Wrap up, as icy spell to grip country in days
WRAP up warm because bitterly cold conditions are set to blast the country for the rest of the week.
The entire country will feel the drop in temperatures and experience wintry showers, although Met Eireann says the most severe weather will hit the north and west.
Several centimetres of snow is expected to fall on higher ground at the tail end of the week, returning parts of the country to the snowy conditions seen two weeks ago.
While we are not going to get anything like the "historic" snowstorms predicted for parts of the US, temperatures could plunge as low as -4C later this week.
Temperatures will reach a high of 9C today, with outbreaks of rain becoming widespread tonight.
But this will give way to a cold and blustery day tomorrow with showers turning wintry in the north and west.
It will become bitterly cold from tomorrow night with temperatures plunging sharply and wintry conditions remaining the norm for the rest of the week.
A strong north-west airflow will take hold, bringing with it Arctic conditions and falls of sleet and snow, particularly in parts of Ulster and Connacht.
The outlook for the weekend is for much of the same - wintry showers with some good spells of sunshine but severe frosts and icy roads by night. A yellow weather warning has been issued for snow in Northern Ireland as the UK Met Office expects up to 10 centimetres to fall on higher ground.
Meanwhile, Aer Lingus has been forced to cancel a number of flights between Dublin and New York due to blizzard conditions and falls of snow of up to 90 centimetres in New York.
The US National Weather Service has described the approaching weather system as "crippling". Parts of the east coast are expected to experience snowfalls of between 30 and 60 centimetres, with the New York area experiencing the worst of the conditions of lashing winds accompanying the snowfalls.
Residents have been advised to remain indoors and keep warm as they are hit by conditions "worse than ever experienced before".
Those travelling to the US are also advised to check with the airlines in advance for an update.
