Colder this week, some wintry/snow showers, widespread frost and ice.

The more severe cold of this current spell has not arrived yet, the leading edge of it has recently moved through Scotland and is starting to show up in Northern Ireland now. So I would hold fire until we see the temperatures especially overnight lows next 4-5 days. This is not going to rival Dec 2010 for cold or snow but it may be the coldest December spell since then.

At Portglenone (north end of Lough Neagh) I note that temps fell from 3 C to 1 C around two hours ago as this front passed, and temps in most of NI are now between 0 and 1 C. So there's a good potential here for sleet and snow to develop as this feature continues to move south overnight. Even small amounts of this can render driving hazardous, in fact small amounts may be the most dangerous since some motorists will expect normal traction and encounter black ice. The areas most at risk are probably the midlands and inland north to central Leinster. If it becomes clear ahead of this front in the inland south and then clouds over, that could also lead to black ice formation. Best chance of seeing the Mars-Moon event already mentioned by spookwoman earlier in thread would be inland south and southwest. As mentioned, timing of disappearance of Mars is around 0455h and reappearance around 0555h. Moon would be fairly high still at that hour in western portion of sky on its way to setting in northwest. This is an unusual occultation in that the moon is full and Mars is at opposition so it's a perfect alignment of four members of the solar system. (all occultations are by definition an alignment of three but not often the Sun as well). Hoping to see it here during the evening but rather cloudy at present (local time here being 3 p.m., because of the difference in perspective, we would see this at 03z to 04z or two hours earlier in universal time).

I disagree. Three or fours days of temperatures struggling to get above zero or staying just below on some days is quite unusual for December. So it's understandable there is a thread about it. Also given the potential dangers of freezing fog and black ice it's right that Met Éireann have issued a warning about it to the public. Either way you slice it is an event worthy of discussion. The November mild was unusual but there was no dangers associated with it hence no real media coverage. Also milder weather does not generate the same interest as its rather obviously not a infrequent occurrence here, hence why there was no dedicated thread for the November mild, but I am sure it was commented on by a few posters here.

Thundersnow!

0.9c here in Waterford, humidity seems to be on the rise.

Just in case you forget, RTE is here to help

2.2C out there now in North Kerry.

100% chance of snow between 6 and 7 according to the smart phone…. Unlikely

Sleet here in Kildare with flakes falling

Light rain falling in Tullamore.

There was a frost and some freezing fog earlier.

Temp around 1c.

Wicklow could see some decent snow this evening for a brief period.

Surprised temp hasn't dropped below zero overnight.

Currently 0.4, low 0.2

No frost on car

I won't have to break ice on the rain barrel to have a wash this morning 😀

There's a real feel of "snow" in Waterford this morning. Beautifully cold, frost covering.

Not sure if we have a very light frost but the colour of sky would indicate if we were expecting participation you would be expecting snow

0 degrees and raining in Tullamore. Just looks miserable. Had the drone charged and ready to capture a misty frosty morning. Maybe tomorrow.

I love a bit of cold crisp weather, but I’d love it more for Christmas Day than right now. Anyways I’ll take what we’re given, and I’m hopeful for a dusting of snow as we do get that every year for the kids, so fingers crossed.
