Temperatures to drop after mercury hits 14C
Temperatures swept into the mid-teens over the weekend as a plume of southerly warm air made dreams of a white Christmas a distant memory.
Yesterday was one of the warmest December days in recent years as parts of the country saw highs of 14C.
However, the mild weather is due to take a dip in the coming days and the temperatures will drop notably throughout today.
"As a rough guide, 8C to 9C is the average temperatures for this time of year and we're above that," said Met Éireann meteorologist Andrew Doran Sherlock.

"Generally, we have westerly flows of wind and we're currently experiencing a southerly flow, which has created a warm air mass over the last few days."
A cold air mass will move over the country in the coming days but temperatures will be warmer in the south of the country, with highs of up to 6C.
Party-goers can leave their brollies at home for new year's celebrations as tomorrow will be mostly dry, with temperatures reaching 10C, with some drizzle across coastal areas.
New Year's Day will be mostly the same and the night will be frost free.
According to Mr Sherlock, the reasons for the high temperatures are difficult to determine.
"It's hard to say what the cause is and climate attribution is a growing science," he said.
"We are experiencing comparatively mild weather and this is due to a southerly flow of wind."
