    Surprised at how wild it has gone here in the last 15 mins with frequent gusts over 40 knots. Quite the racket.

    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.

    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.

    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.

    It's a small circulation simulated by the upper atmosphere. Jet stream coming in from the southwest and winds blowing from the west in a much lower hpa.

    Anyone remember a storm that developed on St Stephans Day back sometime in the early 90' i think.
    It was very bad for a good part of the day with lots of damage .From what i can remember the NW got hit the worst.
    The next morning it snowed and i remember the electricity been been out for a day and a half because crews could not get to faults because of all the snow

    All quite again here now. Top 10m mean speed from that little spurt was 26 knots with with top gust of 45 knots. Nothing particularly heavy shower wise which makes it all the stranger.

    I would imagine most of the snow would be south of Dublin to Galway. I'm hoping it moves north by about 100km so we can finally see some flakes.

    im south D by the mountains anyway, near Dundrum hehe

    Hope I am right when I say that it may have been 1998. Really kicked off around lunchtime or just slightly after in Mayo and next day awoke to a nice fall of snow. Power gone for a few days after.
    Back to this evening- was fairly wild here about half an hour ago and in the real heavy squalls of rain that were beating off the window, I could make out either the very odd sleety flake and a little bit of hail mixed through it also. Has quitened down a bit again here.

    Leave kittyn alone. She's a lady. Everyone is entitled to wish for snow, be it Dublin or Skibereen.

    Ninja snow that was!

    I remember years ago Dublin Kilkenny and Wexford nearly always got snow in the winter.

    Galway and Sligo too...

    Had it here in North Tipp earlier too. Was looking at the radar at the time and it looked like a squall line had developed. Still seems to be intact across the Midlands.

    We had some hail not too much. Heavier hail a few miles South

    5mm of rain so far from this

    I'll say updated totals each day but hope my rain gauge survives

    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 .

    Should this be a concern?
    Roughly where will the 'eye' track overland? How big is it?

    Well to the north of Ireland. It will hit Scotlands west coast.

    According to Arpege we'll be under -4 ish 850 hPa temps for a while tonight so some sleet likely in places, snow confined to above 700m asl. Milder air gradually moving in during the morning.
