The front doesn’t seem to be heading as predicted. The band to the north that is supposed to be heading South is heading SE.

None of the charts should be taken as gospel, they just give a rough idea of what may happen ...... Mother Nature will do as Mother Nature wants to do no matter what we would like to see .......

I was going on the charts which did show snow for me.

The Met Office have a warning out for fairly widespread snow but I am not seeing it. The precipitation isn’t heavy and appears to be evaporating.

Reposting below what I said here this morning regarding the UK Met Office forecasts for your two nearest large towns, Coleraine and Limavady which contradicted what you said that same Met Office had forecasted for your location. By the way, you yourself said that the Met Office warning is for fairly widespread snow in northern Ireland. This is exactly what like like is happening tonight.... Snow almost everywhere apart from low lying areas in the North and West of the province

I had a look on metoffice.gov.uk and it doesn't show anything more than sleet for both Coleraine and Limavady for tonight with temperatures in the overnight period between 1 and 3c for those locations. Now, if you are between those towns and have that high ground to your north, it "might" sway you to the correct side of marginal but 50m ASL might not cut it. Location wise, if I were to draw a line from Limavady and Coleraine, would you live somewhere along that line? Would you be somewhere along that line but further inland and if so, how much further? On Google Maps, I see a little townland called Ringsend east of Limavady and south west of Coleraine. If you live near enough to this area, you might have a far enough land fetch for snow to fall and accumulate with a north or northwest wind source.

I'm not far from DA and it feels around that. I'm not sure whether the wind (even though pretty calm) is fully off shore yet actually, looking at the radar showers in the Irish sea still have a slight westward tint.

-4c from -4.6 earlier, that band of precipitation looks fairly miserable on ME's rainfall chart

Agreed. The north seems to be getting more substantial precipitation.

Nah sea surface temperatures are due to remain high in your region for at least the next few months. As a result, coastal areas of the NW will be too marginal for proper snow for the rest of this winter unfortunately. Especially in your location that's so prone to marine layer mixing.

Where's MountainyMan?

He should be getting a good sprinkling now if ME radar can be believed.

A very steady -2.6C here, South Ros.

Light drizzle west of Galway. Very light.

is it this cold so early on because the cold has become "entrenched" because it's been cold since Christmas Eve? I wonder how low Mullingar would have been tomorrow morning if there was no front crossing the country.

-2.6 with dewpoint of -2.9 at my station in Carlow Town. Hoping for a dusting if it comes down this far but expect sleet at best.

Actually if looks like snow but has gotten noticebly warmer too freezing here all day.

UKMO aviation chart for 06Z has the cold front lying Belfast-Mullingar-Dingle. Weather ahead (southeast) of it (NW of line Wicklow-Sherkin Island) is isolated moderate snow (vis. 800 m), otherwise sleet.

Yeah, it's a cumulative effect, also seen in the lower daily maxima.

Still northeast in arklow
Down to -0.8 despite the cloud near the showers and the breeze off the sea

Officially the coldest night of this winter so far at Durrow with -4.7c currently. Bring on that darn front!

That’s only up the road from me and I’d agree it’s saying -3 here.....it’s a crystal clear sky and from the hills here you can actually see the front away in the distance to the north with almost northern lights like streaks across the sky at the leading edge it is very nice to see

I'll take that tbh. At best I expect to see light - moderate snow at some point.

Why are people taking about not receiving snow yet. The warning is valid from 11pm when the main band comes down around midnight or just after pushing southwards. Early days yet.

At 10 pm Castlederg (51 m) was reporting a rain shower, despite temp/dewpoint 0.1/-0.7 C.

Very light rain in collooney, Sligo in the last 30mins.

There is actually a bit of a warm sector just ahead of that cold front. It was analysed at 12Z, gone at 18Z, but some remnants of warmer air ahead of the front not surprising.

Just went for a walk in Rochestown, Cork. Hard frost out there - very much a winter wonderland out.

Not expecting much where I am but it would be nice to wake up to a light dusting tomorrow. Just hope it makes it this far intact. Dublin 16
