Weather warning sees Northern Ireland bracing for freezing temperatures in week ahead
Northern Ireland will be hit by sub-zero weather this week, with the possibility of hail and snow as winter closes in with a vengeance.
After highs of 10C over the weekend, the weather is likely to remain relatively mild until Wednesday evening. However, forecasters predict an Arctic chill will plunge temperatures to a freezing low from Thursday morning.
Met Eireann meteorologist Vincent O'Neill said: "On Wednesday night there's going to be heavy rain, and when it clears there will be a notable change in temperatures.
"A much colder air mass will then take charge from Thursday morning.
"It will be very cold and get progressively colder coming into Friday."
In the north and west, temperatures will plummet to -3C at night, with wintry showers, hail and snow continuing into the weekend, the forecaster said.
