving variable cloud and clear spells. Scattered showers will spread from the Atlantic overnight, affecting mainly western counties. Lowest temperatures of 3 to 7 degrees.

Sunday: Scattered showers in the west will spread eastwards over the country on Sunday morning with sunny spells in between. Some of the showers could turn heavy with hail and the chance of the odd rumble of thunder. It'll be a noticeably cooler day with highest temperatures of just 9 to 12 degrees in mostly moderate southwest to west winds, increasing fresh at times along Atlantic coasts. Showers will become isolated on Sunday night and largely confined to western and southern coasts as winds falls light southwest to south. Cloud amounts will vary but clear spells will develop. Lowest temperatures of 0 to 4 degrees with a touch of grass frost possible.

Monday: Monday will start out dry with sunny spells for many but scattered showers near Atlantic coasts will become fairly widespread by the afternoon. Again, some of the showers could be heavy and of hail with a chance of isolated thunderstorms. Highest temperatures 9 to 12 degrees in light to moderate southwest winds, fresh at times along Atlantic coasts.

Further Outlook: Current indications suggest our weather will remain fairly cool and unsettled with further showers or longer spells of rain.
