Met Eireann gives update on chance of snow for March as maps forecast Arctic plunge

Met Eireann has given an update on whether or not we can expect snow in March, after ‘Beast from the East’ rumours have been swirling in recent weeks.

There has been keen interest in the much-anticipated sudden stratospheric warming (SSW) event, which is now underway. The weather event can lead to cold, dry weather coming into the north of Europe and across Ireland, but exactly how it will impact Ireland’s weather is currently unclear.

In 2018, an SSW event resulted in the entire country being covered in snow. At the moment, some long-range weather maps, which are subject to change this far out, show Ireland blanketed in snow in early March.

WXCharts pinpoints Sunday, March 5 as the exact day heavy snow could start falling, showing more wintry showers right through until Friday, March 10. The weather chart also says there is a 35% possibility of falling snow on Wednesday, March 8 and Thursday, March 9.

However, Met Eireann has dismissed any upcoming ‘Beast from the East’ repeat - although it did note “uncertainty” due to the ongoing SSW. In an update on Friday, the national forecaster said: “A Sudden Stratospheric Warming (SSW) is on-going, which adds a high degree of uncertainty to the overall forecast. Given that caveat, the overall signal from the seasonal models for Ireland during spring (March, April, May), is for slightly above average temperatures with average rainfall.

“March, and possibly the beginning of April, are likely to be cooler and drier than average, with a transition to warmer and wetter conditions for May.” According to Met Eireann, in the near future Ireland can expect overall settled conditions as high pressure dominates and the national forecaster has not forecast any snow for Ireland in March.

Met Eireann’s forecast for the week of February 27 to March 5 reads: “A very settled week with high pressure dominant, mainly centred to the north of Ireland. As a result, Ireland will lie in an easterly airflow this week. Rainfall levels will be well below normal across the country for the time of year, and there will be no strong winds. Mean air temperatures will be average or slightly below average. No warnings or hazardous weather expected.”

Looking ahead to the week of March 6 to March 12, Met Eireann continued: “In Week 2, high pressure is signalled to move away well to the northwest of Ireland with low pressure having more of an influence on our weather. Airflow is signalled to mainly be northerly or easterly.

"There will be more rainfall than the previous week, mainly affecting the north and east. Whilst it will be less settled, it is not looking like it will be very unsettled. Western and southwestern fringes will likely continue drier than normal. Temperatures will likely be average for the time of year. No signs of any hazardous weather at this stage," they added.

For St Patrick’s week, from March 13 to March 19, it said: “For Week 3, there remains a weak signal for the weather to be changeable with highest rainfall amounts for the east or south. There is a signal for it to continue drier than normal in the west. Temperatures signalled to be around average.”

It’s monthly forecast concludes with the week of March 20 to March 25, which reads: “For Week 4, indications show that high pressure will build to the north of Ireland, with low pressure trending to the south. An easterly airflow is signalled for Ireland with average temperatures for time of year or slightly below. Below normal rainfall is signalled for the western half of the country.”
