Arctic Blast: Snow, Ice, Hail Threaten UK & Ireland

Northern Ireland is under a snow and ice warning until noon, with arctic air causing strong northerly winds. Commuters travelling over higher elevations are cautioned about potential disruptions due to 1-3cm of snow, potentially reaching 5cm in some spots, alongside risks of hail and lightning.

Overnight temperatures will drop to freezing and below, leading to ice formation on untreated surfaces. Daytimes will be significantly colder than average for this time of year, with highs expected between 3-6°C, feeling closer to freezing due to wind chill. Sub-zero temperatures are also forecast for Wednesday and Thursday nights.

Similar warnings are in place for five counties in the Republic of Ireland, anticipating hail, sleet, and snow accumulations, especially on higher ground. Temperatures across both the UK and Ireland are expected to gradually rise closer to seasonal averages by the weekend.
