Potential for another wave of extreme winds Sunday Night/Monday

Higher res models are now showing the potential for severe weather as a wave develops and a small but tightly wound circulation crosses the country late Sunday. The exact scale and the development of the disturbance is at this point somewhat uncertain.

The NAE picks up the feature as potential extreme wind event for some.

2 in a row!

I think we should concentrate more on wind and rain events rather than snow. They're more common and always guaaranteed.
But I'm still a snow lover.

Sunday nights feature needs close watching.
Could go either way, but were it to upgrade from where it's at it could well raise eyebrows

An interesting feature on the NAE alright.

Storm force winds along some west/southwest coasts here.




And then later sustained winds close to gale force in some inland areas as it crosses the country.



Worth keeping an eye on for sure. Since its a small system you could easily see some changes in track and intensity in this short time which could have a big impact on which areas might see strong winds & how strong they would be, since it's a narrow windfield.

We'll see how much changes on the 12Z.

Met Eireann highlight the uncertainty:

Very wet and windy overnight Sunday night with strong and gusty southerly winds and with heavy rain in many places. Lowest temperatures 6 to 9 C. Some severe gusts are possible in places, but this is not certain as of yet.

There will be strong winds this evening especially in the northwest regardless of the development of the system late Sunday.

What about this from IWO for tomorrow morning, nothing on met.ie about it.
WEATHER UPDATE: We are expecting further strong winds overnight (peaking 0400-0800h Sunday) mainly across northern counties. The peak gust potential is similar to Friday's max recorded gusts of 120-130 km/hr. After somewhat of a midday easing to 50-70 km/hr, another interval of about 80-110 km/hr winds are likely during Sunday evening. The winds will be strongest in southern and eastern counties.

I have to disagree with this. I don't think it will be that severe at all this evening/tomorrow. The severe winds will be too far to the northwest, out at sea. Strong winds, but the models don't show potential for 130 km/h gusts. Maybe up to 100 km/h on exposed coasts. Inland, just looks windy.



This is different the system being shown for Sunday night / Monday morning, in case anyone is confused.
