Snow and sharp frosts are forecast for Donegal this week as an Arctic airflow moves through the country.
Sub-zero temperatures will bring widespread sharp frost and ice risks “until at least Thursday”, Met Eireann warns.
The north coast is bracing for the coldest conditions, with wintry showers expected throughout the week ahead.
Tonight will see temperatures dipping again to -1C, before a “very cold” Arctic airflow feeds down.
Monday’s overnight temperatures will plummet to lows of 0 and -4C. Tuesday will see well scattered sleet or snow showers and very low daytime temperatures also, and a “few wintry showers will continue near northern coasts overnight”.
Wednesday will have a very cold start with icy stretches, but with a good deal of dry bright sunshine about too.
Widespread wintry showers and lows of -2 to + 2 degrees are forecast for Wednesday night.
Met Eireann says there is some uncertainty to the details of the midweek forecast, which will be updated in due course.
