Just for Fun: Overnight Low - January 8th-9th 2021

This thread will get a frosty reception OP

I'll get my coat :pac:

Kilkit -5.2
Naas -6.5
Oak Park - 7.2

I think Malin Head will come in at the warmest around 3 degrees.

Naas -5.5°c
Durrow -6.4°c
Tullow -7.2°c

Tullow -7.7 because that's the temp I said for the monthly weather forecast for mt hahaha

E: make it tullow, oak park, and carlow if three are needed, all -7.7

-9.1 at Danno's location, -8.5 somewhere else within 50 km, I don't know the co-op network in much detail, but among the official stations, -7.4 at Oak Park.

Dunsany -10c
Mullingar -9c
Gurteen -8.4c

Steady at -4 minima the last 2 obs, talk of -10 at any given station is a bit fanciful.

Oak park -7.1

I'll just leave this here and see if it verifies (SW Laois):

Dunsany -9.3c

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.
