It will be dry with clear spells in many areas, however, scattered wintry showers of hail, sleet or snow will continue to affect eastern and southeastern counties. Lowest temperatures of -1 to -5 degrees, coldest in Connacht and Ulster where temperatures may fall even lower locally. Some freezing fog patches may form in the light northerly or variable breezes."
Frost, ice and freezing fog patches will linger in parts throughout the day tomorrow, with sleet and snow showers in parts of the country.

The snow and sleet forecast comes after Met Éireann forecast several days of scattered snow showers this week, along with a ‘Sudden Stratospheric Warming’ (SSW) for early January.
The weather event described as a SSW led to the 2018 snow storm known as the Beast from the East.
However, the forecaster has said it is currently uncertain how January's SSW will affect Ireland’s weather in the coming weeks, because it is already in a “very blocked” pressure set-up.
