    I agree nothing that cold in the works this side of midnight, I think the question posted by Danno is a little ambiguous. If it covers post sunrise tomorrow, as GL alluded too, coldest part of this spell will be post 6am so -9c is possible. We still have snow cover in the driveway from Thursday.

    Often the lowest temps of the night are just before sunrise, and as Obs are taken at 9am at climate stations, its unlikely that after 9am would go lower.

    Hope this helps!

    Oh, it's just for fun anyways! :D

    Surely the event we are guessing for is the lowest temp between tonight and tomorrow morning (say up to 9am). Most guidance suggests lowest temps occuring sometime between 04:00 and 08:00 tomorrow morning.

    Naas, minus 8

    Dew points might just fall a little lower than minus 6, we shall see.

    Relatively still air and humidity is a little lower than usual.

    Meanwhile, Kilcogy -6.4c, Dunsany and Navan ACS -5.8c. :)

    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.

    Knock knock, just hit -6.0c here in southern Laois...

    https://www.wunderground.com/dashboard/pws/ICOLAOIS2/graph/2018-02-28/2018-02-28/daily

    and

    https://www.wunderground.com/dashboard/pws/ICOLAOIS2/graph/2018-03-1/2018-03-1/daily

    was during Storm Emma where -9.4c (AWS) and -9.7c (Stevensons Screen) was reached.

    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

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