Ireland weather: With Eireann cold wave warning issued as urgent update on ‘December snowstorm’



Met Eireann has warned that “much colder” conditions are on the way from the middle of next week as a major winter turn is expected.

While Carlow Weather’s Alan O’Reilly has also released an urgent update on a forecast model showing snowfall during a storm in early December.

The weather expert said the ECMWF model for December 5 is “a great outlier” and that sharing the forecast without context is “just silly.”

He explained, “The nighttime run of the ECMWF model shows a storm in 9 days of snow. * But * the ensembles show that this is a great outlier. That’s the main run shown which is well beyond the average of the weather models, the black line on the first picture shows this.




“The average run here, as you can see, is completely different. In other words, ignore all online predictions based solely on this one model run that doesn’t seem to be in line with all the others and even the average on the same model.

“It’s silly to share the model prediction without understanding and sharing it within the context of the ensembles.”

Meanwhile, a frigid night is on the horizon tonight with temperatures dropping to -2C.

A Met Eireann forecaster said: “A cold start with fog and frost in places. It will be a mostly dry, but rather dull day, with remote showers on the coast. Temperatures this afternoon of only 3 to 6 degrees in the north, up to 8 degrees to the south, the wind is slightly southerly or variable in direction.

But next week we’ll start to see a change, with “much colder” weather expected from Wednesday.
