A 1,000 mile-wide 'Norwegian Barrage' could make its way towards Ireland as a result of 'La Nina' according to a weather expert.
Temperatures in parts of the UK could plunge to as low as -10C in the coming weeks with the possibility of an "early winter" with frost and snow expected.
And that change is said to be due to 'La Nina' which Met Eireann spoke about at the start of October when it affected Ireland's weather pattern.
La Nina occurs once every couple of years, disrupting normal weather patterns and causing havoc for conditions around the world.
The event affected Ireland as the north Atlantic jet stream intensified bringing "cool and unsettled conditions" with it.
Weather Outlook forecaster Brian Gaze said: “It looks like an early winter could come because of the Norwegian Barrage, with the cards stacked in favour of a cold second half of autumn due to La Nina.
But Met Eireann has not mentioned this weather phenomenon in their latest long-range update.
Here's the forecast according to them:
Thursday: "Showers this morning as mist patches clear. Good sunny spells will develop during the afternoon though isolated showers will occur. Highest temperatures of 11 to 13 degrees in light easterly breezes."
Tonight: "Well scattered showers will move in from the Irish Sea during the night with clear spells at times. Lowest temperatures of 5 to 7 degrees in light easterly breezes with some mist patches forming."
Friday: "Tomorrow will be a mix of cloud, sunny spells and well scattered showers, though the showers will become more isolated later in the day. Highest temperatures of 11 or 12 degrees in light easterly breezes."
Saturday: "Largely dry with sunny spells as outbreaks of rain clear from the southwest during the morning. Some well scattered showers will affect the country during the morning and afternoon but dying out towards evening. Highest temperatures of 11 to 14 degrees in light easterly or variable breezes but remaining breezier in the southwest."
Sunday: "Dry to start with some bright spells. Cloud will thicken from the southwest later ahead of rain approaching towards evening and extending across most of the country during the night. Highest temperatures of 11 to 15 degrees, coolest over Ulster, in light southerly breezes and dropping to 6 to 10 degrees overnight as southerly winds freshen, becoming strong on Atlantic coasts."
Monday: "A wet day as persistent rain continues to push in from the Atlantic, turning heavy at times as it extends across the country. Highest temperatures of 11 to 14 degrees in moderate to fresh southerly winds, strong on coasts but becoming mainly light variable during the evening."
