I'd say your parents were worrying about getting to the hospital:) I have access to archival newspapers lately and they're brilliant for confirming what's in my memory, some dates are correct and then some fixed in my mind are off. But that 13 December 1981 stuck in my mind and just the similarities with now.
The period from the 1st to 4th was cloudy and mild with extensive fog and patches of drizzle. A wave depression affected the southwest on the 5th after which a northwesterly airflow set in. Squally showers occurred, some heavy especially in northern areas on the 7th. Weak troughs of low pressure affected the country between the 8th and 10th and high pressure dominated the 11th and 12th. There was extensive freezing fog during these spells Strong winds and widespread heavy falls of snow or rain occurred in all areas on the 13th, associated with a depression centred over southern areas. A ridge of high pressure developed on the 14th and the period to the 19th was very cold and dry with general air frost and sharp to severe ground frost. Mild air in a complex frontal trough affected the country during the 19th and there was widespread heavy rain, especially in southern regions. The period from the 20th to the 22nd was foggy with spells of drizzle and there was light frost at night in some places. Subsequently, a cold easterly airflow was established and widespread frost became severe between the 23rd and 25th. A strong south to southeast airflow set in during the 25th. The weather became mild with extensive rain and drizzle. Winds backed easterly on the 28th and there was widespread heavy rain on the 28th and 29th. Rain became scattered on the 30th and 31st and some frost occurred at night.

I thought the figures would be a bit closer together or something. Absolutely no idea what dewpoint really is, in case that wasnt obvious already from my post

You have to feel sorry for the poor Dubs, they’ve had no real snow of note since late 2010. Looks like it’ll miss out on this one as well. Hopefully there’ll be a decent easterly at some point this winter to fix that.

I mean changing forecast about 5 hours before the so called event is pretty bad. I know there are variables at play but they surely have access to a lot of weather models, you would expect a met service to be able to predict better within 24 hours. We will see what happens from here but it’s been like musical chairs today moving warning from one county to another. You would most certainly expect it 2 or more days out but not within 12-24 hours

Gaoth Laidir wrote: » Wet-bulb temperature is more important. It's just above half way between dew point and temperature (closer to temperature). A wbt of less than zero is needed, though snow can survive up to around +0.5 °C. If temperature is 4 and then dewpoint needs to be around -5 for the wbt to be around 0.
