Temperatures are expected to drop sharply after dark this evening, with widespread frost and some icy patches forming under mostly clear skies.
However, frost will clear from parts of west Connacht and west Ulster later in the night as increasing cloud brings a few patches of drizzle there.
Minimum temperatures ranging from -3 to +1 degrees in light variable breezes, leading to some fog patches developing in the southern half of the country.
