Met Eireann issues an emergency weather warning in Ireland, and snow is expected as ‘polar front’ -CC hits


Met Eireann has warned that a “significant change” is on the way as “cold polar air weapon” could bring snow to some areas.

A nationwide weather consultant is in place until just before midnight on Saturday as “sharp to severe ice and icy stretches” are expected.

While experts also say snow could fall on lower ground later this week as cold front moves in.

A forecaster explained: “A significant change in our weather pattern will occur this week with a cold polar marine air weapon sweeping across the country. A cold front will extend south-east across Ireland on Tuesday night and will mark the start of an era cooler and more wintery obvious.

“The change in weather is caused by the amplification of the polar jet over the North Atlantic which assists in the development of a blocking high pressure system that will extend from the Azores to Greenland.

“This will allow southward polar air flooding towards Ireland and north-west Europe. However, as this cold air moves over the relatively warm North Atlantic seas, the depth of the cold will be adjusted leading to a winter mix with snow fall confined mainly to high ground., but with some snow to lower levels possible at times later this week. “

Meanwhile today there is a risk of hail in places before a frosty night, expected to only cool as the week progresses as the lows reach -4C on Thursday night.

Cloud will build across the north and east through the night, bringing further widespread winter showers Afternoon temperatures of 4 to 6 degrees with fresh northwest winds bringing an additional wind chill factor.
