December C.E.T

[RedShift]

Redshift 06.1c, 153

[reef]

Im predicting a mild month, though consistently mild compared to last year which was exceptionally mild during the first half and saw that minor anticyclonic correction later on.

6.6C

[beng]

Not had time to look at this in too much detail, but I'll go for:

4.0c

Generally wet and average temps to start, possible cooler and more blocked from the East around of just after Christmas.

[Cecil Hogmanay Melchett]

Im going for a very wet and mobile December with CET of 7.1 !!!!!

[Cumulonimbus Tower]

6.1 CET for December

(7.1 mid month punt......)

[Mr Maunder]

December....now it starts to get tougher, the margin for error could be quite large!

Despite the projected warm start I am going for 5.7c. I do not expect it to be quite as mild as projected, with a marked cool down as the month progresses. (Hopefully the vortex will not get established over Greenland - we shall see).

Can I add my thanks to all those to take the time to organise these monthly CET competitions. It certainly keeps SF and WIB occcupied!

After 10m minute of research im going for 6.2c tempted to go higher but will stick with that.

[Great Plum]

I'll go for 6c on the dot please...

[LadyPakal]

My punt is for 5.2.

Really tough call here, confused massively by the huge upward hit the CET is going to take in the first week or so and a possible downward correction mid month to Christmas.

SSTAs to our west are running at +2C to +2.75C.

We have a good steer for westerly flow over the next 7 days. With a -AO kicking in, it'll take time to evolve a -AO / -NAO but this will pop up as stratospheric anomalies kick in and a mid month correction takes place.

Analogues for Atlantic SSTA (which include the warm seas to our west) suggest nothing far off normal.

Temperature anomaly analogues:

z500 pressure anomaly pattern:

This equates to a huge potential spread. I make it +2 to -0.2. Mid point suggests somewhere around the 6 mark.

My projected AO is -0.6 to -0.8, more negative than November and a stronger signal for average or slighly below. Therefore average and an allowance for the damage caused the first week.

6.0 C please.

[JohnAcc]

I'm going to revise my estimate northwards I'm afraid. I'd like to increase it to 6.1 please

Rgds, John

[BLAST FROM THE PAST]

I'm going to put mine in just before the witching hour...and its going to be incredibly close to average.

[Joneseye]

really difficult to make a sensible punt this month - the toughest for a while.. gotta go with instinct and this tells me 5.9C. I fear I may be calling well under and expect another month of watching the colder 2nd half pull back the milder 1st half.

[Polar Continental]

Looks above average for the first week, but looking for a switch around afterwards, 3.5c for me please.

Paul

[Mark Bayley]

I think i will change mine from 4.9c to 5.8c please

Thanks

Mark

[IRON-BRU]

6.7c for me please.

[BLAST FROM THE PAST]

The northern blocking didn't set in as expected on my Dec thoughts but certain factors I'm still confident of. I will plump for 6.2C .

BFTP

[Terminal Moraine]

I'll hopecast that the very mild start to December doesn't last too long and is offset by colder weather after about the 13th. This leads me to make a prediction of; 5.3c

T.M

[Paul]

I'll have a punt this month - 6.1c

[HighPressure]

Its looks on the warm side at least to start so 6.3c for me!

[Michael Fishermans Friend]

Looks fairly mild for the foreseeable future, and generally when it starts mild it isn't usually off set by colder spells. So probably one of the mildest for some time, so I'm going for a CET of 7.0C

[phil nw.]

My December Entry is 5.7C.

Thanks to SF,JO and others for all the time given to running this Comp.

[Mark H]

6.2 for me this month.

Cheers.

[J10]

Given that an above average in terms of temperature start to December now seems likely, I'm going for 6.1c , which is 1c above the 1971-2000 mean.
