December CET

[paul tall]

-3.6 here, LOL.

[kold weather]

-15.6C at Pershore at 18h00. Good Lord.

Already some amazingly low temps out there, that figure is amazing though for this time of the day it has to be said, Benson will probably be very cold as well tonight given its at -10C...

I think tonight is going to be every bit as cold as last night unless cloud cover in the east reduces the chances...

[Snowyowl9]

ECM is overpowering atlantic freindly from as early as T120...UKMO looks much better if any hope of a record cold is on becuse ECM would only give the coldest december since 1981...

This run actually which would give severe flooding with all the snowcover.

Actually the ECM is a little better then its 00z run as we do get a weak NW airflow, not cold but by 240hrs we'd probably get 2 days of CET between 4-5.5C which with adjustments possibly would be nearly enough to take us below 1981...

Its going to be tight if the 12z ECM is right however...

Most other runs bar the Nogaps keeps the cold long enough to probably ensure a sub 0C month...

[Nick L]

-10c here already, the CET is going to take an absolute hammering tonight.

[West is Best]

Northern Ireland just recorded its lowest ever measured temperature.

Subject to official confirmation but Castlederg is currently reading -17.7C beating the previous record of -17.5C set on 01st January 1979.

Some bad news for you WWB, Pershore got up to -8.2º today so the lowest December max in England still stands. Always tomorrow though.

Lol true. Suspect the advancing snow in the south-west and south may put paid to that tomorrow but maybe not.

16 Met Office stations below -10C at midnight, some sort of record? Pretty damn amazing either way, given that there have been whole winters in the past where -10C hasn't been reached anywhere!

Even London is dropping away like a stone - Northolt in north-west London is now down to -11.9C at 1am.

Temperatures at other sites in and around London as of 1am:

Gatwick: -11.0

Kew Gardens: -8.2

Kenley: -8.1

Heathrow: -7.3

Olympic Park South: -5.7

Hampstead: -5.0

London City Airport: -4.0

St James's Park: -3.9

If Northolt carries on in this vein, it could well rival, if not beat, some of the low minima last recorded within Greater London in Jan 1987 - can anyone confirm this? Mr Data?

[Optimus Prime]

Lowest London minima -9.1c 1987 January.

[drfeelgood]

Lowest London minima -9.1c 1987 January.

Thanks for that. Which station was that? Heathrow?

Great, so Jan '87 is well and truly beaten as far as London is concerned!

What an exciting December we're having!

Actually the London record is -16.1C at Northolt on 1st January 1962.

At least if this is anything to go by: http://www.personal....962_weather.htm

Maybe the January 1987 figure refers to Central London only?

It might be from the Met Office's rooftop station (which unsurprisingly always records higher minima). I'm not sure though so if someone could confirm the station, would be great.

2am update:

Northolt continues its descent, albeit at a slower pace....now -12.2

And even St James's Park in central London is now down to -5.2.

That means all London stations are now below minus 5.

That's quite a feat in December, considering that in most recent winters minima in central London struggle to fall even below minus 2.

[Cymro]

Currently 17 observation points in the uk below -10

With a further 7 very close within 0.1 - 0.6 degrees of getting below -10. Very cold indeed widely.

[ZONE 51]

Overall 1.9c

-1.9c thought i missed something!(-)

[Optimus Prime]

-9.1c is the record for Central London I 'think' at ST Jamses park. The all time low for London is around -23c many hundred years ago even then it was a large urban centre.
