Met Eireann ignoring Kilkenny in their snow/ice warning, we have a few cm of snow on grass, ice and a light covering on roads/concrete, maybe due to south Kilkenny and Kilkenny city. North Kilkenny has snow.

M1 is very bad north of Dundalk

Ulster really got the bulk of the action, with 26 cm of lying snow at Lough Fea (225 m) and 17 cm at Glennane (161 m) this morning. Their automatic stations continually reported snow in their hourly synops. The instruments are pretty accurate, so the Ballyhaise report was probably correct at the time of observation. If there was snow between observation hours then that will have been missed. We don't know at what time that person was at Ballyhaise so we can't check.

It is wet-bulb temperature, not dewpoint, that is most important for snow. If wbt is much above zero then snow will probably melt. WBT is around 1/3 of the way between temperature and dewpoint, so even with a dewpoint of -2 it probably won't snow if the temperature is +2 °C as the wbt will be about +0.7 °C. So to be absolutely sure of snow I would rewrite that table yesterday as

Temp.........Dewpoint
+3...............-6
+2...............-4
+1...............-2
+0...............-1
-0................anything

I'm not sure what exact "Ballyhaise" report you're referring to, but it's an unmanned station. Presumably for statistical and QC purposes, it can't record snow unless its a physical certainty.

I'm surprised by the +2/-2 example as it really has always snowed with such conditions and would stick, excepting roads. I still maintain that from what I've read, dewpoint is still the most critical factor in whether it snows. Wet bulb comes into it for me to see how it will accumulate or not. Its I suppose a pedantic point but certainly snow will be the precipitation with any kind of negative dewpoint in virtually any case with air temp below 3 degrees.

In other news, there has been a very healthy snow shower here in south Louth which has taken a tufty inconsistent 1cm covering to 3cm now. Looks beautiful in a gentle westerly breeze.

North Louth. Stuck in the house, quite rural, due to two road accidents in one direction and an impassable hill covered in slushy snow in the other. No worries in that fuel supplies would cover 3 months and food is good for at least 2 weeks - not that this won't be gone very soon. It's now snowing again and windy. Not overly cold - as often happens with snow.
The south west were hunkering down but we got the weather!
I'm glad that snow lovers got what they wanted but, as someone in his seventies, my concern is to ensure I don't fall and to figure the handiest way of clearing the paths and driveway

Sadly the precip is going to turn steadily to rain or sleet from the north.. 850 wet bulbs go to 3 or 4 for a time in the north.

Looks like there will be one of the most major snow events in last few years (barring 2010) on Monday/Tuesday.

Still snowing in North Meath/Kingscourt - beautiful! Defo a Snow Day here ...:D

Haha, I wouldnt get my hopes up, the atlantic throws all sort of crap at us:P
Mt and Met Eireann's forecasts are contradicting for monday.

If the forecast stays consistent until at least friday night, I would then go buying my snow shovels.

Limerick will never get a warning from MetE again after all the drama from the last wind event/nonevent. We're in the bad books for giving out!
