On this chart, Munster, most of Connaught and most of Leinster having a fun day.
5 - 10 cms should be expected but more on high ground.
I know this is a silly annoying question, but how does the capital fare in that chart0 -

Comparison of an ICON and EURO4 chart issued just before Storm Brendan on 13-1-20 and today's ICON 18Z and ARPEGE 12Z for this Sunday. ICON did better than ECM for Storm Brendan by far, ECM overestimated the wind speeds by about 10 km/h or so I would reckon and much more in the SE .Brendan's core and strongest winds stayed off the W coast that day keeping the strongest winds along the NW, W and S coasts.
Not as strong looking for the coasts on this run , the biggest difference is the higher and more sustained wind speeds inland combined with the heavy driving rain from this storm.
Accumulations from Fri day evening, Sat and Sunday

I was just about to post the same, is there a small low passing over, looks like a small circulation on the radar. 5 miles south of Tuam.
Hard to know, but looking at the isobar map (based on the GFS 12z) for the present moment, nothing seems untoward, except maybe the sharp wind shift that must be associated with some sort of trough.

I have a funny feeling we will get to see some snow falling at least this time
Also in South Dublin on the side of the Dublin Mountains ......
Took long enough, no Snow here since March 3rd 2019 during that event where the middle of the country was 1-2C and 0C DP
Ninja snow that was!0 -

Was just looking up the charts for convection on Sunday and the power and lights went out here followed by a clap of thunder ( the Omens are good ! )
Looking good for thunderstorms early Sunday morning ( especially in the SW ), tons of shear available, lapse rates ok, some very heavy bursts of rain .

The advancing cold air mass.
Showers turning increasingly wintry Late Sunday early Monday morning, turning more to snow showers during Monday and more so again during Tuesday.
Fairly crude basic maps but ECM did very well predicting the last bit of snow we had. Only a rough guide to where might get some accumulations I reckon.

I'll take 0.1cm0 -

That chart is for wind sheer high up, it is one of the parameters when looking for convection and thunderstorms.
From Meteologix ' This map displays the forecast deep layer wind shear in the 0-4 mile (above ground) layer. This is calculated by taking the wind vector at the surface and subtracting it from the wind vector 4 miles above the surface. The more the wind strengthens with height, the higher the wind shear will be, and the more favorable the environment will be for severe thunderstorms. Note that other ingredients are equally important for severe weather, and high shear values do not guarantee severe storm development.'
You can see the the upper winds are moving at a slightly different direction , this aids shear. The center of the system is actually moving up near N of Scotland, see previous charts.
Just a glimpse of thunderstorm possibility, will know a bit more tomorrow evening , hard to predict how much or where but will have some idea of general probability.
