Met Eireann forecasts unsettled conditions as mercury nosedives due to 'polar airmass'

Ireland will shiver as temperatures are set to nosedive due to a "polar maritime airmass".

After a record-breaking summer, temperatures are set to dip and unsettled weather will take hold. Speaking about the week starting from September 26, a Met Eireann forecaster said: "With low pressure nearby Ireland for week 1, repeated bands of rain and showers will fall over the country throughout the week.

"A predominantly northwesterly airflow will lead to a mostly polar maritime airmass affecting the country, bringing close to average or slightly below temperatures for the time of year."
