Weather warnings issued ahead of freezing overnight conditions

Temperatures could fall to as low as minus 5 degrees on Thursday night, Met Éireann has warned. The national forecaster issued a status orange weather warning for Co Mayo and Co Donegal due to the freezing temperatures. The warning will be in effect until 10am on Friday.

A status orange warning was also issued for Connacht, as well as Cavan, Monaghan and Donegal, in relation to “widespread dense fog” which is expected overnight in much of Connacht and Ulster, with some freezing fog in places. This warning will be in place until 11am on Friday.

A status yellow weather warning was issued until 10am on Friday for low temperatures in “much of Connacht, Ulster and midland counties of Leinster and Munster”. Temperatures overnight will fall to minus 3 or minus 4 degrees in places.

On Friday morning, it will be cold with widespread frost and fog, which will be slow to lift in parts of Ulster and Connacht and could well persist in some spots through the day. Sunshine is expected to develop elsewhere. The highest temperatures will range from 3 to 6 degrees, but will remain close to zero where fog lingers. Areas close to the southern and eastern coasts could enjoy temperatures of 7 to 9 degrees.
