The weather event which is forecast to occur over the next week is seen as 'one of the most extreme of atmospheric phenomena'
"Global weather models can usually forecast, quite accurately, what is going to happen in the polar stratosphere one to two weeks in advance, so the upcoming event is highly likely. "It's not yet clear why some stratospheric warming events take weeks to impact the surface while others are felt days later, but it may be related to how the polar vortex changes around the onset of a warming event. "Where the jet stream crosses the Atlantic, it usually points towards Ireland and Britain, but sudden stratospheric warming can lead it to shift towards the equator. Please review their details and accept them to load the content. The average wind direction around the pole may also reverse, in which case a "sudden stratospheric warming" event has occurred. We are likely to be hearing a lot about a weather phenomenon called a 'sudden stratospheric warming' event that is forecast to take place over the next week.
Forecasters have said there is a major Sudden Stratospheric Warming (SSW) event forecast to occur over the next week. An SSW is a weather phenomenon where the ...
“Therefore, for now, it is unresolved how the upcoming SSW event will affect the weather patterns over north-western Europe. “Every SSW event is different and not all of them disrupt the tropospheric patterns below. Major SSW events increase the likelihood for colder than average weather over northern and north-western Europe for several weeks to a few months after the event, but do not guarantee it.
Irish weather experts and forecasters have been put on high alert for the possibility of snow in the next few weeks, thanks to models showing an increased ...
Mr Moore added: "Therefore, for now, it is unresolved how the upcoming SSW event will affect the weather patterns over north-western Europe. "Forecasting how a SSW event imprints on the tropospheric weather patterns below is much more difficult to resolve, especially prior to the SSW event itself." The UK's Met Office has said there is now "an over 80% chance of a major SSW occurring" across the UK and Ireland in the next few weeks.
A Sudden Stratospheric Warming (SSW) event is now 'likely' to take place, which could trigger an extreme bout of snowfall, similar to the 'Beast from the ...
However, this is not always the case and impacts on UK weather can also be benign when an SSW occurs.” They said: “The latest forecasts are showing that a major SSW is now likely to take place. A major SSW often makes the jet stream meander more, which can lead to a large area of blocking high pressure over northern Europe, including the UK [and Ireland]. Conditions will be overall quite dry, with any periods of precipitation resulting in small amounts. That is wait and see.” Models do show increased chance of blocked and possibly cooler weather around start of March. In 2018, an SSW event created an Artic deluge that left Ireland covered in deep snow for several days, with schools cancelled for many counties. It can have very little impact on our weather, it’s wait and see. Its forecast for February 6 to 12 reads: “There is moderate confidence for high pressure to dominate our weather for week 1. "The recent minor SSW weakened the SPV and it’s now likely to collapse and reverse in the middle of February. So an SSW will happen we know that now but what we don’t know is the impact on our weather. [Carlow ](https://www.dublinlive.ie/all-about/carlow)Weather social media accounts, he wrote: “Latest weather models showing risk of SSW increasing but remember any impacts on our weather are uncertain and if it does impact our weather it would likely be towards the end of this month or early into March.”
Latest weather forecasts show that a 'major' Sudden Stratospheric Warming (SSW) event is now 'likely' to take place.

Met Éireann has raised an early alert for a weather system similar to the Beast from the East and Storm Emma events in 2018 that brought Ireland to a sta...
Temperatures are predicted to be close to the seasonal average. It is still predicted to be drier than normal but with much less of a signal than the previous week. The second week from Monday to Sunday, February 20 to 26 show more unsettled conditions over Europe but with a large area of high pressure becoming established in the Atlantic. "For now, it is unresolved how the upcoming event will affect the weather patterns over north-western Europe.

Wetter conditions are then likely to develop across the country on Wednesday.” They said: “The latest forecasts are showing that a major SSW is now likely to take place. “A major SSW often makes the jet stream meander more, which can lead to a large area of blocking high pressure over northern Europe, including the UK [and Ireland]. He said: “There is now over 80% chance of a major SSW occurring. Models do show increased chance of blocked and possibly cooler weather around start of March. That is wait and see.” This blocking high pressure can lead to cold, dry weather in the north of Europe, including the UK [and Ireland], with mild, wet and windy conditions more likely for southern areas of the continent. It can have very little impact on our weather, it’s wait and see. He said: "Every sudden stratospheric warming is different and not all of them disrupt the tropospheric patterns below. This will lead to considerably drier than normal weather, particularly for the west and south of the country. Temperatures will be closer to normal this week, though slightly milder than normal over Ulster and Connacht. For the week of February 20 to 26, it says: “The charts predict that it will turn a bit more unsettled over Europe but with a large area of high pressure becoming established in the Atlantic.
The Sudden Stratospheric Warming event has the propensity to displaces frigid air masses into Europe, bringing with it blankets of snow, but there is no ...
That is wait and see.” The SSW is just one of many factors that will impact the trajectory of our weather through the springtime, so while there is no need to get the gloves and grit out just yet, that may change in the coming weeks. [Met Eireann](https://www.rsvplive.ie/all-about/met-eireann) say that there is "a good deal of uncertainty in the forecast for early next week but current indications suggest that it will turn more unsettled." So an SSW will happen we know that now but what we don’t know is the impact on our weather. In recent days, reports have emerged that Ireland might be in with a chance of frost and snow in the coming weeks in the for of a second "Beast from the East" type of event. This is the same type of event that brought on the heavy blanket of snow that covered much of the country in February of 2018.
Lightning does strike twice as 'Sudden Stratospheric Warming' phenomenon looming.
Light south to southeast breezes with lowest temperatures of 4 to 7 degrees Celsius. The day will start off cloudy with some brighter spells developing by midday. Saturday will be dry in most areas with some isolated spots of light rain or drizzle possible. Until then, Met Éireann's forecast for Saturday 11 February over Co.
