Temperatures to plummet to as low as -4 degrees tonight as Bank Holiday chill takes hold

Temperatures are set to plummet to as low as -4 degrees in some areas tonight as the bitterly cold weekend continues to grip.

It will be mainly dry and bright today, with sunshine and just a few isolated showers in the southeast early on. Frost and any fog will clear gradually this morning, though a few pockets of fog may linger in the midlands until early afternoon. Quite cold, with highest temperatures of 7-10 degrees, in light north to northeast or variable breezes.

Tonight will be dry in most areas, with clear intervals, but cloud will increase from the Atlantic, bringing a little patchy light rain or drizzle to the west Connacht coast towards morning. Becoming breezy along Atlantic coasts, with freshening south to southeast winds, but winds elsewhere will remain light. Very cold away from Atlantic coasts, with frost and a risk of a few icy patches. Patches of mist and fog also. Minimum temperatures -4 to +2 degrees.
