Met Eireann has issued a weather advisory for the next seven days:
“Very cold this week as an Arctic airmass sets in, bringing sharp to severe frosts and icy stretches on roads. Showers of hail, sleet, and snow will occur during the second half of the week. Updates with potential warnings will be issued in the coming days.”
Overview: Turning much colder, especially from mid-week onwards, as the winds become northerly. Plenty of dry weather is expected, though there are likely to be wintry showers at times, especially in northern and northwestern parts. Frosty conditions will develop by night.
Monday night will see some scattered showers continuing near the east and south coast but it will be mostly dry elsewhere with clear spells. Lowest temperatures of -2 to 3 degrees, coldest in the north with a widespread frost setting in, in light or moderate northeasterly breezes.
Tuesday will be dry in most areas with good sunny spells in many areas. Just a few isolated showers especially near the east coast where it may be somewhat cloudier. Highest temperatures of 4 to 7 degrees in light north to northeast breezes.
Very cold on Tuesday night with light northerly breezes and largely clear skies. Isolated showers may continue near the north and northwest coast. Widespread frost is expected as temperatures fall to between 0 and minus 4 degrees.
Good sunny spells on Wednesday, though it will remain chilly with afternoon temperatures reaching just 2 to 6 degrees. Dry for most areas. However, scattered showers will affect northern and northwestern coastal areas and these will edge further inland over Ulster and Connacht during the evening and night, turning increasingly wintry with falls of snow likely, especially on higher ground. Light north to northwesterly breezes. Bitterly cold overnight with temperatures below freezing countrywide leading to a widespread sharp to severe frost and icy stretches.
Thursday looks like a very cold day countrywide with sunny spells and scattered wintry showers of hail, sleet and snow in places. Temperatures in the low single figures in a light northerly breeze.
Current indications are that it will stay very cold through the remainder of the week and for next weekend too.
