Very cold and windy tonight, with a mix of clear spells and scattered showers, the showers turning increasingly to hail, sleet and snow in Ulster, Connacht and in north Leinster, with some accumulations by morning.

More persistent rain and sleet will move in across much of Munster later in the night, with some snow, mainly over high ground.

Minimum temperatures minus 1 to plus 2 Celsius, in fresh westerly winds, strong along north and northwest coasts.

Tomorrow, Thursday, will be bitterly cold, with scattered showers, many falling as hail, sleet and snow, some of them heavy and thundery, especialy in the west and north.

Some sunny spells also, especially in eastern and southeastern coastal areas, where the showers will be more scattered.

In Munster and parts of south Leinster, it will be cloudy in the morning, with more persistent rain and sleet for a time, but there is also a risk of snow…
