I see more overnight temperatures than anybody since that's when I'm active and preparing forecasts. So I can confirm that normally, the lowest temperatures there (as anywhere else really) occur just around sunrise, certainly in the three hourly obs that end with sunrise. There are of course exceptions, if cloud moves in over the entire country then most minima will be the hour of last clear skies.

As to dew point indicating likely minima, this is a reasonable guide but there is a tendency for temp/dp couplets to drop a few degrees after midnight, so a minimum dew point of -6 now does not guarantee a minimum of -6 later.

Then with regard to this contest, I would also point out that the auxiliary network generally runs a bit colder in terms of extreme low, one or two of the stations may be somewhat "frost hollow" situated and I've factored that into my guesses.

No wind tonight. No cloud either.

.

Yeah, that's what I was figuring. Dewpoints were about -4 or -5 earlier, so I reckoned it would drop a couple more overnight, limited by the already very icy conditions. At midnight now they're ranging -5 to -7 in the midland stations. Will be interesting to see how much further they will drop.

Cmon -10c cmon!

You're not that far fetched are you?

If it doesnt get too cloudy Mt Dillon might go there but I think it might get less cold there by 5 or 6am

Looking at traffic website its -7.7c in Monaghan

Folk's, we've discovered a new national sport - cheering on weather stations.

I guess it's what lockdowns does do to the soul of once sane men (and women).

If we had precipitation at the moment would we be flooded with snow. Or would it cause warming?
